How Catalytic Converters Helped Transform Automotive Pollution

The automobile was developed in a period of human history where we paid very little attention to the environmental impact of the things we did. As a result, the hazardous waste products expelled into the air by internal combustion engines were ignored. This worked for a while because there were so few internal combustion engines chugging away. As the number of automobiles exponentially increased, the danger from toxic fumes grew alongside a growing awareness of environmental concerns. The solution to the problem of these toxic gases was the catalytic converter.

The first catalytic converters came into popular use in the United States during the mid 1970s. These were two way converters used to eliminate the two pollutants that came directly from the engine – carbon monoxide and hydrocarbons.

Carbon Monoxide is deadly because our bodies can not differentiate it from Oxygen. We can breathe it and our bodies do not panic even though we are being deprived of air. A person succumbing to Carbon Monoxide poisoning simply feels sluggish and the sudden urge to sleep.

Hydrocarbons that are released by an internal combustion engine are simply remnants of the fuel that did not get completely burned. These remnants are the visible particles that we all think of when we imagine a vehicle with poor emissions. While certainly deadly to people, they are less of a danger than Carbon Monoxide in that we can detect and try to avoid breathing them. The larger danger of Hydrocarbons is to the environment. Once in the atmosphere, these pollutants are responsible for phenomena like acid rain and smog.

Catalytic converters use a chemical process to convert these harmful chemicals to the more benign Carbon Dioxide and water vapor.

Scientists eventually realized that two way catalytic converters were inadequate because engines produce a third pollutant – Nitrogen Oxides. These Oxides are created when the heat from the combustion process forces Nitrogen and Oxygen to combine in a process similar to the operation of a catalytic converter.

Modern catalytic converters are three way, in that they function to eliminate all three classes of pollutant. The catalyst, or material used to make this conversion, is usually palladium or platinum. The current three way catalytic converter has become standard for decades now. With growing concern over the amount of Carbon Dioxide found in the atmosphere, it is very likely that scientists and engineers will try to further increase the effectiveness of catalytic converters to convert Carbon Dioxide to a different compound.

Difference Between A Direct Fit And A Universal Fit For Your Vehicle

Understanding what a catalytic converter is, and what it does within your exhaust system, is important for you to distinguish the best options when having to choose the difference between a direct fit and a universal fit for your vehicle. The propose of a catalytic converter is crucial for converting harmfully toxic gases, which are produced during the combustion of gasoline and diesel fuel, into carbon dioxide and water vapors, and to reduce nitrogen oxides. In this way, harmful gases such as hydrocarbons and carbon monoxide are meant to be rendered harmless, if the exhaust system if functioning properly.

Can an inefficient exhaust system hinder the ability of modern catalytic converter to reduce nitrogen oxides, and to convert harmful exhaust gases into water vapor and carbon dioxide? The answer is yes. In fact, the difference between a direct fit and a universal fit for your vehicle can improve the effectiveness of the catalytic converter. And, at the same time increase your engine’s overall performance. Here’s how.

To ensure that you’re current catalytic converter is operating at peak performance, or you are considering installing a new one and want to get the most effective use out of it, then you should know the difference between a direct fit and a universal fit for your vehicle. Below you will find a description and an explanation distinguishing the differences between a direct fit and a universal fit. But first, you need to understand the basics of how an exhaust system works.

Universal fit and direct fit catalytic converters are much like comparing a custom exhaust system to a generic exhaust system. Professional exhaust fabricators Melbourne have the knowledge and the ability to custom design an exhaust system for almost any type of vehicle. The purpose is to decrease engine noise, increase vehicle performance or to meet ever growing governmental standards. The purpose of generic exhaust system components is to reduce noise; they are not designed to increase engine performance. Understanding this will help you to know the difference between a direct fit and a universal fit for your vehicle.

Universal Fit Catalytic Converter – As the name implies, a universal fit means that a catalytic converter is generically designed to fit various engine models of cars, truck, vans and station wagons. The pros and cons of a universal fit may not be obvious to the untrained mechanic or exhaust fabricator. Most vehicle owners don’t even know what a catalytic converter does, let alone the benefits and negative effects they can have on engine performance. So, what are the pros and cons? The pros are easily understood when considering price and availability.

Universal catalytic converters are usually less costly than direct fit ones, however, the cons are observed in reduced engine performance. Why is that? Custom exhaust system components are specially fabricated using specific length and pipe widths, to take advantage of the vacuum that hot gases produce when they leave the exhaust manifold. Universal fit catalytic converters can hinder the effectiveness of a custom exhaust system, thus affecting their efficiency as well.

Direct Fit Catalytic Converters – These are specially design to fit your model of car. Direct fit catalytic converters are the ideal choice if you want to get the most out of your engines performance. Locating a Melbourne exhaust centre, one that specializes in fabricating custom exhaust components is important, if you want to install a direct fit catalytic converter into your vehicle to improve engine performance.

Now, much like all your prized possessions, your car needs some personal attention and care from time to time and if you’re like most car owners, you’re always looking for ways to improve the performance and efficiency of your vehicle.

One easy way to do this is by upgrading your 4×4 exhaust system. By doing so, you can increase your car’s horsepower and gas mileage, and reduce harmful emissions at the same time.

Tips to Remember

Ready to breathe life back into your car’s old, outdated exhaust system? We have a few tricks up our sleeves to make this transition smoother for you and your car-

Size Matters

Make sure your 4wd exhaust system is the correct size for your engine. If it’s too small, it will restrict airflow which in turn will hurt performance. On the other hand, If it’s too big, it can actually negatively affect engine performance.

Hygiene Over Everything

Keeping your exhaust system clean is crucial. Build-up of soot and grease over the time is one of the primary causes of exhaust choking which can end up shortening the life of your exhaust system.

Fine Tuning is Important

Make sure your exhaust system is properly tuned. A properly tuned system will improve airflow and scavenging, which can lead to more power and smoother performance.

Time To Go Turbo

If you’re looking for even more power, consider adding a turbocharger or supercharger to your system. This can significantly improve performance. However, make sure you get the right size for your engine.

Nothing Beats a Good Muffler

Lastly, make sure you have a good muffler. A quality muffler can significantly reduce noise and boost exhaust performance at the same time.

Whether you have a custom 4×4 exhaust or a standard 4wd exhaust, these tips will help you get the most out of your system.

If you’re not sure where to begin, we recommend a reliable auto-repair shop just like the one we have down at Melbourne.

Understanding The Basics Of How Motorcycle Exhausts Work

A large number of motorcycle enthusiasts these days are do-it-yourselfers and are very knowledgeable about the functioning of their motorcycles. Of course, this skill develops with the hobby, and later on becomes a passion that is necessary to truly immerse yourself in the motorcycle world, to get the most out of it. Still, a sizeable number of newbies to the motorcycle world need some type of introduction into the workings of motorbikes, especially over topics that go beyond the basics of maintenance and general care.

Issues like the basics of brake calibration and understanding how motorcycle exhausts work are sometimes left undiscussed, unless one takes a crash course in mechanical engineering or automotive repair. However, there’s an easy way to go about understanding how motorcycle exhausts work. Aside from watching various videos online that attempt to simplify the process, here is a brief article on what you need to know in order to understand the ins and outs of motorcycle exhausts that could help you some day.

Motorcycle Exhausts – Their Types And Functions

What is a motorcycle exhaust? A motorcycle exhaust is a complex device generally composed of piping, attached to a motorcycle’s engine. Sometimes these are chrome-plated for aesthetic reasons. However, exhaust systems can also be made from aluminum, steel, alloy, carbon fibre, and even titanium.

What does a motorcycle exhaust system do? Motorcycle exhausts mounted on the engine help to re-route noxious gases away from the rider and passenger while simultaneously muffling noise and improving engine performance. Actually, a well-maintained exhaust system can vastly improve overall engine performance and prolongs the engine’s life.

What kind of exhaust systems are there? There are basically two main kinds of exhaust systems available in the market today; a mufflers-only exhaust (properly referred to as bolt-on or slip-on system), and a full exhaust system. The latter one tends to have the added feature of being customizable or otherwise custom-made to suit different specifications and needs.

A third variety is the default exhaust systems that an average motorbike bike is equipped with upon purchasing, which some hard-core enthusiasts consider to be mediocre at best when compared to custom-made exhaust systems.

If you’re looking for a great place to find excellent examples of exhaust systems for your motorcycle, or if you’re ever in need of a high performance customised exhaust system that is sure to rev-up your bike’s speed and overall performance, then visit Trufit Exhaust today: https://www.trufitexhaust.com.au/

Maximising Fuel Economy With The Use Of Headers

Restless see-saw reasoning accompanies aftermarket modifications. One exhaust can extend performance and add throaty noise to the profile of the vehicle, but the change hamstrings fuel economy. A dizzying back and forth ensues as street performance or off-road aptitude is balanced against petrol mileage. Custom headers aid in this scenario by coming down firmly on the engine optimization side of the see-saw. The kit, as we all know, delivers instant aesthetic appeal, a chrome-plated, titanium coated killer look, but function has to match this aggressive profile or the owner only ends up with a better looking stock exhaust replacement. To really maximize fuel economy, performance headers are manufactured to a shape and size that improves engine “breathing.”

A Brief Anatomy of Internal Combustion Breathing

Miniature explosions drive engines, but spent fuel has to move away from the combustion area in order for the next burn cycle to occur. If this discharge routine didn’t happen, then the generated back pressure incurred by the process would cripple performance. A header kit is bolted on as an aftermarket modification kit. It channels this gas away and cancels back pressure, thus maximizing the respiration of the engine. The result of reduced pressure is a more efficient engine and improved mileage, a mechanical and chemical optimization process that reduces petrol consumption.

Not All Headers Are Created Equal

It’s important to remember that a number of approaches are taken with the customization market. Showing off is a big component, which means the custom part looks good and sounds so loud that it sets off local car alarms. Still, the game is also about performance. The purchase of a kit that curves sexily and accentuates the profile of the vehicle is all very well, but is it improving power output without burning more fuel? An efficient header kit balances these requirements, delivering performance, improved cylinder burning, and a smoother ride. Petrol efficiency is a natural upshot of the installation of the kit.

On Getting Technical

There’s a fight for dominance when the spent exhaust gases enter the engine manifold. The multi-tubed header assembly separates this fluid interaction struggle by placing the output exhaust in individual metal tubes, intelligently cut titanium lined channels, as one example, that cancel the back pressure phenomenon and create a more harmonic environment within the engine output stage. A uniform increase in power can then take place, one that doesn’t leverage additional costs in terms of petrol burned.

Benefits of Having Customised and Modified Car Exhaust System?

Car modification work is a huge and all-encompassing subject but it can be reduced to a handful of factors. You’ve bought that new performance auto with an eye on performance, which is the prevailing reason, but you’re also looking for a cost-effective route to adding even more muscle. There are engine enhancements and aftermarket augmentation kits by the barrel load, but, just as with a biological system, this exciting path can be realized even faster by just improving the “breathing” of the roadster. A customised and modified car exhaust system does just this, opening up the airways of the vehicle so it can burn fuel more efficiently and generate pure forward momentum, the kind of power that pushes you back into your seat as it growls with an animal-like roar.

What You Get Isn’t Always What You Want

Aftermarket enthusiasts often purchase a vehicle knowing just how far it can be pushed. They know the factory exhaust system is a utilitarian fixture, one that allows the car to perform as documented by a set of manufacturer compiled design specifications, but they also know how those performance limits can be dramatically shifted into peak performance territory by making a few key changes to the factory profile. A customised and modified car exhaust system represents one of the easiest parts of the car to enhance. All that’s required is the right kit and the knowledge to install that kit. But the benefits of little changes can reap big rewards.

An Engineered Path to Explosive Performance

When you install a custom exhaust system, you’re placing the focus on the output side of the engine. Physics mandates this performance upgrade ethic can only take place when all forces are balanced. Therefore, if you install a heap of beefy parts into your engine, performance figures won’t be realized unless you’ve accounted for the output stage. In other words, more horsepower and torque can only develop if the exhaust is taken care of, thus highlighting the engineering quandary of what to do with an increase in back pressure. Install a widened exhaust channel, taking the wider path all the way up to the engine manifold, and the bolt-on modification releases back pressure, enabling the gas mix to escape, the engine to breathe, and the realization of a big picture outlook that includes superior acceleration.

Hi-flow performance improvements and gas restriction issues aside, the sound generated by a customised and modified car exhaust system can be truly aggressive as the tone and pitch of the exhaust shifts several octaves into the low “growl” spectrum. And, let’s not forget, a single or double exhaust plated in chromium steel creates a certain shiny aesthetic, one that just looks plain sexy.

Tips in Choosing the Best Exhaust System for Your Muscle Car

Muscle Steroid-like power radiates from every contour of a newly customized muscle car, but the brawny outline needs to be balanced. The engine is burning fuel but pressure is being generated as a consequence of the combustion sequence. It’s the job of a performance exhaust system to keep this power cycle intact and energy-efficient by pushing spent fuel (gas) away from the engine. Like the physique of a finely tuned athlete, the engine has to breathe properly while creating energy. Here’s a few key tips for improving performance breathing, for choosing an exhaust system for muscle car enthusiasts.

Good Enough Thinking Has No Place in the Project

Instructional articles tend to gravitate towards the explanation of a product and how to buy the product on a budget, but this cost-effective philosophy will only hamper exhaust customization work. Buy the best muscle car exhaust on the market if possible. If you can’t buy the more expensive option, save for an extra month. The performance gain makes the extra wait and expenditure worthwhile.

Intelligent Engineering Enhances Key Attributes

You’ve spent an age working on your baby, so now isn’t the time to cut corners. If there is an unavoidable need to cut costs, evaluate your options. The first choice is the sound, a roar that screams performance. A multi-chambered exhaust chamber creates this animalistic roar, but there are also perforated configurations and straight-through models, specialized chambers that offer a variety of performance gains. Evaluate that need for sound, but match it against mileage savings, engine efficiency and material quality. A chrome-enhanced T-304 stainless steel exhaust will looks as good as the multi-chambered model, but are there any acceleration or torque improvements taking place? Cosmetic changes are fine for the amateur, but a disciple of the muscle car world usually looks for more concrete gains.

Horsepower and Torque as Twin Obsessions

Don’t get caught in the performance trap. An exhaust system for muscle car aficionados should be a rewarding activity, not one where tiny gains are being scavenged. Start by researching brands and how they relate to your project. Next, temper the performance aspect by looking into the construction of the exhaust. Just as with anything else, the component could burn bright but also burn out way before it should if design integrity isn’t observed. Opt for a durable construct, an assembly of expertly fabricated parts that assumes a triple case profile. The triple housing outline is particularly adept at isolating outer influences from the gas separating innards, thus ensuring both durability and performance.

Choosing the best exhaust system for muscle car installation is a task that takes consolidation skills. Review aesthetic considerations and compare the compiled specification sheet against a short list of worthy candidates. Finally, reinforce visual appeal with physical attributes, attributes that increase tailpipe diameter or even double up the pipes to create a superior aspiration profile.

What Are Ceramic Coated Headers?

There’s a well-known anecdote used in engineering, a fact-based narrative that talks of how the aerospace industry is the source of many of our current products. Time-proven by rocket scientists, ceramic coated headers represent a key technological development, one that was born in space-age rocket research, and one that transfers its benefits from these rocket components to our enthusiast exhaust system market, pushing performance figures to new limits.

What are Exhaust Headers?

Regular vehicles arrive fresh from the factory with standardized parts, components that don’t exactly set performance charts on fire. The engine and exhaust are efficient and road worthy but won’t set any land speed records or generate a grunt of noisy power. Exhaust headers are bolt on pipes, large-diameter tubes that are bent, shaped and mounted as an engine manifold replacement. The effect of this aftermarket addition is improved engine airflow and optimized engine performance through a dramatic reduction in piston back pressure. The headers are designed to draw the eye. The parts mount as a single unit, installing with elegant parallelism to modify the sound of the engine and enhance drive characteristics. As powerful as this addition is, ceramic coated headers take the product to the next level.

Injecting Ceramic-Backed Material Enhancements

The earthen benefits of a ceramic finish begin with heat subjugation, an aptitude for preventing heat-stressed headers from aging when a newly tuned engine pushes the car to the edge. The ceramic finish absorbs heat and ends thermal cycling, a phenomenon that causes parts to enter extreme heating and cooling phases. A high quality header, a kit part that adheres to the above airflow enhancing model, is wonderfully efficient, but a state-of-the-art ceramic coating adds to this efficient profile by infusing the assembly with ceramic, a material that dissipates super-hot surface heat. In turn, as you enjoy your newly mounted ceramic coated headers, the improved thermal characteristics of the product will have a natural knock-on effect, improving performance as energy losses are reduced, losses that can be redirected back toward the engine. The result is a boost in horsepower.

Weighing the Sound and Style Benefit

The coating acts as a protective thermal buffer, but it also functions as a mechanical barrier, placing a hard-as-nails outer layer between the road and this heat-stressed assembly of alloy-reinforced tubes. The coating rejects road salts and prevents corrosion. It stabilizes the metal during peak thermal activity, stopping engine-driven exhaust from acting as a catalysing agent and aging the assembly. The same thermal mitigation attribute protects nearby engine parts and the inner parts of the engine exhaust. In fact, on thinking of the innards of the exhaust, a superior coating adds ceramic protection to the inside of the header, thus protecting the pipes from corrosive engine fumes.

What are Pacemaker Headers?

If you’re wondering about Pacemaker Headers, don’t attempt to puzzle out this term by yourself. You’ll end up visualising an electronic gizmo that’s intended for an ailing heart, and you’d definitely be on the wrong track. This is a brand name, a car enthusiast vendor that manufactures exhaust system headers. Australian built, Pacemaker pipework is built for performance, thanks to a pipe-over-cone feature that edges out the competition.

A Header Refresher

As you probably recall, engine headers bolt on to the exhaust manifold in your vehicle’s engine. The object of the uniquely profiled back pressure reducers is to give each cylinder its own discharge path, with the channels then blending into a single thick bore tube. When you install a header system, you’re taking the load off the cylinders by endowing them with their own outlet channel, one that then combines attractively with its peers to quickly dismiss all exhaust gases. In appearance, the pipes make your vehicle look like a muscle car, but the performance modification can go even further, just as long as you’re willing to select a top-branded manufacturer.

Pacemaker Headers: Redefining Cylinder Separation Technology

Quality exhaust headers, courtesy of Pacemaker, take this byproduct separation principle to a whole other level. First of all, the mandrel-bent pipes are specifically designed to accelerate the ejection process, so the discrete fume streams rocket out of the pipework before the exhaust back pressure even begins to hamstring engine performance. Next, an innovative engineering company enjoys leading the field, not playing follow the leader, so the Pacemaker team have been busy. They’ve added that mandrel-bent profile to the mix, then brought their engineering acumen deeper into the architecture of the headers to deal a blow to the turbulence that develops when these discrete byproduct streams recombine. The solution is Pipe Over Cone technology, a header profile feature that significantly reduces gaseous turbulence so that the gases move unhindered towards the exhaust tips.

A peek inside the vendor-tuned pipes shows a design that doesn’t place a protruding pipe inside the collector cone. Instead, Pacemaker Headers focus on singular innovative solutions, products that curve while never attenuating the exhaust stream as it travels away from the engine manifold. Add to that the copyrighted pipe over cone feature, a design that draws upon the laws of fluid dynamics, and this product family easily gives any other header vendor a run for its money. Built to inject your next bolt on set of headers with added performance, Pacemaker Headers are also long lasting, designed to fit many popular cars, and a product of a dedicated R&D environment.
