To transport the waste materials from th e car's engine to the tailpipe is the main function of the Chevy Exhaust System. The tailpipe is found on the rear portion of the system in which exhaust materials are brought out in the atmosphere. For older models, exhaust has catalytic converter, one or two exhaust manifold and mufflers. Manifolds are mounted on the cylinder head of the engine which serves as the path of the gas from the exhaust ports on the cylinder head to the catalytic converter. A car's muffler is a component of the exhaust system that reduces the sound produced as the car's exhaust is vented into the atmosphere. Highly efficient mufflers provide easy passage of exhaust gases although it may produce louder sounds.
Straight through muffler and reverse-flow muffler are just two of the varied muffler types. Reverse-flow mufflers are oval in shape with multiple pipes and chambers. Muffling of the exhaust sound needs four chambers and one double jacket. Exhaust gas produced is carried to the third chamber, directed back to the first chamber and thrown out into the tailpipe. Straight through mufflers are made up of a central tube with several openings that directs the gas into the outside chamber lined-up with insulating materials to trap the noise.
Latest car models use high-performance exhaust system with one or two mufflers and tailpipes called cat-back exhaust or dual exhaust system. Improved breathing capacity is improved using this type which also leads to greater horsepower production. Added piping, mufflers and tailpipes are used which makes it easier for the exhaust to flow freely, decreases backpressure and enhances the vehicle's driving mechanism. Due to improved breathing capacity, less exhaust gases is left on the engine after every exhaust stroke. Thus there is better space for extra air and fuel mixture to power the system.
The car's exhaust system burns petrol or diesel to keep the vehicle running; however, it can produce dangerous gases that can harm the environment. Unburned hydrocarbons and carbon monoxide are the common end result pollutants of older petrol fuelled vehicles. Latest studies identified certain microscopic particles produced during combustion process that can cause big negative effects on health. Ozone is also one of the most harmful pollutants that results from the reaction of sunlight and other polluted chemicals. Exhaust pollutants only become harmful when it exceeded the standard level. The most common air pollutants are Nitrogen Oxides, Carbon Monoxide, Sulphur Dioxide, and Ozone.
How to Maintain Your Chevrolet Exhaust System Properly
Although the farthest thing on your mind when it comes to personal safety on the road or engine performance is your Chevy's exhaust system, it's actually quite relevant and important in terms of either topic (or both topics, to be honest). Gases are created whenever your engine combusts air and fuel in order to run. They then have to be vented from your engine through your car's respiratory and excretory system, its exhaust system. With that in mind, what should you do in order to maintain your Chevrolet exhaust system in such a way that it continues working properly every time? Here are the answers.
Get your Check Engine Light checked.
Your emissions system is actually related to what's indicated on your Check Engine Light. If it's blinking or turned on, then there's probably a problem (and sometimes it's your exhaust that's undergoing shenanigans). Your OBD (on-board diagnostics) is the one that monitors what's going on with your engine components, which includes your exhaust system. Therefore, one dependable way of making sure everything is one the up and up with your exhaust is by checking if there are any emissions-related error messages on your OBD interface. In particular, this computer is a handy way of preemptively fixing exhausts problems before they could worsen (like issues of breaking down or deterioration). It can activate when there's an oxygen sensor failure or bad catalytic converters.
Do some exhaust cleanup to reduce emissions.
Depending on which state you live in, your car, van, SUV, truck, or jeep will need to deal with emissions reduction or else you might end up going over regulation limits on emission rates. You can fix your exhaust issues by exhaust cleanup or having your mechanic take a look at your system in order to keep your vehicle from becoming a gas belcher. To clean out your exhaust manifold, you need to detach it from the system then brush it with lacquer using a toothbrush and an electric grinder to break up the debris. As for exhaust tips, you need special cleaners like degreasers and metal polishing soaps to get them spic-and-span.
Fix leaks on your car ASAP before they could worsen.
Your exhaust system is subject to lots of vibration, high temperatures, and intense pressure. This is the recipe for disaster in the form of leak development in various parts of your exhaust, from any of the tubes to the tailpipe. The exhaust manifold is one of the first areas where leaks could develop. It's either the gasket starts to fail and leak or the manifold itself might end up cracking under pressure. A lot of things could happen. The different pipes in your exhaust system can also end up with leakages for various reasons (mostly due to pipe failure or corrosion due to road salt exposure), which you'll have to seal up with gaskets too.
Identify broken components and repair them early on.
Another important tip when it comes to preventive exhaust maintenance is recognizing when certain parts of your system is failing and thusly repairing or fixing them before they lead to total exhaust breakdown. In order for it to work superbly, your emissions system requires a significant number of components all cooperating with each other in total harmony. Even the supplemental parts have their important uses, from exhaust hangers that secure your pipes to your car's underside to the bolts that hold them together. Even the "little things" could lead to big problems if ignored.
