Exhaust Systems Explained-What does your Car Exhaust System (Muffler) DO ?

 Exhaust Systems Explained

To most of our customers, the exhaust system is just something that hangs underneath their car and when it breaks it makes a loud noise and costs a lot of money to replace. Well the

second part is true they do now cost a lot of money to replace, especially if you include the catalytic converter in with the price.

 

The first thing that your exhaust does is to transfer the gases produced by your engine from the front of the car (the engine) to the rear of the car, expelling the gases into the atmosphere. In the olden days pre-emission testing days, the gases were a high pollutant, but now because of the new car technology, cars produce far less toxic gases than they used to.

The exhaust system usually comprises of three or four different parts depending on the model and engine size of the car.

They start at the front of the car with the catalytic converter, which is connected via a normal piece of pipe to one or two silencer boxes and sometimes a piece of chrome pipe to add a finish as the exhaust system leaves the underneath of your car. The catalytic converter reduces the amount of CO2 gases that leave the engine, by filtering the gases through micro porous ceramic honey comb type structures, the emissions are monitored through lambda sensors that are screwed into the cat and send messages to the on board computer that all modern cars have.

The rest of the exhaust is pretty simple in comparison to the cat. The exhaust system boxes are filled with a fibreglass type material that quietens the sound made by the engine. In the USA, these are called “mufflers” because put simply they muffle or quieten the sound as it enters the box. Exhaust systems are probably one of the few things that differ in quality, a cheap exhaust system will probably only last for about 18 months, but a much better system say one that is made by a company called “Bosal” will last up to four times, because of the superior quality of the metals used in the making of the parts.

Well starting at the front, a big problem is from the gasket that bolts your exhaust system to the engine. This gasket can become worn and deteriorate because of the high temperature omitted by the engine. When this happens the noise will be deafening, but they are not usually difficult to fix. The next problem is just common old rust. The complete Car Exhaust system is attacked by rust from the day that the car hits the road. Also to add to this is salt, especially here in the UK where we use in Winter in great quantities. Eventually, the rust will attack the most vulnerable parts of the exhaust and a piece will fall off. Stainless steel exhaust system is the only cure for this problem but, they cost two or three times the price of mild steel systems in the first place, so they are not always a viable alternative.

This is an interesting point; I suppose that regular car maintenance has an effect on all your car parts in the end. Your Catalytic Converter care, (CAT) is a crucial part of your vehicle. Therefore, is fitted with your engine and the rest of the exhaust system.Thus, some are attached to the manifold, onto the engine, these are known as manifold cats, and some are fitted at the end of a short front pipe on the rest of the exhaust system.

Bigger models of cars sometimes require two cats, cars such as BMWs and MERCs usually have two cats fitted, (very expensive to replace).Catalytic Converter care

Your cat’s primary job is to clean the engine particles that the engine omits. Catalytic converters are made out of ceramic. Thus, with added precious metals (another reason why Catalytic Converter care is critical). Naturally to filter the dirty particles from your engine. Thus reducing the pollutants from entering the atmosphere, this helps us to clean the environment and is part of the UK MOT test.

Your cat will only work correctly if the engine operates with the correct ratio of air to fuel. Naturally, this was your car servicing comes in. aged.
