Exhaust pipe: varieties, purpose, malfunctions

Every car is equipped with both intake and exhaust systems. Many may think that the exhaust pipe is just an extension of the exhaust manifold, which serves solely to release exhaust gases without any extraneous benefit to the engine. To some extent this statement is true, but its uselessness can be argued. First of all, it is worth saying that exhaust systems are quite complex and are the result of lengthy calculations, which include such quantities as diameter, shape, length, as well as the volume of the resonator and muffler.

Exhaust pipes can be made from various materials: heat-resistant, lightweight, stainless, chrome, and so on. It all depends on the temperature conditions under which they will work, on how visible they will be from the outside. Weight also plays a big role, as exhaust system replacement is often done to lighten the car to make it more dynamic.

Now about the diameter. The exhaust pipe of increased diameter has an increased capacity, therefore, engine ventilation is improved. In addition, the pressure in the system is significantly reduced, andThis means that the noise of the gases at the outlet is also reduced. Naturally, every car owner will not mind improving this indicator of his car.

Exhaust pipes are often made of stainless steel. The fact is that they have an elevated melting point, and also have low weight and ideal anti-corrosion properties. Plus, stainless steel is easier to machine because it is softer than other types of metal.

If the engine has a large volume, the exhaust pipe can be divided into two streams. There are cases when the exhaust pipe leaves the unit itself alone, but the muffler has the width of the entire car, so two pipes come out of it.

More often you can find an exhaust system in which for every 3 or 4 cylinders an exhaust manifold is attached, that is, the exhaust pipe is simply duplicated. This design is widely used in V-shaped engines, since they are not difficult to branch, and their volume, as a rule, is three liters or more. In small engines, such a system is not used, since this only increases the cost of the car without visible improvements, such refinement becomes solely the initiative of the owner.

A fairly common problem with an exhaust system is its deformation. Naturally, in our country such a situation is not uncommon, since the quality of our roads is known to everyone. In such situations, car owners ask themselves: “But it’s not harmfulIs it for the engine? Yes, it's not critical. This means that the operation of the car can continue in the same mode as it was carried out, but it is worth replacing the damaged section of the system as soon as possible. To do this, all systems are made collapsible so that this procedure can be carried out easier and without replacing the entire section.

Many car owners believe that the exhaust system does not require any maintenance. This is partly true, but there are some nuances. First of all, you need to monitor its external state, so that the situation described above does not arise. You should also keep in mind while driving that the exhaust pipe is the lowest point of the car. In the event of a burnout or other damage to the pipe, it is not worth pulling with a replacement, as the level of external noise rises sharply, and the ride becomes uncomfortable.
