exhaust system of the car is very important.Its main purpose - ventilation of the cylinder.The exhaust gases in the exhaust stroke to reach the exhaust manifold, followed by the reception tube.Then on the way "smoke" was found a pair of resonators, and ends with a "journey" to the atmosphere through the muffler.Let's take a moment to its design.In fact, a silencer - a tin can with a variety of partitions inside.They form a sort of labyrinth, passing through which the gases are cooled, lose speed and more reduced in volume.
Often, manufacturers do not expect to exhaust system at peak performance, while tuners have to produce some of the details, for example, exhaust pipes, with their own hands.What are the advantages of cottage industry to factory?Let's consider them.The very first reason for which the silencer is to make their own hands - this increase in its volume.In this case, the gas pressure at the outlet will drop significantly, which will result in a marked reduction in noise operation of the vehicle as a whole.Furthermore, the pressure drop in the system.Then the exhaust gases leaving the cylinders easier consequently slightly increases the performance of the power unit.
The second reason for which the silencer is to make their own hands - this is the material of manufacture.As a rule, the main cause of failure of an exhaust system - is its burn-out, because the temperature of the work is very large.Conclusion: the need to select the material of greater thickness.This can be a tube or sheet metal.Naturally, we must not forget about the weight of the product.Such a homemade silencer can last much longer than regular.In addition, you can change the geometry and partitions inside, which also have a positive impact on overall system performance and noise emissions.
learn how to make a silencer, you can find a variety of instructions.Each of them is almost universal.It is not surprising, because the muffler can be made with their own hands for the same model and brand, as he is fit to a dozen of these.Here, in principle, differentiation only concern the working volume of the engine, because too little muffler simply will not cope with the volume of gas passing through it.
In addition, it will be too noisy operation of the engine.It follows that the reasons to do with their hands silencer there is quite a lot.But do not think that this is a win-win, so you never know the problems with the exhaust system and the engine just a few times and pick-up will not be at the same time to make a sound.Everything has its disadvantages.
example, inspection.With the silencer may be problems with the certification.If the operation noise standards are not exceeded, then everything will be okay.On the toxicity of exhaust design is absolutely not affected.Particular attention should be paid to mount: they must be flexible as well as very "thumbs" should not touch the bottom of the car.Also, do not forget about fire safety, to ensure that it will be enough asbestos sheet sandwiched between silencer and the bottom.
