4.10.12 Exhaust pipe
The exhaust pipe (Figures 4.43 and 4.45) is a pipe, which consists of several sections, in the intervals of which mufflers are installed.

The fact is that the combustion of the air-fuel mixture in the engine cylinder occurs so quickly that an almost explosion is obtained. And as soon as the exhaust valve opens, the sound starts propagating from the exhaust channel in the engine block head through the exhaust manifold into the exhaust pipe. In order to eliminate the rumble and noise, mufflers were invented, which, although they take away some of the engine's power, they do it exclusively with good intentions - so that the engine's operation is as invisible as possible.
