The exhaust system is designed to release exhaust gases into the atmosphere
The system consists of two exhaust manifolds 9, two exhaust pipes 7 and 8, a flexible metal hose 5, and a muffler 1.
Each exhaust manifold serves a bank of cylinders and is attached to the cylinder block with three bolts.
The manifolds are connected to the cylinder heads by pipes.
The detachable connection of the manifold - pipe - head allows you to compensate for thermal deformations that occur during engine operation.
The intake pipes are united by a tee: and connected to the muffler by a flexible metal sleeve, which compensates for assembly errors and temperature deformations of system parts.
A damper for the auxiliary engine brake system is installed in each exhaust pipe.
Exhaust noise silencer (Fig. 2) is active-reactive, non-separable design.
An active muffler operates on the principle of converting sound energy into heat, which is carried out by installing perforated partitions in the path of gases, in the holes of which the flow of lawn is crushed and the pulsation is damped.
The reactive muffler uses the principle of acoustic sound filtration. This muffler is a series of acoustic chambers connected in series
On the exhaust pipe of the muffler of the KamAZ-55111 dump truck, an exhaust pipe 2 is installed, designed to heat the platform with exhaust gases in the cold season
When operating a dump truck in the cold season, to heat the platform, remove the plug from the vertical muffler pipe and install it between the tee pipe and the exhaust pipe.
In the warm season, install a plug on the vertical pipe of the muffler, removing it from the tee branch
