Features and requirements of intake and exhaust system of Komatsu excavator:

(1) the function of the power intake and exhaust system is to distribute the combustible mixture or pure air into every cylinder as much as possible and evenly. After the combustion of the mixture, the exhaust gas of each cylinder is collected and the noise of the exhaust muffler is eliminated and the air is discharged.

When the diesel engine works, the dust impurity in the air will be inhaled in the cylinder with the air together, and mixed with the lubricating oil to form a destructive abrasive particle, which causes the cylinder, the piston group and the valve mechanism to be seriously worn, so that the service life of the engine is greatly shortened. Therefore, diesel engines must never be allowed to work without air filters.

The exhaust noise control system of diesel engine must meet the following requirements.

A, check the exhaust backpressure should not exceed the limit of the engine performance parameters. In the design, we should try to avoid small diameter and sharp turning.

B, without increasing the backpressure of exhaust, the exhaust noise can be reduced, so that the noise level of the vehicle can meet the national environmental regulations.

C and exhaust muffler system can not cause excessive torque to turbocharger due to factors such as weight, inertia, relative movement of parts or thermal deformation.
