What are the symptoms of excessive engine cylinder pressure?

[OVanessa]

Excessive cylinder pressure in a car can cause engine knocking and difficulty in starting. Here is an introduction to the cylinder: 1. Cylinder pressure: Generally, it depends on the valve. If the valve cannot withstand it, the cylinder's own pressure is useless no matter how high it is. The normal cylinder pressure is 0.3-0.8 MPa. The pressure a cylinder can withstand mainly depends on three parameters: the inner diameter of the cylinder, the diameter of the piston rod, and the working pressure applied. 2. Introduction to the cylinder: It is an important component of pneumatic components. Pneumatic components include air source processing components, pneumatic control components, pneumatic actuators, and pneumatic auxiliary components.
