What is Cylinder Pressure?
1 Answers
Cylinder pressure refers to the magnitude of compression force when the piston reaches the top dead center at the end of the compression stroke. Insufficient cylinder pressure indicates reduced cylinder sealing, which will lead to decreased engine power and difficulty in starting. If individual cylinders have insufficient pressure, it will cause unstable engine operation. The typical cylinder pressure for gasoline engines ranges from 8 to 11 bar, while for diesel engines it ranges from 12 to 16 bar. Specific values should be referenced according to the manual. Cylinders can be categorized into two types: those performing reciprocating linear motion and those performing reciprocating oscillation. Cylinders performing reciprocating linear motion can be further divided into four types: single-acting cylinders, double-acting cylinders, diaphragm cylinders, and impact cylinders.
