Is a Cylinder Pressure of 6 Normal?

[DeCatherine]

A cylinder pressure of 6 is abnormal and indicates low cylinder pressure. Cylinder pressure standards vary by vehicle type: Japanese cars typically have a cylinder pressure of 1100 KPa, approximately 10 units of pressure; European and American cars range from 1200 KPa to 1300 KPa, about 12 to 13 units of pressure. Insufficient cylinder pressure can lead to the following consequences: 1. Decreased fuel efficiency, insufficient power, increased fuel consumption, and excessively high engine temperature; 2. Incomplete combustion leading to increased carbon deposits and severe engine vibration; 3. The mixture may leak into the crankcase, potentially causing explosions in severe cases; 4. Lubricating oil may enter the cylinder, resulting in oil burning; 5. Black smoke from the exhaust pipe and frequent engine stalling; 6. Reduced engine lifespan and premature vehicle failure.
