What is the normal cylinder pressure for a car?

[StKennedy]

Car cylinder pressure is normal between 1100 and 1300 kPa. The reasons for insufficient engine cylinder pressure are: 1. Insufficient cylinder lubrication causing cylinder scoring, leading to excessive wear on the cylinder walls; 2. Poor or damaged cylinder gasket sealing, resulting in insufficient airtightness between the cylinder block and cylinder head; 3. Excessive flatness of the two contact surfaces between the cylinder head and cylinder block, causing poor cylinder sealing; 4. Intake and exhaust valves not closing tightly; 5. Car cooling system failure leading to insufficient engine cooling. The solutions for insufficient engine cylinder pressure are: 1. Replace piston rings or cylinder liners; 2. Replace the cylinder gasket and tighten the screws to the specified torque; 3. Check if the water passages are clear, pay attention to adding coolant, and promptly replace and eliminate any leaking areas.
