What is the normal cylinder pressure?

[OZane]

Normal cylinder pressure varies depending on the vehicle series: 1. Japanese cars are around 1100kpa; 2. European and American cars are around 1200 to 1300kpa. Insufficient cylinder pressure can lead to excessive carbon deposits, severe engine shaking, increased fuel consumption, and even engine overheating, making it difficult to start the car. Causes of insufficient cylinder pressure include: 1. Piston ring misalignment, excessive wear, and insufficient cylinder lubrication; 2. Poor sealing or damage to the cylinder gasket; 3. Excessive flatness of the two contact surfaces between the cylinder head and cylinder block, resulting in poor sealing; 4. Poor sealing of intake and exhaust valves; 5. Malfunction in the car's cooling system leading to insufficient engine heat dissipation.
