What happens when the engine cylinder pressure is low?

[DelColton]

Low engine cylinder pressure can result in difficulties starting the engine, insufficient power, shaking during operation, and failure to meet exhaust emission standards. Causes of insufficient engine cylinder pressure include: 1. Severe wear of piston rings, leading to reduced sealing effectiveness; 2. Abnormal wear such as scratches or unevenness on the cylinder walls; 3. Poor sealing of valve seats or spark plug seats; 4. Damage to the cylinder gasket. The car engine is the device that provides power to the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.
