How much is the engine cylinder pressure within the normal range?

The cylinder pressure of automobile engine is about 1000KPA.

The working condition of the engine first depends on the cylinder pressure of the engine. General gasoline engine 1000KPA, diesel engine 2000KPA. The cylinder pressure of most EFI engines is 1200~ 1400kPa, and the cylinder pressure of a few high compression ratio engines is above 1700kPa.

Pneumatic system and electric system are not mutually exclusive. Instead, just ask different questions. The advantages of pneumatic drive are obvious. When faced with harsh environmental conditions such as dust, grease, water or detergent, the pneumatic driver is more adaptable to the harsh environment and very durable. The pneumatic driver is easy to install, can provide typical grasping function, and is cheap and easy to operate.

When the force increases rapidly and accurate positioning is needed, the electric drive with servo motor has advantages. For applications that require accurate, synchronous operation, adjustable and specified positioning programming, electric drive is the best choice, and the electric drive system composed of servo or stepping motor and closed-loop positioning controller can supplement the shortcomings of pneumatic system.
