Parts such as a cylinder body, a cylinder cover, a piston and the like which are in direct contact with high-temperature gas, if cooling is not timely or cooling is insufficient, parts can be accelerated to wear due to poor lubrication, and the power of an engine is reduced due to the reduction of the air charging quantity of a cylinder and abnormal combustion; however, excessive cooling may dilute the oil and affect lubrication, and may reduce thermal efficiency due to excessive heat dissipation. Therefore, the engine needs to operate in a more appropriate temperature range.
