Introduction to power
The liter power is a general evaluation of the utilization of the cylinder working volume from the perspective of the effective power of the engine. The higher the value of the liter power, the higher the degree of engine reinforcement, and the smaller the engine size that emits a certain effective power. Therefore, continuously increasing the Pme (average effective pressure) and n (speed) levels to obtain a more intensive, lighter and more compact engine has always been the goal of the internal combustion engine workers, so the power is to evaluate an engine. One of the important indicators of machine dynamic performance and degree of reinforcement.
