Characteristics of the engine:
If the load, speed and road condition of the automobile engine change frequently, the engine as the power source must adapt to the driving needs of the automobile and work under the condition of the load and speed changing frequently. Due to the diversity of engine operating conditions and performance indicators, there are many types of engine characteristics. Among them, there are speed characteristics, load characteristics and universal characteristics closely related to the automobile.
