发动机是汽车的动力核心,是一个能量转换机构,通过燃料在密封气缸内燃烧气体膨胀,推动活塞作功,转变我机械能。机械性能的好坏直接影响到运输成本和生产效率,分析发动机早期损坏的原因,针对不同的状况找出对应的预防措施,对于提高汽车的使用经济性有十分重要的意义。
The engine is the power core of an automobile. It is an energy conversion mechanism that expands the combustion gas in the sealed cylinder by the fuel to promote the work of the piston and transform my mechanical energy. The mechanical performance directly affects the transportation cost and production efficiency. Analyzing the causes of early engine damage and finding the corresponding preventive measures according to different conditions are of great significance for improving the economical efficiency of vehicles.
