| 摘 要： | 从汽车使用的角度研究节油措施。运用发动机原理、汽车理论等基础知识，通过对汽车启动、起步过程中发动机温度、负荷对燃油消耗影响的分析，规范了汽车启动、起步操作，强调电控燃油喷射发动机的启动不能踩油门，否则会加大燃油消耗；将汽车起步过程的离合器踏板控制过程规范为快-慢-快3个阶段：指出车辆低档、低速行驶比发动机无负荷高速运转更能缩短发动机热车时间，节油效果更好；明确了商务车空载二档起步可以节油，而乘用车采用一档起步才能节油的机理。

| Abstract: | The measures of saving fuel have been studied in the angle of automobile use in this paper. Based on the basic knowledge of engine principle and automobile theory, the engine temperature and load influence on fuel consumption are analyzed during automobile starting and start-up, and the operations of starting and start-up are expounded. It is emphasized that the accelerator can not be stepped when EFI engine starts or the fuel consumption will rise. The clutch engagement for automobile start-up process can be controlled by the fast-low-fast speed. It is proposed that automobile driven at low gear and slow-speed should raise the engine temperature more quickly than the engine high-speed and free-load running, the fuel saving effect is also better. The mechanisms of saving fuel have been deciphered that business vehicle with no-load starts up at second gear and passenger car starts up at first gear. |
