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.
