经济车速与节油浅析

Elementary Analysis on Economical Vehicle Speed and Fuel-Saving

用经济车速行驶,是汽车节油途径之一。但目前存在着经济车速偏低、驾驶员对用经济车速操作的意义认识不够的问题。从试验对比可知,用经济车速驾驶汽车可节油5.7%～10%;正确使用节气门、合理选用变速档位器及在经济车速范围内的加速滑行等驾驶操作都可节油。

One of the fuel-saving approaches is driving a motor vehicle within an economical speed range. However there are two problems have to be solved, firstly the economical speed for conventional motor vehicles is too low, and secondly drivers often neglect driving vehicles within the economical speed range. Tests and comparisons show that motor vehicles running with economical speed can probably reduce fuel consumption by 5.7%～10. Correct driving operation, such as rationally controlling throttle, reasonably shifting transmission and making use of accelerating and coasting within the econmical speed range,helps to save fuel.
