Experimental Investigation to Fuel Consumption Characteristics of Light-duty Passenger Vehicle under Sliding Condition
Technical level of driving behavior has run as high as 20％impact on vehicle’s fuel consumption,so choosing proper operation mode is one effective way to improve the vehicle’S running fuel economy．Vehicle sliding on leveI road is often used by driver,and analyzing vehicle’s fuel consumption characteristics during sliding condition has practical significance on realizing the reasonable driving and lowering fuel consumption．Taking some light-duty diesel passenger vehicle as experimental object，this paper discussed the variation discipline and curves involving sliding speed,sliding time and fuel consumption rate based on various sliding tests, especially analyzed the fuel consumption difference of sliding in neutral and sliding in different gears．Finally．following conclusions are achieved：the average fuel consumption rate while vehicle sliding in different gears iS similar．which is about to 1/50 of sliding in neutral’.while sliding,the vehicle’s fuel consumption rate basically maintains at a low level．But once the sliding speed decreases too low．the fuel consumption rate increases dramatically．Therefore,aiming at lowing fuel consumption and reducing emission discharge,vehicle sliding in gear should have priority to sliding in neutral and choosing a reasonable sliding speed range is important for reducing vehicle’s running fuel consumption and exhaust emission．
