检查轮胎气压气压过高或不足,都会增加行驶阻力,使油耗升高。紧固螺钉据测定,如发动机支架和变速箱之间的螺钉松动,损耗就会增加。清洗空气滤清器若空气滤清器横截面堵塞三分之一,耗油率提高1.7%。调整供油提前角如195柴油机的供油提前角为16～20,用增、减喷油泵与齿轮室盖之间的调整垫片来保证;提前角偏小,柴油燃 Check the tire pressure pressure is too high or too low, will increase the driving resistance, so that fuel consumption. Tightening screw It is determined that if the screw between the engine mount and the gearbox is loose, the loss will increase. Cleaning the air cleaner If the air filter is blocked by a third of its cross section, the fuel consumption rate is increased by 1.7%. Adjust the fuel supply advance angle, such as 195 diesel engine oil supply advance angle of 16 to 20, with increasing, reducing fuel pump and gear chamber cover between the gasket to ensure that the advance angle is small, diesel fuel
