一、经常保养空气滤清器,以减少进气阻力,注意不得用布或其他东西包裹空气滤清器。 二、不得将排气管的方向改变,以免增加排气阻力。 三、正确选择牵引负荷,不超载,不跑空车。 四、经常按规定调整气门间隙。如果因凸轮轴磨损而引起配气相位角减小,可适当减小气门隙使之不小于0.2毫米,以弥补配气相位角的减小;凸轮轴严重磨损时应更换。 五、正确调整机车各传动部位的配合间隙,以减少传动部分的动力消 First, regular maintenance of air filters to reduce the intake resistance, be careful not to use cloth or other things wrapped air filter. Second, the direction of the exhaust pipe may not be changed, so as not to increase the exhaust resistance. Third, the correct choice of traction load, not overloaded, do not run empty car. Fourth, often adjust the valve clearance as required. If the camshaft wear caused by the gas phase angle decreases, the valve can be properly reduced so that the gap is not less than 0.2 mm, to compensate for the gas phase angle decreases; serious wear camshaft should be replaced. Fifth, the correct adjustment locomotive with the transmission parts of the gap, in order to reduce power transmission part of the consumer
