有的东方红—75(54)拖拉机驾驶员在起动车时,不是将减压手柄放到“工作”位置后再给发动机供油.而是在起动车前就将油门手柄放到了供油位置。显然这种操作是错误的,因为在减压状态下供给发动机的柴油不能燃烧,产生如下危害: 1.发动机起动时(着火前)不需供油,而如上操作使一定量的柴油进入气缸,浪费了燃料,提高了作业成本。 Some Dongfanghong -75 (54) tractor driver in the starter car, not the decompression handle into the “work ” position and then to the engine oil.But in the starting vehicle before the throttle handle into the Oil position. Obviously, this operation is wrong because the diesel oil supplied to the engine under a reduced pressure can not be burned, resulting in the following hazards: 1. No oil is required at the start of the engine (before the fire), and a certain amount of diesel oil enters the cylinder as above, Wasting fuel and raising operating costs.
