1．合理使用(1)严防发动机启动后立刻加速正常情况下,会有一定量的润滑油存留在轴承中,可供发动机启动和怠速时润滑用,但是,若发动机转速超过1 000 r／min时,就需要有润滑油流润滑,发动机启动后至少需要15～30 s才能在润滑系统中形成油压和油流,如果在节气门大开下启动,2 s内便可达到最高转速,这就是说轴承将在十多秒内处于无润滑的状态下,且以较高速度运转,因此很容易引起轴承损伤。为此,应切记必须在节气门处 1. Proper use (1) Prevent the engine immediately after the start of acceleration Under normal circumstances, there will be a certain amount of oil remain in the bearings for engine start and idle lubrication, but if the engine speed exceeds 1 000 r / min Need to have a lubricant flow lubrication, the engine starts at least 15 ~ 30 s to form oil pressure and oil flow in the lubrication system, if the throttle open under the start, 2 s can reach the maximum speed, which means that the bearing Will be in more than ten seconds without lubrication, and at higher speeds, it is easy to cause bearing damage. For this reason, it should be remembered that it must be at the throttle
