目前柴油发动机较普遍使用涡轮增压装置,目的是增加气缸进气量,使燃料充分燃烧,提高其动力性能和经济性能。而这种涡轮增压器的润滑方式是靠主油泵供给实现压力润滑的,一些驾驶操作人员不注意其工作原理,在停车熄火时故意加大油门,然后拉动闭车手柄。这样一来,涡轮增压器在惯性力作用下每分钟可达几万转,由于主机停机油泵不能实现供油润滑,而高速旋转的增压器还要持续一定时间才能慢慢的停下来,这样将会使增压器加速磨损,减少其使用寿命。所以提醒广大驾驶
At present, diesel engines are more commonly used turbocharger devices, the purpose is to increase the cylinder intake, the fuel combustion, improve its dynamic performance and economic performance. The turbocharger lubrication is based on the main oil pump to provide pressure lubrication, and some driving operators do not pay attention to its working principle, in the parking stall intentionally increase the throttle, and then pull the closing handle. As a result, the turbocharger in inertia force up to tens of thousands of revolutions per minute, due to the host shutdown pump can not achieve oil lubrication, and high-speed rotation of the turbocharger also continue for some time to slowly stop, This will accelerate the supercharger wear and tear, reducing its service life. So remind the majority of driving
