一台TY220型推土机在燃油耗尽后重新加注燃油,驾驶员图省事,不进行人工排气,通过启动马达带动柴油机转动来进行排气。这样操作危害极大,不仅使蓄电池耗电量增加,而且很容易损伤PT喷油器。PT泵供应低压燃油,PT喷油器控制进入汽缸燃油的油量和压力,通常压力高达70—140 MPa,因此需要及时润滑、冷却配合偶件。进入PT喷油
A TY220 bulldozer refueling after depleted fuel, the driver plans save trouble, no artificial exhaust, by starting the motor to drive the diesel engine to exhaust. This operation is extremely harmful, not only to increase the battery power consumption, but also easy to damage the PT injector. The PT pump supplies low-pressure fuel. The PT injector controls the amount and pressure of the fuel entering the cylinder, typically up to 70-140 MPa, thus requiring timely lubrication and cooling for mating parts. Into PT injection
