Abstract
The invention discloses an electrically controlled air discharging device for an oil way of a diesel engine. The electrically controlled air discharging device for the oil way of the diesel engine comprises an oil supply pump system, an oil inlet bolt and an oil return bolt, wherein the oil inlet bolt and the oil return bolt are mounted on the oil supply pump system; one end of an oil inlet pipe is connected to an oil inlet of the oil inlet bolt, and the other end of the oil inlet pipe is arranged at the bottom of a fuel tank; a coarse filter with an electric pump, an oil delivery pump and a fine filter are sequentially mounted on the oil inlet pipe; an overflow device and an air discharging device are arranged on the oil return bolt; when oil pressure is over-high, the overflow device overflows. A switch is pressed to turn on the coarse filter with the electric pump and an oil return electromagnetic valve simultaneously by virtue of a control wire harness. Fuel inside the fuel tank can be quickly sucked into the oil delivery pump through the oil inlet pipe by virtue of the coarse filter with the electric pump, and enters the oil supply pump system from the oil inlet bolt by virtue of the fine filter. Meanwhile, air inside the oil way can return to an oil returning pipe together with the fuel from the air discharging device on the oil return bolt by virtue of the electromagnetic valve, and finally returns into the fuel tank. Then, air resistance does not exist in the oil way and an oil pump, so that the fuel can be smoothly supplied to a fuel injection system.
