Kind Code:
A1
Abstract:
A rapid activation method utilized in an electrically controlled common rail engine. The method comprises: arranging, between an oil outlet of an oil transfer pump (3) and an oil inlet of a fuel pump (5) in the electrically controlled common rail engine, a gas discharging device (6); and communicating an output port of the gas discharging device (6) with a fuel tank (1) via a pipe to discharge a gas present in fuel during a normal system operation. By arranging the gas discharging device (6) at an oil feeding port (41) of a fine filter (4), the method can be utilized to discharge, via the gas discharging device (6) to the outside, air in the fine filter (4), thereby implementing active gas discharging, and effectively increasing activation performance of the engine.
