Abstract: A rapid activation method of an electrically controlled common ail engine. The method includes: arranging, between an oil outlet of a fuel transfer pump and an oil inlet of a fuel injection pump in the electrically controlled common rail engine, a gas discharging device; and communicating an outlet of the gas discharging device with a fuel tank via a pipe to discharge a gas present in fuel during a normal system operation. By arranging the gas discharging device at an oil feeding port of a fine filter, the method can be utilized to discharge, via the gas discharging device to the outside, air in the fine filter, thereby implementing active gas discharging, and effectively increasing activation performance of the engine.
