METHOD FOR STARTING DIMETHYL ETHER FUEL-USING ENGINE, AND DIMETHYL ETHER FUEL-USING ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a method for starting a dimethyl ether fuel-using engine, the method capable of sensing ignition caused by a leaked fuel before starting fuel injection in the dimethyl ether fuel-using engine so that in the case ignition caused by a leaked fuel is sensed, start of the engine is stopped and simultaneously with the engine stoppage an alert is emitted to the driver, and to provide a dimethyl ether fuel-using engine.SOLUTION: The method includes: sensing a presence of ignition caused by a fuel leaked into the cylinder before the start of the fuel injection into a cylinder of the engine 1 at the start of fuel injection in a dimethyl ether fuel-using engine; stopping the start of the engine 1 when the ignition of the leaked fuel is sensed; and sensing the presence of the ignition caused by the leaked fuel, by sensing fluctuation of the engine speed Ne with an engine rotation sensor at starting cranking with a starter 38.
