LIQUEFIED GAS-DELIVERING DEVICE FOR DIESEL ENGINE

摘要

An aspirator (7) is provided at a lower position than an oil sump chamber (11) and an over flow fuel pipe (81), and therefore DME fuel remaining in the oil sump chamber (11) and the over flow fuel pipe (81) can be efficiently recovered to a fuel tank (4) by force that is the sum of aspiration force occurring at an aspiration opening (7c) of the aspirator (7) and gravity. A solenoid valve (74) for opening and closing a gas-phase pressure send-out pipe is provided at a higher position that the oil sump chamber (11), and therefore DME fuel in a liquid state remaining in the oil sump chamber (11) and the over flow fuel pipe (81) is forcibly sent by pressure to the aspiration opening (7c) of the aspirator (7) by force that is the sum of a pressure of a gas phase (4b) in the fuel tank (4) and gravity. This way, the time to recover DME fuel in an injection system to the fuel tank after the stop of a diesel engine is shortened.
