DME FUEL FEED DEVICE OF DIESEL ENGINE

摘要

A three-way valve (71) is closed and two-way valve (72) is opened during non-injection state, to supply dimethyl ether (DME) fuel from feed pump (5) into aspirator (7). The solenoid valve (75) is opened to connect the fuel tank (4) with inlet of oil reservoir through pressure supply pipe (73) and to force-feed liquid state DME fuel in oil reservoir and overflow fuel pipes (8,9) to suction port by high pressure of gaseous phase.
