Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a duel fuel diesel engine combining gas fuel, achieving lower exhaust gas pollution by preventing the occurrence of unburnt gas or black smoke. SOLUTION: The duel fuel diesel engine comprises a first fuel supply system F1 for supplying a liquid fuel and a second fuel supply system F2 for supplying a gas fuel. The second fuel supply system F2 consists of a gas supply source 17, a pressure controller 19 for controlling the supply pressure of the gas and a gas injector 20 for injecting and supplying the gas fuel to an intake port 30. The gas injector 20 is arranged on the outer face of the engine, with its injection passage 21 having an exit 31 facing to the intake port 30. In a second intake stroke S2 after closing an exhaust valve 11, the gas fuel is injected and supplied to the intake port 30 by the gas injector 20. COPYRIGHT: (C)2003,JPO
