摘要： The invention is intended to provide a fuel injection device capable of reducing NOx in exhaust gases while satisfactorily maintaining the fuel consumption rate, and also provide a diesel engine having the same. This fuel injection device comprises a pressure accumulator for accumulating pressure-increased fuel, a fuel injection valve for injecting fuel by being opened in response to the feeding of fuel from the pressure accumulator, a feed passageway for feeding fuel to the fuel injection valve from the pressure accumulator, and two magnetic valves connected in parallel to the feed passageway and adapted to individually make or break the feeding of fuel to the fuel injection valve. And one magnetic valve has its fuel flow rate during opening thereof set at a value lower than that for the other magnetic valve during opening thereof. In feeding fuel to the fuel injection valve, the magnetic valve is first opened and then the other magnetic valve is opened.

摘要： An object is to provide a precombustion-chamber fuel supply device for a precombustion-chamber gas engine having high reliability and low operation cost by reducing outflow of fuel gas to the precombustion chamber in the exhaust stroke and dispersion of the amount of fuel gas supplied to the cylinders, which makes it possible to cut fuel consumption and to achieve stable combustion. A gas internal combustion engine of a Miller-cycle type includes: a main chamber 60 defined between a piston and a cylinder head 1; a precombustion chamber 4 which communicates with the main chamber 60 via a nozzle 3 and in which fuel gas is combusted by a spark plug 10; a gas supply channel to precombustion chamber 14 for supplying the fuel gas to the precombustion chamber 4; and a check valve 6 disposed in the gas supply channel to precombustion chamber 14 and configured to open due to a pressure decrease in the precombustion chamber 4 at a BDC of an intake stroke of a Miller cycle in which the piston closes an intake valve before the BDC of the intake stroke so as to allow supply of the fuel gas to the precombustion chamber 4.
