摘要： In a gas fuel engine, a first air-fuel mixture having a local excess air factor λ not less than 2 is combusted (a first combustion). When a target torque is not sufficiently obtained by the first combustion, a fuel is directly injected into a combustion chamber to form a second air-fuel mixture having a local excess air factor λ less than 1.1, so that a second combustion is performed. The combustion of the air-fuel mixture is switched from the first combustion to the second combustion in one combustion stroke.

摘要： The angle of fuel spray at the time of pre-injection is set to a wider angle of spray and the angle of fuel spray at the time of main injection is set to a narrower angle of spray. The pre-injection timing is set so that when fuel spray after the pre-injection is diffused in a cylinder and stratified, the stratified fuel spray is ignited by a rise in the pressure in the cylinder in association with movement of a piston from the bottom dead center to the top dead center. The main injection timing is set so that when the spray stratified by the pre-injection is burned, the fuel spray injected by the main injection passes through the combustion zone while being ignited in the combustion zone, reaches a combustion chamber of the piston, and is burned in the combustion chamber.

摘要： In a fuel injection nozzle, a nozzle body is provided inside with a guide hole having a second guide portion (cylindrical hole) for slidably holding a guide shaft of a needle and a seat surface axially below the second guide portion, with first injection bores opened to the seat surface and with second injection bores opened to an inner circumference of the second portion. The needle is provided at an end thereof with a circular seat contact coming in contact with the seat surface axially above the first injection bores and inside the guide shaft with a fuel passage through which fuel is supplied to a position axially above the seat contact. With the construction mentioned above, as the second guide portion is formed axially above the sack chamber and inner diameter thereof is larger than that of the sack chamber, the second guide portion is more easily formed at lower cost.

摘要： A fuel injection valve has a sac chamber filled with high-pressure gaseous fuel, an injection hole communicated with the sac chamber, and a nozzle needle that slidably moves to allow and interrupt a supply of the high-pressure gaseous fuel into the sac chamber. The fuel injection valve performs an injection of the high-pressure gaseous fuel directly into a combustion chamber of the internal combustion engine in accordance with a movement of the nozzle needle. The injection hole has an outlet portion with a divergently formed inner surface as coming toward an outlet end of the injection hole. The driving portion controls the movement of the nozzle needle to change a sac chamber pressure of the high-pressure gaseous fuel in the sac chamber so as to switch a jet flow speed of the high-pressure gaseous fuel injected through the injection hole between a subsonic speed and a supersonic speed.
