摘要： Fuel injection apparatus comprising a solenoid coil (40); an armature (41) coupled with a valve element (34) operable to open and close a fuel valve (32) when the solenoid coil (40) is selectively energized and de-energised. The valve element (34) is biased to the closed position by a biasing device (42). Magnetic force from the energized solenoid coil moves the armature (41) and valve element (34) to open the valve to an opening position to deliver fuel reached when a controller (170) calculates opening forces balance closing forces. Such opening position control is used to control fuel flow rate to a gas fuelled engine (20) and/or reduce noise vibration harshness in varied engine types. Balance of forces control, on closing of the valve, reduces or avoids impact of the valve element (34) with a physical stop (106), thus reducing engine noise, and can be used in fuel metering.

摘要： A fuel injection valve device is capable of thinning a nozzle hole plate and improving fuel spray characteristics by a construction for reducing stress concentration that occurs at the weld part of the nozzle hole plate. The fuel injection valve device includes: a nozzle having a fuel passage inside and in which a valve seat is formed at an end; a needle valve for opening and closing the fuel passage by coming in contact with and separating from the valve seat; and an nozzle hole plate that is disposed at the tip of the nozzle and injects a fuel in the fuel passage at the time of opening the needle valve. The nozzle hole plate and the nozzle are fixed by welding in a state of forming an even gap between them.

The first groove is provided so that the needle valve is rotated by flow of the fuel in the first groove caused by reciprocating motion of the needle valve, and the upper and lower ends of the first groove are opened to the outside so that a part of fuel can be introduced in to the groove. The second grooves are twisted or tilted in the same direction as the rotating direction of the needle valve and are cut along the circumferential direction of the nozzle tip. The second grooves have an edge part for scraping off solid matters in the fuel into the second grooves in cooperation with of the tip seat surface of the needle valve affected by the rotation of the needle valve.
