    摘要： The present invention relates to a fuel injection method of an internal combustion engine having higher combustion stability which can direct a part of concentrated fuel spray (203) toward an ignition plug (403) according to a fuel injection atmosphere, a fuel injection valve (401) thereof, and an internal combustion engine. The present invention provides a fuel injection method of an internal combustion engine for injecting fuel so as to generate a part of high spray concentration and a part of low spray concentration on the cross section of spray (203) by giving swirling force to fuel from an injection hole (101) at the front end of a fuel injection valve (401), comprising the step of setting a reference indicating the position of a axis of the fuel injection valve (401) indicating the injection direction of the part of high spray concentration in the rotational direction when fuel is injected into an atmosphere under the atmospheric pressure.

    摘要： A fuel pump 20 for a direct injection internal combustion engine 22 having a body 24 with a valve seat 54. The valve 50 includes a valve head 52 and the valve 50 is movably mounted to the body 24 between an open position and a closed position. In its open position, the valve head 52 is spaced from the valve seat 54 while in its closed position, the valve head 52 abuts against the valve seat 54 and closes the valve 50. An electric coil 56 upon energization moves the valve 50 to an open position and, conversely, upon deenergization allows the valve 50 to move to a closed position. A control circuit 62 controls the energization of the coil 56 to reduce the pump noise during operation of the engine 22, especially at low speeds.
