摘要： Fuel for a working cylinder chamber (8) of an internal combustion engine is drawn through an atomising nozzle (39) from an accumulator (30). Fuel is supplied by a low pressure source (12) through a variable constriction (16) linked to the throttle (4) and through a selenoid valve which is pulsed at a frequency proportional to engine speed.

摘要： A needle is forced to open an injection hole by reducing a pressure of fuel in an injection control chamber to thereby inject fuel stored in a fuel storage, while the needle is forced to close the injection hole by increasing the pressure of fuel in the injection control chamber to thereby terminate injection of fuel from the injection hole. In a valve-closing stroke of the needle to close the injection hole, fuel pressure is supplied from a common accumulator to the fuel storage and the injection control chamber in such a manner that the pressure to supply fuel to the fuel storage is lower than that to supply fuel to the injection control chamber. In this way, a force acting on the needle toward the injection hole side can be increased in the valve-closing stroke, to thereby accelerate a valve-closing speed of the needle.
摘要翻译：通过降低喷射控制室中的燃料的压力来迫使针打开喷射孔，从而喷射储存在燃料储存器中的燃料，同时通过增加喷射控制中的燃料的压力迫使针闭合喷射孔从而终止从喷射孔喷射燃料。在关闭喷射孔的针的阀关闭行程中，燃料压力从公共蓄积器供应到燃料储存器和喷射控制室，使得向燃料储存器供应燃料的压力低于燃料储存器将燃料供应到喷射控制室。以这种方式，在关阀行程中，可以增加朝向喷孔侧作用在针上的力，从而加速针的关阀速度。
