    摘要： A fuel injection system comprising a fuel injection pump, at least one fuel injection nozzle connected thereto, and a control device for varying the rate of injection of the system according to varying engine parameters. The control device has a variable volume chamber, the volume of which is varied by a piston located by a piezoelectric actuator. The variable volume chamber and a pumping chamber of the pump is intermittently connected by a passage which is specifically designed in such a manner that the fluid communication between the chambers, during the delivery stroke of a pump plunger, is provided only for an initial stage of the delivery stroke. A rate of injection is controlled in the initial stage to perform a pilot injection. In the subsequent stage, in which there is no need for rate-of-injection control, the variable volume chamber is isolated from the pumping chamber in order to relieve the piezoelectric actuator from an excessively high fuel pressure that would cause degradation of the piezoelectric elements.

    摘要： A fuel vapor purging system includes a container in which a set of divided chambers are formed by partition walls. Absorbent is disposed in the divided chambers. The divided chambers are sequentially connected to form a zigzag passage. Fuel vapor can enter the container from a fuel tank via a vapor line connecting the fuel tank and the container. In the container, an end of the vapor line faces the divided chamber which occupies an end of the set of the divided chambers. In the container, the fuel vapor is absorbed by the absorbent. Air can escape from the container via an opening in the container. The fuel vapor can be separated from the absorbent. The separated fuel vapor can be drawn into a suitable drawing device such as an engine air induction device via a purge line connecting the container and the drawing device. Fresh air can flow into the container via an air inlet provided on the container. Among the divided chambers, at least the divided chamber which occupies the end of the set of the divided chambers has a cross-sectional area equal to or smaller than 40 cm.sup.2.

    摘要： In a fuel injection apparatus for an internal combustion engine, the fuel injection is ended by a spill mechanism provided in a spill passage communicating with a pumping chamber. A piston opening and closing the spill passage is a free piston, and a solenoid valve to open and close a cylinder in which the free piston is disposed, is also provided. As the solenoid valve closes the cylinder, the free piston closes the spill passage, thus enabling the fuel feed to the fuel injection valve. When the solenoid valve opens the cylinder, the free piston opens the spill passage. Thus, the fuel flows through the spill passage to the fuel reservoir.

    摘要翻译： 在用于内燃机的燃料喷射装置中，燃料喷射由设置在与泵送室连通的溢流通道中的溢流机构结束。 打开和关闭溢流通道的活塞是自由活塞，并且还提供了用于打开和关闭其中设置有自由活塞的气缸的电磁阀。 当电磁阀关闭气缸时，自由活塞关闭溢流通道，从而使得燃料供给到燃料喷射阀。 当电磁阀打开气缸时，自由活塞打开溢流通道。 因此，燃料流过溢流通道进入燃料储存器。
