摘要： A fuel-injecting apparatus supplies fuel to an internal combustion engine in a timing and at a rate adapted for its operation. The internal combustion engine includes a lubricant trap provided at the bottom of the internal combustion engine to collect lubricant for lubricating the internal combustion engine and a fuel pump for supplying the lubricant held in the lubricant trap to a fuel-injection device. In the fuel-injecting apparatus the intermediate part of a passage through which lubricant is delivered to a fuel-injection timing control device is branched off, and the branched division of the lubricant passage is made to communicate with the lubricated section of the fuel pump.

摘要： A fuel injection timing control system is provided wherein a fluid actuator having a fluid chamber containing therein a movable wall member and the amount of pressure medium in the fluid chamber are controlled by electromagnetically operated control valve means to cause the actuator to operate an element for controlling the fuel injection timing of a fuel injection pump. In the control system of this invention, a control voltage is produced from at least a speed signal corresponding to the rotational speed of an engine and a fuel injection quantity signal corresponding to the amount of fuel injected into the engine from a fuel injection pump, and this control voltage is compared with a injection timing voltage corresponding to the fuel injection timing of the fuel injection pump to produce a deviation signal which is used to actuate the electromagnetically operated control valve means so as to automatically control the fuel injection timing of the injection pump and thereby to obtain the optimum injection timing that suits the varying operating conditions of the engine.
