摘要： In a Diesel engine with a Bosch-type fuel pump or the like having a control lever which determines the fuel injection quantity, idling speed is controlled by a movable stopper which abuts the control lever to place a lower limit on fuel injection quantity during idling. A control unit derives a target idling speed value according to engine temperature, electrical load, etc. and controls the pneumatic actuator of the stopper in accordance with the difference between actual engine speed during idling and the target idling speed. When the engine is not idling, the pneumatic actuator may be controlled to act as a dashpot, damping the return of the control lever to its idling position. Electromagnetically controlled valves respond to the control unit by providing atmospheric pressure or negative pressure to the pneumatic actuator. An auxiliary valve is provided for bypassing a defective atmospheric pressure supplying valve.

摘要： A first pump serves to periodically inject fuel into a combustion chamber of an internal combustion engine at a first timing in terms of crankshaft rotation, i.e., crank angle. A second pump serves to periodically inject fuel into the combustion engine at the first timing and also at a second timing in terms of crank angle. The second timing precedes the first timing. The rate of fuel injection by the second pump at the first timing is inversely related to the rate of fuel injection by the second pump at the second timing.

摘要： A fuel supply apparatus for a diesel engine includes a fuel tank and a fuel injection pump. The fuel injection pump has an inlet and an overflow outlet. A fuel feed line connects the fuel tank to the inlet of the fuel injection pump. A fuel feed pump is disposed in the fuel feed line to supply fuel from the fuel tank to the fuel injection pump. A fuel filter is disposed along the fuel feed line. A main fuel return line connects the overflow outlet of the fuel injection pump to the fuel tank. An auxiliary fuel return line connects the overflow outlet of the fuel injection pump to the fuel feed line at a position upstream of the fuel filter. A control valve is disposed in the auxiliary fuel return line to selectively block the latter. A device drives the control valve in response to the temperature of fuel in the fuel filter so that the control valve will block the auxiliary fuel return line only when the temperature of fuel in the fuel filter is higher than a preset value.

摘要： A fuel injection pump, for internal combustion engines, wherein a fuel distributing plunger moves angularly and axially in synchronism with the rotation of the engine and which cooperates with a control sleeve which determines the beginning or termination of injection into the cylinders. The control sleeve is controlled by an electrical motor through the motor's rotating shaft which is biased by an urging device circumferentially. The motor shaft is rotated to a predetermined position where the amount of injected fuel becomes small enough to keep engine operation safe if the motor output force exerted on the motor shaft disappears owing to a defect occurring.

摘要： A governor sleeve is axially displaceable on a stationary governor shaft and has an inner space which is adjoined by the governor shaft and which communicates with the inner chamber of a pump housing charged with fuel. The inner space varies in volume drawing thereinto and discharging therefrom fuel in response to axial displacement of the governor sleeve. According to the present invention, there is provided a helical groove which is formed in the outer cylindrical surface of the governor shaft or the inner cylindrical surface of the governor sleeve. Such groove effects a forced fuel conveying action of forcedly, though yieldingly, conveying fuel from the inner chamber to the inner space, which is effective in preventing an acceleration jerk and smoky exhaust upon rapid engine acceleration.

摘要： The degree of deterioration of lubricating oil used in an internal combustion engine is detected by measuring the lubricating oil dielectric constant with a pair of spaced sensor capacitor electrodes in the lubricating oil. The sensor capacitor is connected to a fixed capacitor to form a voltage divider connected across a constant frequency AC voltage source so that a developed voltage across the sensor capacitor corresponds to the lubricating oil dielectric constant. The frequency of the AC voltage is set at a value ranging from 50 KHz to 500 KHz.
