摘要： In a fuel injection pump, a helical gear is attached to an end of a camshaft and rotatable with the camshaft. The camshaft is biased in one axial direction thereof by a driving force that the helical gear receives from an engine crankshaft. A disk is provided in a position of the camshaft extending forward from a cam to the direction in which the camshaft is biased. An axial movement of the disk is restricted via a washer by an end of a bearing cover. The disk is formed in the same axis to a portion of the camshaft that is held by a journal bearing. An outer diameter of the disk is larger than that of the cam. An area where the disk and the washer are in sliding contact with each other is relatively large and the sliding regions thereof are constant so that hammer noises are prevented and frictional wear thereof are limited.

摘要： A fuel delivery module for an automotive fuel delivery system includes a reservoir and a fuel pump. The fuel pump delivers fuel from the tank to the reservoir via a fuel tank inlet and reservoir outlet and from the reservoir to the engine via a reservoir inlet and engine outlet. The reservoir is formed with a plurality of contaminant traps for collecting contaminants contained in the fuel as the fuel is pumped through the reservoir such that the contaminants settle unto said contaminant traps thereby reducing the amount of contaminants entering the reservoir inlet.

摘要： A high-pressure fuel pump control device and an in-cylinder injection engine control device are provided in which a high-pressure fuel pump accelerates a rise in fuel pressure from the start-up of an engine thereby to make it possible to shorten an engine start-up time, reduce an exhaust gas substance and improve or increase an engine output, for example. The high-pressure fuel pump control device and in-cylinder injection engine control device control an in-cylinder injection engine having a fuel injection valve provided in a cylinder, a high-pressure fuel pump for force-feeding a fuel to the fuel injection valve, and a crank angle sensor for detecting the position of a crankshaft of the cylinder. The high-pressure fuel pump is provided with a plunger for pressurizing the fuel placed in the high-pressure fuel pump, a pump drive cam for driving the plunger, and a cam angle sensor for detecting the position of the pump drive camp. The high-pressure fuel pump control device and in-cylinder injection engine control device is provided with drive signal setting means for outputting drive signals to the high-pressure fuel pump at least two or more times from the time of signal detection of the crank angle sensor to the time of determination of the phases of the crank angle sensor and the cam angle sensor.

摘要： A watercraft includes an engine having a fuel injection system. The fuel injection system is controlled to gradually reduce a speed of the engine if a lubrication pressure detected within the engine is below a predetermined pressure. Additionally, the fuel injection system is controlled to maintain a reduced engine speed until the throttle lever is moved to a position corresponding to a lower speed.

摘要： An engine fuel delivery system is provided to raise the fuel pressure rapidly in the initial stage of engine starting without increasing the cranking load, thereby making it possible to achieve an atomized fuel spray through high-pressure fuel injection, improve the fuel efficiency, and reduce emissions. The engine fuel delivery system uses a variable transmission mechanism that is configured to change the drive rotational ratio of a power transmission path between a crankshaft of an engine and a high-pressure fuel pump. The variable transmission mechanism controls the rotational speed of the high-pressure fuel pump to a rotational speed that is higher than the normal pump rotational speed in the initial stage of engine starting after the engine has been cranked to complete explosion.

摘要： A high-pressure fuel pump (10) is used for a fuel system of a direct-injecting internal combustion engine. This pump includes a housing (14, 32). It is also provided with a low-pressure inlet (16) and a delivery chamber (20). The fuel is compressed in the delivery chamber (20). An insert (38) is also provided, which delimits the delivery chamber (20) in the direction toward the low-pressure inlet (16). The insert (38) contains at least one radial flow conduit (48). The insert (38) is axially supported against the housing (32). The high-pressure fuel pump (10) also has a high-pressure outlet (18). In order to reduce the manufacturing costs of the high-pressure fuel pump (10), the invention proposes that the radial flow conduit (48) be delimited by a recess in an axial end face (44) of the insert (38).

摘要： A fuel feed apparatus is accommodated in a fuel tank. Hooking projection parts have claws formed on a fuel discharge side of a fuel pump. The claws are fitted and hooked in an opening formed on a filter case, so that the fuel pump is protected from dropping out from the filter case. The entire circumference of the fuel discharge side of the fuel pump is inserted with force into a press-insertion part formed in the filter case. A fuel suction side of the fuel pump is not supported by other parts, so it is in free condition.
