    摘要： A high-pressure fuel injection system for a diesel engine including a plurality of main pumps for injecting fuel (200) each located at one of cylinders of the engine and formed with a fuel injection port (232), a metering and distributing pump (100) formed with fuel discharge ports (29, 30, 31, 23, 24, 25) corresponding in number to the cylinders of the engine for discharging fuel to be injected in timed relation to the rotation of the engine, a plurality of injected fuel metering valves (15, 16) for metering the fuel to be injected before introduction into the metering and distributing pump, a plurality of pipes (104, 105) for fluidly connecting each of the main pumps for injecting fuel with each other discharge ports of the metering and distributing pump, and an actuating mechanism (103, 109, 110, 111) connecting the engine with each of the main pumps for injecting fuel to actuate each of the main fuel injection pump for injecting fuel in timed relation to the rotation of the engine.

    摘要： The invention relates to a fuel injection system (1) for an internal combustion engine. According to the inventive system, the fuel is injected into the combustion chamber of the internal combustion engine via injectors (10; 61) with at least two different fuel pressures. A hydraulic pressure multiplicator (11) that generates the higher fuel pressure is provided in parallel to a by-pass line (19). Said pressure multiplicator (11) can be activated and deactivated via a valve unit (13). The invention provides a fuel injection system with an improved efficiency since the pressure multiplicator is not permanently operated and the losses through friction are reduced.

    摘要： Apparatus for the distribution of measured quantities of liquid fuel into the induction tracts of a multi-cylinder spark ignition internal combustion engine in which a single fuel metering device (33) is arranged to deliver metered quantities of fuel in accordance with the requirements of the cylinders of the engine into a catchment chamber (21) from which passages (22, 23, 24, 25) extend, each passage connecting to a conduct (31, 32) extending to the induction tract of one cylinder. Gas under pressure is supplied to the catchment chamber in such an amount and in such a direction that discrete quantities of fuel are delivered in turn along the passages (22, 23, 24, 25) to the cylinders. Preferably, the introduction of gas under pressure is controlled by means of solenoid valves (38, 39), one for each cylinder the operation of which is controlled by a timing device.
