摘要： A device for injecting fuel into the combustion chamber of an internal combustion engine, a high-pressure accumulator, a pressure booster, and a metering valve. The pressure booster has a working chamber and a control chamber that are separated from each other by an axially moving piston. A pressure change in the control chamber of the pressure booster causes a pressure change in a compression chamber of the pressure booster. The compression chamber communicates with a hydraulic chamber that acts on an injection valve element. The piston that acts on the compression chamber of the pressure booster is provided with control sections that can be used to relieve the pressure in the hydraulic chamber of the injection valve element.

摘要： A pilot injection controller and a method of controlling pilot injection quantity enable the quantity of fuel pilot-injected fuel by an internal combustion engine fuel injection system of the type in which the fuel delivery stroke for pilot injection is fixed to be maintained substantially constant irrespective of engine speed by controlling prestroke such that the utilized portion of a cam is shifted to a lower delivery velocity region thereof with increasing engine speed, the principle involved being that the quantity of fuel pilot-injected by a fuel injection system is proportional to the actual plunger delivery velocity and the fact that since the actual delivery velocity is proportional to the product of the cam velocity constant and the cam rotational speed the actual delivery velocity can be maintained substantially constant by increasing the cam velocity constant in the low speed region and decreasing the cam velocity constant in the high speed region.

摘要： A fuel injection pump for internal combustion engines is proposed, in which to attain particularly quiet operation of an engine that is operated with direct injection, the fuel delivery is subdivided into a preinjection and a main injection; this injection is attained by annular groove, coinciding with one another, on the pump piston and pump cylinder, and a connecting groove connecting the coinciding annular grooves with a relief opening. After a partial stroke in the region of coincidence of the annular grooves with one another, the communication with the relief opening is interrupted again. The preinjection quantity can be kept particularly small here, with a short interval between the preinjection and the main injection; in combination with a two-spring-holder injection valve, this particularly small preinjection quantity can be kept constant to a great extent even at varying engine speeds, to attain an optimal reduction in combustion noise at various engine speeds.

摘要： An oil activated fuel injector which provides a pilot quantity of fuel prior to the main fuel injection event. The oil activated fuel injector includes a throttle which provides fluid communication between the high pressure chamber and a fuel bore which leads to the nozzle of the oil activated fuel injector. The pilot quantity of fuel flows through the throttle and into the fuel bore during a pre stroke of the plunger. The oil activated fuel injector reduces engine emissions and noise, and eliminates the need for additional working fluid to be provided therein in order to provide a pilot quantity of fuel.

摘要： A solenoid valve unit is provided in the middle of fuel supply path that leads to a compression space in an injection pump main body, and the fuel injection quantity is adjusted through the open and close control of the solenoid valve unit. In this fuel injection system, the plug valve is moved until it is seated on the valve seat during the preliminary injection that is performed prior to the main injection. An arrangement for leaking the fuel from within the compression space is provided in the injection pump main body and the time period during which the fuel in the compression space is leaked via the arrangement for leaking and the time period during which the fuel supply path is restricted with the plug valve being seated on the valve seat are combined to stabilize the movement of the plug valve. Consequently, an optimal small quantity is achieved for the preliminary injection that is nearly constant regardless of the rate of rotation of the engine. Also, if a drive pulse that closes the fuel supply path over the period during which the fuel is leaked is supplied to the solenoid valve unit, the solenoid valve unit needs to be operated only once and stable injection characteristics are achieved from the pilot injection through the main injection.
摘要翻译：在燃料供给路径的中间设置有电磁阀单元，其通向喷射泵主体中的压缩空间，并且通过电磁阀单元的打开和关闭控制来调节燃料喷射量。在该燃料喷射系统中，在主喷射之前执行的预喷射期间，旋塞阀被移动直到其被安置在阀座上。在喷射泵主体中设置有用于从压缩空间泄漏燃料的装置，以及经由泄漏装置和压缩空间中的燃料泄漏燃料供给路径被限制的时间段将旋塞阀置于阀座上的组合以稳定旋塞阀的运动。因此，无论发动机的旋转速度如何，初始喷射的最佳量都是几乎恒定的。此外，如果在燃料泄漏期间关闭燃料供给路径的驱动脉冲被供给到电磁阀单元，则电磁阀单元仅需要操作一次，并且从先导喷射通过主要注射。

摘要： A fuel injection pump for internal combustion engines, having a pump piston that is guided axially and rotationally movably in a cylinder bore of a cylinder liner and that with a face end defines a pump work chamber. The fuel injection pump pumps a quantity of fuel that is divided into a preinjection quantity and a main injection quantity. On a jacket face, this pump piston has known oblique grooves for the high-pressure pumping diversion process, and also a recess, which cooperates with an annular groove in the cylinder bore and with a control opening which discharges into a low-pressure chamber, and on its end face the piston has a cutout formed by two different, deep shoulders; the cutout is recessed within the annular groove continuously and cooperates with a first control opening that discharges into the low-pressure chamber. During the high-pressure pumping phase, depending on the rotary position of the pump piston, the pump work chamber can be relieved via the annular groove, the recess, and the control opening; this interruption in high-pressure pumping can be limited to the partial-load or the full-load range, depending on the embodiment.

摘要： A fuel injection pump for internal combustion engines, having a pump piston that reciprocates in a cylinder liner inserted into a pump housing. The pump piston and housing encloses a pump work chamber, and the pump piston has a control recess on its jacket face that communicates with the pump work chamber through a conduit. An oblique groove extends at a predetermined angle from the axis of the pump piston in the jacket face thereof and forms control edges. An annular slide is axially displaceable on the pump piston and includes two diametrically opposed diversion bores. To interrupt the high-pressure pumping to provide a pre-injection quantity and a main-injection quantity, first, second and third pockets are additionally machined into the jacket face of the pump piston. These pockets cooperated with pockets machined in the annular slide and with the control edge formed by the lower face edge of the annular slide to control the fuel flow.

摘要： A fuel injection pump is proposed in which over a first portion of the supply stroke of the pump piston fuel for the main injection is pumped via a distributor line and a distributor groove into one at a time of a plurality of fuel injection lines. In a second, remaining portion of the pump piston supply stroke, on the same cam flank, fuel is then pre-stored in a reservoir, controlled by a first electrically controlled valve and a second electrically controlled valve and by one of a plurality of longitudinal control grooves, which fuel subsequently, before the beginning of the next main injection determined by the closure of the first electrically controlled valve, is pumped via a second distributor line into the next succeeding injection line.
