摘要： A fuel injection system for internal combustion engines includes a high-pressure accumulator acted on with highly pressurized fuel by a high-pressure delivery unit and in turn supplies fuel to fuel injectors. The fuel injection system has a pressure control valve, which is disposed between a high-pressure side and a low-pressure side and actuating a valve element. The pressure control valve is actuated by means of an electrical actuator. An end surface of the pressure control valve delimits the low-pressure region in the high-pressure accumulator and is sealed by means of a seal disposed on the low-pressure side.

摘要： When an engine is cold-started, the engine oil is quite viscous and requires larger passageways to flow through the engine than when the engine is warmed up and the engine oil flows readily. The present invention relates to a pin valve assembly which may be used on a fuel injector of an engine. The pin valve assembly of the present invention includes a movable shuttle which allows for a relatively large fluid flow space within the pin valve assembly when the engine is cold, and then moves to reduce the fluid flow space when the engine oil is less viscous and requires less room to flow as desired. Therefore, the advantages of a relatively large fluid flow space as well as a shorter pin travel distance within the pin valve assembly are both preserved.

摘要： Fuel injectors equipped with direct control needle valves can add new capabilities to a fuel injection system, but can sometimes have difficulty in achieving low hydrocarbon emissions at levels comparable to ancestor fuel injectors that utilize a simple spring biased needle. The present invention seeks lower hydrocarbon emissions by reducing fuel pressure before the direct control needle valve member has reached its closed position toward the end of an injection event. Reducing fuel pressure can be accomplished in a number of ways depending upon the particular fuel injection system, including spilling fuel pressure in a cam system or possibly relieving pressure on an intensifier piston. By employing this strategy, fuel spray from the fuel injector can effectively end before the direct control needle valve member reaches its closed position, thus avoiding hydrocarbon production that could be caused by a small amount of fuel pushed into the combustion space as the needle moves over the last portion of its movement toward its closed position.
摘要翻译：装备有直接控制针阀的燃油喷射器可以为燃料喷射系统增加新的功能，但是有时难以实现与使用简单弹簧偏压针的祖先燃料喷射器相当的低碳氢化合物排放。本发明通过在直接控制针阀构件已经到达其关闭位置之前通过降低燃料压力来寻求更低的碳氢化合物排放，从而朝向喷射事件结束。取决于特定的燃料喷射系统，包括在凸轮系统中溢出燃料压力或可能减轻增压器活塞上的压力，可以以多种方式实现降低燃料压力。通过采用这种策略，在直接控制针阀构件到达其关闭位置之前，来自燃料喷射器的燃料喷射可以有效地结束，从而避免了由于当针移动时被少量的燃料推入燃烧空间而引起的碳氢化合物产生其运动的最后部分朝向其关闭位置。

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 known control valve, especially for controlling a piston of a pressure intensifier of an injection device for internal combustion engines is already known per se. Said control valve comprises a control valve housing, fluid lines and a control valve piston which can be displaced in a controlled manner in the housing in at least two operational positions. Said piston controls at least the fluidic connection between a first chamber and a second chamber having a first flow rate or a reduced second flow rate. In order to produce said control valve which enables the precise control of the reduced second flow rate and which is simple to construct, a throttle is provided. Said throttle adjusts the reduced second flow rate and is arranged outside the control valve piston and in front of the second chamber.

摘要： A solenoid includes first and second armatures disposed on either side of a solenoid core. The core includes first and second sets of legs disposed on opposite sides of a central member. A drive circuit provides a first current level to cause flux to flow in a first path through the core and thereby move the first armature without substantially moving the second armature. The drive circuit can provide a second current level greater than the first current level to saturate the first path and thereby redirect flux into a second core path to move the second armature.

摘要： In a common rail type fuel injection system, fuel in a fuel tank is sucked by a feed pump and fed to a pressurizing pump. Fuel pressurized in the pressurizing pump is supplied to a common rail. The pressurized fuel accumulated in the common rail is injected into a cylinder of an internal combustion engine from an injector. All of these operations are electronically controlled by an electronic control unit. To gradually suck air in the fuel tank together with fuel and to avoid air accumulation in a fuel filter, a relief valve is connected to the common rail. The relief valve is opened when the engine is idling thereby to increase an amount of fuel sucked by the feed pump and to gradually suck the air together with the fuel. The relief valve is opened only in interval periods in which fuel is not injected from the injector.
