摘要： A feed back control system and method for direct injected engines useful in a start up operation that utilizes a fuel pressure condition sensor. At the commencement of cranking, the feed back control system adjusts at least the initiation of fuel injection based upon the output from the fuel pressure condition sensor. This removes a great shift in the fuel pressure between before and after starting of the engine and eventually promotes operator's feeling and also improves exhaust emissions.

摘要： A method for controlling the operation of a fuel system of an outboard motor uses a lift pump to transfer fuel from a remote tank to a vapor separator tank. Only one level sensor is provided in the vapor separator tank and an engine control unit monitors the total fuel usage subsequent to the most recent filling of the tank. When the fuel usage indicates that the fuel level in the vapor separator tank has reached a predefined lower level, a lift pump is activated to draw fuel from a remote tank and provide that fuel to the vapor separator tank.

摘要： A device for preventing fuel pump air ingestion in a diesel fuel system includes a diesel engine having a plurality of injectors. The injectors receive a supply of diesel fuel from a fuel injection pump at a high pressure. The fuel injection pump receives the supply of diesel fuel from a transfer pump at a transfer pressure through a transfer pressure gallery. The supply of diesel fuel is stored in a fuel tank coupled to the transfer pump through a fuel line. To prevent air from entering the diesel fuel system, a low pressure sensing switch is coupled to the transfer pressure gallery and senses the transfer pressure. When the transfer pressure drops below a predetermined pressure a controller disables the fuel injection pump. Once the transfer pressure rises above the predetermined pressure level the controller enables the fuel injection pump.

摘要： A fuel system and method for priming a diesel engine fuel system after assembly or when run out of fuel in which the system has a filter that can trap air allowing drainback of fuel to the tank. The system is provided with a fuel priming connection to the injection pump inlet, the connection having a closure for shutting the connection when not in use. A mechanically openable check valve, such as a Schraeder valve, is a preferred form of closure. The system is primed by reverse flow of fuel from the priming connection through the filter to the fuel tank to virtually eliminate trapped air from the system. The engine may then be started with a minimum of cranking. The engine may be restarted after running out of fuel by partially filling the tank and operating the normal feed pump while bleeding air from the system through the priming connection, which is closed prior to engine starting. The engine may then be reprimed after shutdown if required.
摘要翻译：一种燃料系统和方法，用于在组装之后或当燃料耗尽时启动柴油发动机燃料系统，其中系统具有可以捕获允许将油排出到罐的空气的过滤器。该系统设置有与注射泵入口的燃料起动连接，该连接具有用于在不使用时关闭连接的闭合件。一种可机械打开的止回阀，例如Schraeder阀，是一种优选的封闭形式。该系统通过燃料从起动连接通过过滤器逆向流动到燃料箱来实际消除来自系统的被捕获的空气。然后可以以最少的起动起动发动机。发动机可能在燃料耗尽后通过部分填充油箱并操作普通进料泵，同时通过在发动机启动之前关闭的系统的空气排出空气。如果需要，发动机可能在停机后重新启动。

摘要： Fuel in a fuel tank is pressurized by a fuel pump and supplied to a fuel gallery. When a fuel injection valve connecting with this gallery is opened by an electromagnetic signal, fuel is injected from the valve into a combustion chamber of the engine. The fuel gallery is formed inside a cylinder head, and the fuel injection valve is disposed in the cylinder head such that a fuel inlet port of the valve faces the gallery. In this manner, a high pressure fuel passage does not project outside the cylinder head, and there is less risk of fuel leaking from the passage. Further, as the high pressure fuel passage does not project outside the engine, the piping around the engine is simplified.
摘要翻译：燃料箱中的燃料由燃料泵加压并供给燃料库。当通过电磁信号打开与该通道连接的燃料喷射阀时，将燃料从阀注入发动机的燃烧室。燃料箱形成在气缸盖内部，燃料喷射阀设置在气缸盖中，使得阀的燃料入口端口朝向画廊。以这种方式，高压燃料通道不会突出到气缸盖的外部，并且从通道泄漏燃料的风险较小。此外，由于高压燃料通路不会在发动机外部突出，因此简化了发动机周围的配管。

摘要： A fuel system has a fuel tank with a wall and a fuel delivery outlet through which fuel is delivered to the engine. The fuel tank has a fuel suction tube extending from the fuel delivery outlet into the fuel tank. Fuel is drawn to the engine from the fuel tank through the suction tube and the fuel delivery outlet. The fuel tank has a fuel cooling return inlet through which unused fuel warmed by the engine may be returned to the fuel tank and cooled. A fuel cooling conduit is coupled to the fuel cooling return inlet. The fuel cooling conduit has at least one fuel dispersing outlet through which fuel is dispersed onto the fuel tank wall to cool the fuel. A fuel warming return inlet is provided through which unused fuel warmed by the engine may be directed to flow adjacent the suction tube to heat the fuel being delivered through the suction tube to the engine. A shroud may also be provided to blend returning warm fuel with cooler fuel from the fuel tank that is flowing toward the suction tube.

摘要： A fuel pressure regulator for a no-return fuel system for an automotive engine with fuel injectors having a housing with a flexible diaphragm between first and second chambers. The second chamber has a fuel inlet with a valve therein to admit fuel to the second chamber and an outlet to supply fuel to the engine. The second chamber is in continuous communication with the engine to accumulate any fuel expansion that may occur during engine deceleration or when the engine is turned off due to heating the fuel. The first chamber continuously communicates with the engine air intake manifold so that fuel is supplied to the engine fuel injectors at a substantially constant pressure drop across the injectors.

摘要： A fuel pump manifold for a no-return fuel system for an automotive engine. The manifold has inlet and outlet passages with a check valve which opens when fuel is supplied to the engine and closes to prevent reverse flow of fuel when the outlet pressure is greater than the inlet pressure and a vent valve between the outlet and inlet and in parallel with the check valve which is normally closed and opens when the outlet pressure exceeds the inlet pressure by at least a predetermined minimum value which is usually the desired minimum pressure of fuel supplied to the operating engine when idling. Preferably, a normally closed pressure relief valve also communicates with the outlet to relieve overpressure of the outlet fuel supplied to the engine.
