摘要： The invention relates to a fuel delivery system for an internal combustion engine, having a fuel feed pump (10), which delivers fuel which is at pilot pressure to a high-pressure fuel pump (11) that communicates on the high-pressure side with at least one injection valve (14), in order to deliver fuel at high pressure to the injection valve or valves (14). To prevent vapor bubble development in the high-pressure fuel pump (11), which impairs its pumping capacity and pressure generation, it is provided according to the invention that a coolant medium flow can be delivered to the high-pressure fuel pump (11) via at least one coolant conduit (21, 31), in order to keep the temperature (THDP) of the high-pressure fuel pump (11) below a critical operating temperature (Tk1).

摘要： A number of embodiments of direct injected V-type outboard motors provided with a very effective fuel supply system wherein the number of components can be significantly reduced as well as the elimination of many of the flexible conduits normally employed. This also permits the fuel system to be assembled as a relatively unitary assembly that can be then affixed to the engine. The arrangement is such that purging of the system from vapors during shutdowns is easily accomplished and the system can be purged without complicated construction. Furthermore, the system can be pressure tested by an arrangement where the low pressure system can bypass the high pressure system when the engine is not operating so as to be pressurized for testing purposes. However, when the high pressure system operates, then the bypass line will be closed by the shunting valve arrangement. The direct injection system permits operation with two cycle engines even under low load and speed conditions by using residual gasses to assist in fuel vaporization. The high pressure pump and its drive are also provided with a cooling system.
摘要翻译：直接喷射的V型舷外马达的许多实施例具有非常有效的燃料供应系统，其中可以显着减少部件的数量以及消除正常使用的许多柔性导管。这也允许燃料系统被组装成相对单一的组件，然后将其固定到发动机。这样做是为了在关闭期间从蒸气中清除系统容易实现，并且可以在没有复杂结构的情况下清洗系统。此外，该系统可以通过一种布置进行压力测试，其中当发动机不工作时，低压系统可以绕过高压系统，以便为了测试目的被加压。然而，当高压系统工作时，旁路管路将被分流阀装置关闭。即使在低负载和速度条件下，直接喷射系统也允许使用两循环发动机，通过使用残留气体来辅助燃料蒸发。高压泵及其驱动器还设有冷却系统。

摘要： A fuel supply system is disclosed for a direct injected “V” type engine powering an outboard motor. The fuel supply system includes a pump for supplying fuel from a tank to a vapor separator. An electrical pump delivers fuel from the vapor separator to a mechanical high pressure pump, which delivers fuel under high pressure to a fuel manifold and further to a pair of fuel rails. The fuel rails supply fuel to fuel injectors for delivering fuel to the combustion chambers of the engine. Recesses are formed on a side of each cylinder head and one fuel rail is positioned within each recess. The mechanical high pressure pump is positioned vertically above the uppermost fuel injector so that any fuel vapor within the fuel rails will rise toward the fuel pump. Fuel vapor that accumulates within the high pressure fuel pump is returned to the vapor separator.

摘要： In a high-pressure fuel supplying apparatus, fuel is pumped from a fuel tank by a feed pump into a fuel gallery of a high-pressure pump via a low-pressure fuel passage. The low-pressure fuel passage can include a reservoir chamber that is formed by vertically upwardly expanding a portion of the passage located near the fuel gallery. The reservoir chamber is located above an upper end of the fuel gallery in a vertical direction. A communication passage, forming a portion of the low-pressure fuel passage, can be connected at one end thereof to an upper end portion of the fuel gallery. Another end portion of the communication passage extends diagonally upward from the upper end portion of the fuel gallery, and connects to the reservoir chamber. According to other embodiments, the reservoir chamber can be omitted as long as a portion of the communication passage is provided vertically above an upper end of the fuel gallery. Alternatively, the communication passage can lead to (and convey the fuel vapor produced in the fuel gallery to) an auxiliary injector or to a dedicated reservoir chamber that is separate from the low-pressure fuel passage.

摘要： Pressurized fuel of a common rail is introduced into a control chamber of a fuel injector. An electromagnetic valve opens or closes a fuel discharge passage of the control chamber to adjust a hydraulic pressure of the control chamber. Through a switching leak passage, bubble-containing fuel directly returns from a valve opening of the electromagnetic valve to a low-pressure return passage without passing through an armature chamber. Through a stationary leak passage, the fuel leaking from every slide portion returns to the return passage via the armature chamber. A downstream portion of the stationary leak passage opens to the upper portion of the armature chamber. A damper element is provided downstream of the electromagnetic valve in the return passage for canceling an increased fuel pressure.

摘要： A leak prevention device including an expandable chamber and control valve for preventing fuel leakage into the combustion chambers of a internal combustion engine equipped with a common rail fule injection system including open nozzle injectors and a shut off valve mounted in the common rail upstream of the fuel injectors to isolate, when closed, the fuel injectors from the source of fuel under pressure. The expandable chamber contains a variable volume held in its collapsed condition during engine operation and expanded upon engine shutdown sufficiently to prevent the flow of fuel from any injector into the corresponding combustion chamber. The control valve may be a three way valve for controlling the expansion of the variable volume of the expandable chamber The leak prevention device includes a housing assembly connected with a fuel drain and contains an outlet passage fluidically connected at one end with the variable volume and at the other end with the fuel drain and an outlet check valve for allowing fuel to flow in only one direction from the variable volume into the fuel drain. A control circuit is provided to energize solenoids for operating the shut off valve and control valve.

摘要： A fuel system for a diesel engine includes an air purging system for venting trapped air to a vent line connected to a fuel tank and an emergency shut-down system for providing a fail-safe shut-down of the engine when fuel is low. The air-purging system comprises a device defining a float chamber having an air outlet communicating with the vent line, a fuel inlet, and a fuel outlet. A float is disposed in the chamber and is adapted to move between a normal first position closing the air outlet, an emergency intermediate second position opening both the air and fuel outlets, and a shut-down third position opening the air outlet and closing the fuel outlet. The emergency shut-down system includes electronic and pressure sensitive switches, warning lights, and an auxiliary fuel pump to monitor and control the shut-down and restart modes of engine operation. The air purging system is adapted to function independently of the emergency shut-down system.
