摘要： A fuel control solenoid valve for metering fuel flow through a low pressure fuel injection system of an internal combustion system is provided. The low pressure fuel injection system including the fuel flow solenoid valve is especially suitable for use in providing fuel to a two-cycle internal combustion engine, particularly those that are suitable for use as marine outboard motors. The fuel control solenoid valve includes a non-magnetic spacer which substantially prevents the development of engine surging as peak power conditions are approached or reached.

摘要： Disclosed is a device for injecting fuel into an intake air supply passage which is communicated with the combustion chambers of an internal combustion engine.The device comprises: a swingable throttle shaft having a hole formed therein along a longitudinal axis thereof and traversing an intake air supply passage; a throttle valve plate fixed to the throttle shaft for throttling the intake air supply passage so that the throttle valve plate can vary the opening of the air supply passage due to the swing of the throttle shaft; and a fuel injection outlet portion formed at the proximity of the surface of the throttle valve plate and communicated with one of the hole. Fuel supplied from the fuel injection outlet portion is uniformly admixed with the air flow which is caused to contract by the throttle valve plate.

摘要： An improved device for controlling, either directly or indirectly, the injection of pressurized fuel into an internal combustion engine. The device comprises a body having a fuel inlet, a fuel outlet and a fuel return, as well as a valve mounted therein. The valve is actuated by an electromagnet and is adapted to establish communication between the fuel inlet and the fuel outlet when the valve is actuated. The device has a fuel accumulator comprising an opening in one side of the body and a diaphragm mounted across the opening to form an enclosed volume within the body. The enclosed volume communicates with the fuel input so that the diaphragm deflects outwardly with respect to the interior of the body in response to increases in the pressure of the pressurized fuel provided to the fuel input. The improvement comprises a pressure regulator having a regulatory valve disposed within the body and actuated by the diaphragm. The regulatory valve has an input in communication with the enclosed volume and an output in communication with the fuel return. The regulatory valve is adapted to establish communication between the enclosed volume and the fuel return when the pressure of the pressurized fuel in the enclosed volume reaches a predetermined value.

摘要： A fuel injector body has a fuel chamber and a valve seat around a fuel outlet. A valve body is positioned at the valve seat and a valve stem extends through the fuel outlet and fuel chamber. Engagement (disengagement) of valve body and valve seat closes (opens) the injector. The fuel chamber can comprise primary and secondary chambers connected by a valve passage and a metering member that restricts fuel flow between the chambers, thereby providing a flow-dependent closing force that reduces the dependence of fuel flow through the injector on fuel inlet pressure and that makes that flow dependent on an injector actuating force. The injector body or the valve body can comprise a spray-shaping surface arranged at least partly around the valve seat, which spray-shaping surface is arranged to direct a spray of fuel flowing through the fuel outlet.

摘要： A fuel injection device for internal combustion engines having externally supplied ignition, which enables introducing fuel injection quantities into combustion chambers in a manner that is controlled precisely in terms of quantity and of the instant of injection. The fuel injection device includes a first magnet valve by which fuel at injection pressure is pre-stored in a reservoir chamber, and the pre-stored quantity is ascertained by measurement of the deflection stroke of a reservoir piston which defines the reservoir chamber. Once the pre-storing process is complete, the pre-stored fuel quantity is then delivered to the injection valve with the air of a second magnetic valve. All that the fuel injection pump needs besides the two magnet valves and a control unit is a pre-feed pump, which pumps fuel into a high-pressure reservoir, so that while making limited demands on the pump generating the high pressure, a simple and very precisely functioning fuel injection device is created.

摘要： Improvements in electromagnetic control injection systems for diesel engines of the pressure-time type where the injection needle is controlled by the discharging then charging of a chamber. Electromagnetic control fuel injection system for diesel engines in which a three-way solenoid valve is placed in the injection holder, the injector needle being controlled during its opening by the pressure drop of the fuel contained in the control space. A disc having a nozzle is used to throttle the passage assuring the pressure drop in the control chamber without throttling the passage during a rise in pressure so that the injector needle begins to move only after the complete movement of the solenoid valve.
