摘要： A fuel injection valve comprises a hollow body in which there is formed a fuel circuit having an outlet opening. A guide member has a stem located in the passage and secured to the body. A bulged end portion of the guide member projects through the opening and is formed with a valve seat surface. An annular valve closure member is slidably mounted on the guide member and sealingly movable in the opening. A coil in the body is adapted to move a valve closure member into an abutment position clear from the seat. When the valve closure member is in that open position, a conical jet of fuel is delivered by the valve.

摘要： A single point fuel injection system for an internal combustion engine including a throttle body having first and second air intake throats corresponding to first and second intake manifold planes of the engine, the air flow through each throat being controlled by throttle plates positioned within each throat. The throttle body further includes a fuel accumulating bowl which is integrally formed with the throttle body, the bowl being enclosed by a diaphragm and cover member. Within the enclosure of the fuel bowl are positioned a pair of injectors which are adapted to inject pulsed portions of fuel through a sonic nozzle and into the air intake throat of the throttle body. The injection of pulses of fuel into the throat is timed in accordance with the sensing of the crankshaft reaching a position of 15.degree. before top dead center to enhance the distribution of fuel charge from cylinder to cylinder. The fuel pressure within the bowl is controlled by a pressure regulator positioned within the enclosure formed by the bowl and housing cover, the diaphragm closing the bowl also forming the diaphragm for the regulator. The pulses to the injectors are controlled by an electronic control unit in response to sensed engine conditions.

摘要： An electromagnetic fuel injector for a fuel injection system is provided with a solenoid winding which, when fed with electrical operating current, produces a saturated magnetic field in at least part of a magnetic circuit, which field is used to attract a member controlling the valve means of the injector and hence the fuel flow. The valve means may include a plunger having a tip portion of a plastics or rubber-like material to engage the valve seat. Methods of attaching the tip portion to the plunger are also described.

摘要： Liquid fuel is injected under pressure into the induction pipe downstream of the main throttle valve. The fuel flow is metered to the injection orifice by a valve actuated by an electromagnet according to the airflow in the induction pipe. The injection orifice is aligned with an auxiliary orifice in an air chamber at constant pressure. The airflow to the chamber is carried close to the electromagnet so as to cool it.

摘要： An injection hole has an injection hole passage communicating an inner opening with an outer opening. The inner opening is smaller than the outer opening in cross-sectional area. The needle moves in a valve closing direction to abut against a valve seat to restrict a flow of fuel through the injection hole. A first inner wall of the injection hole is located on a valve closing direction side relative to an injection hole axis. A second inner wall of the injection hole is located on an opposite side of the injection hole axis from the valve closing direction side. The injection hole passage is defined by the first inner wall and the second inner wall.
