<p>FUEL INJECTION VALVE AND SINGLE POINT SYSTEM An electromagnetically actuated fuel injection valve and its utilization in a dual plane, single point fuel injection system are disclosed. The single point injection system includes a throttle body having an air induction bore controlled by a throttle assembly for each plane of the internal combustion engine manifold. An integrally formed fuel injector jacket mounts an injector valve above the throttle blade and concentrically with each bore of the throttle body without a hard fuel connection to the valve. The injection valve includes a movable valve needle attached to the armature of an electromagnetic solenoid. The needle seats between an inlet orifice and a metering orifice of a valve housing which is inserted into the accumulation chamber defined by the inner wall of the injector jacket. A flexible or soft connection is maintained between the valve housing and injector jacket to seal the accumulator chamber and to provide for quickly mounting or removing the valve from the system.</p> |
