摘要： A fuel injection nozzle controls the flow of pressurized fluid through a nozzle opening. The fuel pump includes a fuel valve under the control of an electronic engine control module to effect sequential ON/OFF cycles for the fuel valve to establish a pilot fuel delivery pulse through the nozzle followed by a full fuel delivery injection pulse, a damping flow passage in the nozzle, and a flow damping pin in the opening through which fuel flows as the needle valve displaces fuel, the damping pin being biased toward an injection nozzle closed position by a needle valve spring whereby a distinct pilot pulse of fuel is delivered through the nozzle in advance of delivery of a full injection pulse, the valve spring being in a spring chamber that is pressurized to effect a rapid needle valve closure at the end of the fuel delivery pulse.

摘要： A method of utilizing the first valve bounce is used in a diesel engine having a solenoid valve controlled fuel injection system, wherein the solenoid-actuated valve is movable between a fully closed position for injection and a fully open position preventing injection. The method includes: (1) energizing the solenoid for valve movement to the fully closed position for commencing pilot injection; (2) de-energizing the solenoid immediately prior to the valve reaching the fully closed position for pilot injection in order to facilitate movement of the valve toward the fully open position immediately after the valve has reached the fully closed position, thereby preventing subsequent valve bounces; and (3) re-energizing the solenoid immediately prior to the valve reaching the fully open position, whereby to facilitate movement of the valve toward the fully closed position for main injection immediately after the valve reaches the fully open position, thus preventing subsequent valve bounces and decreasing time lag between pilot and main injection.
