An automatically regulated fuel injection pump body plunger assembly

Abstract

The utility model relates to fuel injection pump body technical field, and disclose a kind of automatic regulation and control fuel injection pump body push rod assembly, including pump body, and push rod cavity is established in the inside of pump body.This automatic regulation and control fuel injection pump body push rod assembly, by rotational speed sensor real-time monitoring engine speed, and signal is fed back to controller, controller combines the main push rod position information that the magnetostrictive displacement sensor transmits, the operation of servo motor is regulated and controlled, when engine load increases, rotational speed drops, controller rapidly instructs servo motor to increase the rotation amplitude of eccentric wheel, so that main push rod boost piston generates greater stroke, to increase the fuel pressure of boost chamber, improve fuel injection quantity, timely satisfy engine power demand, so that fuel injection pump can always maintain optimum fuel supply state under different working conditions, improve fuel utilization, reduce engine fuel consumption and pollutant emission, significantly improve the comprehensive performance and operating stability of engine.
