Abstract

Una disposicion de control para una bomba de inyeccion de combustible rotativa que tiene un piston del regulador, controlado por un motor del regulador,para ajustar la regulacion de inyeccion de la bomba. El piston del regulador incluye un alojamiento que contiene un volumen de fluido hidráulico que essometido a un pico de presion que tiene una presion pico durante cada evento de bombeo. Un detector de punto muerto superior detecta cuando el ciguenal delmotor diesel está en el punto muerto superior y proporciona una salida de senal de referencia de punto muerto superior. Un transductor de presion montado en elalojamiento del piston regulador tiene respuesta a la presion del fluido hidráulico y proporciona una salida de senal de presion indicativa de la presion delfluido hidráulico. Un controlador del motor tiene una porcion de entrada de senales en comunicacion eléctrica con el detector de punto muerto superior y eltransductor de presion y una porcion de control del motor en comunicacion eléctrica con la porcion de entrada de senales y el motor de control del regulador.La porcion de entrada de senales del controlador del motor incluye una seccion de deteccion de la posicion de la leva que proporciona una senal de posicion dela leva, una seccion de deteccion de la velocidad de la bomba que proporciona una senal de la velocidad de la bomba, y una seccion de deteccion de combustibleadministrado que proporciona una senal de la cantidad de combustible administrado.A control arrangement for a rotary fuel injection pump having a regulator piston, controlled by a regulator motor, to adjust the injection regulation of the pump. The regulator piston includes a housing that contains a volume of hydraulic fluid that is subjected to a pressure peak that has a peak pressure during each pumping event. An upper dead center detector detects when the diesel engine crankshaft is in the upper dead center and provides an upper dead center reference signal output. A pressure transducer mounted on the loosening of the regulating piston responds to the pressure of the hydraulic fluid and provides a pressure signal output indicative of the hydraulic fluid pressure. An engine controller has a signal input portion in electrical communication with the upper dead center detector and the pressure transducer and a motor control portion in electrical communication with the signal input portion and the regulator control motor. The motor controller's signal input portion includes a cam position detection section that provides a cam position signal, a pump speed detection section that provides a pump speed signal , and an administered fuel detection section that provides a signal of the amount of fuel administered.
