UNIVERSAL CONTROLLER OF DIESEL ON THE BASIS OF ELECTRIC SERVO-ACTUATOR

An electronic actuator of a high-pressure fuel system for a transport diesel has been developed, the introduction of the actuator will allow to formulate optimum characteristics of a vehicle taking into account the conditions of its operation and co-ordination with any types of transmission and engine. The authors proposed a functional scheme and an algorithm for an electronic diesel actuator, based on the analogy with the operation of a mechanical spring-lever governor of direct action. The algorithm of the HEINZMANN actuator positioning control subsystem (servo-actuator) is developed. The algorithm is built on the parallel operation of the positional and proportional-differential-isodromic actuators. The motorless research of the high-pressure fuel pump BOSCH PES 4P 100A, equipped with an electric servo-actuator, showed that the electronic governor system developed by the authors can provide identical with a regular mechanical governor characteristics and could be easily adapted to the any necessary regulatory characteristics of the engine.
