Method for managing common rail injection system of e.g. direct injection diesel engine of car, involves determining control signal of injection circuit, and transmitting signal towards pressurization unit to control pressure of circuit

摘要

The method involves receiving a measured value of a temperature (202), and comparing the received temperature value with a threshold value (203). A nominal value of an engine torque is received (205). A measured value of the engine torque is received (206), and a control signal of an injection circuit is determined (208) according to a desired operation point of an engine, the received temperature value and a desired temperature value. The control signal is transmitted (210) towards a pressurization unit to control a pressure of the injection circuit. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions for executing a method for managing an injection system of an engine (2) a device for managing an injection system of an engine (3) an injection system (4) a car.
