High lift pump transfer interval determining method for heat engine, involves determining pressure gradient of high lift pump, during starting of fuel metering unit, and determining transfer interval of pump with help of gradient
The method involves determining pressure gradient of a high lift pump (30), during starting of a fuel metering unit (1), and determining a transfer interval of the pump with the help of the gradient. Starting of the interval is defined by an instant at which a time derivative of the gradient is greater than a threshold, and an end of the interval is defined by an instant at which the gradient derivative is less than the threshold. An independent claim is also included for a device for implementing a method of determining transfer interval of a high lift pump.
