Abstract
A method to control a fuel pump for a direct injection system provided with a common rail comprising the steps of calculating the objective fuel flow rate to be fed by the high pressure pump to the common rail instant by instant to have the desired pressure value inside the common rail; comparing the objective fuel flow rate with the maximum flow rate that can be delivered by the high pressure pump; and, based on the comparison between the objective fuel flow rate and the maximum flow rate that can be delivered by the high pressure pump, controlling the high pressure pump so as to alternate operating cycles of the high pressure pump with the maximum flow rate that can be delivered and idle operating cycles of the high pressure pump.
