Abstract
Official abstract text for this publication.
A direct fuel injection system including a common rail and control unit, a pump, an on/off valve, controlled by the control unit, to regulate the volume of fuel sent to the pump to be fed into the common rail, the control unit including: first determination elements for determining a peak phase duration during which a command must be applied to the valve to obtain a peak current to cause a change of state of the valve; second determination elements for determining a holding ratio according to which a command must be applied to the valve, after its change of state, to maintain a holding current necessary to maintain the state of the valve; application elements for applying the command to the valve first continuously during the peak phase duration and then by pulse width modulation according to the holding ratio; and at least one recurrent and automatic adaptation element.
First claim
Opening claim text (preview).
The invention claimed is: 1. A direct fuel injection system including a common rail ( 4 ) including a control unit ( 1 ), a pump ( 2 ) and a valve ( 3 ), controlled on an on-or-off basis by the control unit ( 1 ), in order to regulate the volume of fuel sent to the pump ( 2 ) to be fed into the common rail ( 4 ), said control unit ( 1 ) comprising: first determination means ( 40 ) that determines a peak phase duration ( 27 ) during which a first command must be applied to the valv…
