Title: METHOD FOR THE EARLY OPENING OF A DISCHARGE VALVE FOR A TURBOCHARGED HEAT ENGINE
Abstract:
The invention relates mainly to a method for controlling the early opening of a discharge valve associated with a discharge conduit, said discharge conduit having an upstream end arranged upstream of a heat engine compressor and a downstream end arranged downstream of said compressor, characterised in that said method comprises: a step (100) of detecting a time-sensitive case that may cause a pumping phenomenon; and a step (105) of controlling early opening of said discharge valve following the detection of the time-sensitive case.
