Title:
METHOD FOR CONTROLLING THE BOOST PRESSURE ON A PISTON INTERNAL COMBUSTION ENGINE WITH A TURBOCHARGER
Document Type and Number:
WIPO Patent Application WO2001044641
Kind Code:
A3
Abstract:
The invention relates to a method for controlling the boost pressure on an unsteady-running piston internal combustion engine with a turbocharger. According to the inventive method, a blow-off valve, which is connected upstream from the supercharger turbine in the exhaust gas tract, is controlled by an engine control, the position of the pedal and a boost-proportional gradient are detected by the engine control when initiating an acceleration operation and, when a predeterminable value for the boost-proportional gradient is surpassed, the blow-off valve is actuated in an opening direction in order to effect a predeterminable controlled increase of pressure.
