ABSTRACT:
A method for supercharging internal combustion engines with turbochargers wherein the engine is operated in the lowest load region as a naturally aspirated engine, and the waste gate, the inlet section of the turbine and all other exhaust gas ducts present are fully open. When this load range is exceeded, the flow area of the turbine inlet is reduced to its minimum operational value and subsequently, with a further increase in load, is increased again to its maximum value at full load. The engine operated according to this method has a varioturbocharger whose turbine inlet flow area is controlled by a throttle slide as a function of the fuel injection quantity and the boost pressure by means of an adjustment device and a control pressure modulator.
