Abstract

In an internal combustion engine a control valve (14) is arranged in the fresh air line (3) between the turbocompressor (5) of the turbocharger (11) and the intake opening of the cylinder. A turbocharger (11), the air delivery of which is equal to the fresh air demand of the engine (1) when the engine (1) is at full load and at half the rated speed of the engine (1), is adjusted to the engine (1). Within the said range of revolutions a pressure ratio defined by the admissible maximum combustion peak pressure can be observed, the amount of air delivered when the engine is at the rated speed exceeding the fresh air demand of the engine by up to 10%. The excess air delivered by the turbocompressor (5) is released by way of the automatic control valve (14) adjusted to the permissible maximum overcharging pressure. In order to achieve a uniform torque curve, tuned intake pressure charging is applied in the fresh air system, which charging is matched to that engine speed range in which the maximum combustion peak pressure could not be attained without the use of tuned intake pressure charging. <IMAGE>
