Method for increasing performance of petrol engine of motor car, involves compensating responding behavior of turbocharger in partial load operation in which air is supplied to engine at beginning of sudden load variation in engine

摘要

The method involves storing oxygen-enriched air in a pressure storage (6), and compensating responding behavior of an exhaust-gas turbocharger (2) in a partial load operation in which the oxygen-enriched air is supplied to an internal combustion engine (1) at the beginning of sudden load variation in the engine. Recovery of the oxygen-enriched air is carried out by an oxygen concentrator (7) during a normal driving operation, where the charging of the pressure storage is carried out by using the turbocharger during a recuperation phase. An independent claim is also included for a motor car comprising an internal combustion engine.
