摘要：: The method for the control of an internal combustion engine combined with a gas-dynamic pressure wave machine comprising a rotatable housing in order to control the process tuning over the entire performance field of the internal combustion engine as well as a variable width adjustment of the high pressure exhaust gas channel includes the following steps, while a certain control sequence is followed in each area of the performance field: the operating speed and the housing of the gas-dynamic pressure wave machine are adjusted, in a positive load variation, by suitable means to the optimum position as stored in the performance field, and the variable width adjustment of the high pressure exhaust gas channel or the variable gas pocket inlet is adjusted for the charging pressure required according to the performance field of the engine; and the operating speed and the housing of the gas-dynamic pressure wave machine are adjusted, in a negative load variation, by suitable means to the optimum position as stored in the performance field, and the variable width adjustment of the high pressure exhaust gas channel or the variable gas pocket inlet is opened as far as possible in order to keep the pressure difference between the high pressure charge air and the high pressure exhaust gas as low as possible. Such a control sequence avoids damages of the gas-dynamic pressure wave machine and optimizes the operation as well as the power of the internal combustion engine.
