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 a certain control sequence of steps in a positive load variation and a certain control sequence of steps in a negative load variation.

대표청구항 ▼

What is claimed is: 1. A method for the control of an internal combustion engine combined with a gas-dynamic pressure wave machine, said gas-dynamic pressure wave machine comprising a rotatable housing in order to regulate 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 or a variable gas pocket said method, in a positive load variation, comprising the following steps in the order named: the operating speed and the rotation of the housing of the gas-dynamic pressure wave machine being adjusted 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 being adjusted for the charging pressure required according to the performance field of the engine; and said method, in a negative load variation, comprising the following steps in the order named: the operating speed and the rotation of the housing of the gas-dynamic pressure wave machine being adjusted 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 being 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. 2. The method of claim 1, wherein the rotatable housing of the gas-dynamic pressure wave machine is the air housing. 3. The method of claim 1 in a negative load variation, wherein it is ensured that a connecting duct provided between the high pressure charge air channel and the high pressure exhaust gas channel is certainly closed. 4. The method of claim 3, wherein a valve in said connecting duct is actuated by the control of the internal combustion engine through an actuating member. 5. The method of claim 3, wherein at the beginning of the negative load variation, the scavenging air flap is closed as far as possible without causing a collapse of the rotor scavenging. 6. The method of claim 1, wherein at the beginning of the positive load variation, while the control element of the internal combustion engine is displaced in accordance with the driver's demand for more power, a scavenging air flap in the intake channel of the gas-dynamic pressure wave machine is opened as far as possible. 7. The method of claim 6, wherein a connecting duct between the high pressure charge air channel and the high pressure exhaust gas channel is additionally opened in a positive load variation if the required charging pressure is not attained. 8. The method of claim 7, wherein said opening is affected in a range of Neng=1000-3000 r/min. 9. The method of claim 7, wherein said opening is only affected when all other parameters and actuating members are already in their optimum positions after the positive load variation.
