摘要： A process for the load-dependent control of a hydraulic drive for a compressor arranged at an internal-combustion engine, the compressor being driven by a hydraulic motor that, in turn, is acted upon by pressure from a hydraulic pump, the internal-combustion engine itself driving the hydraulic pump. In order to ensure a relatively high compressor speed as early as during the idling operation of the internal-combustion engine, and have available an optimal torque for a positive load change, while keeping minimal the additional fuel consumption required for the hydraulic drive, during the idling operation of the internal-combustion engine, the hydraulic pump is adjusted into the full-delivery position and the hydraulic motor is adjusted into the minimum intake position. Upon a subsequent positive load change, after an indicated hydraulic motor control pressure is reached, the hydraulic motor is guided into the maximum intake position, and after an indicated hydraulic pump control pressure is reached, the hydraulic pump is guided into the direction of the minimum delivery position. After an indicated charging pressure limit is reached, the hydraulic drive is disconnected from the compressor. Also described is an arrangement for carrying out this process.

摘要： The invention concerns a supercharged internal combustion engine in which two inlet ducts, which can be closed by inlet valves and whose flows are separated from one another, and two exhaust ducts which can be closed by exhaust valves enter the combustion space of a cylinder, one inlet duct and one exhaust duct being associated with one exhaust gas turbocharger. In order to achieve both a rapid build-up of supercharge pressure in the case of positive load changes and also an optimum homogenization of the mixture in the combustion space, the two exhaust ducts are also arranged so that their flows are separated and the inlet and exhaust side connected to the same exhaust gas turbocharger can be closed by one shut-off element each.
