ABSTRACT:
An internal combustion engine with several parallel-connected exhaust gas turbochargers which are adapted to be individually connected and disconnected. The exhaust gas turbochargers are constructed so that together they accommodate the exhaust gas and air mass throughflow of the internal combustion engine at rated power. At a partial power of the internal combustion engine, in correspondence with an instantaneous supply of exhaust gas, such a number of exhaust gas turbochargers are in operation that the internal combustion engine operates maximally close to optimum operating conditions. One of the exhaust gas turbochargers is constructed for a lower exhaust gas and air mass throughflow than the remaining exhaust gas turbochargers. The larger exhaust gas turbochargers are added in succession, corresponding to respective exhaust gas supplies in case of changes during operation of the internal combustion engine toward higher partial power and are disconnected in succession in case of changes toward lower partial power. The small exhaust gas turbocharger, in an operating range between lowest and highest exhaust gas supply of the internal combustion engine, is repeatedly added and repeatedly disconnected in supplementation to the large exhaust gas turbochargers.
