Abstract
In the operation of supercharged internal combustion engines, certain operating conditions exist during which the exhaust gas turbochargers cannot supply adequate supercharging air for the internal combustion engine due to a low production of exhaust gas by the engine. To eliminate this problem, an auxiliary compressor with a flywheel is proposed, which is constantly driven by an auxiliary drive mechanism and whose power input can be considerably reduced by closing its air conduit. In case of lacking charging air, the auxiliary compressor is used in a simple way, by opening the closure devices on its air side, in order to enable a supply of supercharging air to the internal combustion engine. The power required for driving the auxiliary compressor is derived primarily from energy stored in the revolving flywheel mass as well as from the power of the auxiliary drive mechanism.
