Internal combustion engines have an efficiency of operating which can be exploit to increase its performance. Part of the residual gases can be recovered through the technical solutions such as turbocharger. The turbocharger solution is one of the most popular technical solutions for increasing the energy performance of internal combustion engines. The turbocharger can contribute also with new technical solutions to increase the energy performance of the internal combustion engines. One of the solutions proposed for the theoretical and experimental research is the hybrid turbocharger, which has a double function, namely to compress the fresh air for the internal combustion engine, and to generate electric energy for the electric engine of the vehicle both for consumption and for to be stored in batteries. This article aims is to present new solutions for increasing the energy performance of internal combustion engines and to demonstrate the efficiency of the new solutions such as a hybrid turbocharger through calculations and simulation using the AMESim software.
