New Technical Solution for Hybrid Turbochargers

Abstract 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 turbocharging. The turbocharging solution is one of the most popular technical solutions for increasing the energy performance of internal combustion engines. For the turbocharging process it is used a turbocharger. 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 other to be stored in batteries. This article aims is to present the result of the experimental research of the hybrid turbocharger, simulate and validate the new solutions for increasing the energy performance of internal combustion engines through hybrid turbochargers using a coupled electric generator. The simulations will be made using the AMESim Sofware developed by Siemens to demonstrate the efficiency of the new solutions such as a hybrid turbocharger through calculations. The tests will be carried out with the test bed CIMAT. CIMAT test bed is a machine which provides higt pressure air which simulate the combustion gases of an engine. The pourpose of the CIMAT test bed is to rotate the hybrid turbocharger turbine and also the compressor wheel. More technical information about the hybrid turbocharger test will be presented in the article and also constructive details. Based on the technical information and input data in the first phase it will be made an application for the simulation and validation of the prototype to demonstrate the great potential of the turbocharger to produce also green energy.
