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.

Human Need

In order to reducing emission of internal combustion engines and reducing fuel consumption nowadays, human try to discover efficient internal combustion engines and green engines to protect environment. From last years, there were technologies like turbocharger, hybrid electric and different ways of fuel injection into engine and some others that those were effective in that time. By developing technology human need more efficient engine than past. Also, those technologies have some drawbacks so necessity of new technology is sensible. The new technology that developed by EPA (Environmental Protection Agency). HHVs are hybrid vehicle that use pressurized fluid instead of electric power as alternative power source along with internal combustion engine. Hybrid hydraulic vehicles consist of two important part high pressure hydraulic fluid vessels called accumulators, and hydraulic drive pump/motors. These types of vehicles do not need batteries that use in electric vehicle and it is one of expensive part of HEVs.

Technical Requirements

Service and repair of operating and servicing organizations are largely equipped with outdated, low-power, highly specialized bench equipment from former specialized enterprises and do not always meet the technical requirements of the manufacturer, especially for conducting quality control programs for the repair of powerful and modern tractors. These circumstances together reduce the reliability of the obtained diagnostic parameters and may lead to the risk of errors in determining the technical readiness of the repaired equipment, in particular, internal combustion engines, transmission units and chassis, hydraulic drive. (Research purpose) The research purpose is in developing a mobile control and diagnostic device for monitoring the power and fuel consumption of the internal combustion engine, as well as the quality of repair of hydrostatic transmission and hydraulic drive units. (Materials and methods) The article presents an analysis of scientific works on improving methods for diagnosing energy indicators of mobile agricultural machinery, as well as conducted extensive research on the use of axial plunger pumps and throttling the flow of liquid injected by them with a constant and variable cross-section throttle for engine braking. (Results and discussion) Authors developed an experimental model of a mobile control and diagnostic device and experimentally tested the methods for determining its parameters and control and diagnostic operations. (Conclusions) The use of the proposed mobile control and diagnostic device will eliminate excessive fuel consumption by tractors when reducing the effective power of their internal combustion engines below the permissible limits, and will also allow the diagnosis of hydrostatic transmission units in the conditions of agricultural and service enterprises and exclude the sending of serviceable units with unused resources for repair.
