“…Likewise, the customer's desired electric driving experience cannot be achieved in every driving situation. 15 Although the ICE cannot be operated with optimum efficiency at every point due to the mechanical coupling, this can at least be approximated by many gear stages combined with an operating point shift by charging/discharging the battery while driving. The efficiency chain from the ICE to the wheel is significantly shorter compared to the serial concept.…”

The pressure to reduce CO2 and pollutants of internal combustion engine (ICE) powered vehicles is higher than ever. The existing gasoline and diesel engine vehicles face a critical challenge to adjust to these stringent demands. By combining a gasoline like clean fuel with a high efficiency thermodynamic cycle (compression ignition), it is possible to create a powertrain that is clean, both globally and locally, and so breaking the historical trade-off between decreasing CO2 versus pollutants. However, very low vehicle out CO2 cannot be achieved if ICEs are not combined with a hybrid electric powertrain. In this paper, the potential of the gasoline like fuel in compression ignition (GCI) vehicle in combination with hybridization is assessed. Three different hybrid topologies have been theoretically assessed in a first step. Afterwards, the most promising has been deeply analyzed by means of longitudinal vehicle simulation. Here, the corresponding hybrid control strategy is optimized. The battery size has been adjusted as well targeting the optimum capacity when using a HEV instead of a PHEV. The combination of highly efficient GCI engine in combination with such an optimized hybrid topology represents an extreme value regarding CO2 reduction for passenger cars. Such vehicles could contribute largely to the emission targets set for 2030 by the European Commission. In summary, this paper presents engineering solution to comply with future greenhouse gas regulations through advanced engine technology and HEV technology.

The pressure to reduce CO2 and criteria pollutants of internal combustion engines (ICE) powered vehicles is higher than ever. The existing gasoline and diesel engine vehicles face a critical challenge to adjust to these stringent demands. By combining a clean fuel like gasoline with a high efficiency thermodynamic cycle (compression ignition), it is possible to create a powertrain that is clean both globally and locally thus breaking the historical trade-off between decreasing CO2 and reducing criteria pollutants. Recent works have demonstrated the potential of higher reactivity gasoline (HRG) fuels to reduce NOX and particulate emissions simultaneously when used in compression ignition (CI) engines. After performing the engine calibration using Design of Experiment (DoE), tests on a roller bench were conducted on a vehicle adapted to be operated with HRG. The results show 7% CO2 reduction using HRG fuel compared to the baseline diesel vehicle while 17% of CO2 benefit compared to the best in class SI car of equivalent size and power. Furthermore, vehicle simulations were used to assess the potential of the GCI vehicle technology when combined with a hybrid electric architecture. From the HEV simulation study, the 2030 CO2 target was reached by using a 48 V 1 kWh battery, P2 architecture, and recalibration the internal combustion engine and after-treatment system (ATS) while fulfilling the expected new EU’s pollutant emission standards.

Internal combustion engines are constantly developing. Currently, a solution in full development is a hybrid car that has an internal combustion engine propulsion combined with an electrical motor. The electrical motor is powered by a battery which in turn is connected to other electricity suppliers for recharging. Therefore, the aim is to recover the thermal energy from the car, through various solutions, in order to transform it into electricity. Electricity is for the car’s battery as well as for its consumers. After an analysis of the energy balance of the internal combustion engine, it can be seen that the engine energy still has great potential to be transformed into electrical energy through various solutions. Electrical energy can be produced even from braking or other mechanical devices that transform mechanical energy into electrical energy. For example, a co generator of energy hybrid electric turbocharger aims to recover exhaust gas energy and to capitalize it. The turbocharger is connected through a shaft with a generator. Between the compressor wheel and the generator is a speed reducer with a gear ratio of 1:10. This article aims to present the analysis based on the results of the experimental and simulation research of the hybrid turbocharger. The tests were performed using a diesel internal combustion engine with 4 cylinders at a capacity of 1.9 liters. The simulations will be performed using AMESim software developed by Siemens. The main parameters, which are highlighted, are: pressure ratio of the turbocharger, the rotation speed of the turbocharger and the power from the experimental results in relation to time and engine power at 100% load.
