Evaluation of an electric turbo compound system for SI engines: A numerical approach

Abstract: In a medium term scenario hybrid powertrain and Internal Combustion Engine (ICE) downsizing represent the actual trend in vehicle technology to reduce fuel consumption and CO2 emission. Concerning downsizing concept, to maintain a reasonable power level in small engines, the application of turbocharging is mandatory both for spark ignited (SI) and compression ignited (CI) engines. Following this aspect, the possibility to couple an electric drive to the turbocharger (electric turbo compound) to recover the res… Show more

“…Various works focus on thermal and mechanical losses of turbochargers [31,32]. Other works focus on turbine coupling with the ICE which has an outflow characterized by cyclic variation in amplitude [31,33]. These studies show that the energy provided to the turbine is higher than the amount of energy evaluated taking into account the average pressure values before and after the turbine.…”

“…Utilizando a configuração integrada para extrair potência elétrica, os autores [15] conseguiram obter até 10% de economia de combustível, com média e alta cargas, em rotações elevadas num motor Diesel. Para a mesma configuração, mas com motor a gasolina, autores [16] obtiveram até 4% de redução no consumo de combustível, dependendo das condições de operação do veículo e ressaltando, ainda, que para veículos de passeio pequenos e em ciclos urbanos os ganhos são pequenos, mas que para veículos grandes e em autoestradas, os ganhos de eficiência e consumo de combustível são consideráveis.…”

“…Compared with other electrically assisted boosting systems, the ETA can achieve higher fuel efficiency than the electric supercharger [5]- [7] and electric turbocompounding [8]- [10]. The electric supercharger and the turbocharger work as a twostage system, with the EM and compressor connected in series.…”
