    In recent years, with the great efforts toward carbon neutrality as a measure against global warming, it is predicted that the share of hybrid electric passenger cars will increase. The operating range of internal combustion engines for hybrid electric vehicles is limited compared with conventional ones and turbochargers are also required to be developed to address this limitation. Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. (MHIET) has developed high-efficiency compressors that meet the requirement of hybrid electric vehicles, vaned nozzle turbines designed for higher efficiency, ball bearings designed to reduce mechanical loss and low-cost turbine housing materials that are designed by using data science and has been proposing to automobile manufacturers.
