Investigation of Aerodynamic Performance of a Compact Variable Compressor for Vehicular Turbochargers
In order to install a turbocharger which has wider operating range and higher boost pressure than a current supercharging system to an internal combustion engine (ICE) and a hybrid vehicle (HV), one development focus lies on a variable trim compressor (VTC) which can change passage area upstream a c...

| description | In order to install a turbocharger which has wider operating range and higher boost pressure than a current supercharging system to an internal combustion engine (ICE) and a hybrid vehicle (HV), one development focus lies on a variable trim compressor (VTC) which can change passage area upstream a compressor impeller. In this paper, a new variable geometry device, which was developed from the VTC mechanism proposed by Fujiwara et al. in 2018, is studied. The experimental result clarified the performance enhancement associated with the design concept change and the improvement of trim actuation. In addition, the effect of throat configuration difference on performance was numerically analysed. |
