HPDI concept

  • High pressure gas injection engine devlopment and vehicle integration
  • Emission compliance Euro VI achieved
  • -20% GHG achieved
  • 800km range achieved
  • >90% substitution rate (GER) achieved

The HDGAS Volvo concept features high pressure direct injection of natural gas into the combustion chamber and requires pressure level of approx. 300 bar.

Other Development Goals (all achieved):

  • Efficiency comparabel to state of the art diesel
  • Negligible EO soot emissions
  • CH4 < Euro VI without Methane-aftertreatment

Technologies used:

  • LNG tank
  • High pressure LNG pump
  • Common rail diesel pump
  • Dual media injector
