Water injection for charge cooling

Downsizing direct injection gasoline engines at elevated power density involves several challenges of engine design. Recently water injection has been re-discovered to have a high potential to deliver a feasible solution between several trade-offs. Water injection also leads to charge cooling allowing for higher compression ratios.

of Charge Cooling
  • Better knock resistance
  • Lower particulate (PM) and NOx emissions
  • Higher maximum power and torque
  • Improved component protection
