High Performance Computing key enabler for accelerating development of high efficiency engines

Green Car Congress

Next-generation engines will likely operate at higher pressures, with greater amounts of dilution and utilize alternative fuels that exhibit a wide range of chemical and physical properties. Achievable advances in engine technology can improve the fuel economy of automobiles by over 50% and trucks by over 30%.
