U Wisconsin team investigates RCCI and GCI in single engine using adaptive dual-fuel injector

Green Car Congress

Researchers at the University of Wisconsin-Madison have investigated blending the benefits of reactivity controlled compression ignition (RCCI) and gasoline compression ignition (GCI) using QuantLogic’s novel adaptive dual-fuel injector which is capable of direct injecting both gasoline and diesel fuel in a single cycle.

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

The dual-fuel PCCI strategy showed thermal efficiency of 53%. Emissions under the dual-fuel concept, at 11 bar IMEP. The University of Wisconsin concept proposes the use of dual fuel tanks, with port fuel injection of gasoline and direct injection of diesel, with the in-cylinder mixing of the fuels.
