Tsinghua studies on alcohol-gasoline dual fuel engines show fuel efficiency and particle number benefits

Green Car Congress

In a second paper, also published in Fuel , they systematically compared the stoichiometric alcohol–gasoline and gasoline–alcohol DFSI combustion for engine particle number (PN) reduction (and fuel economy improvement), also using a high compression ratio gasoline engine. They flexibly controlled the PFI to DI fuel ratios.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In References.
