New Mahle piston ring coating for high-output GTDI engines; chromium nitride using high-velocity oxygen fuel process

Green Car Congress

The new top ring coating, also referred to as MSC312, uses chromium nitride applied through a high-velocity oxygen fuel (HVOF) thermal spray process. The market for high-output turbocharged engines is expected to achieve a market share of 30% or more by 2020. Typically high-output engines under 3.5

(Alternatively, in the second study, gasoline–alcohol DFSI is based on PFI of gasoline and DI of alcohols.). However, engine knock with high pressure rise and pressure oscillation caused by end-gas auto-ignition is still the big obstacle for deep improvement of fuel consumption. 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.
