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

Green Car Congress

Mahle has developed a new thermal spray coating for modern high-output direct-injection turbocharged gasoline engines (GTDI). The new top ring coating, also referred to as MSC312, uses chromium nitride applied through a high-velocity oxygen fuel (HVOF) thermal spray process. cold gas methods (CGS).

Study finds technology cost of achieving European 2020 LDV CO2 targets more than offset by resultant fuel savings

Green Car Congress

This first report (Phase I) examines only the impact of improving the efficiency of fossil-fueled vehicles, in which efficiency gains are delivered by the improvement of the internal combustion engine vehicle, including lightweighting, engine downsizing and hybridization.

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

From a powertrain frame of reference, Mazda is planning a building block strategy—i.e., the step-by-step introduction of electrification to SKYACTIV internal combustion engines: stop-start, followed by regenerative braking, followed by electric motor drive technologies. Extreme compression ratio rather than downsizing.

2014 Sprinter van for US standard with new 2.1L diesel; new driver assistance features

Green Car Congress

This downsizing enables lower fuel consumption, accompanied by low emissions and optimum weight. The electric fuel pump controls the fuel supply for the Sprinter according to requirements—i.e. Charging takes place at all times via a two-stage exhaust-gas turbocharger system. with a variable delivery rate.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. Combustion stability.

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 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 In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) It is much more than that.
