TDK and Toshiba establish JV for automotive inverters for HEVs, PHEVs, EVs

Green Car Congress

Many countries propose to impose more stringent regulation of automobile exhaust emissions in 2020 and after, in an effort to prevent air pollution and global warming. TDK offers a lineup of products, such as DC-DC converters, on board chargers and wireless power transfer systems that are currently being developed.

NREL announces $18M investment in 9 new projects to advance medium- and heavy-duty natural gas vehicle technologies

Green Car Congress

will address natural gas engine emissions and efficiency improvements by developing a natural gas specific combustion design utilizing optimized in-cylinder charge motion and cooled exhaust gas recirculation (EGR). The engine will be integrated on a global heavy-duty base engine platform, enabling up to a 20% system cost reduction.

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component. Standard deviations increase by >10% and >200% when used in high and low blends, respectively.

SwRI simulations indicate Scuderi split-cycle engine consumes 25% less fuel than comparable conventional engine in Cavalier; 36% reduction with hybrid configuration

Green Car Congress

The Scuderi engine divides the four strokes of a combustion cycle among two paired cylinders—the left cylinder functions as an air compressor, handling intake and compression, while the right cylinder handles combustion and exhaust. With turbocharging, we can have some huge gains, we can downsize the engine and produce very big power.

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. Globally, billions of people are using this ancient grid as installed, but the enormous potential of the grid is untapped—we could be getting much more energy from it. by Professor Andrew Alfonso Frank.
