FEV) a leading developer of advanced powertrain and vehicle technologies, will exhibit a lean burn engineconcept at the SAE 2011 World Congress that has been modified to run on Compressed Natural Gas (CNG). This engine demonstrates a potential near-term solution. FEV Inc., (FEV) —Gary Rogers, FEV, Inc. Resources.
Motiv Engines, LLC introduced the second-generation of its engineconcept dubbed the MkII Clarke-Brayton Engine, which it intends to develop into a heavy-duty on-highway engine fueled by liquid natural gas (LNG). It expands all the way to ambient pressure before the exhaust stroke.
A cryogenic engine such as the Dearman piston engine produces zero emissions at the point of use; has low greenhouse gas emissions provided the liquid air or nitrogen is produced from low carbon electricity; has energy and power density on a level with battery electric technology; and has the potential for rapid refueling.
The combination of discrete, asymmetrically sized cylinders and fully variable valvetrain promises the ability to vary displacement ratios, bore-stroke ratios, compression-expansion ratios, compression-expansion phasing, and gas transfer phasing for engine optimization—i.e., a more efficient internal combustion engine.
This new funding opportunity announcement will be available in early February. Area of Interest (AOI) 6: Electric Drive Vehicular Battery Modeling for Commercially Available Software. Battery models for this technical AOI will be made freely available to the public for battery pack design and analysis.
This means we have a responsibility to implement emission-lowering solutions available today while simultaneously developing solutions for tomorrow. EPS said that the partnership is an example of different industry players with aligned values coming together to lower greenhouse gas emissions. —Cyril Ducau, EPS CEO.
HCCI is a combustion regime in which well-mixed fuel, exhaust gas and air are compressed to the point of auto-ignition. Unlike a spark ignition gasengine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber. Elements of the Grail Engine.
Portable generators based on Libertine’s technology show a saving of up to 80% in package size and weight compared to the most efficient systems currently available. ConceptEnginesEngines' In addition, it is simpler and is easily scaled to suit applications from 1 kW e to more than 100 kW e. —Sam Cockerill.
