The first registrant in the Challenge is Libralato Engines, developer of a novel rotary engine (cutaway shown) promising a 5.5% gain in combustion efficiency and 50% reduction in NO x emissions. Rotor 1, Rotor 2 and the connecting cam form the total internal mechanism of the engine. Click to enlarge.

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.

Thermochemical exhaust heat recuperation (TCR) in an internal combustion engine could result in substantial boosts in second-law efficiency (as measured in terms of single-stage work output from an ideal IC engine) for a range of fuels, according to a new study by researchers at Oak Ridge National Laboratory (ORNL).
