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. Overview of the Libralato Engine.

Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber. HCCI combustion can deliver a very efficient engine, potentially providing a 20% to 30% boost in gasoline engine efficiency without the NO x or PM emissions of a diesel.

Although the HPE approach can in concept be applied to both spark ignition (SI) and compression ignition engines (CI), after an evaluation of engine types, the team decided that downsized SI engines offered the best target for an HPE application. The concept engine uses the Bosch electro-hydraulic valve system (EHVS).

High-pressure air jet controlled compression ignition (JCCI) is based on a compound thermodynamic cycle and is implemented in a hybrid pneumatic engine (HPE) as proposed by Schechter in 1999. The application of HPE is also beneficial to the fuel consumption and emissions because of its several flexible operation modes.
