AB Engine Incorporated introduces a New Method (AB Engine Method) to convert burning gasoline, gas or diesel fuels into mechanical energy while still within the bounds of the conventional Otto, Miller, Diesel or similar internal combustion engine (ICE) design constraints. The new method allows for an ICE design with the highest efficiency of fuel consumption theoretically possible. In February 2012, AB Engine Inc. announced that it has designed and completed a high efficiency internal combustion engine (ICE) prototype in order to demonstrate the "proof of principles" behind the AB Engine Technology delivering 45% higher fuel efficiency compare to identical conventional engine.
