FEV to show compressed natural gas light-duty concept engine with ATAC combustion system at 2011 SAE World Congress

Green Car Congress

The compression ratio is adjusted so that it falls between a diesel and a gasoline engine compression ratio, resulting in higher combustion efficiencies. In addition to the design of new components, FEV considered the increased strain on various components, such as valves and valve seats.

Australian Cam-Drive Gasoline Engine Reaches 39.5% Efficiency in Independent Testing; Potential for Production Engine in China

Green Car Congress

Australia-based Revetec is designing what it calls the Controlled Combustion Engine (CCE)—a cam-drive gasoline spark-ignited internal combustion engine that is smaller, lighter, cleaner, less expensive to manufacture and that produces higher torque due to higher mechanical transfer than equivalent conventional engines.

Start-up Eco-Motive developing dual-fuel “H” engine; parallel, independently fueled piston banks

Green Car Congress

The H-engine—basically two separate engines housed within the same engine block—comprises two switchable parallel piston banks, independently fueled by gasoline and CNG. Startup Eco-Motive has developed what it calls the first dual-fuel “H” engine; it recently received a patent (# 8807098 ) on the design.
