Goal
Eliminate carbon monoxide from exhaust and reduce fuel consumption
Problem
Deadly carbon monoxide emissions and inefficient fuel use in gasoline engines
Concept Summary
The engine uses a compound-engine principle: small cylinders ignite the fuel-air mixture, then near the end of combustion the hot gases are transferred through a valve into adjacent larger cylinders where they mix with fresh air and continue burning, fully oxidising CO and producing additional power.
Detailed Description
Only the small cylinders have spark plugs. After the primary combustion, a valve opens and the hot gases flow into a larger cylinder that contains only air. In the larger cylinder the gases complete combustion of any remaining carbon monoxide, extracting extra work and reducing the amount of CO in the exhaust. The design halves the number of spark plugs, valves and manifold openings compared with a conventional engine of the same cylinder count.
