Engine Burns Its Carbon Monoxide

Elimination of deadly carbon monoxide from exhaust gas is claimed for a new gasoline engine of radical design. Half of the cylinders and pistons in the new engine are larger than the other half; and the number of spark plugs, valves and intake and exhaust manifold openings is half that of an ordinary engine having the same number of cylinders. The inventor, G.A. Bartholomew, of Cleveland Ohio, uses a principle similar to that of compound steam engines. Only the small cylinders have spark plugs for ignition. When the explosion in the small cylinder is almost over, the hot gases produced pass through a valve into the adjacent large cylinder, and are mixed with fresh air. Here they continue burning, using up all carbon monoxide, and producing additional power with a reduction in fuel consumption.
