ABSTRACT:
A simple and inexpensive method for converting an N-cylinder automobile engine to an (N/2)-cylinder engine which requires only minor modifications to the basic engine structure. Every other cylinder in the firing order is deactivated by removing adjacent spark plugs. A conduit is connected between the spark plug hole for each such cylinder and the carburetor air cleaner to prevent power stroke vacuum, exhaust stroke compression, and passage of debris. The rocker arm assemblies for each deactivated cylinder are removed to maintain the intake and exhaust valves in a closed position, and thereby discontinue fuel flow and limit the air flow to that through the conduits.
