ABSTRACT:
A system is disclosed for use in connection with a conventional Otto or four cycle, multi-cylinder, internal combustion engine with the system being adapted to selectively disable half of the operating cylinders of the engine whereby substantial fuel economies can be realized. The present system is adapted to be used as an attachment on a conventional automotive engine and is equally applicable to four, six, and eight cylinder engines. The system disables selected cylinders by both inhibiting flow of fuel to the cylinder and disabling the exhaust valve in an open condition so that the disabled cylinder will, in effect, be free wheeling in that it does not use fuel or produce unused compression which must be overcome by the remaining cylinders.
