ABSTRACT:
An internal combustion engine having one or more compounded pairs of undulating volumes, such as produced by a piston reciprocating within a cylinder or tri-shaped rotor orbiting within an epitrochordial shaped chamber, hereinafter referred to for convenience as cylinders. A total of eight cycles or "events" occur withiin paired cylinders which are located side-by-side in as close proximity as possible so as to share periodically common combustion and provided with combustible fuel mixtures prepared externally of the combustion chamber through conventional means, such as carburetion or jet systems. The fuel-air mixture, when involving a petroleum type fuel, is positively programmed to be burned internally in two stages, the first burn at elevated temperatures is a fuel-rich, oxygen-lean mixture to minimize the nitrous oxides produced, and the second burn at lower temperatures is a fuel-lean, oxygen-rich mixture to substantially complete combustion of unburned hydrocarbons and oxidize carbon monoxide prior to being exhausted to the atmosphere. To thus divide the combustion, the mixtures are not solely dependent upon stratified fluidic charges within each cylinder, but paired cylinders communicate to form a common combustion chamber to effect the second stage burn and extended power expansion by differential displacement. Both cylinders have inlet valves, only the second stage having an exhaust, a movable valve also being provided to allow communication between the cylinders at specific times during operation.
