Abstract
A rotary internal combustion engine is disclosed having circumferential type cooling circuit for the rotor housing and a plurality of spark plugs extending through the trochoid wall of the rotor housing at a vertically rising zone of said circuit. The plugs are contained by bosses extending through the coolant flow passage; the bosses are arranged to stagger the up-stream sides of said bosses with respect to controlled flow of coolant thereabout, thereby increasing flow control, increasing heat transfer, and preventing a collection of vapor which may act as an insulation film hindering heat transfer between said bosses and coolant flow. The centerline of said bosses are preferably skewed with respect to both a plane bisecting the flow longitudinally and a plane bisecting the flow transversely, whereby the spark terminals of said plugs may be maintained within narrow offset limits on opposite sides of a centerline of the gas side of said trochoid wall.
