Abstract: A combustion engine comprising a lubricated bearing mountable on the shaft of the engine, and a race/seal bearing plug engagable therewith and engagable with a housing member of the engine. The race/seal bearing plug comprises lubricant passage therein dispensing lubricant medium to the bearing, with the bearing discharging lubricant to a lubricant slinger which serves to centrifugally direct the lubricant to a peripheral collection channel for recirculation to the lubricant flow passages in the bearing plug.

Abstract: A rotary engine having a rotor mounted in an engine block for rotation and operable for rotation in either of opposing rotational directions. In one aspect, the rotary engine comprises an oil slinger concurrently rotatable to centrifugally disperse lubricants to interior surfaces of the engine block and rotor. In another aspect, the rotor may utilize a swept-back saw-toothed configuration or a cruciform arcuate shape. The rotary engine of the invention can be provided as a plurality of engine modules which are operatively interconnected to form a power train of desired size and capacity.
