Abstract
This invention has two main embodiments. An opposed piston 2-stroke axial engine and a 4-stroke axial engine. The opposed piston two stroke also offers an option of a novel cylinder deactivation design. Both, two stroke and four stroke engines share novel systems for coupling piston reciprocation to shaft rotation, piston and piston ring lubricant distribution, and provision for reacting out piston side load with minimum mechanical friction.
Claims16
An opposed piston two stroke axial engine wherein a piston assembly engages a cam with a plurality of primary rollers in order to spread contact loads and reduce roller to cam slippage, a plurality of provisions to react out piston side loads with a plurality of roller element bearings, and a piston anti-rotation feature using the plurality of roller element bearings, wherein the opposed piston two stroke axial engine has a piston cavity and a sliding oil supply tube to supply oil to the plurality of primary rollers.
An opposed piston two stroke axial engine wherein a piston assembly engages a cam with a plurality of primary rollers in order to spread contact loads and reduce roller to cam slippage, a plurality of provisions to react out piston side loads with a plurality of roller element bearings, the opposed piston two stroke axial engine having a sliding oil supply and annular groove, the opposed piston two stroke axial engine having a liner piston skirt and a plurality of rings wherein oil is suppliable from the sliding oil supply to the liner piston skirt and the plurality of rings.
An opposed piston two stroke axial engine wherein a piston assembly engages a cam with a plurality of primary rollers in order to spread contact loads and reduce roller to cam slippage, a plurality of provisions to react out piston side loads with a plurality of roller element bearings, the opposed piston two stroke axial engine having an oil supply system with a spring loaded oil delivery head on a piston skirt.
An opposed piston two stroke axial engine wherein a piston assembly engages a cam with a primary roller in order to spread contact loads and reduce roller to cam slippage, a plurality of provisions to react out piston side loads with a plurality of roller element bearings, wherein the opposed piston two stroke axial engine has an oil delivery system with an oil delivery slider that is spring loaded against a piston oil delivery groove by an oil delivery pipe, wherein the oil delivery slider is movable with respect to the oil delivery pipe.
