<p>Comprising crank mechanism (29) consisting reduced friction sliding and turning pairs wherein said crank mechanism is provided with at least one lighter mass better dynamic response crankshaft (15) with no/reduced counter weight (21) and/or flywheel (22) mass reducing harmful dynamic forces further lowering frictional force and mechanical loading, at least one air regulating mechanism having equal inlet and outlet port openings communicating with at least one reduced interference and plenum volume manifolds being provided in cylinder head and/or on cylinder, said openings being opened or closed by valves or piston with no/minimum stroke overlap timing events to eliminate harmful dynamic force, reduce pumping force and thereby increase gas force improving gas flow characteristics, at least one fuel regulating mechanism for faster injection of large quantity, shortening auto-ignition being facilitated by lower air compression pressure and fuel injection pressure due to increased air movements.</p> |
