摘要： An internal combustion engines keeps the pistons at or near the Top Dead Center (TDC) for the whole time or most of the time that fuel is burning or while fuel is injected into the engine. A scotch yoke embodiment includes a curved slot to extend the piston's time at TDC. A second embodiment includes a cam on the crankshaft and a follower. The shape of the cam extends the piston's time at TDC.

摘要： A rear drive axle assembly includes fixedly attaching right and left axles to right and left rear wheels. Inner ends of the axles residing in a tube and reach in to almost a center of the vehicle, and extend out through self-aligning, pillow block bearings. Sprockets are attached to the axles between outer ends of the tube and the pillow block bearings. Negligible friction between the axles and tube is the only rotational coupling of the axles. The Rigid Tube provides concentricity between the two axles, provides perpendicularity of the drive wheels to the road surface and performs the function of a sleeve bearing.

摘要： An internal combustion engines keeps the pistons at or near the End Of Stroke (EOS) for the whole time or most of the time that fuel is burning or while fuel is injected into the engine. A scotch yoke embodiment includes a curved slot to extend the piston's time at (EOS). A second embodiment includes a cam on the crankshaft and a follower. The shape of the cam extends the piston's time at (EOS).
