Delayed drop power stroke internal combustion engine
This patent describes an engine comprising a block assembly, a rotatable crankshaft mounted to the block assembly. It comprises: a driveshaft, crankarm(s) and crankarm pin, a stationary ring gear concentric with the axis of the driveshaft and rigidly attached to the block assembly, a rotatable pinion gear mounted concentrically on the crankarm pin, a rotatable eccentric mounted on the crankarm pin and rigidly attached to the pinion gear, a cylinder having a central axis, a piston reciprocating in the cylinder, a connecting rod with one end rotatably mounted to the piston by a wristpin and the other end rotatably mounted on the eccentric by a rod end cap, were the gears and eccentric comprises a means for decreasing the combustion chamber volume available to the cylinder gases that drive the piston as the piston approaches and passes the minimum volume position during the combustion phase of the engine cycle.cycle.
