SPLIT-CYCLE ENGINE WITH DWELL PISTON MOTION |
摘要 |
An engine includes a crankshaft having a crank throw, the crankshaft rotatin g about a crankshaft axis. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that t he compression piston reciprocates through an intake stroke and a compression stroke of a four stroke cycle during a single rotation of the crankshaft. An expansion piston is slidably received within an expansion cylinder. A connecting rod is pivotally connected to the expansion piston. A mechanical linkage rotationally connects the crank throw to the connecting rod about a connecting rod/crank throw axis such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke of the four stroke cycle during the same rotation of the crankshaft. A path is established by the mechanical linkage which the connecting rod/crank throw axis travels around the crankshaft axis. The distance between the connecting rod/crank throw axi s and crankshaft axis at any point in the path defines an effective crank thro w radius. The path includes a first transition region from a first effective crank throw radius to a second effective crank throw radius through which th e connecting rod/crank throw axis passes during at least a portion of a combustion event in theexpansion cylinder.
