Multi-link engine |
摘要 |
A multi-link engine has a piston coupled to a crankshaft to move inside an engine cylinder. A piston pin connects the piston to an upper link, which is connected to a lower link by an upper link pin. A crank pin of the crankshaft rotatably supports the lower link thereon. A control link pin connects the lower link to one end of a control link, which is connected at another end to the engine block body by a control shaft. The upper link has an upper link axis that forms an angle with the cylinder axis, as viewed along a crank axis direction of the crankshaft, such that the angle reaches a minimum when a crank angle of the engine is within a range where the bottom end of a piston skirt is positioned below a topmost part of the bottom end of the cylinder liner. |
