Multi-link engine

A multi-link engine (100) is provided with an upper link (13), a lower link (14) and a control link (15). The upper link (13) is pivotally connected to a piston (11) by a piston pin (16). The lower link (14) is rotatably mounted on a crankpin (12A) of a crankshaft (12) and connected to the upper lin...

More Information
Summary:A multi-link engine (100) is provided with an upper link (13), a lower link (14) and a control link (15). The upper link (13) is pivotally connected to a piston (11) by a piston pin (16). The lower link (14) is rotatably mounted on a crankpin (12A) of a crankshaft (12) and connected to the upper link (13) by an upper pin (17). The control link (15) is rotatably connected to the lower link (14) by a control pin (18) and pivotally mounted on a pivot portion (21) of a control shaft (20). The links (13, 14, 15) are configured and arranged with respect to each other such that inertia forces of a prescribed second or higher order in terms of an engine rotational speed act on at least the upper link (13) and the control link (15) in a transverse direction of the engine (100) with a sum of leftward inertia forces of the prescribed second or higher order being substantially equal with a sum of rightward inertia forces of the prescribed second or higher order.
