摘要： A piston-crank mechanism links crankpins of a crankshaft with piston pins of pistons by using a plurality of links. The piston-crank mechanism allows an upward inertia force produced near a top dead center of each piston to be smaller than a downward inertia force produced near a bottom dead center of the piston in order to reduce secondary vibration occurring during operation. In a four-cycle inline four-cylinder internal combustion engine, a total force of inertia forces exerted from adjacent cylinders to each of second and fourth crankshaft bearings becomes a downward force, which reinforces a downward force produced in response to combustion pressure. These second and fourth crankshaft bearings have a rigidity higher than the remaining crankshaft bearings.

摘要： A toroidal-type continuously variable transmission (CVT), including rolling elements having traction surfaces cooperating with each other to transmit a power between the rolling elements via a traction oil film formed between the traction surfaces. The traction surfaces have the microstructure that is defined with respect to a thickness of the traction oil film formed when the temperature of the traction portion of the traction surface is high, to thereby exhibit high traction coefficient even in the high-temperature operating condition.

摘要： A multi-link engine has a piston that moves inside a cylinder. A piston pin connects the piston to an upper link, which is connected to a lower link. A crank pin of a crankshaft supports the lower link thereon. The lower link is pivotally connected to one end of a control link, which is connected at another end to the engine block body by a control shaft. The control shaft is lower than a crank journal of the crankshaft, and disposed on a first side of a plane that is parallel to a cylinder center axis and that contains a center rotational axis of the crank journal. The cylinder center axis is located on a second (i.e., opposite the first side) plane. The control link has a center axis that is parallel to the cylinder center axis when the piston is near top and bottom dead centers.
