Document Type and Number:
Japanese Patent JP4206219
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase an output torque by heightening intake inertia effects of an internal combustion engine. SOLUTION: A connecting means 29 for connecting a piston 14 to a crankshaft 20 comprises a first connecting rod 22, whose both ends are pivotally supported by a piston pin 21 and an intermediate pin 23, a second connecting rod 24, whose both ends are pivotally supported by the intermediate pin 23 and a crank pin 25, and a link arm 26, whose both ends are pivotally supported by the intermediate pin 23 and a fixing part 27 that is positioned below the crankshaft 20. When the piston 14 is placed at a top dead center, the first connecting rod 22 is placed approximately along an axial line L2 of the cylinder 13, and the second connecting rod 24 is approximately perpendicular to the axial line L2. As a result, a descending time of the piston 14 becomes shorter than an ascending time of the piston, and an intake flow rate is heightened during a suction stroke in a low-speed rotation area, to show intake inertia effects. Thereby, intake efficiency is heightened to improve output.
