摘要： PROBLEM TO BE SOLVED: To prevent a corner-shaped lower edge part 26 of a cylinder 11 from being brought into contact with a piston 12 by so setting that a part of the piston 12 lowers more than the lower edge part 26 of the cylinder near the bottom dead center of the piston. SOLUTION: The lower end of an upper link 14 connected to the piston 12 is connected to a lower link 17 attached to a crank pin 16 through an upper pin 15. The gravity center 12A of the piston is offset from the center 13A of the piston pin in the thrust-antithrust direction. At least near the bottom dead center of the piston, the upper pin 15 is offset from the center 13A of the piston pin to the anti-piston gravity center side R to bring the upper part of the piston on the piston gravity center side L into contact with the wall surface of the cylinder 11.

摘要： PROBLEM TO BE SOLVED: To suppress the overall height of an internal combustion engine when inclining a cylinder axis, especially when composing a V type eight cylinder internal combustion engine having a bank angle of 90°.
SOLUTION: In this internal combustion engine provided with an upper link 9 connected to the piston pin 10 of a piston 11, a lower link 4 connecting the upper link 9 and the crank pin 3 of a crankshaft 1 to each other, and a control link 6 with one end 7 swingably supported to an engine body side and the other end connected to the lower link 4, the center of oscillation of the control link 6 to an engine body is set to a side opposite to the piston 11 to the rotational center of the crankshaft 1 in the vicinity of a line passed through the rotational center of the crankshaft 1 and parallel to a piston reciprocating direction. Thereby, when the internal combustion is slantly installed, the overall height of the internal combustion engine is lowered.

摘要： PROBLEM TO BE SOLVED: To solve the problem that, when the antiresonance frequency of a vibration system corresponds to a given frequency, great vibration reducing effects are obtained near the antiresonance frequency but vibration is in turn increased near a resonance frequency.
SOLUTION: To vary an equivalent moment of inertia of a subsidiary inertial mass against the rotation of the rotating shaft of an engine corresponding to the rotating speed of the rotating shaft, an electromagnetic clutch 17 is provided for cutting an alternator rotor 15 as the subsidiary inertial mass off a pulley 4a. At an idling rotation speed, the vibration is reduced by the antiresonance of the vibration system including the subsidiary internal mass. In a resonant rotation speed region, the resonance is avoided by cutting the electromagnetic clutch 17 off.
