Title:
DEVICE FOR CONTINUOUSLY CHANGING STROKE VOLUME AND COMPRESSION RATE WITH INTERNAL ANGLE OF CYLINDER CORE SHAFT AND CONNECTING ROD SMALL END LOCUS SET TO ACUTE ANGLE
Document Type and Number:
Japanese Patent JP2022037838
Kind Code:
A
Abstract:
To provide a device for continuously changing a stroke volume and a compression rate, which is compact and can reduce vibration over the entire range of use.SOLUTION: In a device in which a piston 11 and a crank shaft 15 are connected with three links, at a top dead center, with an internal angle of a line linearly connecting a connecting rod small end axis CSb, a crank pin axis CSt and a crank journal axis Oj, and a cylinder core axis Y set to an acute angle. a connecting rod small end is stroked linearly with a guide rail or in an arc manner with an arm, and a position of a swing axis of a variable control arm with the swing axis arranged on the opposite side of a crank with respect to the cylinder core axis Y is changed, so that a stroke locus at a piston rod large end is changed to continuously change a stroke volume and a compression rate.SELECTED DRAWING: Figure 1
