Title:
THREE-DIVIDED CONNECTING ROD TYPE STROKE VOLUME AND COMPRESSION RATIO CONTINUOUS VARIABLE DEVICE
Document Type and Number:
Japanese Patent JP2019167945
Kind Code:
A
Abstract:
To provide a compression ratio continuous variable device in which crank angles between a top dead center and a bottom dead center and between a bottom dead center and a top dead center are kept constant and crank phases of the top dead center and the bottom dead center are not changed in the entire range of a continuously variable compression ratio.SOLUTION: A connecting rod cooperatively connecting a piston with a crank is divided into three types of a piston connecting rod, a crank connecting rod and a link oscillatably connecting them in a direction perpendicular to a crank journal shaft, an oscillation shaft of an oscillation arm for stroking a small end of the crank connecting rod in a circular arc-shaped manner is fixed and an oscillation shaft position of the oscillation arm for stroking a large end of the piston connecting rod in a circular arc-shaped manner is variably controlled in a two-dimensional manner.SELECTED DRAWING: Figure 1
