TWO-PIECE HOUSING CONNECTING ROD L-SHAPED YOKE TYPE CYLINDER CAPACITY CONTINUOUS VARIABLE DEVICE WITH PISTON TOP DEAD CENTER AND BOTTOM DEAD CENTER AND COMPRESSION RATIO LIMITER

摘要

PROBLEM TO BE SOLVED: To eliminate a default that although there is provided a device for changing an arm oscillation shaft position to restrict a motion of a connecting shaft of two-piece housing and connected and for continuously varying its stroke, this device was not a cylinder capacity and compression ratio continuous variable device showing a small amount of its top dead center phase during variable time and capable of substantially reducing a piston side pressure and also restricting the piston top dead center and the piston bottom dead center as well as a range of compression ratio.;SOLUTION: One of the two-piece housing connecting rods is applied as L-shaped yoke, a connecting rod connecting shaft core is arranged in a range where it is arranged on an extended line of an arm oscillation and connecting shaft core from a position on vertical line passing through the connecting shaft core in respect to a side connecting a crank pin with a variable control arm connecting shaft at the time of maximum oscillation of the arm top dead center side where an arm oscillation arranging center at any one of minimum or maximum stroke capacity is near a right angle in respect to a cylinder axis, the arm connecting shaft is oscillated by the arm in an arcuate state, the arm oscillation shaft position is variably controlled in a two-dimentional manner in such a way that its locus approaches at a side spaced apart from a crank journal shaft core and its position and angle are changed in a range of a shape of lower spread shape where it is wide spread at both sides and then a journal shaft is arranged in the shape of lower spread shape.;SELECTED DRAWING: Figure 1-1;COPYRIGHT: (C)2018,JPO&INPIT
