MULTI-LINK PISTON-CRANK MECHANISM FOR INTERNAL COMBUSTION ENGINE |
摘要 |
When the compression ratio of a variable compression ratio internal combustion engine (10) is set at a low compression ratio, a lubricating oil ejected from a lower link oil passage (25) is reflected by an upper link (11) at the piston top dead center, and supplied to a cylinder inside wall surface on the side on which a control link (15) is located in a view as viewed in the axial direction of the crank shaft. When the compression ratio of the variable compression ratio internal combustion engine (10) is set at a high compression ratio, the lubricating oil ejected from lower link oil passage (25) is reflected by upper link (11) at the piston top dead center, and supplied to the back side of the piston crown. |
