Variable compression ratio engine

摘要: PROBLEM TO BE SOLVED: To provide a variable compression ratio engine simply formed in structure, capable of easily securing sealing performance, and having high reliability. SOLUTION: In this engine, connecting rod 13 converting the vertical movement piston 6 cylinder 5 to rotating motion crankshaft 14 is divided at least two pieces, control 21 connected part or near so that pivot position can be displaced. The right side 28 reciprocatingly moving hydraulic 27 double type linked 35 moved according displacement 21. Two pressure chambers 43 44 demarcated by are each other through flow passage oil selectively supplied from chamber left stopped. COPYRIGHT: (C)2005,JPO&NCIPI
