Internal combustion engine with variable compression ratio mechanism |
摘要 |
An internal combustion engine is constructed to include a variable compression ratio mechanism. The mechanism has the following structure. An upper link has one end pivotally connected to a piston pin of a piston of the engine. A lower link is pivotally disposed on a crank pin of a crankshaft of the engine and has one part pivotally connected to the other end of the upper link. A control shaft extends substantially in parallel with the crankshaft. A control link has an end pivotally connected to the other part of the lower link. The other end of the control link is connected to the control shaft through an eccentric bearing structure, so that rotation of the control shaft about its axis induces a pivoting of the lower link about the crank pin varying the stroke of the piston. <IMAGE>
