Variable compression ratio mechanism of reciprocating internal combustion engine |
摘要 |
<p>A variable compression ratio mechanism of a reciprocating engine includes at least an upper link connected at one end to a piston pin and a lower link connecting the other end of the upper link to a crankpin. At top dead center, when, of hypothetical connecting points between the upper and lower links, to be able to be supposed on both sides of a line segment connecting a piston-pin center and a crankpin center, a first one of the connecting points has a smaller inclination angle measured in the same direction as a direction of rotation of the crankshaft from an axial line of reciprocating motion of the piston-pin center and formed between a line segment connecting the piston-pin center and the first connecting point as compared to the second connecting point, the first connecting point is selected as an actual connecting point. <IMAGE></p> |
