Internal combustion engine
摘要:
In an internal combustion engine, a piston reciprocating in a cylinder and a crankshaft are linked with each other by a piston-crank linking mechanism. The crankshaft includes a counterweight. When the piston is located in the proximity of a bottom dead center, an outermost portion of the counterweight crosses an imaginary extension line extended from a piston pin in an axial direction of the piston pin.
