RECIPROCATING PISTON TYPE ENGINE

摘要

PROBLEM TO BE SOLVED: To easily and inexpensively make an offset crank mechanism for practical use. SOLUTION: A cylinder bore is formed in a cylinder block so that the upper end side inclines to the left side with respect to a vertical line LN1 in a state of passing the center line CL of the cylinder bore through an intersection between a mating face SL and the vertical line LN1 passing through the center O of a crankshaft 21. In this case, a cylinder is set to the so-called long stroke of being longer in a piston stroke ST than a cylinder bore diameter D. COPYRIGHT: (C)2007,JPO&INPIT
