ENGINE WITH VARIABLE STROKE CHARACTERISTICS

摘要

In a variable stroke internal combustion engine, by determining the relationships of a connecting point (D) between a first link (4) and second link (5) and a connecting point (B) between the second link (5) and a control link (12) with respect to a center (A) of a crankpin (9) to be such that ”D < ”B holds over an entire rotational angle of the crankshaft, where ”D is the distance between D and A and ”B is the distance between B and A, an adequate durability of the engine can be ensured without increasing the weight thereof.
