Six-Link Variable-Stroke Engine Mechanisms with One Prismatic Joint
The author determines the distinct mechanisms from Watt and Stephenson’s kinematic chains by assuming all th
joints as revolute joints and later draws the same to get variable stroke engine mechanisms by replacing one revolute joint
with prismatic one. By doing so, the need of throttling or pumping losses may be eliminated and as a result the engine
efficiency may be increased. The paper theme is based on theoretic approach and extremely useful for P.G students, research
scholar and design engineer in the conceptual stage of design of engine mechanisms.
