This paper presents the characteristics of a Variable- Radius/Length engine (V-R/L engine) which has an eccentric on the connecting rod big end. This is intended to improve the power output of short-stroke multi-valve engines. The V-R/L engine makes it possible to improve power output through high volumetric efficiency and to delay the ignition timing for best torque (MBT) through refined combustion-chamber shape. However, more improvements are required to apply the mechanism to high-speed engines because of increased friction losses.
