A twin cam engine with separate camshafts for inlet and exhaust valve operation provides the possibility of altering the relative angular position of the two camshafts on the running engine (variable overlap) and thereby achieving better engine torque characteristics, improved part load fuel consumption and also reduced emissionsThis paper presents the Test Results of changing the Valve Timing and Valve Overlap and describes the concept of a prototype twin cam engine with programmed computer controlled variable overlap.
