In this study, the effects of intake valve lift variation on engine performance have been investigated experimentally. An alternative prototype has been designed and constructed for variable valve systems. A fourstroke, single cylinder, spark ignition engine has been used for experiments. The effects of four different intake valve lift value (6.5 mm, 5 mm, 4 mm and 3 mm) on volumetric efficiency, engine torque, specific fuel consumption and exhaust emissions have been investigated.
