AN INVESTIGATION OF THE EFFECTS OF INTAKE VALVE LIFT ON THE PERFORMANCE IN SPARK IGNITION ENGINES

Abstract

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.
