| Summary: | The main objective of this work is to perform an extensive study on the causes of the torque dip in CAMPRO engine and subsequently to provide the best solution that will
improve the performance, reliability as well as production cost. CAMPRO engine is a basic Double Overhead Camshaft (DOHC) which has a capacity of 1597 cc and installed with a total of 16 valves developed by Malaysian car manufacturer PROTON in the year 2000.The CAMPRO engine experiences performance downfall when it reaches at certain rpm. The phenomenon is known as torque dip or torque loss where
the output torque is not smooth, consequently formed a dip in the torque curve. The dip which occurs at 2500 – 3500 rpm is mainly influenced by the geometry of the designed
intake manifold and valve timing. Analysis is mostly confined on the intake manifold geometry and the valve timing. Two possible solutions viz., dual length intake manifold and variable valve timing are analyzed. |
