Design optimization of cam and roller follower for improving efficiency of an I.C engine

Abstract

The existing cams used in internal combustion engines are made in a variety of forms which have a line contact with follower. As line contact between current cam and follower mechanism results in high frictional losses which results in low mechanical efficiency. Hence in this work an attempt is made to change the flat face of follower by using optimization technique, so that the required length of contact is reduced near about to point contact can be achieved to minimize frictional losses and the efficiency of the cam and roller follower will be improve.
