This project presents the spring less valve system used in the IC engines. Unlike the conventional valve system spring less valve system uses two cams for each valve with absence of spring. This mechanism has a closing cam which does not allow cam jump as conventional valve system. In this work first we are going to discuss conventional valve mechanism and its advantages and disadvantages and then we are going to discuss about spring less valve system along with its advantages and disadvantages. It will help us to find out how spring less valve system is better than conventional valve system. We are also going to find out the real importance of this spring less system at higher rpm of engine and need of this system at higher rpm. This system improves the performance of IC engine by reducing power consumption for overcoming spring stiffness and avoid cam jump at high speed.
