A valve train is an important part of both diesel and petrol engines as they control the opening and closing of valves and greatly impact engine performance. These mechanical systems operate at very high speeds. Different design concepts can virtually be assembled and simulated according to the requirements and based on the simulation results, a final configuration can be determined that meets the design criteria. In the current work an existing 3 cylinder SOHC type valve train was modeled using CAD software and the simulation was carried out by using the commercially available MSC.ADAMS software. The performance characteristics such as valve lift were obtained for different engine speeds. The obtained results are verified with the available literature and validated. The detailed results are presented in the form of graphs for different engine speeds. The simulated results include the valve timing, valve lift and the camshaft-rocker arm contact forces. It is observed that there is a revolution limit for the engine and a method was suggested and implemented by simulation which enhances the performance of the engine at higher speeds.
