In this work, a new mechanical cam phaser (MCP) system is developed. This MCP system is simple, reliable, and cost-effective, and also offers good control. Phasing of either intake, exhaust or both intake and exhaust cam can be achieved with this system. A prototype of the mechanical cam phaser has been tested on a motored rig to validate its dynamic characteristics. The system was tested onto a small two wheeler engine and this paper describes the newly developed MCP mechanism and its effects on the performance of a small two wheeler engine.
