Development of a Test-rig for a Modern Motorcycle Engine

This paper presents experimental activities that have been performed in the Automotive Engineering Centre laboratories in Universiti Malaysia Pahang for developing a test-rig based on a modern motorcycle engine. The experimental engine test-rig was developed based on an eddy current dynamometer which was coupled to a four-stroke singlecylinder SI motorcycle engine. Moreover, the test-rig consists of all the measurement equipment, sensors and auxiliaries kits for carrying out engine testing in a sufficient way. The results of these activities have been used for validation of a one-dimensional model developed based on that single cylinder engine. Both the in-cylinder pressure trace and brake torque were used to validate the engine model. There was good agreement between the simulation and experimental results. The constructed test-rig can be utilized for further research and development programs.
