IC engines are widely used in automobile, domestic and industrial sector.  They are classified according to cycle, number of cylinders, arrangement of cylinders, fuel used, type of ignition, valve arrangement, cooling system. Test rigs are used to find out the performance of an IC engine.  It consists of an IC Engine, dynamometer, fuel measuring, air intake measuring and various other arrangements. Provision for mores test is done.
