Abstract: Automobile Industry is the largest industry in the world. Automotive engines need to be reconditioned after certain running. The frictional torque of a half engine (which consists of cylinder block, pistons with rings and gudgeon pins, connecting rods, crankshaft and bearings) is about 75% to 80 % of the total frictional torque of that engine. The components of new engines are manufactured with high degree of automation and accuracy but the same is not available during their reconditioning. Obviously, due to difference in accuracy of CNC machines and GPMs, a newly manufactured half engine has comparatively less frictional torque than a reconditioned one. This results in somewhat poor performance of a reconditioned engine as compared with the new one. The objective of this research work is to design & develop a test rig which could measure the frictional torque of a reconditioned half engine accurately and to bring quality consciousness in engine reconditioning business.
