Cylinder Petrol Engine Test Rig

The engine is coupled with rope brake or electrical dynamometer as per requirements. For rope brake dynamometer rope wound on a pulley with spring balance is used. A water rheostat is used for loading electrical dynamometer. The test rig can determine air fuel ratio B.H.P., I.H.P. specific fuel consumption and efficiency at various loading and heat loss in exhaust gases.
