Multi-Cylinder Four Stroke Diesel Engine Test Rig

The Test Rig provided study of Multi-cylinder four stroke diesel engine testing. A rig comprises of a Multi-cylinder Four Stroke Diesel Engine coupled to a Rope Brake Dynamometer. With the help of various measurement the test rig can determine - BHP, IHP, mechanical and thermal efficiencies, air fuel ratio, specific fuel consumption and heat balance sheets at various loads. Special arrangements is provided by disconnecting injector for cutting off ignition of each cylinder for Morse Test.
