A test rig was developed to carry out the present investigations. Necessary instruments and equipment were setup after calibration for measurement of important engine parameters. The test engine setup consisted of Kirloskar AV1 single cylinder direct injection, water-cooled, 4-stroke diesel engine with a rated output of 3.7 kW at 1500 r/min. The test engine has been modified to measure various parameters required to determine its performance. To make the engine to work on dual fuel mode, arrangements were made to induct LPG through the intake manifold.
