Abstract
In this paper, a case study has been performed and analysed on a Narrow boat as practical application of Micro CHP. The Narrow boat system comprises a diesel engine and various other ancillary equipment. The engine was tested using a standard test procedure and the corresponding engine torque and power, thermal efficiency, fuel input energy and fuel consumption figures were obtained for the range of engine speeds and loads. The results showed that, the thermal efficiency at various speed and different power output not greatly affected and the engine is most efficient between 1000 and 1100 rpm.
