In order to reduce the emission of carbon mono oxide some of the researchers have inserted the pure water inside the combustion chamber at the start of the expansion stroke. Water inserted inside the chamber get instantly vaporize, due to this the pressure during the expansion stroke get increased. With the help of this increased pressure, work done during cycle gets increased. Also with the insertion of water inside the combustion chamber reduces the value of carbon mono oxide content in the exhaust gas. Here carbon reacts with oxygen and produce CO2. During vaporization of water both sensible as well as latent heat are required, which is extract from the combustion chamber to reduce the thermal efficiency of engine. So in order to reduce the amount of heat requirement and to increase the overall efficiency of the engine, heat exchanger is used in internal combustion Rankine cycle. Here heat exchangers extract heat from the exhaust gases and transfer to pure water used inside the combustion chamber. Here in this work the effect of different flow patterns on heat exchanger has been analyzed. Also, investigated the effect of mass flow rate of water inside the tube. Furthermore, the effectiveness and overall heat transfer coefficient of heat exchanger.
