Faster exhaustion of fossil fuel, day to day increase of automotive vehicles and stringent emission norms force the researchers to find out an alternative fuel that can be used in diesel engines with less modification or without any modification. The present experiment investigates the effect of using refrigerated methanol-diesel blend as a fuel in DI diesel engine. In this investigation, two blends of methanol and diesel were selected. One was 10% methanol and 90% diesel and another one was 20% methanol and 80% diesel. The data of pure petroleum diesel fuel operation was taken as a base line configuration to examine the effectiveness of the two blends.The results show that the use of refrigerated methanol-diesel blend, keep the combustion temperature low and increases the ignition delay. It also showed better reduction in NOx and visible smoke. It may be concluded that refrigerated methanol blend can be readily used in diesel engine without significant modification of engine and fuel system. © 2015, Sphinx Knowledge House.
