Need of an appropriate supportable fuel for existing internal burning motors is by and large frantically felt nowadays, when oil holds are soon going to vanish from the surface of earth Biodiesel proposes one such choice The purpose of this article is to provide the physicochemical properties and characteristics of exhaust emissions from a DEE and LPG-fueled diesel engine. Fundamental properties of DEE and LPG are described and compared with the properties of the conventional diesel fuel. In addition, the applicability of DEE fuel is presented in terms of its potentials as an alternative fuel for compression ignition engines. The exhaust emission characteristics of a DEE and LPG-fueled engine are described using experimental results of different DEE and LPG with diesel blends. The most important properties of DEE and LPG are the presence of oxygen in the fuel molecule, lower ignition temperature, and high cetane number. The kinematic viscosity of DEE is significantly lower than that of diesel. However, low lower hating value (LHV), low viscosity, and low lubricity are some of the major disadvantages of DEE. LPG is considered to be one of the most promising alternative fuels not only as a substitute for petroleum but also as a means of reducing nox, soot and particulate matter. Fuels like vegetable oils, which have a high cetane number, can be directly used in neat form in a conventional diesel engine. Alcohols like ethanol also can be used in a neat form with ignition improvers like dimethyl ether (DEE) or by employing hot surfaces for ignition LPG has a high octane rating and is therefore well suited for SI engine. But when LPG is burnt in the conventional diesel engine there is a difficulty in self-ignition because of its lower cetane number. If LPG is to be used as an alternative to diesel the cetane rating needs to be improved with additives or other positive means of initiating combustion. Adding a cetane number improver to LPG is one method to improve its cetane number and its ignition quality. Emission characteristics of different DEE and LPG and diesel blends are investigated, which shows low soot, CO, NOX and other hydrocarbon emissions.
