*Replacement of Diesel Fuel by DME in Compression Ignition Engines: Case for India DOI: http://dx.doi.org/10.5772/intechopen.104969*

still in the evolution phase and for them to match the power density, energy density, low-cost and the reliability of liquid fuels-based IC engines is expected to take at least another two to three decades. Meanwhile the IC engines technology has reached a high level of maturity, sophistication, knowledge and economy of scale. IC enginesbased power trains will continue to dominate the transportation, industrial, power generation and other sectors for next three decades. Therefore, it is imperative that solutions are found to make IC engines-based power trains clean and energy efficient. Compression Ignition (CI) engines with diesel fuel are used in many heavy-duty applications like long-distance trucks, busses, agricultural equipment, earth moving and construction equipment. Conversion of these diesel engines to use an alternative clean fuel like DME will aid in protecting the environment and conservation of energy. Primarily this will involve development of a pressurized fuel injection system and matching the fuel injection parameters to the physical and chemical properties of DME. Sufficient developments have been done in the past in development of fuel injection systems for DME fueled CI engines, therefore with the collaboration of the engine OEMs and the fuel equipment manufacturers diesel engines conversion to DME can be taken up in an economical way and in a time-bound manner. Impact of such conversions will be seen in the form of reduction of WTW energy consumption and harmful emissions.
