In an adiabatic engine (or insulated engine), the energy loss through cooling system is avoided by applying a layer of insulating material over the walls of the combustion chamber the commonly used insulating materials are ceramic coatings such as silicon nitride, silicon carbide, zirconia (zirconium oxide) etc. Diesel engines are widely used in many areas like automobiles, locomotive marine engines power generations etc, due to its high power output and thermal efficiency even though the diesel engines give more benefits, the human discomforts caused by the pollutant emission of these engines have to be considered. Hafnium oxide (hfo 2) and zirconium oxide (zro 2) are two high-k materials having the potential to replace silicon oxide (sio 2) as the gate dielectricatmospheric molecular contamination can affect the quality of the new gate dielectric film in a manner similar to sio 2characterization of contaminant adsorption behavior of these high-k films should assist in deciding their potential for.
