First Law of Thermodynamics states that energy can neither be created nor destroyed but can be changed from one form to another. Stored internal energy of fuels can be released chemically during combustion for doing mechanical work. In the process of converting fuel into some form of energy, the fuel first ignites and later the emissions such as the exhaust react with the ambient air. Fuels are of two types, conventional fuels and non-conventional fuels. The types of conventional fuels are fossil fuels, which include petroleum, coal, propane, natural gas, and the other types of conventional fuel such as uranium. Today, one of the world’s main concerns is the consumption rate of fuels and the impact on the environment e.g. global warming and acid rain. The automotive industry relies mostly on petroleum to run their vehicles. The availability of petroleum is limited and is becoming expensive day-by-day. Apart from the availability, there are some major concerns on the use of petroleum. Diesel is one of the petroleum products, which is used as a fuel in diesel engines. Diesel engines are widely used to power vehicles, engine-generator sets, aircraft ground support engines .......
