The increasing world population and the level of prosperity have led to an increase in the need for transportation. In the historical process, the increase of the speed of transportation vehicles has been possible with the invention of internal combustion engines. Internal combustion engines are heat engines and use different fuels as an energy source. While combustion of fuel chemical energy transforms to the useful work and is obtained engine power and torque. To increase engine power and torque some innovations have been made for internal combustion engines such as electronic ignition system, fuel injection system, valve timing system and increasing compression ratio etc. On the one hand, these developments lead to increasing engine power and torque, emission regulations obstruct these outputs. Fuel additives are chemical compounds that can help to optimize between emissions and engine power and torque. Moreover, fuel additives are mixed with raw fuel, in order to get improving combustion efficiency, lower fuel consumption, decreasing engine wear, preventing failures, and better running in cold weather. Over and above the types and amounts of fuel additives may alterable depends on the fuel type, fuel producer and climatic factors.
