Abstract The Internal Combustion Engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. Internal Combustion Engines produce mechanical power from the chemical energy contained in the fuel. Fuel characteristics play a major role in engine efficiency directly or indirectly. Diesel engines are the most efficient engines with high performance. The fuel characteristics play an important role in atmospheric pollution caused by these engines. If the efficiency of the engine is increased and developments are made in the engine, that may be helpful for the economy of today’s world. Hence additives are used for performance improvement of the engine. In this present work, experiment was conducted on Kirloskar single cylinder, four stroke, and water cooled diesel engine. Experiments are conducted with Pure Diesel, Acetone mixed with Diesel, Xylene mixed with Diesel and Toluene mixed with Diesel. Experiments are conducted at various percentages (0.5%, 0.7%, 0.83% and 1.0% etc.) of additives by volume. The effect of Acetone, Xylene and Toluene on brake thermal efficiency and specific fuel consumption (SFC) were studied and graphs are plotted. Finally, we suggest that diesel with Toulene of 1% by volume is the best fuel among the fuels used in this work. Keywords: additives, diesel engine, performance analysis

burning of the fuel and the release of high-temperature & pressure gases and work transfer between the gases and mechanical components of the engine provide the desired output.

INTRODUCTION A device that transforms one form of energy to the other is called an Engine. Most of the engines convert thermal energy into mechanical work. Such engines are called ‘heat engines’. Heat engine transforms the chemical energy of a fuel into thermal energy and uses that energy to perform some useful mechanical work. Types of Engines: Heat engines can be broadly classified into two categories: I. Internal Combustion Engines (IC Engines) II. External Combustion Engines (EC Engines) The internal combustion engine (IC Engine) is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. Internal combustion engines produce mechanical power from the chemical energy contained in the fuel. The energy is released by oxidizing the fuel, which is basically the burning of fuel inside the combustion chamber in the engine. The

The Reciprocating IC Engine has some advantages over Steam Turbines because of the absence of heat exchangers in the passage of working fluid. Hence mechanical simplicity and improved efficiency can be obtained with this type of IC Engine. In internal combustion engines, higher thermal efficiency can be obtained with moderate maximum working pressure of the fluid in the cycle. PROPERTIES OF A GOOD ADDITIVE: Additives that are to be blended with diesel have following properties. 1) It must be miscible with diesel over the range of environmental temperatures that the vehicle operates. 2) It should be such that it increases the cetane number of diesel after blending. 3) It should have minimum volatility. 4) It should not harmful to the components of the engine. 5) It should not form any gum deposits.
