Department, RYMEC/VTU, INDIA) Abstract: Combustion reaction in the internal combustion engine depends on many different variables, one of the most important factors in an efficient combustion reaction is the ability of the reactants, the fuel molecules and the oxidant molecules, to interact with each other, Most fuels used in internal combustion engines are in liquid state, like gasoline, diesel, biofuels, and since combustion occurs in the gas phase, achieving a substantially even dispersion of fuel molecules among oxidant molecules can prove difficult due to the vapor pressure of the liquid, Therefore, an efficient combustion reaction would involve providing for the fuel molecules to be substantially and evenly dispersed throughout the oxidant molecules, thereby allowing sufficient interactions between the reactants and promoting the combustion reaction. Conventional systems and methods attempt to remedy this problem by increasing the quantity of gas phase fuel molecules by increasing the temperature of the liquid fuel to increase the vapor pressure. The present invention has been developed in response to the present state and in particular, in response to the problems and needs that have not yet been fully solved by currently available conventional system. Hence we have designed a new fuel supply system where the petrol/biodiesels (having low viscosity ) is atomized using the ultrasonic sounds and allowing it to pass through the convective pre-heater where the atomized fuel is converted in to the vapor form (gaseous form) using the exhaust gases from the outlet valve of the engine ,which are at the sufficient temperatures to vaporize the bio-diesels and study of these system behavior by using bio-diesel as alternative fuel in the vapor form in the present petrol engine and to check the emission like CO, HC from the exhaust gasses of petrol engine with a 4-s petrol engine. The project’s goal is to develop specific knowledge as to whether these methods will increase the efficiency and oil is an acceptable supplemental fuel.

Introduction It is quite common nowadays to learn that every country is in the race to find suitable and affordable alternative fuel options for diesel engine as the present-day diesel fuel reserve is depleting fast. Even though the petrol vehicles are more in population, The research of alternative fuel for petrol (SI) Engines are very less In addition, the price of conventional petrol fuel is sky rocketing due to great demand, exponential increase of vehicles number on road and political turmoil. Therefore, it is an urgent need for India as well to search for an option to run Petrol engine using a fuel other than conventional and petroleum fuels. Research work on biodiesel reveals that large number of experimental studies of biodiesel, derived from various feed stocks, as fuel for engines used for transportation and or other applications have been carried out all over the world. Application of biodiesel, as a fuel in transportation vehicles, has nowadays become common in almost all oil importing nations, But when we compare population of the domestic vehicles (petrol vehicles) with transportation vehicles (Diesel vehicles), the Population of the domestic vehicles is more hence we have to concentrate and find alternative fuel for petrol vehicles also. We know that the combustion reaction in the internal combustion engine depends on many different variables, one of the most important factors in an efficient combustion reaction is the ability of the reactants, the fuel molecules and the oxidant molecules, to interact with each other, Most fuels used in internal combustion engines are in liquid state, like gasoline, diesel, bio-fuels, and since combustion occurs in the gas phase, achieving a substantially even dispersion of Bio-fuel molecules among oxidant molecules can prove difficult due to the vapor pressure of the liquid, Therefore, an efficient combustion reaction would involve providing for the Bio-fuel molecules to be substantially and evenly dispersed throughout the oxidant molecules, thereby allowing sufficient interactions between the reactants and promoting the combustion reaction. Conventional systems and methods attempt to remedy this problem by increasing the quantity of gas phase fuel molecules by increasing the temperature of the liquid fuel to increase the vapor pressure. The present invention has been developed in response to the present state and in particular, in response to the problems and needs that have not yet been fully solved by currently available conventional systems. Hence we have developed a special system where the use of biofuel in gasified form using convective heat exchanger which works as the heat recovering system. This system pre-atomize the Bio-fuel molecules and they are heated to 200-300°c from engine exhaust gases and they are vaporized and these gases are sent to inlet of the engine. Here we are using Bio-fuels as 100% Turmeric Leaf oil and blends of Methanol, Turmeric leaf oil with petrol in specially designed
