Studies on the performance of diesel Engine with green synthesized NanoMaterial doped diesel fuels

Abstract

All over the world, the research on the emerging applications of doping of engine fuel with nano particles to modify the ignition mechanism is being carried out. Diesel engines are widely used in transportation (automobiles), power generation and heavy machineries like mining equipments. Due to the cost of fuel and the concern about pollution, lot of studies are carried out to develop clean and efficient diesel engines by doping the diesel fuel with nano additives. Therefore, there is an extensive study going on across the world to improve the performance of diesel engine by doping the diesel fuel with nano materials to enhance the efficiency of the engine and also to reduce the emission.Green synthesis of nano metal oxide is an emerging field where the plant extract is used as an alternative method to produce metallic nano materials in a clean and nontoxic manner in which the environment is not affected. Research on the green synthesis of nano materials with the use of plant derived agents for metal salts is (Green Synthesis Research) also going on across the world. Properties like electrical conductivity, colour, strength and catalytic property are remarkable properties due to the influence of small dimensions of nano particles.In this research work, an experimental set up has been developed using a stationary, single cylinder, four stroke, direct injection, constant speed, variable compression ratio diesel engine. An eddy current dynamometer is used for varying the load conditions. The crank angle at which the fuel injected is 23° before TDC. The operating speed of the engine is 1500 rpm and the maximum power generated by the engine is 3.7 kW. A piezo-electric pressure transducer is used to measure the cylinder pressur newline
