In the internal combustion Diesel engines the most important subsystem is Intake manifold and Exhaust manifold. In the intake manifold which supplies fresh air –fuel mixture in to the cylinders where combustion takes place at high temperature and high pressure. After exhaust gases scavenged through valves from the cylinders, these gases past exhaust manifold an outlet, through which the gases flow into exhaust pipes from there to the emission control equipment of engine which consists of catalytic and thermal converters. The development of swirl can be enhanced by re-designing of inlet port of an Engine. There is further development in the swirl due to combustion process to another maximum part way in to the power stroke. Swirl can promotes the combustion process in a better way and causes efficiency increase. Better mixing of air – fuel there is a little bit changing the inlet and exhaust valve. Valve stem diameter is 9.5mm, Inlet valve diameter is 36mm, Exhaust Valve diameter is 28mm by varying the pitch 1.0mm to 2mm and thread depth of cut as 4mm and three thread per inch from this arrangement to investigate the performance by enhancing the swirl of air flow to get betterment in the performance and decrease in emissions in a (DI) direct injection diesel engine with single cylinder when compared with normal engine.

The present investigation mainly focuses on overcoming the limitations of gasoline fumigation (GF) in diesel engines by adding up nano fuel additives. Experiments are conducted to ascertain the engine working characteristics in a single-cylinder, four-stroke diesel engine using aluminum oxide (Al2O3) nano additives blended diesel as the main injection fuel along with GF as an inducted fuel. GF was achieved by controlling the electronic injector fitted at the intake manifold using open ECU software. Fuel map for GF was determined based on experiments with three divergent fumigation rates of 10%, 20%, and 30% based on energy consumption and optimized using the design of experiments. The optimization results showed 10% fumigation resulted in better performance and emission characteristics and it is selected for this present investigation. Fumigation results showed a decrease in brake thermal efficiency (BTE) at low and medium loads; increase at high loads.The two different mass fractions of 25 ppm and 50 ppm Al2O3 nano liquid are blended with diesel. Compared to GF with diesel, GF along with 25 and 50ppm Al2O3 nano additives blended diesel showed an increased BTE, maximum in-cylinder pressure, cumulative heat release rate; and reduced smoke opacity, CO, and unburned HC emissions at overall operating conditions. As the dosage level of Al2O3 increases from 25 to 50 ppm results in further enhancement of all working parameters except NOx emission. Finally, the addition of an Al2O3 nano additive is a suitable solution to overcome the limitations of GF in the CI engine.
