The diesel engines are frequently used in transportation, power generation and many other applications including industrial and agriculture sector. The major pollutants from diesel engine are smoke, particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOX) and un-burnt hydrocarbon (UHC). Due to this major pollution we use biodiesel-diesel blend fuel. This mixture (Bio-Diesel and Diesel) used in Diesel engine without engine modification. The main advantages using mixtures of biofuels in diesel are: the fact that biodiesel is not harmful to the environment and the price of biodiesel is smaller than diesel. It is more energy efficient. We use mixture of biofuel in diesel fuel. This mixture used in Diesel engine without engine modification. IC Engine use in wide area for example domestic purpose, industry, various private sectors etc. Power and fuel consumption plays important role in Diesel Engine. Analysis of this parameter will not be clear from experiment data. Minimize of this problem we use computational fluid dynamics simulation (CFD). The experimental work presented in this Paper is mainly divided into three main parts. In First part, the performance and emission characteristics is evaluated by using pure Diesel, separately, in Single cylinder, four stroke, compression ignition diesel engine at constant speed of 1500 rpm with varying load (0.2,6.1 and 12.1 bar) and compression ratio (16 and 18). The performance parameters selected are brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), and emission parameters as NOx, O2, CO, CO2 and HC. In second part, The performance and emission variables evaluated by using bio- diesel and diesel blend. In third part, The Computational fluid dynamics simulation of four Stroke diesel engine.
