Abstract: Due to fast depletion of fuel and for the huge demand of various engine fuels in large sectors and power generation, thse biodiesel which is derived from biological wastes can be a substitute of pure diesel oil. Diesel engine has the benefits of low fuel consumption, high potency, smart economical and dynamic performance. However at the identical time, the diesel engine has high NOx and soot emissions. And these two sorts of emissions provides a trade-off relationship which can bring difficulties to satisfy the necessities of emission rules of NOx and soot. This particular paper primarily reviews regarding using of preheated bio-diesel that contains 20 percentage of pure sunflower oil (biological name-Helianthus annuus) and analyses its performance characteristics for selected blend with completely variable loads. Various experiments were carried out by employing a four stroke single cylinder, direct injection, water cooled diesel engine with suitable specifications. Helianthus oil is mixed with bio diesel for fast burning inside the engine cylinder and by doing so , the Cetane number is quite high that leads to the ignition delay shorter. Therefore the overall content is preheated somewhat in order to lift its temperature so as to boost the burning process. Incorporating to this , it reduces the various emissions such as NOx, CO and smoke capacity by 2% to 3%. Various parameters are required to outline the analysis of combustion and performance characteristics of the test fuel like brake thermal efficiency(BTE),basic specific fuel consumption(BSFC), basic specific energy consumption (BSEC),temperature of the exhaust gas and emissions like NOx, unburn hydrocarbons(HC), carbon monoxide(CO) and smoke were carried out in the specified engine.
