The shortage of conventional fossil fuels, growing emissions of combustion-generated pollutants, and their skyrocketing made biomass sources an alternative solution to this energy crisis. Current oil and gas reserves are going to last for just a few decades. To address this rising energy demand, fuels such as Biodiesel are at the forefront of alternative technologies which can act as a viable alternative for compression-ignition engines. In this present study, we have carried out a series of experiments on a four-stroke single-cylinder diesel engine using a rope brake dynamometer where we have used diesel and biodiesel as a working fuel. Thereafter we have compared the various performance parameters between them and documented the results in graphical form for easy understanding.

In the modern generation heat exchange equipment has become of great importance in many industrial processes and internal combustion engines because it increases the use of energy resources as well as conversion and reuse of energy. In recycling thermal energy, the minimization of temperature differences is more important. High-specific output engines can be developed by developing finned surfaces. Thus fins play an important role in energy. Our investigation deals with the problem of finding the optimum configuration of the fin with the maximum heat dissipation rate. This experimental study focuses on the analysis of the effectof forced convection and natural convection on the characteristics of heat transfer within the pin fin.
