Random extraction and consumption of fossil fuels have leads to a reduction in petroleum reserves. As for as developing countries like India is connected the need to search for alternative fuels is most urgent as India is heavily dependent upon the import of petroleum to meet its demands for automotive and power sectors. This has inspired curiously in alternative sources for petroleum based fuels. An alternative fuel must be economically competitive and environmentally acceptable. India has great potential for production of biofuels like Biodiesel from vegetable seeds. In the quest to find an alternative to the existing diesel and petrol fuels various Biodiesel and alcohol has been tried and tested in the Internal Compression engine. In this direction, an attempt has been made to investigate the performance and emission characteristic of Biodiesels and compare it with diesel. The Biodiesels considered are Tamanu, Mahua and Pongamia were tested with four stroke diesel engine. A drastic improvement in reduction of Hydrocarbon (HC) and Carbon monoxide (CO) were found for Biodiesels at high engine loads. Smoke and Nitrogen oxides (NOx) were slightly higher for Biodiesels. Biodiesels exposed similar combustion stages to diesel fuel. Therefore use of transesterified vegetable oils can be partially substituted for the diesel fuel at most operating conditions in term of the performance parameters and emissions without any engine modification.

Alternative fuel sources are needed to be developed to meet the escalating demand for fossil fuels. Also from an environmental point of view, these most modern resources of fuels must be environment-friendly. The rapidly increasing consumption of fossil fuel and petroleum products has been a matter of concern for many countries which imports more crude oil. So, there is necessary for the development of new energy sources. The biomass, edible oil, inedible oils from plants and fish fat oil are imperatives and seen to be a potential substitute for diesel fuel. Acid and Base catalyzed transesterification is the most acceptable process for biodiesel production. In this project, an attempt towards finding the effect of alternate fuels as a substitute over diesel and reduce its consumption to lessen the environmental effects. Biodiesel has been extensively used in diesel engines as a partial substitute in the past few decades. The present investigation is carried out with blending up fish oil biodiesel with diesel in varying proportions to test out the emission and performance characteristics of direct injection single cylinder, four strokes, and air-cooled diesel engine. The fish oil biodiesel was produced by the transesterification process and obtained fish oil biodiesel blended with diesel fuel with various propagations of B20, B50, B75 & B100. These blended fuels were further investigated in a diesel engine with variable speeds such as 1000rpm, 1250rpm, 1500rpm, 1720rpm, 2000rpm 2250rpm & 2500rpm. In this comparative study, the effects of fish oil biodiesel fuel blends are compared and evaluated with pure diesel.

The world needs an alternative fuels that could maintain the world running on its wheels due to the increasing energy demand and uncertainty in availability of the fossil fuels. The present investigation analyzes the scope of utilizing the Deccan hemp oil based biodiesel derived from jute seed as an alternative to the diesel. Experimental investigation was carried out at diesel engine with different loads from 0% to 100% and 10% overload condition under a constant speed of 1500 rpm. It was found that the reduction in brake thermal efficiency and higher brake specific fuel consumption was observed with biodiesel in comparison with diesel. The carbon monoxide (CO), carbon-dioxide (CO2), unburnt hydrocarbon (HC) and nitric oxide (NO) emissions for Deccan hemp oil based biodiesel were reduced by 0.2% vol, 1.6% vol, 62.5%, 36.84% whereas slightly higher smoke emission was observed when compared to diesel fuel. These studies revealed that Deccan hemp oil based biodiesel can be used as a fuel in compression ignition engine without any engine modifications.

The depletion of fossil fuels as well as the rises of greenhouse gases had caused most government worldwide to follow the international energy policies for the use of biodiesel. One of the economical sources for biodiesel production is waste cooking oil. The use of waste cooking oil is more sustainable if they can perform similarly to conventional diesel fuel. This paper deals with the experimental study carried out to evaluate the engine performance and exhaust emission of diesel engine operated by biodiesel from waste cooking oil at various engine speed. The biodiesel used are known as B5, which contains of 5% of waste cooking oil and 95% of diesel fuel. The other one is B20, which contains of 20% of waste cooking oil plus 80% of diesel. Diesel was used as a comparison purposes. The results show that power and torque for B5 give the closest trend to diesel. In terms of heat release, diesel still dominates the highest value compared to B5 and B20. For exhaust emission, B5 and B20 showed improvement in the reduction of NOx and PM.

Biodiesel is a renewable energy resource consisting of the alkyl monoesters of fatty acids obtained from vegetable oils, waste cooking oils, or animal fats. Biodiesel has been noticed recently as an alternative to fossil fuels. Previous studies have shown that biodiesel produces less pollutants compared to diesel fuel. Biodiesel fuel increases the emission of NOx exceptionally. Recently, it has been found that antioxidant addition to biodiesel is a solution to solve the problem. The purpose of this research is to study the effect of antioxidants addition on the emissions of CO, HC, and NOx from biodiesel fuel. Exhaust emissions of an agriculture diesel engine were studied using biodiesel blend with a 500 ppm propyl gallate (PrG) (propyl-3,4,5-trihydroxybenzoate) and butylated hydroxy anisole (BhA) (2-tert-butyl-4-methoxyphenol) as two major antioxidants. Biodiesel used in this research was prepared through NaOH catalyzed transesterification of a waste cooking oil that originally was taken from sunflower oil, with the assistance of ultrasonic homogenizer. After biodiesel production, five blends including neat diesel, B10, B20, B20 + 500 ppm PrG, and B20+ 500 ppm BhA were used as fuel and the emitted gases were analyzed. The results of this work demonstrated that the addition of antioxidants has no significant effect on lowering CO emission, as well as lowering HC; but the addition of antioxidants results in more efficient reduction of NOx emission from diesel exhaust. In general, BhA showed better results compared to PrG.

Di Diesel Engine

Development of environmental friendly fuels is the ever constant endeavor in the field of engine technology. Owing to the merits of Diesel fuel, number of vehicles operated with Diesel are increased to meet the needs of multiplied population. However, depletion of fossil fuels and environmental pollution are the main concerns with the diesel engines. Usage of bio-fuel is found to be the prominent technology in compensating fossil fuels depletion, whereas emission control is a major setback. Suspension of nano particles in the conventional fuels termed as Nanofuel is the prominent technology in emission control. Hence, the present work is aimed to investigate the influence of TiO2 nano particulate in Diesel on the performance and emission characteristic of single cylinder Diesel engine. From the experimental results it is observed that the performance of the engine is marginally increased with the suspension of TiO2 nano particles whereas the reduction emissions are considerable.
