The strict emission laws, deteriorating environmental conditions, the depletion of oil reserves and the increasing price of petroleum fuels have forced the world to find alternatives fuels. Biodiesel, the promising alternative fuel can be used in diesel engines with little or no modifications. The properties of biodiesel are similar to those of diesel fuels. It can use as a fuel in diesel engine by blending with diesel The use of non-edible oil is more beneficial as compared with edible oil. Various non-edible oil seeds like Jatropha, Karanja, Neem etc. are widely available in India. Among them, Karanja has a potential to be used for the production of biodiesel. Karanja, are multipurpose non-edible plants can be cultivated on any type of soil such as degraded forests, boundaries of roads and irrigation canals. Its seeds contain 27–39% of the oil.

The drawbacks associated with bio-fuels can be minimized by making modifications to combustion chamber. Modification of combustion chamber is achieved by providing an air gap in between the crown and the body of the piston with the top crown made of low thermal conductivity material. Experimentation is carried on a diesel engine with brass as piston crown material and karanja as test fuel, which is found to be a better alternative fuel based on the tests carried out prior to modification. Investigations are carried out on the performance of the engine with modified combustion chamber consisting of air gap insulated piston with 2 mm air gap with brass crown when fuelled with karanja oil. Comparative studies are made between the two configurations of engine with and without modification at an injection timing of 29obTDC. Performance, heat balance and emission plots are made with respect to brake power. Fuel consumption increased with modification. The mechanical and volumetric efficiencies are similar in both the cases. Indicated and brake thermal efficiencies got reduced with modification. But, it is good to see that HC and CO emissions are showing positive trend. Thus, the present investigation hints the possibility of improvements while making piston modification and providing air gap insulation.

In this experimental study, a four stroke diesel engine was conducted to investigate the effect of adding water-based ferrofluid to diesel fuel on engine performance. To our knowledge, Magnetic nanoparticles had not been used before. To this end, emulsified diesel fuels of 0, 0.4, and 0.8 water-based ferrofluid/Diesel ratios by volume were used as fuel. The ferrofluid used in this study was a handmade water-based ferrofluid prepared by the authors. The results show that adding water-based ferrofluid to diesel fuel has a perceptible effect on engine performance, increasing the brake thermal efficiency relatively up to 12%, and decreasing the brake specific fuel consumption relatively up to 11% as compared to diesel fuel. In addition, the results indicate that increasing ferrofluid concentration will magnify the results. Furthermore, it was found that magnetic nanoparticles can be collected at the engine exhaust using magnetic bar.

Sulfur free synthetic diesel fuels can be produced using gas to liquids (GTL) technology, and may prove useful as a substitute for conventional diesel fuels when oil reserves are depleted. With non-detectable amounts of sulfur and aromatics, these fuels should generate lower emissions and enable catalytic clean up. This paper presents the results of a durability test conducted on a Detroit Diesel Series 50 diesel engine-generator operating on two synthetic GTL diesel fuels. Besides providing a comparison of diesel emissions, the paper also provides a comparison of generator fuel efficiency and brake specific fuel consumption between the synthetic fuels and conventional diesel. Documented emissions include total hydrocarbons (THC), carbon monoxide (CO) and oxides of nitrogen (NOx). All tests on the diesel engine reported were conducted at the factory set injection timing. As the best performance of an engine on a particular fuel may be affected by injection timing, further tests of the synthetic fuels at different injection timings are needed and will be discussed in future work.

From last three decades scientists have explored the alternative fuel to substitute petroleum diesel for CI engine. One of the promising alternative fuel is biodiesel which has potential to substitute the conventional fossil fuels in near future. In the present study the author has considered Karanja biodiesel blended with n-octanol as an oxygenated blend to evaluate the performance, emissions and combustion features of diesel engine. The obtained results were improved relative to mineral diesel. The increment of BTE by 10.40% and decrement of BSEC by 13.20% were observed by using the blend KME80O20compared with neat JME at full load . Significant reduction in emission of HC-15.68%, CO-44.73%, smoke opacity -19.31%compared than diesel and reduction in NOx 3.04 % compare to neat KME were observed for KME80O20.This signifies improved combustion characteristics while utilizing n-octanol up to 20% as blend with KME in CI engine.

Biodiesels which have been derived from non-edible vegetable oils are bagging the interest of researchers. These have been recognized as the potential alternatives of regular petroleum fuels. In this work, oil extracted from Juliflora seeds is converted as biodiesel by the transesterification process and used as alternative fuel in diesel engines. The tests are conducted by using diesel, B10, B20, B30 and B40. The experimental results of this study have disclosed that the Juliflora biodiesel blends have shown similar characteristics as diesel fuel. The BTE, CO, HC and smoke emissions are low for biodiesel blends while BSFC and NOx emissions are slightly higher. Taking all results into account it can be clinched that B10 blend of Juliflora biodiesel has viable option for diesel engine applications.

Water-in-diesel emulsion (WiDE) fuel is a promising alternative fuel capable of reducing nitrogen oxides (NOX) and particulate matter (PM) in diesel engine exhaust while simultaneously preserving combustion efficiency of the engine. However, the instability of WiDE fuel—and the high costs of production and transportation—hinder its commercialization and widespread use. An on-board ultrasonic WiDE fuel supply system is proposed as a solution to this challenge. This system allows diesel fuel and water to be continuously emulsified on-board a diesel vehicle. Diesel fuel and water, stored in individual reservoirs, are conveyed in specific ratios to an in-line mixing chamber and are rapidly homogenized by ultrasonic cavitation before entering the fuel injectors. The produced emulsion fuel is then supplied to the engine. A proof-of-concept study was conducted to compare exhaust emissions between emulsion fuels and conventional fuels. Open-flame combustion experiments were conducted using a lab-scale burner to test the system with both diesel and biodiesel fuels. Unique optical diagnostics and image-processing techniques were used to estimate PM emission levels. Results showed a reduction of PM with the use of the on-board WiDE system compared to traditional diesel fuels. PM emissions from biodiesel fuel were reduced by 58% when water-in-biodiesel emulsion was combusted with 2% water. Additionally, a PM emission reduction of 35% was achieved through emulsification of diesel fuel with 2% water. This prototype demonstrates the potential for the on-board WiDE fuel supply concept to both overcome the traditional barriers hindering the commercialization of WiDE fuel and preserve its low-emission and superior combustion efficiency characteristics.

The increasing energy demand and pollution due to fossil fuels influence the necessity of finding a appropriate alternative fuel for a cleaner environment and to sustain the usage of diesel engines in the automobile sector. This research focuses on such exploration of new alternative fuel (biodiesel) and to study its effect on emission and the performance parameters at a 1500 rpm constant speed on a 4-stroke, single-cylinder, variable compression ratio (VCR) diesel engine. The biodiesel from the sesbania aculeate seed oil is produced through the transesterification process.  The blends of sesbania aculeate oil methyl ester (SAOME) with diesel mixture SAOME10, SAOME20, SAOME30, and SAOME40 are used as fuels at various engine loads (20% to 100%) and different compression ratios (CR) (16.5, 17.5 and 18.5). The emission and performance indicators of the proposed biodiesel are analyzed and an evaluation is made with diesel. The experimental outcomes demonstrate that for SAOME20, brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) are respectively 12.3% lesser and 8.21% higher than diesel under peak load at CR 18.5. Also the experimental investigation confirms a significant emission decrease in NOX, HC, and CO when there is an increase in CR and load.
