This is a three-day course which provides a comprehensive and up to date introduction to fuel cells for use in automotive engineering applications. It is intended for engineers and particularly engineering managers who want to jump‐start their understanding of this emerging technology and to enable them to engage in its development. Following a brief description of fuel cells and how they work, how they integrate and add value, and how hydrogen is produced, stored and distributed, the course will provide the status of the technology from fundamentals through to practical implementation.

Biodiesel was found to be a viable alternative to diesel fuel. The current research focuses on combining two biodiesels from different feedstock. This work investigates the use of ternary blends comprising diesel, Linseed oil methyl ester (LOME), and Calophyllum inophyllum methyl esters (CIME). Biodiesels were synthesized from the pristine oil using a trans-esterification process. Various proportions of biodiesel blends were prepared and labelled such as B0, B5, B10, B15, and B20. The prepared blends were tested in a diesel engine for their performance and emission parameters. Among the tested biodiesel samples, B5 displays superior performance characteristics with increased Brake Thermal Efficiency (BTE) and slightly increased Brake Specific Fuel Consumption (BSFC). The increase in Brake Thermal Efficiency and Brake Specific Fuel Consumption for the B5 blend when compared to diesel was found to be 16.11% and 4.5 % at full load conditions.

Biogas is developing as a possible replacement for fossil fuels as the globe shifts to sustainable energy sources. Organic waste, including food waste, agricultural waste, and sewage, decomposes to produce biogas. Biogas is a fuel that can be used to create electricity, heat homes, and power vehicles. The popularity of electric cars (EVs) is rising as a result of their zero emissions. EVs and biogas can work together to create a sustainable transportation option. The viability of EV charging stations powered by biogas is the main topic of this techno-economic inquiry. The study involves the evaluation of the technical and economic elements of the proposed system. The technical aspects cover power generation, the EV charging system, the biogas storage system, the biogas production process, and the biogas purification process. The capital cost, operating cost, and revenue from the charging station are all considered economic factors.

This study mainly focuses on the blending of Alumina and Titanium oxide nanoparticles (NP’s) in Spirulina biodiesel blends (SB20) to evaluate the influence of engine (performance and emission) parameters of a diesel engine. The FTIR of biodiesel was analyzed to evaluate the functional groups of biodiesel. The characterization of Al2O3 and TiO2 NP’s like SEM were reported. By using various fuel samples such as Diesel, SB20, SB20+40 ppm AO, SB20+80 ppm AO, SB20+40 ppm TO and SB20+80 ppm TO, the engine tests on the diesel engine were carried out at different load conditions. The BTE for SB20+80 ppm AO were enhanced by 12.35% and 8.4 % compared to the SB20 fuel and SB20+40 ppm AO fuel samples. The combustion parameters were improved for the NP’s as additives (Al2O3 and TiO2) fuels than the SB20 fuel sample because NP’s contain oxygen content.

The origin of many environmental and health hazardous emissions from vehicle is the consumption of more fuel. New regulations are coming up and they will all demand lower emissions from the vehicle. The Corporate Average Fuel Economy (CAFÉ 1 & 2) norms are the regulatory norms formed by the government of India for reducing the carbon footprints by reducing fuel consumption or improving the fuel efficiency of ICE vehicles. Heavy penalties are imposed to OEM who fail to meet CAFÉ regulatory norms to bring technical advancement in ICE powered vehicles to maximize their efficiency. Hence it is important to reduce the loss & improve the fuel economy. The work carried out was to reduce the gear box drag by 5- 10 %. This can significantly contribute to the overall efficiency improvement. Thus, carbon footprints of vehicle is getting reduced.

Energy demand climbs as a consequence of the inherent relationship between the rate of consumption of energy and the growth of the economy. In light of the depletion of fossil fuels and coal, it is crucial that energy efficiency techniques and policies to be implemented to support sustainable growth. This research elaborates the production and experimental investigation of briquettes made from ideal municipal solid waste (MSW), such as cardboard, food waste, and sawdust, as a feasible choice for sustainable biomass fuel as an alternate to fossil fuel. Typically, municipal solid waste encompasses nearly 42-46% of paper and cardboard based products. This research is based on various studies that have been published in the scientific literature, and it also includes details on the methodology of valorizing different wastes into energy by densification such as briquetting.

The goal of this research is to study the efficiency and emissions of diesel in combination with linseed and jatropha oil as biodiesels. These oils were trans-esterified and three ternary blends of ethanol, biodiesel, and diesel were prepared in E10-B20, E15-B20, and E20-B20 configurations. Ethanol is used as an additive to improve combustion properties. Brake power and emission tests were carried out using ternary biodiesel mixtures in a computerized single-cylinder water-cooled diesel engine. These novel ternary blends exhibit lower NO 2 and CO 2 emissions than normal diesel fuel. From the performance point of view, the blend E10-B20 has similar SFC and brake thermal efficiency to diesel. The E15-B20 blend displayed a significant reduction of around 50 % in unburnt hydrocarbons in comparison with the base diesel at heavy load conditions. In addition, the NOx value also dropped by 28% in comparison with the E15-B20 blend with base diesel at heavy load conditions.

The current study has concentrated on discovering and developing clean alternative energy sources like biodiesel and employing novel methods to reduce harmful emissions and enhance engine performance behavior. In this study, Ricinus communis biodiesel was extracted from oil using a transesterification process, and its fuel properties were assessed. The application of biodiesel in diesel engines reduces exhaust emissions; however, multiple investigators claim that the consumption of biodiesel generates greater amounts of nitrogen oxide pollutants than diesel-fueled engines, which limits the scope of biodiesel usage. In the present investigation, the combined influence of an antioxidant (tert-butyl hydroquinone (TBHQ)) additive introduced to the fuel as a fuel alteration method and SCR (selective catalytic reduction) as an after-treatment approach on NOx diminution in a Ricinus communis biodiesel -powered compression ignition engine was investigated.
