The present study presented an inclusive analysis of engine exhaust emission characteristics of direct injection diesel engine fuelled with diesel and biofuel. Biofuel used in this investigation was obtained by steam distillation from pine oil. A single-cylinder, four-stroke diesel engine was used for this purpose. In this work, performance characteristics like brake thermal efficiency (BTE) and brake-specific fuel consumption (BSFC) were analysed. The engine pollutants, namely nitrogen oxide (NO), carbon monoxide (CO), hydrocarbon (HC), and smoke, were examined. In addition, combustion characteristics like in-cylinder pressure and heat release rate were presented. Two engine modification techniques, namely thermal barrier coating and the addition of antioxidant to biofuel, were attempted. The advantage of thermal barrier coating is to reduce heat loss from the engine and convert the accumulated heat into useful piston work. In this work, partially stabilised zirconia was used as the coating material. The usage of antioxidant-treated biofuel in a diesel engine was said to be the prominent approach for NOx emission reduction. Three different antioxidants, namely butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), tertiary-butyl hydroquinone (TBHQ), were exclusively dissolved at a concentration of 1% by volume with PO fuel. The obtained performance and emission characteristics of the uncoated engine were compared with the thermally coated engine. From the results, it was observed that the PO biofuel may be a promising alternative in the near prospect with the thermal barrier coating technique to enhance the performance, combustion and emission characteristics of diesel engine. The PO+TBHQ blend was considered as more beneficial than PO+BHT and PO+BHA on account of its performance, combustion and emission characteristics. The effectiveness of the antioxidant was shown in the order of TBHQ>BHA>BHT.

Hydrogen is a clean alternative fuel without carbon gas emission. This paper presents a critical evaluation of the different methods available for generating hydrogen from various feedstocks. The advantages and disadvantages of each process are discussed deeply by recent literatures. Steam reforming of fossil fuels (SRF) has been proved as an attractive method and commercialized on the larger scale. However, CO2 emission that produced during the process is critical issue by this method and therefore, CO2 capture, and storage/utilization technology are required. Besides, water splitting can produce ultra-purity hydrogen and oxygen as byproduct, but this method cannot be competed with SRF because of its expensive costs. The only possible to reduce this gap is by using solar energy with low-cost as energy source for water splitting and carbon taxes are imposed by the government to support research and development. Hydrogen production derived from biomass through gasification and pyrolysis currently shown an economic visibility and expected compete with available technology in the future. Moreover, by utilizing membrane reactor and integrated with a cheaper solar energy could significantly improve biomass-to-hydrogen conversion.

This study offered a comprehensive investigation on engine performance and emission characteristics of Kirloskar make tangentially vertical (TV1) model single-cylinder direct injection diesel engine fuelled with diesel as a benchmark fuel. Steam distilled orange oil was converted into orange oil methyl ester (OME) by means of transesterification process. The physical and chemical properties of fuels were measured and conformed to ASTM biodiesel standards and compared with diesel. Likewise, the chemical compositions of the prepared biodiesel were estimated by using GC-MS analysis. OME comprises of 86.37% of (E)-3-propylidenecyclopentene (C8H12) in the maximum range. The presence of free fatty acids such as linoleic acid, palmitic acid and myristic acid in OME permits it to be the acceptable renewable resource for the production of biodiesel. Further, the work was progressed with the addition of oxygenated additives like ethanol and diethyl ether to OME to attain the improved fuel properties. Five and 10% volume of ethanol and diethyl ether were added to OME as oxygenated additives respectively. OME10DEE showed higher performance characteristics than diesel and OME blends. Further, a significant reduction in HC, NOx and smoke emission was noticed with OME10DEE. The present work recommended the application of OME10DEE as an alternative fuel on account of its better engine performance and emission characteristics than other fuel blends.
