“…In this study, it is found that diesel has high Bthe throughout the load compared to other blended fuels 37 . At full load D80B10RW10, D70B20RW10, and D60B30RW10 gives 1.46%, 2.86%, and 3.91% lower Bthe than diesel, this is due to low‐calorific value of biodiesel and rice wine alcohol 38 . In general, Bthe decreased as mass flow rate increased because Bthe is inversely proportional to mass flow rate and calorific value, correlating this factor, Bthe mainly depend on mass flow rate because calorific value is fixed for particular fuels, where diesel‐biodiesel‐alcohol blend mass flow rate is found high as compared to diesel 42 to produce certain brake power, as brake power is constant for all fuels at particular load 14,31 therefore, it is known that higher blends of biodiesel gives low Bthe 56,57,62 due to low‐calorific value, low volatility, and high‐latent heat compared to low blend of biodiesel and diesel.…”

“…At initial load, BSEC is found to be high due to energy loss of test fuels in the combustion that is, escape of unburnt hydro carbon molecules in the exhaust valve, which leads to high energy consumption 39 . Therefore, BSEC falls gradually as the engine load is increased 12,31,38,42,46,54 because at high load it achieved adequate temperature and pressure to perform healthier combustion where the energy loss in the combustion is minimum 40 . At maximum load D80B10RW10, D70B20RW20, and D60B30RW10 gives 6.1%, 16.2%, and 26.3% higher BSEC than diesel this is due to heating value of blended fuels, that is, heating value decreased as the biodiesel blend increased, 41 so high blend of biodiesel results high BSEC 58…”

Synthesis of biodiesel from raw based waste materials is much more influential for economic support of the nation, as many researchers have concluded that the use of fossil fuels is no longer sufficient in the coming decade, so one should look into the alternate source of energy in order to sustain the energy for our daily needs. Neem methyl ester produced from waste neem seed, which is cheap, and available in the surroundings has an opportunity for nonconventional sustainable energy and whereas, rice wine alcohol obtained from waste cooked rice by fermentation process can be checked for diesel engine operation, here study investigates the influence of these synthetic fuel diesel‐biodiesel‐alcohol blend in combustion, performance and emission characteristics. Biodiesel and alcohol are introduced to enhance oxygenation properties of the test fuels, and also adding 10% rice wine alcohol in the blends changed the physiochemical properties of the test fuels like lowered the flash point, fire point, viscosity and calorific value, where D80B10RW10 increased the cylinder pressure by 1.23% and lowered the emission like smoke opacity and unburnt hydrocarbons by 23.95%, 21.62% as compared to diesel. The overall test results conclude that a low blend of biodiesel with 10% rice wine alcohol has an opportunity to be implemented in the existing engine for the coming decade.

“…Basavaraj M. Shrigiri et al investigated the cotton seed methyl esters and neem kernel methyl esters as option biodiesels utilized in low warmth dismissal motors (LHR) to build the warmth in the burning chamber by the warm obstruction coatings. By the trial examinations creator see that at greatest burden the brake warm proficiency is lower by 5.9 % and 7.1 % and BSFC is expanded by 28.6 % and 10.7 % for CSOME and NKOME in LHR motor, separately when separate with standard diesel fuel utilized in ordinary motor [3].…”

A significant portion of the automobile and industrial sector is mostly dependent on the running of diesel engines as it is efficient and shifts a large of the goods around the globe and power various equipment. Also, as the use of energy as diesel fuel is increasing enormously with the expansion of industrial growth, diversification, this led to the accelerating global emissions, global climatic change, health issues, and exhaustion of fuels. To succumb this, alternative fuel is needed to fight against the ill effects and as a replacement to diesel fuel. Thus, vegetable oils as alternative fuels are drawing more attention as they are renewable and do not address the problem of greenhouse gas. In the present work, the cottonseed oil was chosen as the favorite among the vegetable oils due to its advantages like less pollutant level, excessive availability, etc. The transesterification process was used to produce the cottonseed oil biodiesel. This research aims to investigate efficiency, emission characteristics by using smooth diesel, cottonseed oil, and mixtures with varying composition from 20 % to 80 % in 20 % steps to identify sustainable fuel as a substitute for existing fuel and to overcome fuel demand and enviro effects. This test was conducted on single-cylinder four-stroke water-cooled diesel engines. From the results, it was revealed that cottonseed oil and its blends have a significant influence on performance and emission characters. Keywords: water-cooled diesel engine, emission character, cottonseed oil, sustainable fuel.

“…As a result, non-edible vegetable oils, regarded as second-generation biodiesel feedstock, garnered international interest and will always be evaluated as possible biodiesel substitutes for conventional edible food crops. Rubber seed Jatropha (Gonzáles, 2016;Bokhari et al, 2016), karanja or pongamia, neem (Gurunatham and Ravi,2015), jojoba (Sánchez et al, 2015), cottonseed (Shrigiri et al, 2016) are among the famous non-edible biodiesel feedstock recently. The existence of the world second-generation biodiesel feedstocks is believed to eliminate competition for food, be more efficient, be more environmentally friendly, produce valuable by-products and be more economical compared to edible oils.…”

Biodiesel, an environmentally friendly biomass-based fuel, is gaining popularity globally as a cost-effective way to meet rising fuel demand. However, the high cost of raw materials and catalysts continues to drive up biodiesel production. An alternative feedstock with a heterogeneously catalyzed reaction could be the most cost-effective way to stabilize industrial biodiesel growth. Understanding these issues led to the idea of using waste palm oil as a feedstock for biodiesel production. While using waste materials as feedstock for biodiesel is an elegant solution, converting high free fatty acids (FFA) directly into methyl esters has some drawbacks. High FFA processes (acid esterification, then base transesterification) are costly. The commercial processes currently use a homogeneous system with sulfuric acid to catalyze both esterification and transesterification. However, heterogeneous solid acid catalysts are preferred over hazardous mineral acids for high FFA esterification because they are less corrosive, produce less waste, and are easier to separate from reactants and products by filtration, recovery, and reusability. Heterogeneous acid catalysts can also simultaneously catalyze transesterification and esterification reactions. Thus, new waste-based support for heterogeneous catalysts (solid acid catalysts) is required to convert waste oils into biodiesel.
