“…When the IOP was increased to 240 bar from the standard IOP (210 bar), carbon dioxide emission rose by 9.52%, 5.62%, 4.9%, 1%, and 9.1% for NiO (25 ppm), ethanol 5%, methanol 5%, and DEE5% fuel additives in the base blend. Similar results were observed when NiO (50 ppm) was used in Neem biodiesel and the resultant increase in CO 2 was around 12% 29 …”

The usage of biodiesel blends is restricted due to its low fuel consumption and high thermal NOx. The current study exhibits the usage of four different fuel additives methanol, ethanol, diethyl ether, and NiO nanoparticles in Neem biodiesel blend (NB25) to shore up the usage of neem oil methyl ester. Performance and emission experimentation of a compression‐ignition engine fueled with NB25 having fuel additives were conducted at varying injection opening pressures (180, 210, and 240 bar) and static injection timings (19°, 23°, and 27° bTDC). The results indicate that when NiO fuel additives were doped in the NB25 blend, high peaks of NOx were found with betterment in performance features with a lower CO and HC emission.

“…Biodiesel, when fuelled in diesel engines, improve their performance and reduces certain emissions but promotes higher thermal NO x . In order to resolve these issues, many investigators have resorted on studying effects by varying the engine parameters such as injection opening pressure, 9,10 compression ratio 11,12 and static injection timing 13,14 . Of all engine parameters, compression ratio (CR) marks a noteworthy parameter as biodiesel is much denser and lesser volatile fuel than that of conventional diesel.…”

The utilization of biodiesel‐diesel blends in compression ignition (CI) engines are a viable option for the current energy crises. But due to better combustion features of biodiesel‐diesel blends leading to high NOx release from engine exhaust hinders the use of such blends. Usually all of the harmful exhaust emissions like HC and CO reduces marginally, except nitrogen oxides at higher compression ratios with biodiesel blended fuel. The present paper focuses on the study of variation of compression ratio and use of NiO nanoparticles in neem biodiesel‐diesel mixture (NB25) at different braking loads. A total of four test fuels of NB25 blend were prepared having nickel oxides at different concentration levels of 25, 50, 75, and 100 ppm. The current findings reveal that the use of 75 ppm of NiO in NB25 blend reduces the amount of thermal NOx by 6.2% compared to the absence of nanoparticles. Also, the performance parameters such as brake thermal efficiency improved by 2.9% and brake specific fuel consumption reduced by 1.8%. The presence of 75 ppm of NiO in NB25 not only shows best performance and also lower harmful emission.

“…This work also aims to show a comparison between the total emissions (CO 2 , NO x , SO x , PM 2.5 ) and CO 2 emission caused by the E‐bus TS (supercapacitor E‐bus) with other available options of E‐bus and with the existing transit system (diesel, biodiesel, and CNG). There are various studies on biodiesel and its scope in reducing vehicular emissions 53‐56 . The study of the performance of biodiesel shows that the diesel engine fueled with neem biodiesel blend (compared to other fuel blends) have more impact on emission reduction.…”

Catering to the growing demand for urban mobility and emphasis on reducing air pollution in towns and cities are mutually conflicting objectives. One solution is a paradigm shift of the transportation policies from personal vehicles to public transportation system using electric buses. Using electric bus fleets for public transportation is not straightforward in Indian cities for two reasons, viz., weak electricity grid and predominantly coal‐based power generation. In this work, a novel transportation system, that uses solar PV generation and large capacity batteries, is analyzed for its impact on air pollution and environmental sustainability. A detailed well to wheel analysis of the system, for various power generation scenarios, is presented and also compared with the existing ones. The analysis done in this work answers the question: “Can the electric bus‐based public transportation contribute towards emission reduction in transportation?” The results also elaborate that to reach the target under the Paris Protocol, India has to take drastic majors like phasing out of coal by 2030. To phase out Coal, India has to reduce its contribution by 5% each year from now and use renewable energy sources extensively.
