“…Also, a slight improvement in the properties of biodiesel‐diesel blends is also observed when these nanosized metal additives are doped in fuel. During combustion of biodiesel‐diesel with metal, oxides formally shorten the ignition delay period and increase the oxygen present in the combustion chamber, thereby reducing the soot and other deposits inside the combustion chamber 28 . The presence of metal oxide in fuel blends provides catalytic performance as they bear higher surface area to volume ratio and are more conducive to provide micro explosions required during the combustion of biodiesel 29 .…”

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.

“…The incrementation of NOx form standard SIT to 27° bTDC for NiO‐NB25, E5%‐NB25, M5%‐NB25, and DEE 5%‐NB25 was 12.9%, 6.3%, 6.1%, and 8.1%, respectively. The possession of promotion of combustion activity provided by NiO tends to provide a higher cylinder temperature, which leads to a higher NOx formation 30,40,41 . On the other hand, additives such as ethanol, methanol, and DEE do not produce such a promotion in combustion due to which the NOx was limited in their emissions.…”

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.

“…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.…”

“…The analysis here aims to check whether the electrification helps to reach the target or not. Hence, the target emission that India has set to fulfill the Paris agreement, 53 represented as a baseline in both these emissions trends (calculated using Equations ) and ()). Hence, in this work, the emission baseline is calculated by:

{TS}_{{CO}_{2 (bl) (km)}} = \frac{Annual {CO}_{2 ((), diesel in 2005)} \times ((), 1 - 0.33)}{N_{(w . d)} \times L_{avg}},

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.
