Flat plate solar collector for water pre-heating using concentrated solar power (CSP) AIP Conference Proceedings 1919, 020021 (2017) Abstract. Biodiesel is a captivating renewable resource providing the potential to reduce particulate emissions in compressionignition engines. A comparative study is conducted to evaluate the effects of using biodiesel on exhaust emissions. Exhaust smokiness, noise and exhaust regulated gas emissions such as carbon di oxides, carbon monoxide and oxygen are measured. It is observed that methanol-biodiesel blends (mustard oil, palm oil) cause reduction of emissions remarkably. Most of the harmful pollutants in the exhaust are reduced significantly with the use of methanol blended fuels. Reduction in CO emission is more with mustard oil blend compared to palm oil blend. Comparatively clean smoke is observed with biodiesel than diesel. It is also observed that, there is a decrease of noise while performing with biodiesel blends which is around 78 dB whereas noise caused by diesel is 80 dB. Biodiesel, more importantly mustard oil is a clean burning fuel that does not contribute to the net increase of carbon dioxide.

Different blends of biodiesel, bioethanol, diesel and noise pollution emitted by stationary and moving MF285 tractor

“…Therefore, in both the driver and bystander's positions, the B 25 E 4 D 71 fuel was identified as the blend with producing the least noise pollution. By increasing the percentage of biodiesel in the fuel blend, the noise pollution is reduced that concurs with the results of other studies [24,[27][28][29]33] whereas not agreeing with the results obtained by Li et al [31].…”

“…The effect of applying fuel blends on the performance of a four-cylinder engine and noise and air pollution was investigated. The results of this study revealed that although biodiesel fuel blend provided a slight change in engine performance compared to pure diesel, noise pollution decreased with increasing biodiesel percentage [27][28][29].…”

“…A thorough investigation is needed into the combination of biodiesel, bioethanol, and diesel as a fuel in the tractor, due to the changes in fuel characteristics, and its effect on combustion and engine performance [23]. The use of biodiesel fuel blends in diesel engines has had modest changes in engine performance than that of pure diesel [23][24][25][26][27][28][29]. Diesel engines working with biodiesel blends has lower air pollution (Carbon monoxide, Unburned hydrocarbons, soot, and other pollutants) compared to diesel engines with diesel fuel [36].…”

Utilization of Nanotechnology and Nanomaterials in Biodiesel Production and Property Enhancement

“…MgO, SrO, and ZnO are other nanocatalysts utilized in the transesterification procedure. Again, Fe 3 O 4 , CuFe 2 O 4 , activated carbon, and other materials can be used to enhance these catalysts' characteristics [24][25][26][27][28][29][30][31].…”

“…The ideal biodiesel production feedstock includes edible oil sources such as palm, sunflower, soybean, olive, maize, rapeseed, safflower, peanut, and coconut oil [26]. Table 1 provides an overview of the use of nanocatalysts for manufacturing biodiesel from vegetable oil, waste cooking oil (WCO) extracted from animal fat, and algal oil for different operation conditions.…”
