“…The deviation of hydrocarbon (HC) for fuels is shown in Figure 4. HC emission from palm oil methyl ester and diesel blends is lower than diesel (Devarajan et al, 2017a;Saikrishnan et al, 2017). HC emission reduces with the addition of CeO 2 nanoparticles at various proportions.…”

This work examines the consequence of employing cerium oxide (CeO 2) nanoparticles at a different proportion (30 ppm, 60 ppm and 90 ppm) to palm oil methyl ester and diesel blends (B20) in water-cooled single cylinder four stroke diesel engine. Adding nanoparticles is a strategy to improve the performance and reduce emissions of the biodiesel. Prepared samples are fuelled to diesel engine by admitting exhaust gas recirculation (EGR) of 10% and 20% by volume. The main intention of this study is to lessen the nitrogen oxide (NO X) emissions for diesel and biodiesel blends. Experimental results found a significant reduction NO X , carbon monoxide (CO), smoke and hydrocarbon (HC) emissions at 10% EGR rate. However, brake specific fuel consumption is increased with significant lower brake thermal efficiency by admitting EGR of 20% by volume. Thus, it can be inferred that EGR of 10% by volume is an optimal way on reducing harmful emissions without compromising much on performance aspects of biodiesel fuelled diesel engine.

“…However, with ethanol mixing, the NOx contaminants were increased. With incorporating ethanol, the added advantage of the hybrid fuel-ethanol and the rise in octane numbers is accomplished with 20% ethanol added to pure petrol [ 14 , 15 ]. There has been dramatic rise in torque, gasoline consumption, CO 2 emissions, decreased carbon emissions, and hydrocarbon emissions.…”

This work focusses on a novel technique of producing bioethanol from fermented pomegranate fruits waste by using Saccharomyces cerevisiae , commonly known as baker's yeast. Four different blends of bioethanol, namely PE10, PE15, PE20, and PE25 were experimented at various operating speeds. It was inferred that the addition of ethanol enhanced the consumption of fuel as well as braking capacity. However, thermal performance was observed to be declined. PE15 blend exhibited optimum brake thermal efficiency at full load condition when compared with unleaded fuel. Brake specific fuel consumption of PE15 was noticed to be lower at different operating speeds among all the blends. Oxides of nitrogen as well as carbon dioxide emissions were increased as the proportion of ethanol in pure fuel was increased. Hydrocarbon and carbon monoxide emissions were reduced, while increasing the ratio of ethanol relative to pure gasoline, except PE10 blend. The combustion characteristics were also studied. Lower value of coefficient of variation revealed stable combustion. This study conclude that PE15 can be used as an alternative fuel.

“…Another study presented by Saikrishnan et al [4] supports these findings and the hypothesis of a reduction in emissions due to better combustion, and it also notes that there is an increase in fuel consumption due to the fact that ethanol has less calorific power. The study was done on a three-cylinder four-stroke SI engine with four gasoline-ethanol fuel blends (E0, E5, E10, E15), and the results showed that the E10 blend outperformed the other blends tested.…”

We present a comparative study of fuel consumption, emissions factors, and vehicle-specific power of a light vehicle operating with two gasoline–ethanol blends as fuel: commercial gasohol (E7.8) and an alternative mix with 10% v/v of ethanol (E10). For this purpose, a vehicle in the city’s fleet was equipped with a central system of data acquisition, whose main function was to capture second-by-second data of the air intake of the engine, the emissions concentration levels in the exhaust, the distance traveled, vehicle speed, and environmental conditions during testing. The measuring campaign was carried out in the city of Lima Metropolitana. Fuel consumption was calculated indirectly, using air intake measurements. The vehicle’s engine emissions were analysed using the mass flow rates of CO2, CO, HC, and NOx, as well as the vehicle-specific power. The results show that, in traffic conditions, the change in fuels does not affect the consumption. On the other hand, a correlation was found between the vehicle-specific power and the emissions mass flow. During the comparison between fuels, the results showed an increase in the mass flow standard deviation when using E10.
