“…An E2W consumes 3-5 times less energy than a gasoline-based two-wheeler. Gasoline two-wheelers mostly use their energy (75%) in the tank-to-wheel process, whereas E2Ws mostly use energy in the production stage [13,44,45]. In a study conducted in the UK, using the tank-to-wheel process, it was found that E2Ws consume 6.1 and 2.9 times less energy than gasoline cars and motorcycles, respectively [37].…”

Electric mobility offers a low cost of travel along with energy and harmful emissions savings. Nevertheless, a comprehensive literature review is missing for the prospects of electric vehicles in developing countries. Such an overview would be instrumental for policymakers to understand the barriers and opportunities related to different types of electric vehicles (EVs). Considering the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, a systematic review was performed of the electronic databases Google Scholar and Web of Science for the years 2010-2020. The electric four-wheelers, hybrid electric vehicles and electric two-wheeler constituted the electric vehicles searched in the databases. Initially, 35 studies identified in the Web of Science that matched the criteria were studied. Later, 105 other relevant reports and articles related to barriers and opportunities were found by using Google Scholar and studied. Results reveal that electric four-wheelers are not a feasible option in developing countries due to their high purchase price. On the contrary, electric two-wheelers may be beneficial as they come with a lower purchase price.

“…The emission of CO decreases by 0.363, 0.266 and 0.356 g km -1 for light-duty vehicle when EA, MTBE and ETBE oxygenate blending ratios are increased (Lim et al, 2019). When Euro III motorcycles are equipped with catalyst and electronic fuel injection systems the CO and hydrocarbons in their emissions can be significantly reduced in comparison with Euro I and II carbureted motorcycles (de Assis Brasil Weber et al, 2019). There are certain potential hazards and unwanted side effects when using E10 fuel in a motorcycle.…”

“…In the transportation sector, 90% of greenhouse gas is being emitted by the use of gasoline and diesel fuels in the United States (U.S. EPA, 2019). The developing countries are contributing to 94% of the growth in the transportation energy sector (de Assis Brasil Weber et al, 2019). World transport energy consumption is set to reach 3906 Mtoe in 2040 (U.S. EIA, 2016a).…”

This study investigated the effects of blending ethanol with gasoline on the exhaust emissions of fuel-injected motorcycles. Regulated gasoline (RF), and 15 (E15) and 30 (E30) vol% ethanol fuel were used as test fuels. Measurements of several air pollutants (CO, HC, and NO x ) and organic air pollutant groups were conducted for two new fuel-injected four-stroke motorcycles. In addition, various catalysts were inserted into the motorcycles' tailpipes to determine the characteristics and performance of the catalysts in treating the exhaust.Compared to using RF, we found that using blended fuel potentially reduced the CO and HC emissions by 30-37% and 19-28%, respectively. New catalytic systems, in conjunction with using different fuels, reduced CO, HC, and NO x emissions in the tailpipe exhaust by 12-61%, 32-39%, and 81-85%, respectively. The CO and HC emissions were directly proportional in quantity to the running mileage of the catalyst, but the NO x emissions were unaffected by this mileage, although they increased as the catalyst aged.We also discovered that at identical running mileages for a catalyst, the fuel consumption increased by -1.7-6.5% and 4.1-15% when using E15 and E30 fuel instead of RF. Furthermore, the specific surface area and pore volume of the catalyst decreased with the aged catalyst the phosphorus and sulfur content in the catalyst increased with the catalyst's running mileage; adding ethanol to the fuel decreased emissions of paraffins, olefins, and aromatics but increased those of carbonyls; and the ozone formation potential of volatile organic compounds (VOCs) in the tailpipe exhaust was 16.7-17.2% for paraffins, 22-33% for olefins, 26-45% for aromatics, and 4.9-25% for carbonyls.
