Abstract
Improving the gasoline fuel combustion, reducing gasoline fuel consumption and reducing vehicles exhaust emissions pollution associated with gasoline combustion become growing interest locally and ...
Highlights
With growing concerns about the contribution of transportation sector’s to climate change, many vehicle manufacturing companies are looking to deploy high compression and more efficient engines that have greater fuel economy and emit less carbon dioxide (CO2)
The study results indicated an impact of the gasoline fuel quality on fuel consumption, air-fuel ratio (AFR), lambda (λ) and exhaust emissions
Gasoline fuel with higher octane number burns cooler, which mean less oxidation of nitrogen already exists in the air mixed with the gasoline fuel in the combustion chamber and produces lower levels of nitrogen oxides (NOx) exhaust emission
Summary
With growing concerns about the contribution of transportation sector’s to climate change, many vehicle manufacturing companies are looking to deploy high compression and more efficient engines that have greater fuel economy and emit less carbon dioxide (CO2). The use of high compression engines has been obstructed by the low gasoline octane rating. This increases the possibility of engine knock, wherein gasoline self-ignites and explodes, reducing vehicle efficiency and performance. In order to overcome this issue, vehicle manufacture companies have called on the US Environmental Protection Agency (EPA) to adopt regulations to increase levels of gasoline octane. In the absence of federal action, states may wish to adopt their own regulations (Webb, 2017)
