Effect of Improving the Gasoline Fuel Quality on Exhaust Emissions from in-use Vehicles - An Experimental Study

In India, two and three-wheelers constitute about 70% of the total in-use vehicle population and consume about 2/3^rd of the total gasoline, rest of the gasoline being consumed primarily by the passenger cars. This paper presents the findings of an experimental study carried out on in-use gasoline vehicles, including two and three- wheelers and passenger cars. The gasoline fuels used for the study were equivalent to Euro-II, Euro-III and Euro-IV fuel quality specifications. The study analyzes the effect of improving the gasoline fuel quality on exhaust emissions from in-use vehicles.
