Emissions of Nitrogen Dioxide from Modern Diesel Vehicl

work and others suggests that modern gasoline powered vehicles emit less than 1% of their NOx as NO2. For instance, Heeb et al measured emissions of twenty Euro III and Euro IV gasoline powered vehicles in a dynamometer based study [7]. Using high-speed sampling and a mass spectrometric analytical method, they arrived at the same conclusion.

Exhaust gas - Wikiped

Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline, petrol, biodiesel blends, diesel fuel, fuel oil, or coal.According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle.It often disperses downwind in a pattern called an exhaust plume.
