The chart below shows the nitrogen oxide emissions of four different vehicles at different speed. Summarize the information by selecting and reporting the main features, and make some comparisons where relevant.

The chart compares Nirtogen Oxide emissions (g/km)of four different vehicles at different speeds, highlighting distinct trends. As seen in the graph, Diesel Cars declined further to roughly Diesel and Gasoline cars are the lowest emissions with the speed of 5 and 12.5 (g/km) respectively. The trucks show Nitrogen oxide emissions approximately 32.5 (g/km) at 10 […]
