The graph below describes how vehicle type and speed affect nitrogen oxide emissions. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph illustrates nitrogen oxide emissions by speed affects and vehicle types. Overall, it can be seen that 4 different groups was an increased,dicreased and also maintain the same level.The most significant increase type was large transports such as buses and lorries.Nitrogen oxide emissions from petrol and diesel cars remained relatively stable regardless of […]

The given chart demonstrates how a variety of vehicles emit different amounts of nitrogen oxide depending on their speed. The speed and emissions are recorded at kilometers per hours and gallons per kilometer respectively. It is evident that buses have the largest amount of emissions while diesel cars have the least. Buses highest emissions are […]
