The given graph shows the nitrogen oxide emissions produced by four vehicles. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The line graph illustrates the amount of nitrogen oxide emitted by 4 different means of transport at various speeds.
It is clear that
buses took up the largest percentage of nitrogen oxide emissions, followed by lorries. Meanwhile, diesel and petrol cars were more environmental-friendly. In addition
, the proportion of that emitted by these 2 vehicles also
witnessed stability at any speed.
As can be seen, the amount of NO released by buses was 40g/km
at 10 kph
. It decreased to 25g/km
as buses got faster at 60 kph
but then
rose and reached a peak of over 40g/km
at 130 kph
. Likewise
, lorries created 32.5g/km
at the slowest speed . The figure for that kept dropping to approximately 15g/km
as the lorries' speed got to 90 kph
and increased again to nearly 25g/km
at maximum speed.
By contrast
, petrol and diesel vehicles discharged less emission. The sum of NO emitted by diesel cars remained unchanged at 5g/km
at any speed. Similarly
, cars run on gasoline also
produced a stable total, which stood at 10g/km
