Band 4+: The given graph shows the nitrogen oxide emissions produced by four vehicles. Summaries the information by selecting and reporting the main features and make comparisons where relevant.

Image for topic: The given graph shows the nitrogen oxide emissions produced by four vehicles. Summaries the information by selecting and reporting the main features and make comparisons where relevant.
Our system will evaluate the answer based on this AI-generated description.
The image displays a line graph with speed in kph on the x-axis ranging from 10 to 130 in increments of 10, and nitrogen oxide emissions in (µg/km) on the y-axis ranging from 0 to 45 in increments of 5. There are four lines representing different vehicles: diesel cars with the highest emissions starting at 40, peaking at 42 around 50 kph, decreasing to 30 at 90 kph, rising back up to 35 at 130 kph; petrol cars starting at approximately 10, rising to a peak of 15 at 50 kph, falling to 5 at 90 kph and ending at 10 at 130 kph; lorries beginning at about 35, peaking at around 38 at 50 kph, dropping to 30 at 90 kph, and concluding at 35 at 130 kph; and buses starting at approximately 25, peaking just above 30 at 50 kph, decreasing to around 20 at 90 kph, and finishing at 25 at 130 kph.
Given the complexity of the image, the above description may not be entirely accurate.

The given line graph illustrates the amount of nitrogen oxide emissions released by selected four types of vehicles.

It can be seen that the emissions of buses and lorries are higher while remaining two vehicles produce constant and low amounts of nitrogen oxide.

At the starting speed of 10kph, buses produce largest amount of around 40g/km with lorries follow the second place of around 33g/km. With the same speed from above, petrol car and diesel car release smaller amount of over 10g/km and around 7g/km respectively. After that, the emissions produced by four vehicles all have a downward trend. Buses reach the bottom point of emissions, around 26g/km at the speed of 60kph, while lorries meet its lowest point of over 15g/km with the speed 90kph.

Following this, buses emit an increasing amount of gas with faster speed till highest point of over 40g/km at the speed of 130kph. And lotties emission also have a swiftly climb till around 24g/km at the final speed.

When we look closer to other two vehicles, the petrol car have a steady and fluctuate changing amount of emissions produced just around 10g/km. In diesel car, the amount of emissions have a unnoticeable fall to 5g/km at the speed of 70kph and remain unchanged till the final speed of 130kph.
