Band 7: Task 1: (Line Graph) Differing amount of nitrogen oxide by four types of vehicles. (User-Written IELTS Writing Task 1 Sample)

The line graph provides information about the nitrogen oxide emission made by four different types of vehicles(buses, lorries, petrol cars, diesel cars) at various speeds ranging 10 to 130 kilometres per hour.

Overall, it is clear that buses and lorries generate significantly more emission than petrol and diesel cars. Additionally , emissions from heavy vehicles vary noticeably, while those cars remain fairly stable throughout .

Emissions from lorries decreased steadily from 10 to 80 kph , then increased after that point. Buses started with highest levels at 10 kph, and then experienced a sharp rise. These patterns suggest that admission from heavy vehicles are strongly influenced by speed, likely due to engine performance and fuel efficiency.

Petrol cars maintained a steady amount of emission about 10 g/km across all speeds. Diesel cars produced the lowest emission , remaining consistently below 8 g/km. These figures indicate that cars are more friendly to the environment and less affected by changes in speed.
