The information about the emissions of nitrogen oxide from diesel cars, petrol cars, lorries and buses, is depicted by the rendered line graph. The data has been calibrated in ‘x’ axis (speed kilometer per hour) and in ‘y’ axis (g/km).
To cap it all, it can be vividly seen that buses and lories follow a similar trajectory, whereas diesel and petrol cars show a same pattern. Moreover, buses produce the maximum number of emissions.
In terms of buses and lories, at the speed of 10 kph, while buses are producing 40 g/km, around 33 g/km releases from lories. As the speed progresses, there is a dramatic decline show in nitrogen oxide discharges, decrease to 40 g/km from buses when speed is 60kph, and drop to approximately 16 g/km from lorries. The number of fumes produces from these two vehicles start to rise again, peak at 41 g/km from buses when speed rise to 130 kph, at the same speed lorries produce exhaust about 29 g/km.
On the other hand, gases from diesel cars are the least and hover around 5 g/km over the given speed, whereas lories produce roughly 10 g/km. Interestingly, both types of car do not show much variation in emissions.
