Summary:

For the reduction of greenhouse gas emission in thetransportation sector, various countermeasures against CO₂ emissionhave been taken. The eco-driving has been paid attention because ofits immediate effect on the CO₂ reduction. Eco-driving is definedas a driving method with various driving techniques to save fueleconomy. The eco-driving method has been promoted to the commondrivers as well as the drivers of carriers. Additionally, there aremany researches about improvement of fuel efficiency and CO₂reduction. However, the eco-driving will have the reduction effectof CO₂ emission, the influence of the eco-driving on air pollutantemission such as NOx is not yet clear.In this study, the effect of the eco-driving on real-worldemission has been analyzed using the diesel freight vehicle withthe on-board measurement system. In the test, two drivers drove theone diesel freight vehicle in the same route; one driver drove thevehicle normally, and another one drove it with the early shift-updriving. The CO₂ reduction effect by the early shift-up driving wasexamined, as the same time, NOx emission behavior was comparedbetween the driving with and without the early shift-updriving.As a result of the on-road driving test under the urban drivingcondition, the early shift-up driving had a sufficient effect onCO₂ reduction and fuel efficiency improvement. However, the earlyshift-up driving caused an increase of NOx emission. This result islargely concerned with the engine operating region, such as enginespeed and engine torque
