Short summary
The authors conducted the measurement of real-world CO2 and NOx emissions from one heavy-duty vehicle. The results showed that NOx emissions increased in colder seasons because of the deactivation of after-treatment tools. We proposed an estimation model of vehicle emissions based on the classical mechanic theory. The model explained the emission behavior of CO2 and NOx well, and thus, we concluded that the proposed model will be applied to the evaluation of vehicular emission inventories.
