This report summarizes the results of an experimental study assessing the real-world environmental performance and its comparison with laboratory measurements of two Euro VI step C Refuse Collection Heavy-Duty Vehicles. The first is equipped with a common-rail Diesel engine, a Selective...

Emission inventories play a crucial role in identifying the primary sources of atmospheric pollution. In urban environments, including Addis Ababa, elevated concentrations of vehicle emissions pose significant environmental risks. Consequently, measuring vehicle emissions becomes imperative for...

This report analyses the factors influencing fuel consumption and CO2 emissions of passenger cars in real-world operating conditions. Their effect generates the divergence between the officially reported fuel consumption and the one experienced by the drivers.

Transport is a key factor in modern economies. However, the EU transport system is currently not sustainable, and in many respects moving away from sustainability rather than towards it. The European Environment Agency highlights in particular the sector's growing CO2 emissions that threaten the...

In the diesel sector, engine technology is in continuous development and a number of after-treatment systems have been found which in combination with an enhanced fuel quality reduce emissions of PM, such as the oxidative catalyst and the particle trap. Today, the oxidative catalyst is...
