Tank-to-wheel emissions from articulated steered wheel loaders
Paper i proceeding, 2018

Performing a comprehensive emission accounting via monitoring equipment to survey the performance of machinery is often an intensive work and costly. This often requiring hours of measurements and a sufficient number of observations to obtain valid findings. The purpose of current work is to introduce a screening emission accounting as a way to have a quick overview of emissions associated with non-road mobile machinery by having a simplified assessment method. To meet this aim, this study uses documented data from performances of machinery and couples them with the recently published guidebook by the European Emission Agency. To map the results, operational performances of four wheel loaders operating in quarries to move stone materials are used, equipped with Stage IV engines and net power output in a range between 130 ≤ kW < 560. The obtained results showed that the positive correlation between an increase in fuel consumption and exhaust emissions is not changed. The mass of emissions, however, is better addressed if emissions are linked with the efficiency of equipment, instead of effective hour. Machinery that consumed less fuel per m3 moved volume of materials, resulted in having less emissions compared to those that had higher fuel consumption per m3 moved volume.
