Description
This study investigated the real-time NOx emissions from a heavy-duty diesel truck and a bulk carrier ship. The test road vehicle was driven on a combination of a flat and hilly route from Brisbane to Toowoomba that covered urban, rural and motorway driving. On-board ship emissions were measured on the sea from the port of Gladstone to Newcastle. NOx emissions from both engines were compared and analysed to understand the influence of engine parameters as well as route variables and power transmission on NOx emissions. Results from these measurements show that truck NOx emissions increased with the engine power and speed however a significant NOx emission can be seen during the idling condition while producing low power. On the other hand, ship NOx emissions followed an approximate cubic relationship as a function of engine RPM that is completely different from that of the truck.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
