Drive Cycle and Short Test Development report
Department of the Environment and Heritage, September 2005
The Department of the Environment, Water, Heritage and the Arts is the lead Australian Government agency responsible for a major study of the emissions from petrol engine vehicles. It is important for government to have current, robust emissions data for the purposes of emissions modelling, and to inform policy development for vehicle emissions management.
Vehicle emissions modelling is important when developing strategies to manage emissions, analyse and assess proposed strategies to manage and improve urban air quality. In the absence of robust Australian data, modellers are forced to rely on overseas data that may not be valid for Australian conditions. In 2005 a new Australian Petrol Composite Urban Emissions Drive Cycle (CUEDC) was developed for NISE2. The CUEDC aims to represent real-world Australian driving conditions in the laboratory with the sample vehicle operated on a dynamometer.
The full testing phase of the study began in December 2007. Approximately 350 petrol vehicles manufactured from 1994 to 2007 will be tested over a period of 12 months. The results are expected to provide up-to-date vehicle emissions factors for the current petrol fleet and will demonstrate the changes in emissions technology since NISE1 was conducted in 1996. Unlike NISE2, that study did not include imported cars, four wheel drives or light commercial vehicles.
