Australia: Light-duty: Diesel CUEDC

Overview

This page contains information about the Composite Urban Emissions Drive Cycles (CUEDCs)—a collection of non-regulatory test cycles developed and used in Australia. Development of the CUEDCs was commissioned by the Australian National Environment Protection Commission in 1998 as part of the Diesel National Environment Protection Measure. Data was collected in Sydney, Australia. In 2005, a Petrol CUEDC was developed for light-duty gasoline vehicles.

Description

CUEDCs were created with the intention to closely replicate actual Australian on-road urban driving. CUEDCs are used for chassis based dynamometer testing of both heavy and light vehicles. They are composed of four distinct drive cycle segments: congested, minor roads, arterial and highway. A set of the four CUEDC segments takes a total of about 30 minutes.

Different CUEDCs were developed for each of the major diesel powered vehicle categories ranging from off-road passenger vehicles and light goods vehicles to heavy combination vehicles. There are six CUEDC cycles, one for each of the six ADR vehicle categories: MC, NA, NB, ME, NC, NCH.
