Bus emissions test cycle in Millbrook's Variable Temperature Emissions Chamber (VTEC) built to carry out heavy duty vehicle tests

Bus Emissions Test Cycles

The Millbrook London Transport Bus (MLTB) test cycle used by Transport for London (TfL) to evaluate bus emissions performance and the national Ultra Low Emission Bus (ULEB) accreditation scheme have now been unified.

The new bus testing procedure is called the UK Bus Cycle (UKBC) and comprises of the London Bus Cycle (LBC) phase (based on the Millbrook London Transport Bus (MLTB) vehicle emissions test cycle) and a rural test phase.

In order to qualify it as an Ultra Low Emission Bus (ULEB), bus manufacturers must test their vehicle over the UK Bus Cycle (UKBC) test procedure. Millbrook has years of experience in bus testing and vehicle emissions testing and is able to perform the full suite of tests required under the UK Bus Cycle (UKBC).

Millbrook conducts emissions and fuel economy vehicle tests on vehicles including passenger cars, buses, coaches, trucks and off-highway vehicles, against many emissions test procedures. These include the new UK Bus Cycle (UKBC), World Harmonized Vehicle Cycle (WHVC), LowCVP UK Coach (LUC), Low Carbon Vehicle Partnership (LowCVP) UK HGV, and European, Federal and Japanese light duty emissions regulations including the Worldwide Harmonised Light Vehicle Test Procedure (WLTP).

The WLTP emissions test can be completed using one of Millbrook’s 4WD climatic emissions chassis dynamometers. Millbrook’s Variable Temperature Emissions Chamber is built to carry out heavy duty vehicle tests against a wide range of drive cycles.
