Emissions and Fuel Economy Testing

Millbrook offers exhaust emissions and fuel economy testing, including electric vehicle range and energy consumption measurement, to a global automotive customer base.

Its vehicle emissions test facilities are operated independently and impartially, and are designed to suit the full range of vehicles, - from passenger cars to commercial vehicles.

Millbrook's 4WD climatic emissions chassis dynamometer facilities include individual climatic soak rooms and can be used in conjunctio with Millbrook's correlated Portable Emissions Measurement Systems (PEMS). They support the delivery of legislative and tailored drive cycles, including real diving emissions (RDE) cycles, and global powertrain calibration and certification.

 

 

Millbrook 4WD Climatic Emissions Chassis Dyno Emissions Testing Facility

Millbrook offers two large emissions chambers in the UK - a Variable Temperature Emissions Chamber (VTEC) and a Heavy Duty Dynamometer Test Chamber (HDDTC). These are ideally suited for a variety of vehicle and emissions tests on light and heavy duty vehicles.

Millbrook's VTSHED is used for evaporative emission permeation testing.

Engine Testing

Millbrook offers 28 engine test cells which cover a diverse range of capabilities.

Typical applications include engine and driveline durability testing, engine development work, turbocharger testing, NVH investigations and CEC fuels testing.

Millbrook performs fuel blending of volumes up to 1,000L and has bulk and special fuels capability, inlcuding bio fuel and E100. Component strip and rate service for post-test inspection is performed by a highly experenced team using state-of-the-art facilities.
