4WD Chassis Dynamometer Emission Testing

The state-of-the-art facility develops and tests systems for control of emissions based on advanced catalytic technology to provide automakers with solutions to meet regulatory requirements including the new U.S. 54.5 mile-per-gallon corporate average fuel-efficiency (CAFE) targets for 2025. New vehicles will be required to meet lower tailpipe emissions under federal Tier 3 standards, as well as California LEVIII requirements.

The improvements to the facility now allow for an array of drivetrains and vehicle platforms to be tested – from diesel trucks and SUVs, to GDI (gasoline direct injection) engines, hybrid cars and even large motorcycles. The expansion will allow catalyst development for all fuels – diesel, CNG and E85, so whichever direction vehicle manufacturers take, the client can support.

Challenge

The client wanted to respond to the increasing demand for light-duty vehicle aftertreatment products, testing and validation.

Solution

ACS designed and built a facility expansion that included:

• 4WD chassis dynamometer test cell, including road speed fan, complete raw and dilute gaseous and particulate emissions measurement capability in compliance with US EPA 1066 regulations
• Vehicle soak area
• 12-vehicle stacker system
• Analytical instrument repair room
• Remodeled building entry foyer
