Cleaire Advanced Emission Controls has opened of their Heavy-Duty Chassis Dynamometer Emissions Laboratory for outside contract services. This lab, Cleaire Advanced Technology Testing Services (CATTS) is located in Richmond, California, on the campus of the Chevron Technology Center.
The laboratory, which a CFR-compliant heavy-duty chassis dynamometer, is capable of testing a variety of medium and heavy-duty power train technologies including diesel emission control systems, hybrid power trains and alternative fuels.
The chassis dynamometer consists of a Froude-Consine transient motoring dynamometer capable of full road-load and wind simulation, with power absorption sufficient to test any vehicle up to 575 horsepower. This allows the lab to accommodate transient driving schedules like the Urban Dynamometer Driving Schedule (UDDS), New York City Bus (NYCB), or virtually any other driving cycle in addition to steady state tests.
The lab features a full scale insulated dilution tunnel for both continuous and bag measurements of nitrogen oxide, nitrogen dioxide, carbon dioxide, carbon monoxide, and total hydrocarbons, as well as the ability to integrate other gaseous pollutant measurements. A secondary dilution system allows for measurement of particulate matter (PM) over a test cycle. A coriolis mass flow sensor provides fuel consumption and fuel economy.
CATTS can handle vehicles ranging from pickup trucks to Class 8 trucks, buses and other heavy duty vehicles, single or tandem axle drive with inertia simulation from 6,000 to 85,000 pounds.
Cleaire Advanced Emission Controls has used the lab since 2002.
