Emissions

HOW CAN WE HELP YOU?

We set the bar with new methodologies of characterizing engine exhaust constituents for vehicles of all sizes and fuel types. We are a global leader in the measurement of particulate emissions. Our specialists engage clients with certification and audit testing services. Homologation programs are primarily heavy-duty on-highway and non-road diesel, gasoline, and alternatively fueled engines to conformance with applicable EPA, CARB, ECE EURO or other regulatory requirements. Manufacturer self-audit and EPA Selective Enforcement Audit (SEA) support programs are also performed. We pioneered measurement of engine and vehicle exhaust emissions and development of measurement techniques.
