Catalyst aging services from SGS – significantly reduce your catalyst aging time and associated costs with our patented C-FOCAS® and natural gas burner technology.

Highway in the dark

To support your automotive catalyst testing program, you need state-of-the-art technology, precise testing and data, and fast results. Our catalyst aging services utilizes our patented C-FOCAS® and natural gas burner technology to help significantly reduce aging costs and over-temperature conditions for OEMs and suppliers. We also provide burner manufacturing, engineering services, and support for your aging program.

Why choose catalyst aging from SGS?

We can help you:

  • Age full-sized automotive catalyst systems rapidly and precisely
  • Simulate the flow of exhaust gas from an engine under a variety of load conditions
  • Gain aging for three-way catalysts, using gasoline, natural gas, and propane fuels with our stoichiometric combustion systems
  • Accurately inject oil or metered poison to simulate engine oil consumption
  • Benefit from independent control of thermal effects and the effects caused by lubrication oil poisoning
  • Age catalysts with or without oil poisoning effects
  • Precisely control catalyst aging temperature with less variation and to higher extremes than can be obtained from an engine-based system for higher reliability
  • Simulate high-engine exhaust temperatures and maximum flow-rates with hot gas burners (temperatures and flows can be cycled to accelerate thermal-cycling)
  • Simulate how an oil leak can alter the aging for a catalyst
  • Correlate our C-FOCUS® burner to pre-existing aging cycles as well as further develop the cycle to higher temperatures in order to reduce the overall time and cost of your aging program

Why SGS?

As a world-leading provider of testing, inspection, certification and verification for the transportation industry, we offer you unrivaled expertise in catalytic aging and our patented C-FOCAS® system.

What is C-FOCAS®?

C-FOCAS® is our computer controlled, gasoline-fueled, burner-based exhaust catalyst aging system. It has been developed to provide accelerated aging to shorten test times and reduce costs through fuel savings. Unlike engine-based aging, where oil consumption is inherent to engine operation and changes with engine wear, the system consumes no oil during fuel-air combustion. Lube oil may be injected into the hot combustion products with a metering and measurement system.

Because of its controlled combustion process, the burner-based system is not susceptible to engine-related failure modes that can cause misfires and uncontrolled catalyst exotherms. The result is fewer failures of expensive prototype catalysts. Unlike an engine, the multi-catalyst burner easily operates at temperatures exceeding 1200°C.

The C-FOCAS® aging system has been correlated to numerous aging specifications including RAT-A, ZDAKW, SBC, four-mode aging, and several proprietary OEM cycles. The result is significant reduction in both overall cycle time and fuel consumption with improved quality.
