Engine emissions, research, development, and testing services for the automotive and engine manufacturing industry

Intertek’s engine research, development, and emissions testing services perform engine emission testing programs for engine manufacturers and their suppliers. Engine emission evaluations are performed for customers including heavy-duty OEMs, passenger car OEMs, off-road and industrial equipment manufacturers, military, and tiered suppliers.

Our San Antonio, Texas, lab has CARB (California Air Resources Board) recognition, indicating our capabilities include the heavy-duty diesel engine transient federal test procedure, steady-state testing with a ramped modal cycle (SET/RMC), not to exceed (NTE) test procedures, hybrid powertrain testing, and much more.
