Our performance and emissions test cells are ideal for your next emissions certification or on-board diagnostics program. Our emissions test cells are full transient capable with low inertia motoring A/C dynamometers. Our chilled fluid system and rapid cooldown capabilities make it easy to perform multiple development tests per day. Our test cells perform projects ranging from mechanical development, validation, certification, and OBD testing. We offer high speed data acquisition systems, wireless torque flanges, accelerometer systems, and full combustion analysis with crank-angle based data acquisition and in cylinder pressure transducers. Our measurement systems are flexible to include customer-based engine control system parameters and CAN messaging. Test cells include 24-hour video access and remote calibration management. We have an FTP server to provide real time data and analysis.
