MD-VMAS (Mustang Dynamometer’s Emissions Vehicle Mass Analysis System)

Mustang’s MD-VMAS allows you to expand your capabilities:
• Measure emissions while running EPA drive cycles
• Tune vehicles more accurately under steady state conditions
• Ensure after market, bolt-on products do not increase emissions .

Mustang Dynamometer’s Emissions Vehicle Mass Analysis System (MD-VMAS) which measures mass emissions in real-time for pre-cert CARB EO testing. Now Mustang dyno owners can add emissions testing that measures and records grams per mile for tailpipe emissions, integrating core Mustang technologies into the basic system, which has been a standard for idle-state, loaded mode and transient emissions-based testing. MD-VMAS simultaneously measures raw concentrations, diluted exhaust flow and dilution ratio, performs the required calculations to generate mass emissions rates and cumulative mass of CO, CO2, NO, NO2, and HC (as hexane), saving the data on a second-by-second basis for instant inspection and analysis.

The heart of the system is comprised of Sensors’ NDIR, NDUV and flow measurement technologies. The Automotive Microbench (AMB II) is employed for the measurement of CO, CO2, and HC exhaust constituents. NDUV technology has been integrated for the measurement of NO and NO2, which is a more accurate, precise and responsive analytical technique. Finally, the vortex flow measurement device has been replaced with a more robust, accurate and wide-ranging averaging pitot technique. The result is a complete system with greater accuracy and reliability.
