Description

Developing high-performance engines and catalytic converters with low fuel consumption and ultra-low emissions requires emission measurement systems that are very fast, sensitive and precise.

The V&F MotoSense gives engine and catalyst researchers a tool for investigating organic hydrocarbons and inorganic nitrogen or sulfur emissions in exhaust gas. Response times of 20 ms and a dynamic measuring range of 1 to 10^4 allow transient processes to be studied precisely.

Typical applications

  • Measurement of hydrocarbons (unlimited)
  • Monitoring of desulfation strategies in catalytic converters
  • Ammonia and NOx measurements on SCR catalysts

Application examples

Automotive industry

  • Ammonia and NOx measurements in engine exhaust gas
  • Desulfation strategies for catalytic converters

Measurable compounds

  • Nitrogen compounds: NH3, NO, NO2
  • Sulfur compounds: H2S, COS, SO2, CS2
  • Hydrocarbons: CH4, C2H2, C2H4, C3H6, C4H6 (butadiene), C6H6, C7H8, C8H8 (styrene), C8H10 (xylene), C4H8 (butylene), C5H10, C6H12 (cyclohexane), C7H14 (methylcyclohexane), C8H16, C9H18, C10H20

Values marked as application-dependent (measuring range, response time, detection limit, gas consumption) depend on the compounds measured, the system configuration and the instrument settings.
