Fast Response NDIR for Real-Time Exhaust Measurement 900501

The objective of the work was to develop a fast response infrared analyzer that makes possible the cyclic measurement of exhaust gas concentrations from internal combustion engines.

The new analyzer achieves T₉₀ response time of less than 30 milliseconds and is capable of measuring CO, CO₂ and HC (Hydrocarbons) simultaneously.

Another feature of the analyzer is its' capability to measure simultaneously from multiple sample points, i.e., one optical bench with a maximum of four sample cells can measure CO, CO₂ and HC simultaneously from four different sources.

Results from a multiple cylinder engine show that this analyzer can be an effective tool for analysis and diagnosis of internal combustion engine exhaust products.
