Carbon Dioxide Measuring Technology in Engine Combustion Chambers 2004-01-1340

The authors have developed an instrument that measures the CO2 concentration in engine combustion chambers using the infrared absorption method.
The characteristics of this technology are as follows:
  1. 1
    Measuring can be carried out while the engine is running at 600r/min to more than 3000r/min, full load operation.
    (Applicable to all EGR conditions)
  2. 2
    Quick response; 2ms
  3. 3
    High linearity; ±1% Full Scale and under (FS: 10%)
  4. 4
    No aggravation is caused to the intake/exhaust performance of engines
This technology contributes to the improvement of the in-cylinder EGR system using, for instance, a variable valve-timing mechanism that is now expanding in number of applications, and also the conventional EGR system.
