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:
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)
Quick response; 2ms
High linearity; ±1% Full Scale and under (FS: 10%)
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.
