  • Experiments on temperature field and conversion efficiency of three way catalyst under different engine operation conditions

    • 摘要:

      The effects of temperature field and the substrate average temperature on the three way catalyst (TWC) conversion efficiency under different engine operations were studied on the test rig to analyze its mechanism. The experimental results showed that the temperature difference caused by the chemical reaction, heat and mass transfer in substrate is up to 82 °C. The factor which decides the catalytic process under different substrate average temperature is different, leading the distinct trend of conversion efficiency. All these provides the experimental basis for TWC design and effective calibration between engine and TWC.
