    ANALYSIS OF THE TEMPERATURE PULSATIONS OF THE EXHAUST GAS BEFORE THE THREE-WAY CATALYST

  • Original language description

    When using combustion engine such as common gasoline engine, exhaust gas temperature pulsation due to dynamic changes in the operation condition often occurs. The most problematic point in designing the aftertreatment system is the light-off temperature of the three-way catalyst. The aim of this article is to describe the effect of the load and speed of the engine, which are the most problematic and frequently changing conditions during the real drive. A simulation of the exhaust gas temperature was carried out in order to investigate the impact on the effectivity of the catalyst. The simulated engine was inspired in turbocharged engine VW 1,5 TSI EVO. The exhaust gas temperature was calculated for full load steady state conditions, no load steady state conditions and real drive transient conditions. The results show that the effect of the dynamic changes of the load and speed of the engine is significant for determine the temperature pulsations in exhaust gas. These pulsations have major effect on the effectivity of the catalyst. Next research will be focused on remove these disadvantages with usage of heat storage system based on PCM materials inserted between the turbine and the catalyst.
