Comparison of performance and emission characteristics between ceramic and metallic catalytic converter
Catalytic converters have been widely used on vehicles and have already been proved for many years to be the most effective technical solution to reduce exhaust emissions from gasoline engines where ceramic and metallic catalytic converters are the most common types of catalytic converter used.

| description | Catalytic converters have been widely used on vehicles and have already been proved for many years to be the most effective technical solution to reduce exhaust emissions from gasoline engines where ceramic and metallic catalytic converters are the most common types of catalytic converter used. This study focuses to examine the performance of ceramic and metallic catalytic converters through simulation and experimental in terms of flow distribution and pollutant gases conversion. ANSYS Fluent 16.2 has been used for the simulation process and Mitsubishi 4G93 1800cc gasoline engine with difference speed and 25% constant load were used for the emission measurement using Kane Auto 5-1 series exhaust gas analyser. Simulation process has been conducted to measure pressure, velocity and temperature distribution through the ceramic and metallic catalytic converter and for the experimental process, the performances and pollutant gases conversion were recorded to compare both type of catalytic converters. Based on the simulation results, ceramic honeycomb catalytic converter shows higher pressure distribution 181.1 Pa on the inlet region compares to metallic sinusoidal. On the other hands, metallic sinusoidal catalytic converter has better velocity distribution of 14.3 ms- 1and temperature distribution of 1100 Kat the inlet region. Through the experimental results, metallic sinusoidal catalytic converter performs a better reduction of CO compares to ceramic honeycomb catalytic convetier while ceramic honeycomb performs better reduction than metallic sinusoidal catalytic converter for HC and NOx conversion. It can be concluded that metallic corrugated catalytic converter has performs better flow distribution through the substrates while ceramic converters reduce a higher percentage of CO and NOx pollutant gases. |
