【 摘 要 】

Fossil fuel-powered vehicles are the most significant contributor to air pollution nowadays. They emit substances that are harmful to both human and environment. Carbon monoxide (CO) and Hydrocarbon (HC) is the most common harmful exhaust gases found in the environment. One of the technologies used for reducing CO emissions is catalytic converters. The catalytic converters usually installed in the exhaust system. The numeric study was conducted on the interaction of flow, reaction, and thermal effects in the form of a 2D model of the catalytic converter. Simulation using Fluent software was then used to find out the extent of the catalyst effects on CO gas absorption when velocities were 6.3 m/s, 15 m/s, and 20 m/s. The simulation revealed that CO mass fraction and temperature around the exhaust channel increased as the velocity increased.
