Decreasing air pollution concentrations from Internal Combustion Engine (ICE), especially agricultural machines and transporters, is more interested. The current treatment methods have many disadvantages, such as low treatment efficiency, high cost, and complex operation. Therefore, in this study a gas pollution treatment model from ICE by using cold-Plasma is designed and manufactured to solve above problems. MAHA Emission testers for Diesel and Gasoline at the Center motor vehicle registration 50-06V at HCM city are used for results evaluation. The results show that the treatment efficiency of CO, CO2, HC and NOx are about 97%, 95%, 34% and 22%, respectively. The model is portable 260x400x140mm, 8kg and plugin 110V/50Hz or 12 V DC.
