What Happens If the Car's Catalytic Converter Is Removed?

The function of a car's catalytic converter is to enhance the purification of exhaust emissions. If removed, it will increase the vehicle's exhaust emissions because without the catalytic converter, the exhaust gases cannot be effectively purified, leading to emissions that exceed standards. Additionally, it will reduce the car's power and increase fuel consumption. Below are the reasons for high fuel consumption: 1. Improper driving habits: Fuel consumption is closely related to the driver's habits, such as prolonged idling without turning off the engine or frequent starts, aggressive acceleration or frequent braking, driving at low gear with high speed or high gear with low speed, etc. These driving habits significantly 'contribute' to increased fuel consumption. 2. Abnormal tire pressure and tire wear: Low tire pressure increases friction between the tires and the ground, raising resistance and thus fuel consumption. Normal tire pressure is around 2.5bar, which can be slightly reduced by 0.1bar in summer. Of course, tire pressure should not be too high either; it's best to inflate according to the vehicle's standard values. Moreover, severely worn tires often cause slipping, which also increases fuel consumption. 3. Fuel quality and carbon buildup: Many car owners overlook fuel quality. Poor-quality gasoline increases carbon deposits, which roughens the intake pipe walls, affecting air intake and mixture quality, leading to a sharp rise in fuel consumption. Therefore, gasoline quality should not be ignored. Regular maintenance at a 4S shop is a forward-looking investment, ensuring normal vehicle performance and saving unnecessary future expenses.
