Does the Absence of a Catalytic Converter Affect Fuel Consumption?

[Jodie]

The absence of a catalytic converter does not affect fuel consumption. From the entire working process of the catalytic converter, its primary responsibility lies in exhaust gas treatment, and therefore, it has no connection with the vehicle's fuel consumption. Precautions for Using a Catalytic Converter: Apart from failure, a catalytic converter may also become clogged. If the catalytic converter is clogged, the engine may experience insufficient power and increased fuel consumption, which requires attention. Removing the catalytic converter can significantly affect the engine's low-end torque, and during daily driving, higher RPMs may be required to compensate for this deficiency, which indirectly increases fuel consumption. If the catalytic converter is removed, the reduction in exhaust pressure will ultimately lead to a decrease in the vehicle's low-end torque. Factors Affecting Vehicle Fuel Consumption: Vehicle Weight: There are many factors that affect fuel consumption, the first being the vehicle itself, such as its weight. The heavier the vehicle, the higher the fuel consumption. Tire Pressure: Low tire pressure increases fuel consumption. Engine: Dirt and oil buildup on the engine's surface can affect heat dissipation, leading to increased fuel consumption. Transmission Carbon Buildup: Carbon buildup in the transmission can reduce engine power and, to some extent, be accompanied by increased fuel consumption.
