Does the Three-Way Catalytic Converter Affect Power and Fuel Consumption?
1 Answers
The three-way catalytic converter affects power and fuel consumption. The three-way catalytic converter is a component installed at the front section of the car's exhaust pipe, designed to purify exhaust gases. After the car's exhaust gases are emitted, they pass through the three-way catalytic converter, which reduces the content of harmful substances in the exhaust. If the three-way catalytic converter is damaged, it can cause the car's exhaust emissions to exceed standards, thereby affecting power and fuel consumption. Below are common symptoms of three-way catalytic converter failure: Increased engine fuel consumption: When the three-way catalytic converter begins to clog, it affects the normal operation of the oxygen sensor, leading to inaccurate control of fuel injection, air intake, and ignition, which in turn increases fuel consumption. Decreased car power: When high-pressure exhaust is required, clogging can cause poor exhaust flow, affecting the air intake volume, which results in reduced engine power, decreased performance, and sluggish acceleration. Engine shaking and stalling: In cases where the three-way catalytic converter is completely blocked, the inability to expel exhaust gases in a timely manner inevitably causes backpressure and reverse flow, leading to engine shaking, gasping, and eventually stalling.
