Does a Faulty Three-Way Catalytic Converter Increase Fuel Consumption?

[AsherMarie]

Yes, a damaged three-way catalytic converter increases fuel consumption. Here is some information about the three-way catalytic converter: 1. The three-way catalytic converter primarily affects vehicle emissions. Lower emissions indicate more complete fuel combustion and better fuel efficiency. When the catalytic converter is damaged, gasoline cannot burn and be utilized efficiently, naturally leading to higher fuel consumption. 2. The function of the three-way catalytic converter is to convert harmful gases from vehicle exhaust into harmless gases. The main harmful gases in vehicle exhaust include carbon monoxide (CO), nitrogen oxides (NO), and hydrocarbons (HC). The three-way catalytic converter uses certain chemical agents to undergo a series of chemical reactions with the harmful gases in the exhaust, converting them into harmless gases.
