What Happens If a Car Doesn't Have a Catalytic Converter?

[DeCourtney]

If a car doesn't have a catalytic converter, the oxygen content at the front and rear ends will be the same. The oxygen sensor will send a signal to the electronic control unit indicating excessive oxygen content, which the unit will interpret as a lean air-fuel mixture. As a result, it will increase fuel injection, making the mixture too rich and thereby increasing the car's fuel consumption. A catalytic converter is typically installed at both the front and rear of a car to monitor the oxygen content in the exhaust. When functioning properly, the oxygen content at the front end is higher than at the rear end, making it inadvisable to operate without a catalytic converter. The catalytic converter is a crucial external purification device in a car's exhaust system. It converts harmful gases such as CO, HC, and NOx from car exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. Known for its stable performance, reliable quality, and long lifespan, catalytic converters are widely used in models from Toyota, Honda, Buick, Audi, Volkswagen, Hyundai, Suzuki, and Changhe.
