Operating a vehicle with a malfunctioning catalytic converter is possible, but discouraged. A catalytic converter reduces harmful emissions, and its failure may lead to increased pollution, failed emissions tests, reduced fuel efficiency, and potentially engine damage. For example, a clogged converter restricts exhaust flow, impacting engine performance.
Maintaining a properly functioning exhaust system, including the catalytic converter, is crucial for environmental protection and vehicle health. Regulations mandate emissions standards that functioning converters help vehicles meet. Historically, the introduction of catalytic converters significantly reduced vehicle-produced smog and air pollution. Their continued effectiveness relies on proper maintenance and timely replacement when faulty.
