Operating a vehicle with a malfunctioning emissions control device can lead to several issues, including decreased fuel efficiency, performance problems such as reduced acceleration and rough idling, and the potential for failing mandatory emissions tests. A damaged unit may also trigger warning lights on the vehicle’s dashboard. For instance, a glowing “check engine” light may illuminate. In extreme cases, a severely compromised device can overheat, potentially leading to fire hazards.
A properly functioning emissions control device is crucial for environmental protection. It converts harmful pollutants in exhaust gases into less harmful substances, contributing significantly to cleaner air and reduced smog. Regulations regarding these devices exist in many jurisdictions, reflecting their importance for public health and environmental well-being. The development and implementation of these devices have been instrumental in reducing vehicle emissions over the past several decades.
