This component, specific to certain vehicle models, is part of an emissions control system designed to reduce harmful pollutants during engine start-up. It functions by injecting fresh air into the exhaust stream, facilitating the oxidation of hydrocarbons and carbon monoxide before the catalytic converter reaches its operating temperature. This assists in meeting stringent emissions standards.
The system plays a crucial role in minimizing the environmental impact of the vehicle, particularly during the initial cold start phase when emissions are typically highest. Proper function ensures compliance with regulatory requirements and contributes to improved air quality. Historically, such systems have evolved in response to increasingly stringent emission control mandates.
