Emissions Control Systems Overview
This section provides an overview of the emissions control systems in the 2015-Present Audi Q7, including the components and their functions. It explains how the emissions sensors integrate with the overall system to ensure compliance with emissions standards.
Emissions Control Components
- Catalytic Converter: Reduces harmful emissions by converting pollutants into less harmful gases.
- Diesel Particulate Filter (DPF): Captures and regenerates soot particles from diesel engines.
- Selective Catalytic Reduction (SCR): Reduces nitrogen oxide emissions by injecting a reducing agent.
- Exhaust Gas Recirculation (EGR): Reduces nitrogen oxide emissions by recirculating a portion of the exhaust gas.
- Oxygen Sensor: Measures oxygen levels in the exhaust gas to optimize fuel injection.
- NOx Sensor: Monitors nitrogen oxide emissions to ensure compliance with emissions standards.
Sensor Locations and Functions
- Oxygen Sensor: Located before and after the catalytic converter to monitor oxygen levels.
- NOx Sensor: Positioned upstream and downstream of the SCR system to monitor NOx levels.
- Exhaust Temperature Sensor: Mounted near the DPF to monitor temperatures during regeneration.
- Exhaust Pressure Sensor: Located near the DPF to monitor pressure and detect blockages.
- EGR Temperature Sensor: Monitors the temperature of the recirculated exhaust gas.
