The emissions system is a vital unit of your vehicle that helps to reduce harmful pollutants and emissions that can be detrimental to the environment and human health. The system is made up of several components that work together to ensure that your vehicle is running cleanly and efficiently.
What Parts Make Up the Emissions System?
The exhaust manifold is a component that is attached to the engine's cylinder head and collects exhaust gases from the engine. It is designed to direct the gases to the catalytic converter, which is the next component in the emissions system.
The catalytic converter is an impressive part of the emissions system that you've probably heard before. It helps to reduce harmful pollutants and emissions. It is designed to convert harmful gases like carbon monoxide and nitrogen oxides into less toxic substances like carbon dioxide and water vapor.
The oxygen sensor is a component that monitors the oxygen levels in the exhaust and sends a signal to the vehicle's computer to adjust the air-fuel ratio. The sensor helps to ensure that the motor is running efficiently and that emissions are limited.
The EGR (Exhaust Gas Recirculation) valve is a component that redirects a portion of the exhaust gases back into the engine's intake system. This helps to reduce nitrogen oxide emissions by lowering the combustion temperature.
The PCV (Positive Crankcase Ventilation) valve is a component that helps to reduce harmful emissions from the engine's crankcase. It is designed to vent excess pressure and gases from the engine to the intake system, where they can be burned off.
- Evaporative Emissions Control System
The evaporative emissions control system is designed to reduce harmful emissions from the fuel system. It includes components like the charcoal canister, fuel tank pressure sensor, and purge valve, which work together to prevent fuel vapor from escaping into the atmosphere.
Regular maintenance and repair of your emissions system components is necessary to ensure you are running a safe vehicle. If you have any questions or concerns about your vehicle's emissions system, please reach out to the friendly and professional team at Gowen's Automotive Repairs.
