Emission Checks: How They Point Out Problems in Your Vehicle

Emission Checks Advantages, Atlanta | Atlanta Car Care

The benefits you can get from a simple emissions check are quite a lot but this fact is not as widely spread as it should be. That's the exact reason we will talk about emission checks in today's blog. Let's get right into the matter and start off with a simple explanation about what this procedure actually is:

What is A Emission Check

Emission checks involve analyzing the gasses and pollutants emitted by a vehicle's exhaust system. By measuring the concentration of specific emissions, inspectors can assess the vehicle's compliance with established emission standards. However, as we mentioned above, emission checks do more than just assess environmental impact; they can also identify potential problems within the vehicle's engine and emission control systems.

Detecting Engine Performance Issues

  Malfunctioning Oxygen Sensors

Oxygen sensors play a crucial role in monitoring the air-fuel mixture in the engine. Emission checks can reveal if the oxygen sensors are malfunctioning or providing inaccurate readings, which can lead to inefficient fuel combustion and increased emissions.

  Faulty Catalytic Converters

Emission checks can identify issues with the catalytic converter, a vital component that reduces harmful pollutants. A failing catalytic converter may result in increased emission levels, indicating the need for repair or replacement.

  Misfiring Cylinders

Emission checks can detect engine misfires by analyzing the exhaust gasses. Misfires can lead to incomplete combustion, resulting in increased emission levels and reduced engine performance. Identifying misfiring cylinders allows for targeted repairs or tune-ups to restore optimal engine operation.

  Evaporative Emission Control System Problems

The evaporative emission control system prevents fuel vapors from escaping into the atmosphere. Emission checks can uncover issues with components such as the gas cap, charcoal canister, or purge valve, which, if faulty, can lead to increased emissions and fuel evaporation.

Identifying Emission Control System Malfunctions

  Exhaust Gas Recirculation (EGR) System Problems

The EGR system reduces nitrogen oxide (NOx) emissions by recirculating a portion of the exhaust gasses back into the combustion chamber. Emission checks can flag problems with the EGR valve, such as clogging or malfunction, which can impact engine performance and emissions.

  Positive Crankcase Ventilation (PCV) System Issues

The PCV system regulates the flow of gasses from the engine's crankcase. Emission checks can reveal if the PCV valve is clogged or malfunctioning, leading to increased emissions and potential engine damage.

  Air Injection System Malfunctions

The air injection system introduces fresh air into the exhaust stream to promote complete combustion. Emission checks can identify issues with components such as the air pump or diverter valve, which, if not functioning correctly, can result in increased emission levels.
