EGR Valve on the 2020 Mitsubishi ASX: What You Need to Know

The 2020 Mitsubishi ASX, a popular compact SUV in Australia, is equipped with a range of emission control technologies designed to meet strict environmental standards. One key component often discussed in relation to petrol and diesel engines is the Exhaust Gas Recirculation valve, commonly known as the EGR valve. So, does the 2020 Mitsubishi ASX have an EGR valve, and what role does it play in your vehicle?

The short answer is yes, the 2020 Mitsubishi ASX does feature an EGR valve, particularly on petrol engine variants such as the 2.0L petrol engine that is common in this model. Mitsubishi employs this component as part of the engine's emissions control strategy to reduce nitrogen oxide (NOx) emissions by recirculating exhaust gases back into the engine's intake system. This process helps lower combustion temperatures, which directly reduces the formation of harmful NOx emissions. This makes the EGR valve a crucial part in helping the ASX meet Australian and global regulatory requirements while also improving fuel efficiency and engine smoothness.

So, what exactly does the EGR valve do? When the engine is running, the valve opens at certain times to allow a portion of exhaust gases to be routed back into the intake manifold. These exhaust gases displace some of the fresh air-fuel mixture, effectively diluting it and cooling the combustion process inside the cylinders. By lowering the combustion temperature, less NOx is produced, which is better for the environment and helps the vehicle remain compliant with emissions regulations.

Given its importance, the EGR valve requires attention during regular servicing to ensure it continues to perform well. Over time, since the EGR valve deals directly with exhaust gases, it can become clogged or stuck due to carbon build-up. This can lead to a number of issues including rough idling, poor fuel economy, increased emissions, and sometimes engine warning lights appearing on the dashboard.

For owners of a 2020 Mitsubishi ASX, maintaining the EGR valve involves a few key steps under the car's scheduled service inspections.

• Regular inspection: Your mechanic will check the EGR valve for any signs of sticking or carbon build-up during servicing intervals.
• Cleaning: If carbon build-up is detected, the valve and related EGR passages can often be cleaned using specialised tools and solvents to restore proper operation.
• Replacement: When cleaning is no longer sufficient, replacing the EGR valve with a genuine or high-quality aftermarket part is recommended to maintain engine performance and emission standards.

Ignoring EGR valve maintenance on the ASX can lead to a chain reaction of mechanical problems. A dirty or faulty EGR valve can cause the engine to run hotter, which in turn can trigger problems such as knocking, misfires, or even damage to the catalytic converter. This not only affects vehicle performance but could also land the owner with costly repair bills down the track.

Fortunately, replacing or maintaining the EGR valve is a relatively straightforward task for a qualified technician. The part itself is readily available for the 2020 Mitsubishi ASX, and specialists familiar with Mitsubishi vehicles will be able to service this component without hassle.

To keep the 2020 Mitsubishi ASX running cleanly and efficiently, following Mitsubishi's recommended service schedule is key. This not only ensures the EGR valve stays in tip-top condition but also keeps other crucial engine control systems functioning properly. Additionally, if the check engine light comes on and diagnostics point to the EGR system, it is best to have it looked at promptly to avoid further problems.

In day-to-day driving, the EGR valve largely does its job quietly in the background. Most drivers won't notice it working, but it plays a vital role in keeping emissions low and the vehicle compliant with environmental standards. By paying attention to the EGR valve during servicing, 2020 Mitsubishi ASX owners help guarantee their car runs smoothly and responsibly for years to come.
