EGR Valve on the 2019 Mitsubishi Eclipse Cross: What You Need to Know

The 2019 Mitsubishi Eclipse Cross is a compact SUV known for blending style and performance, but when it comes to certain engine components like the EGR valve, it's important to understand if this part plays a role in the vehicle's operation. After checking technical sources and manufacturer information, it turns out the 2019 Mitsubishi Eclipse Cross does not use an EGR valve, at least not in the version fitted with the common 1.5-litre turbocharged petrol engine.

The Exhaust Gas Recirculation (EGR) valve is a device found in many petrol and diesel engines aimed at reducing nitrogen oxide (NOx) emissions. It works by recirculating a portion of the engine's exhaust gases back into the intake manifold. This lowers the combustion temperature and reduces the production of harmful emissions. Many vehicles, especially older models or those with larger, less advanced engines, have an EGR valve as part of their emissions control system.

However, the 2019 Mitsubishi Eclipse Cross, particularly the widely available 1.5-litre turbo petrol variant, utilises more modern emissions technology that negates the need for a traditional EGR valve. Mitsubishi has equipped the Eclipse Cross with more advanced engine management systems, including precise fuel injection and turbocharging, which help keep emissions low without relying on EGR. Additionally, Australian and global emissions standards pushed manufacturers towards improved catalytic converters, direct injection systems, and other methods to achieve clean combustion. This helps explain why an EGR valve is not part of the Eclipse Cross's engine setup.

There are a few reasons why Mitsubishi may have chosen to omit the EGR valve in this model:

• Modern direct-injection turbocharged engines already run efficiently with lower combustion temperatures, reducing the need for EGR to cut NOx emissions.
• The complexity and maintenance issues sometimes associated with EGR valves - such as clogging and valve failure due to carbon buildup - are avoided, improving reliability.
• Other emission control strategies like upgraded catalytic converters help the vehicle meet emission requirements effectively without an EGR system.

So for Mitsubishi Eclipse Cross owners in Australia, you will not find an EGR valve under the bonnet, and there's no need to inspect or service one. That means no worries about EGR valve cleaning, clogging, or replacement as part of your regular car servicing routine. Instead, focus on the other components, including air and fuel filters, spark plugs, and the turbocharger system, which have a more direct impact on your vehicle's performance, fuel economy, and emissions control.

But for those curious about EGR valves in general or who might be dealing with a different vehicle equipped with one, here's a quick rundown on what the purpose of an EGR valve is and some handy advice on its maintenance and replacement.

The EGR valve's job is fairly simple but important. By recycling a slice of the exhaust gases back into the engine's intake, it lowers the temperature at which the fuel-air mixture burns. Cooler combustion means less nitrogen oxide is formed - NOx being a major pollutant contributing to smog and health problems. Cars with EGR valves usually have them in the intake manifold or near the throttle body, controlled by the engine management computer which adjusts how much exhaust gas is recirculated depending on things like engine speed and load.

Over time, the EGR valve can get gunked up with carbon deposits. This buildup can cause the valve to stick open or closed, resulting in rough idle, poor performance, increased emissions, or the dreaded check engine light. That's why regular maintenance can be crucial on vehicles fitted with EGR valves. Cleaning the valve and the passages with a specialised cleaner can often solve minor issues.

If the valve is faulty or too clogged to clean properly, replacement is usually the best option. New EGR valves aren't too expensive and swapping one out is a relatively straightforward job for a mechanic or a confident DIYer. Keeping the EGR functioning well helps maintain engine efficiency and keeps emissions within legal limits.

Servicing the EGR valve on vehicles that have one should be part of routine maintenance schedules, along with other emission-related systems like oxygen sensors and catalytic converters. Doing so helps the car run smoothly and can prevent expensive repairs down the track.

To sum it up, if you're driving a 2019 Mitsubishi Eclipse Cross, you do not need to worry about an EGR valve because this vehicle does not use one. The decision by Mitsubishi to exclude the EGR valve is based on using newer engine and emissions technology that keeps the car cleaner without this extra component. So instead of EGR valve checks or replacements, keep an eye on the usual service items recommended in your Eclipse Cross maintenance schedule, and your car should stay in great shape for years to come.
