EGR Valve on the 2016 Mitsubishi ASX: What You Need to Know

The 2016 Mitsubishi ASX, a popular compact SUV in Australia, features a range of efficient engine technologies designed to meet both performance and emissions standards. When it comes to the Exhaust Gas Recirculation valve, or EGR valve, this particular model does include an EGR valve as part of its engine management system, especially in diesel variants and some petrol engine versions depending on the market and specific trim. The EGR valve plays an important role in reducing emissions and improving engine efficiency, which makes it a crucial component for keeping the ASX running smoothly and environmentally friendly.

So, what does an EGR valve actually do? Basically, the EGR valve is responsible for recirculating a portion of the exhaust gases back into the engine's intake manifold. You might wonder why you would want to put exhaust gases back into the engine. Well, by doing this, the EGR system helps to lower the combustion temperature in the engine's cylinders which, in turn, reduces the formation of nitrogen oxides (NOx) - harmful pollutants that contribute to smog and air pollution.

Lowering combustion temperatures is important because NOx gases form at high temperatures inside the engine. The EGR valve opens and closes at specific times to allow controlled amounts of exhaust gas back into the air intake. This dilutes the incoming air/fuel mixture and reduces combustion peaks, meaning fewer emissions and a more environmentally responsible vehicle.

For the 2016 Mitsubishi ASX, which aims to meet Australian emissions regulations and international standards, the EGR valve helps the engine achieve cleaner emissions without compromising too much on fuel economy or performance. This balance is especially critical in diesel models, which generally produce higher levels of NOx emissions compared to petrol engines. The petrol versions of the ASX may also use an EGR system, though often with simpler setups since petrol engines tend to have lower NOx emissions.

While the EGR valve is beneficial, it does require some attention as part of routine maintenance. Over time, the valve and its related passages can accumulate deposits from the exhaust gases, which leads to build-up of carbon and other debris. This carbon build-up can cause the EGR valve to stick or become clogged, leading to engine performance issues such as rough idling, loss of power, poor fuel economy, and even triggering the check engine light.

Proper servicing of the EGR valve on a 2016 Mitsubishi ASX involves periodically checking for these carbon deposits and cleaning or replacing the valve as necessary. Most mechanics recommend inspecting the EGR valve and its associated pipes during regular services, particularly if the vehicle is showing symptoms like unusual engine behaviour or increased exhaust smoke.

Here are some useful tips and advice for maintaining the EGR valve on a 2016 Mitsubishi ASX:

• Regular inspection during scheduled servicing ensures early detection of carbon build-up.
• If the EGR valve is clogged, professional cleaning can restore its proper function and prevent the need for full replacement.
• Replacing the EGR valve is sometimes necessary if it becomes stuck open or closed and cleaning is ineffective.
• Use quality replacement parts designed for the ASX to maintain engine efficiency and emission compliance.
• Keep an eye on engine warning lights and unusual symptoms to catch EGR problems early.
• Driving habits can also impact EGR valve health, shorter trips with cold engine operation tend to exacerbate carbon build-up.

One thing to keep in mind is that DIY cleaning of the EGR valve can be tricky due to the valve's position and the risk of damaging sensitive engine components. It is usually best left to trained technicians who have the right tools and experience. The cost of replacement or cleaning varies depending on the dealer or workshop, but keeping up with maintenance can save you money by avoiding more significant repairs down the road.

Another point to consider is that some aftermarket modifications can affect how the EGR valve functions or is utilised. For example, some owners may choose to disable or delete the EGR system in an attempt to improve performance or reduce maintenance issues. However, this is generally not recommended, especially for vehicles that need to comply with emissions laws. Not only can this lead to increased pollution, it can also result in failed roadworthy inspections and potential legal issues.

In short, the EGR valve is a small but vital part of the 2016 Mitsubishi ASX's emission control system. Taking care of it through regular checks and maintenance supports the vehicle's longevity, performance, and environmental friendliness. For any ASX owner trying to keep their compact SUV running tip-top on Australian roads, paying attention to the EGR valve during servicing is a smart move that benefits both the driver and the environment.
