Exhaust gas recirculation is a nitrogen oxide (NOx) emissions reduction system used commonly in diesel engines. The EGR system works by recirculating a portion of the exhaust gas off the engine back to the engines cylinders. Modern engines require an EGR system to reduce the amount of emission and meet government standards.

Problems with the EGR valve often include a leaking or clogged valve. The problem causes pollution on the environment, and the vehicle to run poorly. Diagnosing the problem is simple with the right expertise, and repairs are just as simple.

Common Symptoms of a Bad EGR Valve

When an EGR valve goes bad, there are several symptoms to expect. The list of symptoms does not always occur together, and some do not show up until there are already severe problems. Anyone driving a vehicle with an EGR system needs to know what to look for when the system goes bad.

Rough idling
Really bad gas mileage
Lack of power during acceleration
Loss of power during idling
Check engine light is on with a trouble code
Common EGR Valve Fault Codes

Vehicles with EGR systems often have diagnostic codes stored in the PCM memory. These codes display in the check engine light area on the dash, and alert drivers to an issue. The codes make diagnosing the problem easier to repair, and faster to catch.

Following are the Types of Car Exhaust Smoke:
1. Black Smoke
Black smoke indicates that the engine is burning too much fuel, a condition known as running rich. This can be caused by several factors that disrupt the air-fuel mixture. (EGR issues & can be even Turbo)

2. White Smoke
It usually means that coolant is being burned in the engine, which means that something is drastically wrong. The most common cause of this is a blown head gasket, which can quickly lead to an overheating engine. (It can be DPF issues)

3. Blue Smoke
Blue smoke is a clear sign that your engine is burning oil. The liquid can leak into the combustion chamber where it is burned along with fuel. You'll probably notice your car misfiring when you turn the keys in your ignition, or find your vehicle shakes more than usual when idle. (It can be injector issues too)

4. Grey Smoke
If the smoke from the exhaust pipe is either grey or bluish-tinged, it generally means that your engine is burning oil inside the combustion chamber. Burning oil could be due to many causes, from leaky valve seals to bad piston rings.

Maximising DPF Performance:
Tips to Avoid Problems

Diesel Particulate Filter (DPF) is a crucial component of the exhaust system, designed to capture and remove harmful particulate emissions from diesel engines. In the UK, the DPF has become mandatory for all diesel-powered vehicles since 2007, onwards and failure to comply with the regulations can result in hefty fines and vehicle confiscation.

However, many drivers still struggle with DPF problems, leading to costly repairs and engine failure. This article discusses how to avoid problems from a blocked diesel particulate filter.

How Does DPF Work?

Before we dive into how to avoid DPF problems, let’s first understand how this component works—the DPF filter traps and stores soot and other particulate matter produced by diesel engines.

Over time, the filter will become clogged with the accumulated soot, and the engine management system will initiate a regeneration process to burn off the trapped particulate matter. However, if the regeneration process is not completed successfully, the DPF can become blocked, which can cause many problems.

How to Avoid DPF Problems?

Unfortunately, DPF problems can occur, leading to expensive repairs and downtime. Fortunately, there are a few simple steps you can take to help avoid DPF problems in the first place:

Drive at Highway Speeds

One of the most effective ways to avoid DPF problems is to drive at highway speeds for an extended period. When driving on the motorway or dual carriageway, the vehicle’s engine will reach a higher temperature, which is necessary for the DPF to regenerate successfully.

If you only drive in the city or make short trips, the engine may not reach the required temperature for regeneration, leading to a blocked DPF.

Regularly Check the Oil Level

Low engine oil levels can cause DPF problems, as the engine management system may not initiate regeneration if the oil level is low. Therefore, it’s crucial to regularly check the oil level, especially if you’re driving long distances.

Use the Correct Engine Oil

Using the wrong type of engine oil can also cause DPF problems. The engine oil should meet the vehicle manufacturer’s specifications, and it’s essential to use low-ash oil designed for diesel engines equipped with DPFs. High-ash engine oil can produce more soot, which can clog the DPF.

Don’t Switch off the Engine during Regeneration

If the engine management system initiates regeneration, it’s essential to let the process complete. Switching off the engine during regeneration can cause the DPF to become blocked, as the soot will not be burned off completely. If you need to stop the vehicle during regeneration, it’s best to let the engine idle until the process is complete.

Monitor Warning Lights

Most modern diesel vehicles have a warning light that indicates when there’s a problem with the DPF. If the light comes on, addressing the issue immediately is crucial. Ignoring the warning light can lead to more severe problems, such as engine damage.

Use High-quality Diesel Fuel

Using low-quality diesel fuel can cause DPF problems, as the fuel may contain higher levels of sulphur and other contaminants that can produce more soot. Therefore, using high-quality diesel fuel that meets the vehicle manufacturer’s specifications is essential.

Regularly Service the Vehicle

Regular vehicle servicing is essential to maintain the DPF’s performance and prevent problems. During servicing, the mechanic will check the DPF’s condition and perform necessary maintenance, such as DPF cleaning or replacement.

Different Types of Car Smoke and What They Indicate You:

Have you ever paid attention to the color of smoke coming from the exhaust pipe of your car? While this might sound odd, the color of your exhaust can give you information on how your vehicle is running and whether it needs attention. Exhaust is sometimes an easy indicator of car health.

1. White smoke:

The presence of water in the combustion chamber will create a whitish exhaust. One common cause of this is a broken or blown head gasket, which allows engine coolant/water to seep into your pistons, creating a white smoke with a noticeable odor.

2. Blue smoke:

This typically occurs when some engine oil is getting burned off. Worn or damaged piston rings can allow oil to enter the combustion chamber, creating smoke with a bluish tinge. This problem may be visible at startup but could disappear as your engine warms up.

3. Black smoke:

Black exhaust smoke usually occurs when there is incomplete combustion of your fuel/air mixture. This could be related to problems with the quality of your gas, engine airflow problems, or issues with your spark plugs and/or ignition coils.

4. 3. Grey Smoke:

Grey smoke in cars typically occurs from too much oil, a cracked PCV valve, or a transmission fluid leak. Incomplete combustion can occasionally happen as a result of a defective or failed turbocharger. Transmission fluid may potentially be causing grey smoke to appear.

If you see any of these exhaust colors, your engine needs attention. Before you spend a lot going to a mechanic or having work done on your engine, browse our catalog and identify the products that can take care of your issue.
