Once you’ve figured out what the causes for DPF failure are, the problem is – how can you detect it? There are plenty of indicators that can be easily identified to indicate that your DPF has become blocked.
Here are a few:
WARNING LIGHT ON YOUR DASHBOARD
Today, diesel vehicles have multiple sensors that can measure the effectiveness of their engines. When they find issues with engine performance, they report them to the computer on your vehicle. That’s when the warning signs in orange on your dashboard flash.
Even though the sight of the dashboard of your car glowing like a Christmas tree not pleasant, it may assist you in identifying the cause of your DPF and fix them before they become more serious.
INCREASED FUEL CONSUMPTION AND REDUCED ENGINE POWER
An increase in the rate of the use of fuel is among the most obvious indicators that there is a DPF failure. The primary function of your diesel particulate filters is the removal of exhaust fumes from your vehicle’s engine while trapping soot particles. Thus, if the DPF is clogged the exhaust gasses are not able to exit the engine as swiftly as they ought to.
The buildup of exhaust gasses alters the overall performance of engines which makes it feel less powerful. When this happens, motorists typically push the gas to increase the vehicle’s power. But this method does not seem to work. The engine uses more energy to clear the gases that are released from the DPF and leaves less energy for acceleration.
THE ENGINE WON’T START
The build-up of exhaust gasses can stop the engine from getting started. The engine will continue to refuse to begin until the pressure has been lowered.
However, this does not have necessarily mean bad. It’s your vehicle’s way to stop harm to your engine as well as the diesel particulate air filter. What’s the next thing to do? Talk to a mechanic as soon as possible.
TURBOCHARGER PROBLEMS
A blocked DPF causes various turbocharger issues, such as gas or leaks of oil. That is, the gas which builds up within the engine is unable to go. This is why it begins spilling out from the turbocharger. This could further lead to leaks in oil and reduce overall turbocharger efficiency.
If you want to prevent this from happening to your engine you will have to find proper dpf parts that will suit your car perfectly.
DPF MAINTENANCE TIPS
To ensure the condition of your diesel particulate filter , and to extend its lifespan You must ensure it’s capable of regenerating itself after it’s saturated with soot. At present, there are two primary kinds of DPF regeneration – passive and active.
PASSIVE DPF REGENERATION
Passive regeneration happens when the engine reaches temperatures greater than 350 degC. The higher temperatures allow the DPF to expel the accumulation of soot that has accumulated when the car is not in use.
One of the most significant benefits from passive regeneration is the fact that this is a completely automated process. It’s barely noticeable to the driver. But DPF regeneration is passive. DPF regeneration can only be achieved after the engine has reached the temperature required, typically over longer distances and at higher speeds.
ACTIVE REGENERATION
If the levels of soot in the DPF exceed the limit in the range of 45 percent, sensors that measure pressure register this. This is when the engine management system initiates the injection of raw fuel to the diesel oxide catalyst (DOC). This increases the temperature of exhaust, and also ensures optimal conditions for active regeneration.
Similar to passive regeneration, Active regeneration, too, is an automated procedure. It is not dependent on the driver. Similar to its passive counterpart the active generation process is possible when the car is driven for longer periods of time and at greater speeds.
