Diesel Particulate Filters (DPFs) are part of a diesel vehicles exhaust system. DPF cleaning should be carried out as a regular service. The benefits of DPF cleaning are improved fuel efficiency, reduced emissions, and extended lifespan of your engine and components.
One of the most critical issues is the increased risk of engine damage leading to higher maintenance costs and truck repairs. Without the DPF filter in place, diesel engines accumulated soot and other particulates can build up on engine components and cause excessive wear to trucks.
Aside from increasing your risk of being charged with motoring law violations, removing your DPF and EGR can improve your car's power, performance, and fuel efficiency.
Perhaps the most critical disadvantage of removing DPF is the increase in soot and particulate matter volume in the air. Besides, you will be more likely to be fined for removing DPF based on the regulations that governments pass for climate control.
A diesel particulate filter on a poorly serviced car may fail sooner than a well maintained one, generally, they should last for at least 100,000 kilometres.
Generally, it's recommended that a DPF be cleaned roughly every 150,000-200,000 miles. At this point, ash in the filter cells begins to harden. This hardening can cause the filter to crack, resulting in permanent damage.
A maintained DPF is capable of 200,000 + kms before removal for correct cleaning or replacement.
DPF BENEFITS
Better fuel economy: Fuel economy is a big winner after deleting the DPF. Not only will a vehicle conserve the fuel that is utilized by the filter for regenerative purposes, but a cleaner running engine is also an engine that runs more efficiently.
In many cases, a proper DPF delete will result in gaining over 100 horsepower while improving your fuel mileage and the lifetime of your vehicle.
"Maximum court-imposed penalty for an individual is $22,000!" Is a DPF delete legal? Okay, so the $22,000 question: is it legal, and can you get fined for deleting the DPF? The short answer is, yes you can get fined, and no, it's not legal.
REDUCE IDLING
Even at low engine speeds particulates are emitted by your engine, so keeping your engine ticking over when you're parked or not moving can clog your filter quicker, because DPF regeneration cannot occur at idle.
So it is advised that drivers regularly give their diesel vehicle a good 30 to 50 minute run at sustained speed on a motorway or A-road to help clear the filter.
Blocked DPFs wreak havoc with the delicate balance of your engine by preventing the normal venting of gases, which causes a variety of engine issues, as described above. In addition to reduced power and fuel efficiency, a blocked filter may eventually cause a dangerous mechanical malfunction and break your engine.
DPF, especially when clogged, affects airflow and causes delays in the exhaust process. Additionally, it affects the overall engine performance and power. When you remove the DPF, fuel flows better into the engine, boosting power generation and pressure. DPF delete is a sure way to increase engine horsepower.
One final consideration, it takes time for a DPF to block, sometimes years. Once blocked though, turbo failure can occur very quickly.
The easiest and cheapest method of DPF filter cleaning is by driving the vehicle for a long-distance at high revs per minute. Doing this increases the heat of the exhaust and burns the soot blocking the DPF filter. It's best to drive on a motorway or A road where you can keep the vehicle at a consistent speed.
You should consult the handbook for your vehicle for more specific guidance on how you should drive to initiate regeneration of the DPF and clear the warning light. Nevertheless, a general rule of thumb to follow is that you should run the engine at least 40 mph and at least 2500 rpm.
No, it's illegal to remove or delete your EGR. Your vehicle has been designed by the manufacturer to operate with an EGR system. It is illegal and will also void the manufacturer's warranty on your vehicle and Australian consumer law protections.
In most cases, the automated software won't delete these parts of the file, but then leaving part of the DPF file in place will also bring problems such as the vehicle falling back into limp mode, the DPF light coming back on, excessive smoke and as a result of this, an MOT Failure.
No. If a vehicle is in good mechanical condition and has been well maintained then removing the DPF will not result in a smoke test failure. However, a mechanical engine issue which results in the engine running too rich and producing excessive smoke could lead to a failure.
How Often Does DPF Regeneration Occur? Active regeneration happens roughly every 300 miles and is triggered by your car's electronic control unit (ECU) once your soot level is approaching 40 to 45%. Passive regeneration should occur when you take your car on longer journeys at higher speeds.
For on-highway vehicles, the DPF should be pulled off for its first cleaning after 150,000 to 200,000 miles, and then every 100,000 miles after that for preventive maintenance cleaning, Anderson notes.
Alter your driving habits
Do your research and find out how many miles you need to drive, and at what speed, to initiate the regeneration process and allow it sufficient time to complete. This will prevent any build-up of soot and particulates in the filter and extends the life-expectancy of your DPF.
When mild service is necessary, the Bluechem DPF Top Gun Cleaner combined with the High Pressure Gun allows automotive service shop to clean the DPF without removing it from the vehicle. For High build-up of soot and residuals (Clogged DPF), severe service of the DPF flushing is the solution.
