The important thing you have to know about DPF cleaning
“Turning off the DPF warning light！”
What is a DPF?
It is a particulate filter and helps to reduce the harmful particles which come from diesel exhaust. The filter essentially catches the harmful unburnt particles and when the engine gets hot enough it burns them off. The DPF is located within the exhaust system, generally near to the engine. The nearer it is to the engine, the hotter it gets, and the more effective it will be, where manufacturers have mounted them some way from the engine we hear of lots of problems with blocked DPF filters.
Why does the DPF need regenerating?
If you only do short journeys or keep the engine at low revs these particles will build up to the point that the DPF gets completely blocked. When this happens the engine will not run and you need to replace the DPF filter. Hopefully, prior to this, your car’s ECU will notice the build-up and warm you. The warning light comes on to show that you need to alter your driving style to clear the DPF filter URGENTLY and this should NOT BE IGNORED. The DPF may become too blocked to clear by driving, so don’t ignore the warning light. Act immediately or your only option will be to take the car to a garage for repair. There is a narrow window where a mechanic can clean the DPF by forcing a regeneration but after this narrow window, your only option is to fit a new filter into your car. Some cars fitted with DPFs have a separate tank for a fuel additive which allows the engine to burn off the carbon at a lower temperature
How to clear the DPF warning light by DPF cleaning？
Your car’s handbook will have a section on cleaning your DPF or entering a regeneration cycle so we suggest you consult this as each car is slightly different. Here is a generic guide though that should be effective on most engines. Warm up the engine to operating temperature, then drive it for 15 minutes at constant speed on a motorway. Aim to keep the revs above 2000rpm for this period. The heat generated will help clean the DPF filter and the car’s Regeneration cycle will usually kick in under these circumstances. Warning: If the engine is misfiring or in the limp home mode you should avoid high revs, build up the heat slowly and steadily and go for a longer run. Ideally, you should take the car to a mechanic if it is misfiring to avoid further damage or problems. DPF cleaning machine can help you clean DPF thoroughly, Kingkar DPF cleaning machine is in our opinion the most effective machine on the market.
How to avoid a blocked DPF？
Use good quality fuel. High Cetane fuel from major brands is laden with additives that help burn off the particles. Cheap fuel usually adds to the problem. Tests have shown that high-quality fuel burns cleaner and leaves less deposits in your engine. Avoid short journeys where the engine does not warm up fully and trips where the car is not able to maintain 2000rpm for 5 mins. Using a good quality machine to clean the DPF is also an important way to protect your DPF. Kingkar DPF cleaning machine, your best choice!
