If the answer is yes to any of the above questions then your diesel Particulate Filter is more than likely blocked. Enviro Exhaust has the answer for you!

We offer an environmentally friendly service for all vehicles including cars, vans, trucks and plant vehicles. We offer various services backed by our no quibble guarantee and a no charge if we cannot clean.

Our process utilises the state of the art and proven technology cleaning process, machinery purposely designed for the cleaning of DPF, DOC’s, SCR’s and Catalytic converters.

DIESEL PARTICULATE FILTER CLEANING PROCESS

On arrival the DPF is allocated a job number which is engraved onto the main body of the DPF. If the unit has been stripped down prior to delivery then both parts (DOC and the DPF) will have the same job number engraved on each unit.

A maintenance sheet is allocated to each job and the company and vehicle details are recorded on the sheet prior to work commencing.

A thorough visual inspection externally and internally with a bore-scope camera is undertaken. If any defects are found we will advise you immediately before proceeding.

The Flash Cleaner Machine will then perform a pre-clean flow test to gauge the level of soot content in the DPF.

The high pressure system then back flushes the DPF to remove the carbon and soot build-up followed by the drying cycle.

A post clean flow test is performed.

A DPF report is produced for the customer showing the before and after flow test results.

NOTE: The particulates that are cleaned from your DPF are captured & contained in a purpose built ultra-fine particulate filter trap within our machine. They are then disposed of at a council approved hazardous waste disposal site.
This ensures we are doing everything we can to minimise the impact on the environment.

Diesel Particulate Filters (DPFs for short) are devices fitted to diesel engine vehicles to reduce the sooty particles that diesel engines produce.

We have all seen the black smoke coming from the rear of Diesel vehicles and trucks polluting the atmosphere and the air we breathe. This can penetrate deep into the lungs and is seen as being responsible for an increase in heart and lung problems.

The diesel particulate filter(DPF) has a honeycombed interior, similar to a catalytic converter, which is made of Silicon Carbide. This is inside a stainless steel surround that you can see under the vehicle.

The honeycomb centre is designed to trap the particles of soot which have not been burned off or cleared by an additive.

Some DPFs use an additive which enables them to burn off the soot particles and some are fitted close to the engine which means that the exhaust gases are hot enough to burn off the carbon soot particles.

When the filter is full and no more soot particles can be trapped the DPF needs to undergo a regeneration process, which converts the soot into smaller particles like a powder.

This will be evident by the performance of the vehicle, loss of acceleration, sluggish performance and higher fuel usage.

There are two types of regeneration – aggressive and passive – within the vehicle.

With the injection of diesel or additive (urea) into the DPF, the exhaust ignites the diesel or additive and an explosion takes place. With the high heat from the explosion, this will in turn cause the soot to burn down into a powder and allow it be expel out of the DPF. As you can imagine this is very aggressive, and not all the soot will be removed, therefore it will be performed many times, damage to the DPF can and does occur.

Driving at speed of 100Km for 20 minutes at high revs is usually enough to start regeneration if the DPF is not too blocked, this is a passive regeneration.

Sometimes the DPF will not be given the chance to undergo either of these regeneration processes, and the filter will become too blocked for a regeneration to take place. At this point the vehicle will need to undergo some type of professional service.

The only solutions at this stage which will leave the vehicle in its proper state, is to replace the filter (usually $4,000 or more) or to use a professional cleaning service such as the Enviro Exhaust environmentally friendly cleaning service.
