WELCOME

Here at // J G CARBON CLEAN our sole purpose is to make sure that your vehicle is running as cleanly and efficiently as possible.

Is your DPF blocked putting your vehicle into limp mode with warning lights displayed on the dash...???

Are you experiencing.......

- loss of power...???

- loss of performance...???

- poor starting...???

- smokey acceleration...???

- poor fuel efficiency...???

Has your car or van failed its MOT emissions test or are you worried because you have your MOT test coming up...???

Do you know the service history of your car or van???

Have you been told by your garage or mechanic that you need to replace expensive engine components because they are clogged up...???

All of these problems can be attributed to a build up of carbon and soot deposits within your engine and DPF which can be incredibly costly if left untouched. The ideal way around this is prevention with regular carbon cleans but in the majority of cases the vehicle is already suffering which is where we can help.

ABOUT....

With over 30 years experience I've come across just about every engine carbon buildup problem imaginable with both petrol and diesel engines on cars and vans.
I removed my first engine at 11 years old which was a 3.5lt rover V8 (for those of you old enough to remember those cars). I've had various car projects with my dad throughout my school years, passed my driving test and purchased my first car at 18. From that moment on my involvement with cars and vans has been constant.
It's true that older cars and engines built 20+ years ago were much easier to work on and diagnose problems but they were just not built to last, whereas newer cars and engines built within the last 20 years under stricter rules and regulations have been built to a much higher standard and generally last much longer.
However these stricter rules and regulations bring with them their own set of engine problems with the mandatory use of exhaust gas recirculation (EGR) valves and diesel particulate filters (DPF).

EXHAUST GAS RECIRCULATION (EGR) VALVE.

The logic behind these components is great. The EGR valve will recycle exhaust gases and allows for the gases that are produced by the engine to be sent through the system for a second time so it can go through extra combustion. By warming up the gas one more time the amount of nitrogen oxides will be decreased. It does this by sending it back through the air intake system which is fantastic for the environment but over time turns into a horrific problem for the car/van owner.
As the whole combustion process takes place it creates carbon deposits which slowly but surely latch on to anything and everything they can such as throttle bodies, turbo veins, intake manifolds, air pipes, EGR valves, injector tips, spark plug tips, inlet valves, catalytic converters, diesel particulate filters (DPF) etc.
As time goes on and with more and more use of the engine the carbon deposits build up to a point where they seriously start to restrict air flow, the combustion process and the correct operation of crucial components.
This is not healthy for any engine. For an engine to work efficiently and as you would expect then a clear air flow and clean combustion is essential in all aspects of operation and performance.
Without a clear air and gas flow the engine is unable to breathe and the struggle begins. If you think of it in human terms, when you have a cold your nose gets blocked, your chest fills up, breathing becomes difficult, you feel terrible and you are unable to perform properly. Well, it's much the same as an engine, the only difference is your engine doesn't get better on its own, it just gets worse putting more and more strain on the engine itself and the components until it can't carry on anymore.

DIESEL PARTICULATE FILTER (DPF)

As with the EGR valve the DPF was designed to help keep exhaust emissions down to a minimum and was made a mandatory component for diesel engines in 2009.
The DPF is one of the most critical aftertreatment devices on your vehicle. It catches and stores exhaust ash particles and other contaminants to reduce particulate matter (PM) from diesel engines.
Cellular ceramic honeycomb filters are the most commonly used on most cars. This DPF consists of channels that are blocked at each end forcing the gas containing soot particles through the filter wall. Whilst the gas can go through the filter the dangerous soot remains trapped in its pores.
The DPF has a limited capacity, therefore the soot trapped needs to be removed to enable proper performance of the filter. This process is called DPF regeneration.
During regeneration excess soot in the filter is burned off. This normally happens whilst the car is in use and the driver will not even notice when this process is happening.
HOWEVER, in much the same way as the EGR valve and other engine components can clog with deposits, so can the DPF. As time goes on the filter can get clogged with soot & ash and the regeneration will release less and less until it eventually blocks up and is unable to be cleared on its own.
This is a very common issue for diesel cars/vans that only carry out short cold engine journeys.

How does carbon deposit buildup form...???

Carbon deposits and buildup are a byproduct of combustion that comes from incomplete fuel combustion. This black soot, similar that which collects in a chimney, will harden on internal engine components such as injector tips, spark plug tips, turbo veins, inlet valves, cylinder walls, exhaust gas recirculation (EGR) valves, diesel particulate filters (DPF), catalytic converters, air inlet system etc, regardless of whether it's a petrol or diesel engine.
It's basically unburned fuel that evaporates and sticks to the engines internals as carbon deposits. These deposits impede the flow of air and fuel and lead to a loss of performance and a much higher fuel consumption.

Reasons for carbon and soot buildup...

Low quality fuels...
Fuel is not nearly as good quality as it used to be years ago. Modern fuel is much more contaminated and full of additives that seem to do more harm than good when it comes to the perfect combustion and it's the engine that pays the price.

Short journeys...
This is a big one. Drivers who are only using their cars/vans for short journeys are experiencing many more problems with carbon deposit buildup. This is due to the fact that a cold engine will always be less optimal for complete combustion. On shorter journeys your engine doesn't get a chance to warm up which leads to more and more carbon buildup and the DPF clogging up.

Start/stop travel...
Start/stop travel is a nightmare for your engine. I think most of us can say we've been stuck in many traffic jams over the years. This means more engine load leading to more excessive carbon buildup. With day after day of traffic congestion the diesel particulate filter (DPF) doesn't get a chance to regenerate once again leading to more carbon buildup and soot.

Lack of servicing and maintenance...
Service plans are there for a reason, to ensure that potential issues with a vehicle are spotted early enough and also to keep the vehicle maintained and in a road worthy condition. Having your engine oil and filter changed at regular intervals is crucial for a healthy engine. Along with this the air filter and fuel filter are just as important and often overlooked. A clean fuel filter keeps the fuel flowing nicely and a clean air filter introduces the cleanest air possible into the intake system. If either of these are dirty, partially blocked or fully blocked it will throw the mixture out causing more carbon deposit buildup.

No carbon clean service plan...
We've all at some stage heard ''your EGR valve is blocked'' or ''your turbo needs to be replaced'' or ''your DPF is blocked'' or you've experienced an engine warning light on your dash and possibly even the car going into limp home mode. Of course there are other mechanical issues that can cause these problems BUT with a regular carbon clean (every 6 months to 1 year) these problems can really be pushed back to a minimum.

Symptoms of excessive carbon buildup and blocked DPF.

Weakened engine performance...
A sluggish feeling to driving. Decreased acceleration and less power in all gears.

Rough idling...
With a disrupted fuel injection and air flow your engine will not run as it should. It can judder on idle causing vibrations and is often louder than before.

Black smoke...
Black or dark smoke from the exhaust is one of the most obvious visual signs of carbon build up. Most of us have experienced unwanted smoke either from our own cars/vans or the person in front of us that suddenly accelerates hard. It's easily spotted at night coming from your own vehicle when you accelerate and see smoke in the headlights of the car behind you whilst looking in the rear view mirror.

Unpleasant smells from the exhaust...
A rich exhaust smell. Sometimes a smell of burning and often a smell on petrol cars described as fishy. This is normally the catalytic converter.

Bad fuel consumption...
Using more fuel than you used to is another sure sign of carbon build up. With a carbon clean you can notice a 10-15% improvement in fuel efficiency.

Failed emissions test for the MOT...
With MOT emission tests becoming ever tighter it's getting harder and harder to pass the test. This one is another big problem for many.

Unfamiliar engine noises...
Knocking, pinging or ticking sounds from the engine can indicate high levels of carbon buildup.

Dash warning lights...
The engine warning light, coil light and emissions lights are often associated with problems caused by carbon build up.

Misfires...
Sometimes misfires are extreme but sometimes they can be very light and not really noticeable to the untrained ear. Either way even the slightest misfire can turn into a huge problem.

Turbo lag...
Have you noticed that your turbo is not boosting as well as it used to? This is very likely to be caused by a buildup of carbon deposits beginning to block the turbo veins. These veins are extremely thin and it's vital for them to be kept clear for the turbo to operate correctly.

Limp home mode...
Have you experienced your car/van going into limp mode? In some cases you can turn the engine off, start it again and it's back to normal until the next time but in other cases once it's in limp mode it stays that way until it's been diagnosed with a computer and once again sooooooo very often it's linked to a buildup of carbon.

Harder starting....
Difficult starts are another sign. Normally more prominent when the engine is cold but this does still happen when the engine is warm.

All of the above symptoms of a rough running, under performing engine can be seriously attributed to a buildup of carbon and soot deposits within the engine and DPF. It is so very often overlooked as being the cause of these problems and it's all too easy for mechanics and garages to say ''you need a new EGR valve or ''turbo'' or ''DPF'' at a massive expense to the car/van owner when in reality a huge majority of these components are still operational and can be brought back to working life with an engine carbon clean or/and DPF clean.
Of course some of these problems can still be caused by other mechanical failures. As amazing as a engine or DPF clean is it will not fix components or sensors that are actually broken.
If you have a broken component then this will need to be replaced.
However in 95% of the cases I've dealt with an engine carbon clean or/and DPF clean has completely rectified these problems with fantastic results leaving the engine with smoother running, better starting, greater MPG & BHP, much better general all round performance and bringing the love of driving back to the car/van owner.

The benefits of a hydrogen carbon clean or/and chemical DPF clean.

The benefits you can expect are incredibly good and very effective for the engine.

* Improved MPG (10-15%).

*Restored lost power (4-11 BHP).

*Improved throttle response.

*A much cleaner turbo and lower turbo lag.

*Reduced engine knocking, noise and vibrations.

*Improved engine idling.

*Reduced or no black smoke.

*Lowered emissions up to 70%.

*Cleaner injectors.

*Cleaner valves.

*Restored performance.

*A prolonged engine life with a considerable amount of less wear and tear on engine components.

*Huge Savings on future repair bills.

*Really helps to prevent very costly EGR, turbo, DPF and catalytic converter problems.

How the engine carbon clean process works...

For maximum performance , fuel efficiency and smoother running for your vehicle it's vitally important to keep your engine's internals clean and free from carbon deposit buildup.
Our machines use a mix of KOH crystals and distilled water to create hydrogen gas which then gets pumped through a small tube into the engine via the air intake whilst the engine is running.
Hydrogen burns at a very high rate whilst in the engine and as the gas passes through the induction system, combustion chamber, exhaust etc the hydrogen reacts with the carbon deposits and simply burns, loosens and chips away at it. This lifts the carbon deposits from the engine and the resulting gas exits via the exhaust system.

The areas reached with a carbon clean are.........
* Catalytic converter.
* Exhaust gas recirculation valve (EGR).
* Valves.
* Turbo.
* Injector tips.
* spark plug tips.
* Glow plug tips.
* Full combustion chamber.
* Exhaust.
* Areas of the intake system and throttle body depending on their locations within the engine.

The hydrogen gas focuses mainly on the areas of carbon buildup where the engine is naturally hot such as the combustion chamber, the turbo, injector tips, valves, piston heads, EGR valve, the catalytic converter and can have fantastic results.
It also reaches the areas where there is less natural engine heat such as inlet manifolds, throttle bodies and the air intake system. The effectiveness on these areas can vary from engine to engine depending on the layout of these components within the engine bay. However even on the these areas with less heat it does still help to reduce the carbon buildup deposits.
It is not corrosive to the engine itself or its components. There are no engine side effects afterwards and no engine components need to be removed from the car. In fact the only manual work that needs to be carried out from us is to loosen the air intake pipe so that the hydrogen pump tap can be positioned for maximum effect.

How the DPF cleaning works...
This is carried out by injecting a chemical cleaning agent directly into the DPF via either the exhaust temperature sensor, the o2 sensor or most commonly through the differential pressure sensor hose.

The injected chemicals enter the DPF in liquid form and then quickly expands into a foam that simply breaks down the carbon, soot & ash. After a short waiting period where the chemicals are left to work their magic the unwanted contents of the DPF are then forced out of the exhaust system under the natural pressures of the engine running at various RPM leaving the DPF clean, the pressures back down to where they should be and the vehicle back to normal operation.
