FAQs about Engine and Durga H2-Clean

Here are some frequently asked questions:



H2-Clean is a French owned brand name associated principally with a suite of equipment, utilised for decarbonising Internal Combustion engines – of all kinds. Here in the Nepal the services are available via a network over Approved centre like Durga Engineering & Auto Works Pvt. Ltd.

The most commonly recognised service is the preventative maintenance process which removes carbon and other lacquers which build up within your engine, thus restoring vehicle efficiency, improving MPG, reducing harmful emissions and prolonging the life of certain components.

Other services include unblocking of Exhaust Gas Recirculation system – EGR and Diesel Particulate Filters – DPF components on diesel vehicles.

The first and most important factor is that all Authorised Durga H2-Clean Service engineers have been trained by H2-Clean. This ranges from the standard initial training to use the equipment, but progresses through to high level diagnostic training to ensure they have a good understanding of why DPF blockages occur. We train technicians to understand how to unblock the unit and far more importantly to identify the cause of the blockage and how to resolve that problem so blockage does not simply re-occur.

Durga H2-Clean technicians utilise their knowledge to identify the best solution from the portfolio available to provide service to your vehicle, in consultation with yourself. Many of our Durga H2-Clean service centre and mobile technicians offer full vehicle service facilities so this can be done when you are having the car given its routine service. Many may already be known to you as they have been servicing vehicles for many years and simply added Durga H2-Clean with a limited range of other services and some are 100% Durga H2-Clean. All of our technicians are experienced knowledgeable vehicle technicians. The equipment is not for sale to enthusiastic amateurs.

We do not own any of the service network. They are all independent businesses which have bought the equipment from ourselves, been trained by ourselves and are provided with the authorised consumables and technical support by ourselves.

Yes.

Durga H2-Clean is a unique system for cleaning. It is not just about the chemistry, Durga H2-Clean uses French technology product to clean from injectors – through the combustion process and cleans post combustion too. Thus cleaning through EGR and DPF.

Good pour in products are very capable of cleaning intake and injectors but not post combustion. This also applies to other equipment based cleaners on the market place, which claim to clean the entire system they do not employ our unique H2-Clean technology, they are principally only cleaning intake and injection not full system and all-important post combustion components including key sensors are not cleaned at all.

During a standard Durga H2-Clean decarbonization service the equipment is attached to the vehicle and takes over as coupled with the technology of the equipment.

We set Recommended Retail Prices (RRP) for a standard preventative maintenance service, which are:

Vehicles that use 1hour of cleaning at RS.2500.00
Vehicles above 2hour from RS.4000.00

Larger vehicles including trucks and buses may cost significantly more.

Note: whilst we set RRP. we are not legally permitted to enforce price levels for the dealers so please do confirm the cost price at the time of booking.

Services such decarbonization are priced by each Authorised Service centre based upon their own labour rates.

Yes, we do almost all vehicles. From a Motorcycle, Car, Van, HGV, Bus, Agricultural engines. There are a few exceptions which we can not do, but our local service centre/engineer will confirm when you arrange to book your vehicle in. We have now Durga H2-Clean (Jan 2019) over 100 vehicles including, motorcycles, cars, vans, trucks, buses, (outboard & inboard engines), mini generators, and gen-sets, plant & machinery; excavators

We already have excellent Nepal coverage, but continue to develop the network to ensure we can provide a consistently high level of service across the Nepal. At the top and bottom of every page you will find the “CONTACT NUMBER”, simply give us a call.

No. H2-Clean and Durga Engineering & Auto Works Pvt. Ltd. are two seprate entities.

Yes. Most cars operating on LPG ran as petrol vehicles before conversion, and build up carbon deposits during that period. Durga H2-Clean will remove those deposits. LPG does not create much carbon so a further service is not usually required.

Yes. Hybrid technology and vehicles which use Stop-Go systems to save fuel are inherently prone to carbon build up and will generally develop more carbon deposits than other vehicles with similar mileage.

As a general rule we say a car is due a Decarbonization after about 15,000 KMs. But if most mileage is done about town the service may be better done at a lower mileage, if most mileage is done at motorway speeds then less carbon will have built up and the service will be due at a slightly higher mileage.

Read the above answer in conjunction. We generally say you should have your vehicle Decarbonized every 15,000 KMs.

We are the brand importers, manage the network and set Recommended Retail Prices. Give us a call for better uderstanding and service.

Whilst a Durga H2-Clean service is only due periodically there are things owners can do to reduce the amount of carbon which builds up. We recommend using a good quality branded fuel, cheaper fuels have a higher volume of additives and bio-fuel which increase both carbon build up and the amount of tars, gums and resins deposited.

We do also have some products which can be used between Durga H2-Clean services and will help keep the vehicle operating efficiently.

The simple answer is “no”. A Durga H2-Clean service is using a high level technology equipment which can cause no harm to your vehicle or any of its components. A Durga H2-Clean service will remove carbon which has built up over time from your vehicle, as well as other contaminents (tars & lacquers) which build up and deteriorate the performance of your vehicle.

Durga H2-Clean is not a “fix” for a problem, it is a highly effective preventative maintenance service which will help prevent problems occuring, prolong component life and improve the efficiency of your vehicle in terms of performance, fuel economy and emissions.

A standard Durga H2-Clean will clean through EGR & DPF systems if there is adequate air-flow. BUT a standard Durga H2-Clean is a preventative maintenance service, most of our service centre also own specific Durga H2-Clean tools for cleaning EGR & DPF and these can be used to unblock most units.

If the unit is blocked with ASH, which no on-vehicle service can remove, Durga H2-Clean service centres have access to a return to base service which will remove ash from the unit. What we recommend is that you always have a chat with your local Durga H2-Clean centre if you are being advised to replace your DPF unit, they are expensive and we consider that most are replaced when they can be cleaned.

This is due to lack of knowledge and training. We make excellent technical training available to Durga H2-Clean technicians. We also recommend that you do not have a DPF removed permanently they are there for a reason and without the DPF your vehicle is emitting harmful particles into highly populated areas.

Simply talk to the agent when booking the car in about your requirements.
