Ash" is metal oxide formed by the normal combustion of metal atoms that are common components of engine lubricating oils. Ash from phosphorus and sulphur can be expected from most lubricating oils. Ashes are troublesome to the engine as they are solids that condense on the diesel particulate filters, see Figure 1. "Soot" (also known as "particulate matter" or "particulate"), is large molecular weight polyaromatic hydrocarbon formed by the incomplete combustion of fuel. Soot also condenses on the diesel particulate filter; this is the purpose of the filter. However, the effectiveness of the filter can be lessened due to the combination of soot and ash. If the fuel and air can be properly mixed, the "prompt" NOx formation will not take place. This will lead to a cleaner operating engine. The benefits of this to the owner would be; non-failure of vehicle emissions tests, prevention of maintenance of engine-catalytic converter, in principal the redundancy of the exhaust gas after treatment system. Therefore, it is logical to suggest that the ability of Dipetane to enhance the mixing of fuel with air should provide a reduction in NOx production and therefore a reduction in the effort required to clean the exhaust gas. Review of "Dipetane in Engines" The use of Dipetane in a gas-oil fueled burner is studied. The boiler thermal efficiency was monitored in accordance with BS7190. Oxygen, carbon monoxide, sulphur dioxide, nitrogen monoxide and nitrogen dioxide are also measured. The thermal energy generated due to the boiler operation is also measured. Theory If you google it, then pretty sure it will show up as a paid ad on your Facebook feed, worth a read of all the comments of advocates of additives, include loons who add veg oil on every fill up for its cleaning properties. What's more, independent tests by consumer group Which? have revealed that these supplements don't tend to deliver on their promises of adding oomph to your engine - some can even increase the cost of a petrol refill by 50 per cent! Most of these products claim to increase a fuel’s octane rating (a higher number can make the engine run smoother), but none managed even to equal the rating of premium-grade petrol. Alternatives
This is to an extent consistent with an observed appreciable increase in carbon monoxide concentration after Dipetane addition; I would expect a much larger increase in carbon dioxide concentration. However, carbon dioxide measurements were not attempted. Conclusions So, what’s the bottom line? Using Dipetane on a consistent basis will save you money in costly repairs, provide better fuel economy and help produce a cleaner environment through less toxic emissions.This is where cleaning of the DPF comes in. However, it’s not like any other filter that can be removed and replaced. Your vehicle’s Engine Management System handles cleaning the DPF. This occurs automatically once the vehicle to reach and maintain an engine load high enough for to heat the exhaust to a point where the soot particulates can be vaporised or converted into O2 and safely released from the exhaust system. The build-up of matter or soot is unavoidable with diesel engines, especially if the vehicle is driven that way that prevents the DPF from clearing, such as regular stop start driving. But how can the DPF be better managed to reduce the risk of clogging up? Dipetane is a fuel technology that enhances the combustion process by burning more carbon and cleaning the engine internals and then assisting the DPF in its regeneration process, all without the need for additives. This results in more fuel efficiency, minimal carbon deposits and lowers exhaust emissions. The evidence provided by these technical documents is summarised below. The validity of the evidence with regard to the state-of-art in fuels, combustion and emission science, in the opinion of the author, is also stated. With the information of these supporting technical documents, a summary briefing note on Dipetane dated April 2017, "Dipetane Technical Summary", is also examined. Dipetane claims to allow the fuel to be burned more completely by enhancing the interaction of the fuel with oxygen contained in the air. The arguments presented pertaining to the problem to be solved by Dipetane are certainly very consistent with the scientific consensus in the international combustion research community. So I happened to be going for a long drive and on the return the engine light came on and the car began running very poor. The Idle is very rough, there is poor and rough acceleration and (i think) increased fuel consumption. If there’s an issue with your DPF the cost can be astronomical. Protecting your DPF through the use of Dipetane is the best way to prevent DPF damage or build up. Dipetane treated fuel has a unique ability to burn carbon more completely compared to all standard fuels meaning that much less unburnt carbon enters the DPF and therefore the regeneration occurs less often. As an example, in some 6.8-litre engines Dipetane’s use has extended the regeneration from 70 hours out to over 200 hours. This is a substantial fuel saving and protects the DPF from the very high temperatures involved in the regeneration process.
Simply fill up your vehicle with an amount of litres of fuel and then pour in the corresponding amount of Dipetane, e.g. for 40 litres of fuel pour in 4 units of Dipetane.Delivery Days: All delivery days are classed as Monday to Friday. Next day from Friday is Monday Delivery. All delivery times are what we strive for but are approximate, as delays can happen due to circimstances beyond our control. The study specifically investigates this question for Dipetane fuel treatment, but concludes no reductions in NOx due to the addition of Dipetane. However, the study does note a reduction in both CO and particulate matter, as noted in the other studies documenting the use of Dipetane with regular, petro-diesel. This is again consistent with a theory of Dipetane effecting an enhanced mixing of fuel with air. NCT Test Results, Ireland Dipetane burns the carbons that would normally cause carbon deposit build-up, therefore extending both your oil and engine life. Proven in over 100 million miles of service, Dipetane improves fuel economy, reduces emissions, extends oil life and reduces engine wear.
- Cut your fuel bills by 10%
- Cut pollution by 25%
- Lower smoke by 50%
- Reduce your maintenance costs
- Proven performance in Europe, USA, Australia, Korea, and China.[/list]At the heart of Dipetane's ability to increase fuel economy 10% to 15% is its more efficient and complete fuel burn. The result is increased energy release and a longer, more powerful expansion in the combustion chamber.
My mechanic told me to fill the tank again - it was 2/3 empty - and drive it around for a few days so that the Dipetane will be diluted and it's effects gone from the exhaust before going for a re-test. Therefore, in addition to the well documented involvement of combustion deposits in limiting engine lifetime, they also retard the ability of the engine to convert the chemical energy of the fuel into useable power. The review finds several pieces of literature that demonstrate that the occurrence of combustion chamber deposits inhibit complete combustion, thus contributing to a cascading degradation in engine performance. The report does not mention Dipetane in any specific way. In the morning I hop in the car and before I do anything else I start the engine after a double glow plug warm. When the engine starts I don't rev it but let it idle for a few moments to flush as much water out as possible. Now wig an older citroen this can take a minute as I let it fully settle the suspension and put my seat belt on, plug my phone into the radio and get ready to go. Generally, diesel engines operate well with a CN from 48 to 50. Fuels with lower cetane number have longer ignition delays, requiring more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher cetane number fuels."Hi I just added Dipetane to my petrol as I have a NCT due, I do a fair bit of city driving in traffic so wanted to give it a bit of a clean out. These systems are typically as expensive and as heavy as the engine itself. This obviously adds to the production and fuel operating costs of the vehicle. Urea is used in these devices to remove oxides of nitrogen formed by the poor combustion of the fuel. NO and NO2 (NOR) are harmful pollutants and legislated to be produced at no more than 60-280 mg/km from 2009 (Euro V) [4] and 60-125 mg/km from 2013 (Euro VI) [5]. The catalytic converter removes the NOR by reacting it with ammonia, NH3. Ammonia is produced on-board the vehicle from urea, NH2CONH2. The more NOR that is produced by the engine, the more difficult it is for the catalytic converter to remove all of the NOR. To evaluate the claims made by Dipetane with regard to passing emissions tests and reduction of NOR, it is necessary to understand this basic science of the exhaust gas after treatment system, but also the basic science of NOR formation. In a basic way, there are two methods by which NO and NO2 can form. The first, commonly known as "Thermal NOR", is by the thermal decomposition of the nitrogen (N2) contained in the air.
Before I added this stuff into the tank of my 40k van, I gave the stuff a "jolly good Google" , as I am just as sceptical as anyone! From my "jolly good google" I have concluded that it is likely that Dipetane increases the lubricity quite dramatically. That is a good thing and given the manufacturers claims I don't see the harm in using it. Dipetane Advanced Fuel Treatment is a fuel additive that is designed to improve fuel economy, reduce emissions, and protect your engine. It is a unique blend of hydrocarbons that helps to clean and lubricate your engine, and it also helps to improve the combustion of your fuel. This can lead to significant improvements in fuel economy and emissions. They therefore represent the maximum benefit experienced. Having analysed the data carefully, in my view it is fair to quote the maximum benefit experienced. This is so as each data set is small, being gathered only over seven days of testing and variable ranges of 90¬600 km per day, it shows continuing improvement and does not reach steady sate, see Figure 3. The exception to this is bus # 7-79148, where fuel economy data for a 1 week "cleansing" period at 600 km/day is also provided. The data show that continued improvements in day-to-day fuel economy are noted in each of the seven days. This would indicate that it takes time for the Dipetane fuel treatment to totally replace the normal fuel; coating of the fuel handling and engine apparatus etc. Figure 3 presents the normalized fuel consumption for each bus with days of use. In all cases the data show a continued improvement in fuel economy with consecutive days of use, up to and beyond at least 3-4 days. I'm only trying it as I trust the judgement of my colleague when it comes to anything related to diesel engines. Answers to your questions about Dipetane
Q.Does Dipetane really work?Latest Reviews
Your vehicle’s Engine Management System handles cleaning the DPF. This occurs automatically when the vehicle is able to maintain a high engine load for a certain amount of time, such as on a long highway drive. Under these conditions, exhaust temperatures are high enough to vaporise or convert the soot particulates into CO2, allowing them to be safely released from the exhaust system. A.Dipetane treated fuels burn more completely and more fuel is converted to energy, resulting in better fuel economy. It has been proved that Dipetane can help achieve up to 10% better fuel economy, representing definite cash savings. Any technology that reduces the extent of soot production will have large advantages to the engine efficiency, cleanliness, and to fuel economy. Examination of Biofuels Claims A.Currently all the major Oil Companies use detergents added to standard fuels to wash away the unburnt carbon as opposed to burning it. Dipetane encompasses the only known fuel technology that facilitates the proper (more complete) combustion of carbon in the fuel.
