Durability of Diesel Fuel: Storage Lifespan, Chemical Reactions, Injector Effects in CR Engines

Question

Hello,
question about the durability of diesel fuel. How many years of ON can be stored without loss of quality, what happens after long storage (chemical reactions, precipitation of ingredients, etc.)?
The injectors are probably the most exposed to too poor quality (old) diesel fuel - electric injectors, of course. ON will be used in modern diesel engines with CR injectors and a turbine.

You probably mean diesel, not crude oil, so correct the subject.
On the subject, if you want to pour old CR diesel fuel, I do not predict a long mileage of this diesel engine.
I just don't know how long the ropka has matured - probably a few months so it will go to the old clatter, but I would rather not pour the new one.

After about 3 months, a good amount of water is removed from such oil.

robokop · Accepted Answer

decibel 91 Explain to me, how is that? If the vessel is closed, it can stand - after a few years of ethylene, there was sediment, and after ON, I did not notice anything disturbing after a year or two in the tanks.

decybel91 · Answer

Moisture will always get into even a closed tank.

robokop · Answer

That's why you have separators in the filters. Anyway, what are you talking about - ask someone who has dealt with tanks at petrol stations, he will tell you how much water is in them.

miler80 · Answer

Especially as it is stored in a metal tank.

Pascalt · Answer

Since water, the injectors will not get the most, as it seems to me - the water is not compressed to a large extent.
According to what you write - diesel fuel stored for 3 years in a metal barrel would not be usable anymore.

DoktorB · Answer

ON durability is 6 months (manufacturer's warranty for meeting the requirements of EN 590).

Alfred_92 · Answer

After all, there will be small amounts of this water, not liters, so the presence of such an amount of water in the combustion chamber will not be noticeable. Just out of curiosity, the water in the combustion chamber turns into a water jet under the influence of temperature and facilitates even distribution of the mixture in the cylinder in order to obtain an even temperature distribution. Such solutions are used in marine engines by using separate water / steam injectors or by using dual-function injectors.

strucel · Answer

Gentlemen, water in a small amount is not a problem, but the products that are made from "eating" biocomponents added to the fuel by bacteria. Unfortunately, the fuels currently sold in comparison to those from several years ago are embarrassing.

I wonder what the army stores? I assume industrial quantities.

robokop · Answer

Theoretically, every specified period should be tested for physicochemical changes in the content and replaced. A ekhmmm is stored. War stocks in the so-called bunkers - in unified standard 200l barrels, ready for distribution to vehicles, and larger amounts for later in steel underground tanks. Such a tank has probably two layers of steel, plus a bitumen coating on the outside.

Fidelis · Answer

I am more interested in the composition / quality of ON stored by the army. Somehow I find it hard to believe that in these warehouses the fuel is changed after 6 months.

robokop · Answer

There is such a thing as the Research and Development Center of the MPS Service, which examines the stored fuels and lubricants. If the delivered sample is classified as non-compliant, the fuel in the tank is replaced. And this is not only diesel and gasoline - aviation fuel, kerosene, a whole range of lubricants (i.e. greases and oils).

Fidelis · Answer

After what time in practice are the fuels (gasoline or diesel) replaced? Does the fuel have these critical biocomponents?

manta · Answer

The fuel is not changed, and chemical changes, especially in the case of military vehicles, are not a problem. Most vehicles have multi-fuel engines. So they can be powered by everything that is burning, the issue of generated power remains. Most vessels try to use the stored fuel when maneuvering, adding fresh fuel as a supplement.
As for civilian engines, they have much higher quality requirements. Here, unfortunately, the manufacturer actually specifies the durability for six months. I often run cars on fuel older than this period and I must say that the engines are not working properly. Topping up fresh will improve the situation considerably.

Fidelis · Answer

I heard that one of the tank models (T-55?) Can be flooded with completely unrefined oil. I don't know how much truth there is. It occurred to me to buffer 80-100l ON for 1.9 SDI (Skoda). And I wonder if it is safe ... I mean, will I not hurt the engine (although simple in design). Possibly until when maximally (as successively) this buffer use / replace. If I was consistent (i.e. not lazy), the buffer would be replaced after (up) 3 months. The question is, where does this requirement come from? Due to admixtures of biocomponents versus established by the standard quality requirements? Because maybe it is just a whim ordered by the producers by the all-powerful one of those looking to justify their existence by the EU commission?

manta · Answer

Read the last sentence of my post, I don't know if it's about bio, but what I wrote comes from practice. SDI will work, but will it work normally? It will light, it will go, power and acceleration ... like a medicine. For this unknown changes in the injection system ...

Fidelis · Answer

It's SDI. So the wife has power and acceleration for medicine and fresh fuel Does not complain. OKAY. Of course. You wrote a sentence earlier about the used fuel OLDER than 6 months

Stermotorzysta · Answer

Maybe not exactly what the topic is, but I think it's worth it.
We had a case that after a summer break (about 4 months) the burner of the central heating boiler in the company did not want to light - despite cleaning, changing the filter, the nozzle did not light. Only after replacing the fuel oil in the tanks with the "new" burner, the burner fired. The company that supplies the oil stated that it is best to store such oil for a maximum of 3 months ...

Looking at the oils in the tanks, they did not differ completely from each other ...

Fidelis · Answer

Interesting ... maybe I was lucky that for two years, without failure I used a 30l tank of gasoline (regular 95k) in a generator exposed to frost and heat. Without refilling the fuel, adding any improvers or mixing with fresh fuel.

After all, it is home to bacteria which a nice mushroom can effectively clog the siti at the pump / dragon inlet in the tank. I wonder how they fight it in the ministry?

The development of microorganisms in fuel systems causes a number of processes that adversely affect the power systems and the quality of the fuel in them. These include: clogging of filters and fuel lines, blockage of injectors, corrosion of the tank and fuel lines, decomposition of hydrocarbons and additives, increase in the content of water and sulfur in the fuel, formation of deposits and suspended solids in the fuel, and the production of surfactants causing emulsification of the fuel . The occurrence of these phenomena results in a decrease in engine efficiency and greater wear of its components.

Ermax · Answer

Easy, if it is tightly closed, it can be safe for 2 years. As for the mixing of diesel or gasoline with water, I recommend going back to primary school for Physics / Chemistry and not to shit such nonsense. When it comes to nap. of course, the one that does not contain biocomponents is definitely better and can be aged for up to 5 years (it does not become cloudy and no sticky precipitates). So, buddy, if you have a clean, greasy diesel, it's funnel and don't worry ...

321ziko · Answer

For several years I have been buying diesel in winter as a reserve for the whole year for vehicles with Common Rail. I have noticed that in two years there is less sediment in a form similar to chocolate pudding. The reason for the lower amount of sludge is the reduced or lack of bio additives in the winter due to the large number of complaints from transport companies for winter fuels. I have the information from an employee of the fuel company.

Fidelis · Answer

On the filter? At the bottom of the tank?

321ziko · Answer

At the bottom of the 1000-liter tank, 8 months after the purchase (gas station purchase), I start using the fuel. It digs 3 thousand liters annually.

stasiekb100 · Answer

Gasoline may not age so much and paraffin does not precipitate out of it. He's only fresh, old, worth nothing, you can light a fire in the furnace. The old one smokes 1.5 times more and there are still problems with the injectors.

Fidelis · Answer

I don't know if it's a matter of aging, but out of the 6 plastic canisters (20L), 2 were noticeably swollen. It turned out that the vapor under pressure had collected (unlike the others). A puzzle, because the fuel was bought at the same petrol station at different times ... What does fresh mean and where does this conclusion come from? I use about 8-9 months of diesel fuel and I do not see ANY difference, also in the degree of wear (SDI engine). But without exaggerating with smoking in the fire ...

stasiekb100 · Answer

Maybe you get a better one. It also depends on how it is stored, i.e. stored at a constant temperature, mixed, without exposure to frost. You buy a winter one and use it in summer. I bought it in late autumn, everything was fine at first, but by spring the car was burning from 6.5 out of 100 to 10 out of 100 and it stopped working on one cylinder (it just passed the same).
