At first, buying fever was the cause and not a shortage of supplies, but today all distributors are spreading their hands when someone is looking for this liquid. The problem is nearly 300 thousand cars, approx. It could affect 100,000 light commercial vehicles, nearly 5,000 buses, 33,000 trucks and heavy goods vehicles. Mol answered Telex’s question: there are no significant stocks in stock, if the situation consolidates on the manufacturer’s side, supply may improve. Although AdBlue electronics can be circumvented, vehicles can cause serious pollution.
While diesel-powered models accounted for only one-fifth of the total European car market in the last quarter (half more in 2017), diesel will continue to predominate in light and heavy trucks and buses for a long time to come. Therefore, it is not incidental that the AdBlue additive, which is essential for the operation of modern diesels, has run out in the whole of Europe, including Hungary, in a matter of days, and according to the distributors, the situation is not expected to settle for two weeks. In Budapest Kauffer store employee, Gábor Prokop reported that the purchase price of AdBlue doubled in one week. The material arrives in smaller quantities, and despite the significant price increase, it is all taken away by customers immediately, with demand just jumping tenfold compared to last year. The company is currently unable to provide a 10-liter package, and the 1.89-liter Volkswagen-packed liquid costs HUF 6,500.
It is important from an environmental point of view
The New Word news portal last Tuesday’s article According to the Duslo chemical plant in Vágselly, one of Europe’s largest AdBlue producers will not take new orders due to the significant increase in the international market price of natural gas used for the production of liquids. In addition to the company, a Polish and a German factory, among others, are dealing with this product, but they have also limited production or stopped it, which could soon cause serious problems in freight and passenger transport.
Under its trade name, AdBlue is actually a high purity liquid containing 32.5 percent urea and 67.5 percent deionized water. They are stored in a separate tank in models equipped with Euro 5, but mainly Euro 6 environmental grade diesel engines, which are the constructions of the last ten to fifteen years. The fluid is supplied by the selective reduction catalyst during separate engine operation (SCR – Selective Catalytic Reduction) AdBlue entering the unit, the SCR preheated to 250 degrees Celsius, releases ammonia under the influence of heat and then interacts with the nitrogen oxide components of the exhaust gas and decomposes them into nitrogen and water, respectively.
It affects hundreds of thousands of vehicles
At our request, Datahouse, which deals with the analysis of the state vehicle register, looked at the total number of vehicles in the various categories that could be affected by the sudden AdBlue shortage in Hungary. According to their statement
- 6% of the 4.1 million passenger cars are Euro 6 rated, representing 247,000 units,
- almost a fifth of the half a million light commercial vehicles need the additive (about 100 thousand),
- for the 18,000 buses, this proportion is already 27 percent (4860),
- however, one in three of the approximately 100,000 heavy trucks already uses AdBlue (approximately 33,000).
Although the above are inaccurate values, as in several cases a small proportion of previous Euro 5 cars were fitted with the system, in fact, for some time some car manufacturers met the latest environmental standard (Euro 6d Temp and Euro 6) without applying the technical solution, with a few exceptions today, all new diesels run on AdBlue. This means that this system is mandatory for cars after 2010 and for trucks and buses after 2008 (Euro V and VI).
The AdBlue tank of a modern car has a volume of 15-20 liters. On average use, ie with a mileage of 15-20 thousand kilometers, it only needs to be topped up annually, as a typical car consumes an average of 1-1.5 liters of fluid per thousand kilometers. However, when the tank is empty, the engine control electronics switch to emergency mode after several warnings, ultimately not allowing the engine to start until the tank is empty.
Mol has no stockpiles, the Slovaks reserve for their own purposes
Nowadays, many cars have been questioning the well operator in vain, as in a few days the liquid, which is typically available in a five-liter canister and can be filled on a separate well column, has disappeared from almost everywhere. In recent days, I’ve been to five high-traffic gas stations in Budapest, and we were interested in OMV at the entrance to the M1 and M7 motorways, Mol wells in Buda, or Shell filling stations, they said everywhere: otherwise depleting stocks for one to two weeks.
I also asked Mol’s communications department about the case. According to their responses on Friday, the company basically does not have significant stocks of AdBlue additive, as resellers receive steady balances from European factories. As they claim, Mol has so far been able to provide full supply, but the press reports of the last few days have really multiplied customer demand, a takeover has started, which has upset the Hungarian market and caused a temporary shortage. As the situation consolidates on the producer side, Mol expects demand and supply to balance in the medium term.
It is difficult to say exactly when this will happen today. The problem is complicated, as New Word announced Tuesday Tuesday to Economy Minister Richard Sulík that the State Reserve Fund plans to buy 500,000 liters, while the Slovak state has agreed with manufacturers and distributors that AdBlue will be sold exclusively to local carriers.
The electronics can be played
The complex electronics of cars and trucks and buses equipped with the AdBlue dosing system and SCR can be bypassed, as the command line for checking the additive level and disabling the engine start when the tank is empty can be bypassed via the standard on-board diagnostic connector, OBD. AdBlue emulators for this purpose have been available for a long time, they are offered for trucks for 10-20 thousand forints, but their distributors usually draw attention to the fact that the emulator is not a final solution, but as stated on the eMAG page, the goal is to
“For example, on a foreign trip, in a place where the price of the liquid is many times higher, you could go to a cheaper place, on the highway.”
The illegal method does not damage the engine, but when a diesel equipped with this environmental solution is used without AdBlue, its nitrogen oxide emissions jump significantly, so it does not meet the requirements of its official classification.
