The Ministry of transport of the United Kingdom is seriously committed to providing gasoline E10 (that is such that contains 10% bioethanol) status main fuel of the country. And petrol with lower content of bioethanol (E5, which is currently the most common in the United Kingdom) will be available only in the form of high-octane (similar to our 98-th gasoline).
And all anything, only 10 percent of gasoline in Britain will not be able to drive about 1 million cars. The engines of cars produced after 2011, can easily burn E10, but those that were made earlier could be affected. Biofuel has a high Stripping property, and deposits in older engines and fuel systems can cause clogging of the entire system. Additionally, biofuels are also more actively reacts with certain materials, so its use is fraught with corrosion, seals, plastics and metals.
The fact of the unsuitability of such fuel for some vehicles directly spelled out in government-provided documentation: “today, in Britain was about one million vehicles for which the manufacturer does not recommend the use of E10 gasoline”. But then follows the information that by 2021 the projected number of vehicles that support this type of gasoline will be equal to 98%.
On the other hand, when E10 gasoline is burned, the atmosphere gets 2 percent less CO2 than burning the same amount of E5 (the biggest percentage distribution of oxygen promotes better combustion of the fuel). According to rough estimates from the Ministry, the effect of the substitution of one gasoline the other is equal to the removal from roads of 350 thousand cars. This fact is the cause of the widespread transition to another type of gasoline in Britain.
In the context of the discussion of this decision, the head of the Royal automobile club (RAC Foundation) of great Britain Steve Moody (Steve Gooding) so described the situation: “Even a few years on the roads will still be several hundreds of thousands of cars engines that are incompatible with E10 fuel”. A logical extension of this idea is to reduce emissions now, even if it would create discomfort to a million British drivers.
