Ji'nan, Liaocheng and other 8 cities to promote ethanol gasoline or will be extended throughout the province.
to adjust the energy structure and improve the quality of the atmospheric environment. Recently, the legal office of the Shandong provincial government published the "draft for the promotion and use of ethanol gasoline for car use in Shandong province", which mentioned in Ji'nan, Zaozhuang, and Zaozhuang. The use of ethanol gasoline in Tai'an, Jining, Linyi, Dezhou, Liaocheng, Heze and other administrative areas can also be popularized and used in other administrative areas to promote the use of vehicle ethanol gasoline in other administrative areas.

2006, seven cities have closed the use of ethanol gasoline
say car ethanol gasoline, in fact, it is not strange to it, this is a national standard, with the use of denatured fuel ethanol and mixture of gasoline to form a clean fuel. The promotion of ethanol gasoline can not only save oil resources, but also reduce the pollution of automobile exhaust. Therefore, the United States and many other countries have been promoting the use of ethanol gasoline many years ago. In recent years, the frequency of haze has not been frequent. Many provinces in China have gradually started to promote the use of ethanol gasoline for vehicles.
reporter learned from the provincial government that, as early as 2005, the "method for the promotion and use of ethanol gasoline for car use in Shandong province" had been released and formally implemented in January 8, 2006. At that time, the regulations stipulate that the 7 cities in Ji'nan, Zaozhuang, Jining, Tai'an, Liaocheng, Linyi and Heze will promote the use of ethanol gasoline for vehicles. It is forbidden to sell other vehicle gasoline fuels other than ethanol gasoline. According to the state regulations, local refineries in closed areas should not sell regular gasoline to local customers.
market sales are not good, ethanol gasoline basically retreated
reporter learned that after the listing of ethanol gasoline, the price has been less than 5 cents lower than the high clean gasoline, but the market sales are not optimistic. According to statistics in 2012, gasoline consumption in Shandong ranged from 800 to 9 million tons, of which 1 million 300 thousand tons of ethanol gasoline accounted for less than 20%.
for the market, some owners said to reporters, "the lack of ethanol gasoline in the burning value, power and corrosion resistance is the main cause of its abandonment." It has been shown that the calorific value of ethanol is 60% of the ordinary gasoline, and the fuel consumption of the engine will increase by 5% if the car does not make any changes and uses 10% of the mixed gasoline containing ethanol.
and now there are few petrol stations in Ji'nan still selling ethanol gasoline. In several other cities that were popularized at the time, there were still a few gas stations in Liaocheng selling ethanol gasoline, but gas station workers told reporters that few owners were willing to add ethanol gasoline. "Many people come to fuel to don't have ethanol gasoline."
if it is necessary to push out
in the whole province, the revised draft will also add a new clause: "according to the needs of the work and the decision of the provincial people's government, the use of ethanol gasoline in other administrative areas can be used." This also means that vehicle ethanol gasoline can not only be popularized in the above 8 districts, but also be pushed across the province if necessary.
perspective
vehicle ethanol gasoline
[advantages]
- high octane number and good antiknock ability. With high oxygen content and 10% ethanol in gasoline, oxygen content can reach 3.5%. Oxygen combustion, that is to say, oil burning will be more sufficient.
effectively reduce vehicle exhaust emissions. Domestic research shows that E15 ethanol gasoline (ethanol content in gasoline is 15%) is 16.2% lower than that of pure lead-free gasoline, and carbon monoxide emission is reduced by 30%.
fuel ethanol has rich production resources and mature technology.
[defect]
the calorific value of ethanol is 60% of conventional vehicle gasoline. In some college vehicle experiments, the fuel consumption of the engine will increase from 5% to 7% if the car does not make any changes and uses the mixed gasoline containing 10% ethanol directly. The evaporation temperature under the theoretical air fuel ratio of
ethanol gasoline is greater than that of conventional gasoline, which affects the formation and combustion speed of mixed gas, which leads to the decline of automobile power.
alcohol is a good solvent, which is easy to produce mild corrosion, swelling, softening or cracking of automobile sealing rubber and other synthetic nonmetallic materials. The impurities dissolved in the plug blocked the oil circuit, and sometimes they would not start firing after two times.

to promote the use of a new way to delineate 8 cities, and the new Dezhou
this time, Shandong has revised the method. Recently, the government legal office of the provincial government has released the "method for the promotion and use of ethanol gasoline for car use in Shandong province" ("the draft amendment draft").
combing reporters found that the revised draft of the aforesaid method has many changes compared with previous methods. In the revised draft, it will increase the use of ethanol gasoline to 8 areas, the 8 cities are Ji'nan, Zaozhuang, Tai'an, Jining, Linyi, Dezhou, Liaocheng, Heze and Dezhou.
experts believe that the promotion of the use of ethanol gasoline to delineate 8 cities is mainly concerned with improving the air quality of the 8 cities.
