Ethanol gasoline for vehicles, which has been widely accepted by the general public in the United States and other countries for nearly 30 years, has been repeatedly abused in the promotion of some regions in China. The unsatisfactory response of various sectors of the society to the different reactions of fuel ethanol, the different attitudes of users to the use of fuel ethanol, and the unsatisfactory market sales situation are confusing. This reporter recently conducted an interview investigation. From March 8, 2002, the state began to promote the use of ethanol gasoline in the five cities of Nanyang, Zhengzhou, Luoyang, Heilongjiang, Heilongjiang and Heilongjiang, replacing the 90# and 93# regular gasoline used previously. On February 10 this year, eight ministries and commissions, including the National Development and Reform Commission and the Ministry of Finance, jointly issued the "Experiment Plan for Expanding the Use of Ethanol Gasoline for Vehicles", requiring that the scope of the trial be extended to nine provinces, including Liao, Ji, and Hei. Ethanol Gasoline significantly reduces tail gas emissions without causing any impact on automobiles. It also relieves the country’s excessive dependence on petroleum resources and opens up a new road for the industrialization of grain utilization. It has long been widely used in the United States and Europe. However, the owners of the pilot areas in China did not respond to it. The consumer's problem mainly focused on whether the use of ethanol gasoline would harm the vehicles designed on the basis of the principle of gasoline. This worry made the promotion of ethanol gasoline slow in some areas. Whether or not to corrode parts of the country's leading group for the promotion of ethanol gasoline, Professor Qiao Yingbin explained that ethanol gasoline contains only 10% of alcohol, and added corrosion inhibitors, it can be said that the metal parts will not cause any corrosion. Qiao Yingbin admits that ethanol does cause certain swelling in rubber and plastic components such as oil pipelines, but this will not cause much impact and can be replaced by more chemically stable fluororubber components. Whether there is insufficient power Xu Tamming, an engineer at the China Automotive Technology and Research Center, frankly stated that the combustion calorific value of ethanol is actually lower than that of gasoline. The calorific value after 10% blending is 3.8% lower than that of pure gasoline, but due to the oxygen content in the blended fuel. With the increase, the combustion of carbon monoxide and hydrocarbons as tail gas will be more complete, thus increasing the heat by 2.3%. The balance between the two, the use of ethanol gasoline only brings little loss of power, or even barely noticeable. Sun Delong, head of the Chinese section of the Shanghai Volkswagen Product Engineering Division, told reporters that the use of gasoline supplemented with 10% fuel ethanol will not affect Shanghai Volkswagen's automobiles. The price can be cheap According to Henan Provincial Development and Reform Commission Chen Dahong, in Henan's pilot work, the reason why ethanol gasoline is quickly accepted by consumers and recognized, a very important reason is that the price of Henan ethanol gasoline per liter The same type of regular gasoline is 0.1 yuan cheaper. However, in other pilot regions, the retail price of ethanol gasoline is the same as that of regular gasoline in the non-pilot areas around it. This has greatly reduced its market competitiveness and led to pilots outside of the trial where regular gasoline flows into some pilot regions. At present, the State stipulates that the ethanol gasoline blending center purchase fuel ethanol in accordance with the ex-factory price of 90# regular gasoline multiplied by 0.9111, but in addition to the cost and related expenses in the deployment center, the gas station will enter the 90# and 93# ethanol gasoline for vehicles. The wholesale price is a few hundred dollars higher than the regular petrol wholesale price per ton, resulting in a drop in gas station profit, which also brings great passiveness to the promotion of ethanol gasoline. Resolving Chenhualiang’s efforts to promote ethanol gasoline is not only because it is a new type of fuel, it can bring huge environmental benefits to the country, but also because it can effectively alleviate the enormous pressure caused by the shortage of oil resources. Wang Wei, Director of the Industry Division of the National Development and Reform Commission, said that the more important role of ethanol gasoline is to provide a new outlet for the transformation of agricultural products. He calculated for the reporter that the 19,000 tons of ethanol consumed by the 200,000 pilot cars in Henan province was obtained after eating 67,000 tons of Chenhuan grain. This also means that the state finances each year The subsidies for releasing grain and grain in stock can be reduced by 13.5 million yuan. It can be said that the development of ethanol gasoline provides a good way for the industrial utilization of some varieties of grain, and it also creates the possibility for farmers to increase their income. Ethanol as an engine fuel began in the 1930s. Since the 1970s, due to the impact of two oil crises and restrictions on automobile exhaust emissions, some countries with scarce oil resources and densely populated countries have passed legislation and encouraged policies to encourage the use of alcohol fuels (mainly ethanol) as a vehicle gasoline blending group. Minute. In 1979, the United States began to promote the use of mixed fuel containing 10% (V/V) ethanol. In 2003, 41 states in the United States consumed more than 50 million tons of ethanol. In Brazil, as early as 1930, Brazil used ethanol at a rate of 5% to 15% (V/V) for gasoline.
Mode locked series lasers are features of superior beam quality, best reliability, and the pulsed duration of mode-locked and picosecond Pulsed Laser could be less than 20 ps. Housed in compact packages, they are the perfect choice for design in and integration into OEM instrumentation and systems and also for end user applications in research and development. They are widely used in raman spectroscopy marking, carving, material processing astronomy and scientific research optical instrument.
