Faced with tremendous pressure to reduce CO2 emissions by 40%-45% in 2020, the development path of Chinese engine companies has become the most concerned issue in the industry. On December 23, at the “China Engine Independent Innovation Summit Forumâ€, all the experts expressed their opinions, and the road to low-carbon development in the engine industry was more ingenious. At the meeting, Li Qingwen, president of China Automotive News and editor-in-chief of China Energy News, Fu Yuwu, executive vice chairman and secretary general of China Automotive Engineering Society, Dong Chunbo, deputy general manager of FAW Group Corporation, deputy chief engineer of FAW Group Co., Ltd., and director of technical center Li Jun, Executive Vice Chairman and Secretary General of China Internal Combustion Engine Industry Association Xing Min, Qian Hengrong, Director of FAW Wuxi Diesel Engine Factory, Deputy Director of the State Key Laboratory of Automotive Safety and Energy, and Song Jian, Deputy Director of Department of Automotive Engineering, Tsinghua University, delivered a keynote speech . Engine industry faces low carbon problems The Copenhagen climate conference was over. However, many people are still pondering the splendid speech of Premier Wen Jiabao. “From 1990 to 2005, the intensity of GDP per unit of GDP dropped by 46%. On this basis, we also proposed that by 2020, The GDP of China’s GDP has dropped by 40%-45% compared with 2005. ... We must be convinced and behave in a meaningful way. No matter what results we achieve at this meeting, we will unswervingly achieve and even exceed this goal. Efforts.†Premier Wen Jiabao’s remarks not only demonstrated the attitude of a responsible big country, but also caused many domestic industries, especially the engine industry, to feel the pressure of continued development. Song Jian, deputy director of the State Key Laboratory of Automotive Safety and Energy, and deputy director of the Department of Automotive Engineering at Tsinghua University, said: "Although the proportion of domestic automobile carbon dioxide emissions to total carbon dioxide emissions is not high, it is only about 5%, but the Chinese automobile ownership Rapidly increasing the proportion of carbon dioxide in automobiles has increased dramatically, and the automotive industry, especially the engine industry, must work hard to implement national emission reduction targets." Qian Hengrong, director of FAW Xichai, said with concern: “The speed and impact of climate change are more serious than expected. I believe that responsible companies should actively implement a low-carbon economy and consider it a corporate development goal.†The reporter learned that in 2008, the atmospheric carbon dioxide content reached 385.2ppm, a record high, an increase of 38% over 1850. The increase in carbon dioxide content has caused global warming, resulting in difficulties in water supply in some countries, particularly in Africa. It has also led to an increase in sea level and a reduction in the size of several island countries. Many agencies expect that at this rate of development, sea levels will rise by 1.4 meters by 2100, and there will be danger of submergence in many island countries and coastal cities such as New York and Shanghai. Xing Min, executive vice chairman and secretary-general of the China Internal Combustion Engine Industry Association, pointed out that the combustion of coal and petroleum is the main source of carbon dioxide, and the automobile is the main source of oil consumption and the main source of greenhouse gases. Compared with developed countries such as Europe and Japan, China's vehicle engine oil consumption is 10-15 percentage points higher, and there is still more room for CO2 emission reduction. It is understood that the "Limit Rate of Fuel Consumption of Passenger Cars" implemented on July 1, 2005 stipulated that the fuel consumption of new cars after 2009 will be reduced by 15% compared with 2004, equivalent to 160-170g of CO2 emissions per kilometer. Europe's CO2 emission level per kilometer is only 140g. China will achieve 40% to 45% of its CO2 emission reduction targets by 2020 and put forward stringent requirements for Chinese engine companies. Qian Hengrong said: “In 2009, China produced approximately 13.4 million vehicles, with a total capacity of approximately 7.18 million vehicles, and it is expected to have more than 100 million vehicles in 2020. If 40%-45% of emission reduction commitments are achieved, then vehicle fuel oil The economy needs to increase by more than 20%." The coping strategy of low-carbon engine era "In 10 years or so, we will increase the fuel economy of automobiles by 20%. This places very high technical requirements on the automotive industry, especially the engine industry," said Li Qingwen, president of the China Automotive News and chief editor of the China Energy News. Through the introduction of Qian Hengrong, the reporter learned that there are many possible ways to achieve the goal of reducing carbon in China. First, speed up the upgrading of traditional engine technologies, such as the use of supercharged or supercharged intercooled technology, to improve the combustion efficiency of diesel engines; use a highly efficient fuel injection system to improve the combustion process; and further optimize the combustion system to improve engine economy. Relevant data show that through several improvement measures of the engine, it can increase fuel economy by 8%-14%. Song Jian said: “Engine companies, especially domestic diesel engine companies, must master supercharger technology, which can significantly increase engine efficiency. With a well-matched booster system and a complete vehicle, the vehicle can save about 10%. It is also very effective to increase the efficiency of engine transmission." Second, diesel engines and diesel-electric hybrid systems were promoted. At present, diesel engines save about 30% more fuel than conventional gasoline engines, about 25% more than direct-injection gasoline engines, and 35-40% less diesel-electric hybrids than gasoline engines. Therefore, it is significant for China to promote diesel cars and diesel-electric hybrid cars. Many experts told reporters that the European car's carbon dioxide emissions are at the leading international level, mainly because Europe is mainly based on diesel engines and is developing in the direction of diesel-electric hybrid power. In 2015, the United States and Japan can only emit 155g of carbon dioxide per kilometer, while Europe can reach 130g per kilometer. Third, we will develop dedicated engines for alternative energy sources. Many countries in the world are exploring the use of alternative energy sources as fuel for engines. For example, China has promoted CNG, LPG, and methanol fuel to a certain extent. Brazil and the United States have used E85 (85% ethanol and 15% gasoline as a mixture. Fuels have a soft spot. Germany and Sweden have invested more energy in the development of biodiesel and biogas. Many vehicle and engine companies in China are researching alternative energy sources. Since alternative energy sources are low-carbon energy sources, they can reduce carbon dioxide emissions by 20%-30% while maintaining engine power. Qian Hengrong emphasized: “Alternative fuels are an important way for the sustainable development of diesel engines. On the one hand, some alternative fuels have abundant reserves, such as the availability of natural gas with huge reserves of combustible ice; on the other hand, the compatibility of certain alternative fuels with diesel engines. Well, the industrial chain is relatively complete, such as alcohol fuels." Song Jian reminded: "The principle of energy conservation of alternative energy is relatively clear, but the premise is to use a dedicated engine. At present, China's research and development in the dedicated engine lags behind, such as Guangzhou LPG bus has been promoted for many years, there is no LPG engine." Fourth, develop hybrid engines. Qian Hengrong said that hybrid power is another important way for the sustainable development of diesel engines. The technical risk and investment of the micro-combustion diesel engine are relatively small, it can save 3% -6%, light mixing can save 10% -15%, and the medium-blending and heavy-mixing is the future development direction, which can save 15% -40%. Traditional engine upgrade is the top priority There have been pessimistic expectations that oil resources will eventually be depleted, and the lifespan of engine companies will not be too long. Faced with these unfavorable words, Qian Hengrong firmly stated: “The engine industry can develop for at least 30 years.†Fu Yuwu, executive vice chairman and secretary-general of the China Automotive Engineering Society, said: “In the next 20-30 years, automobile power will also With the upgrading of engines, especially diesel engines." Qian Hengrong told reporters that from the perspective of the entire process, the entire industry chain, and the entire life cycle, diesel engines are by far the most effective power plant. In terms of overall efficiency, the overall efficiency of traditional engines is 30%-45%, which is higher than 25%-30% of pure electric vehicles and also 20%-25% higher than that of fuel cell vehicles. In addition to the advantages of traditional engines with high maturity and high efficiency, Qian Hengrong emphasized that the earth also contains abundant petroleum and other petrochemical resources, and at least 40 years of mining, the development of diesel engines represented by the traditional automotive power systems (including firewood Electric hybrid systems still have broad prospects. In response, the reporter interviewed professionals in the oil industry and disclosed that: "In the past 10 years or so, the proportion of the total amount of oil already extracted in the world to the total amount of proved oil has not only not decreased, but has also increased. It shows that there is still much room for human understanding of oil resources. We must have confidence in the future development." In Home Lighting Co., Ltd , http://www.dg-ledlight.com
