Until now, new energy vehicles that have been placed on high hopes and invested heavily in energy-saving and emission reduction have not achieved the desired results. In particular, electric vehicles, the National People’s Congress mobilized the general public and did not allow it to enter the homes of ordinary people. The Chinese government has realized that waiting for a new energy vehicle, the “saviorâ€, is not reliable, and it needs to change the current situation. In the haze of the entire north, upgrading of internal combustion engine products is a top priority.
On February 17, the State Council issued the Opinions on Improving the Energy Saving and Emission Reduction of the Internal Combustion Engine Industry. By 2015, energy-saving internal combustion engine products accounted for 60% of the entire society's internal combustion engine products; compared with 2010, the fuel consumption rate of the internal combustion engine was reduced. 6% to 10%. China will study and formulate financial support policies for promoting energy-saving and environment-friendly commercial vehicles, improve tax-reduction policies for energy-saving and environment-friendly internal-combustion engine products, and retire old subsidies for agricultural machinery to promote energy-saving and emission-reduction of agricultural machinery. The "Opinions" also proposes that during the "12th Five-Year Plan" period, China will cultivate a number of remanufacturing key enterprises such as engines for automobiles and construction machinery, and realize localization and large-scale production of energy-efficient and environmentally-friendly internal combustion engine main engines and parts and components manufacturing equipment. The establishment of internal combustion engine energy-saving and emission reduction policies and regulations and standards system.
The "Opinions" cover 11 key areas of support, namely, passenger car engines, light vehicle diesel engines, diesel engines for medium and heavy commercial vehicles, diesel engines for non-road mobile machines, marine diesel engines, general-purpose small gasoline engines, and gasoline engines for motorcycles. Wait. For these areas, China will implement six demonstration projects to promote the reduction of energy consumption of different types of internal combustion engines. The "Opinions" emphasizes that the backward production capacity expansion will be curbed, strict implementation of the elimination of outdated product systems, improvement and strict implementation of the environmental protection type approval system for motor vehicles and engines, and emission standards for motor vehicle pollutants, as well as the release of the promotion catalog of energy-saving products for internal combustion engines, and development of implementation plans Speed ​​up the promotion and application of advanced energy-saving internal combustion engine products.
According to statistics from the monitoring data of the Institute of Atmospheric Physics, Chinese Academy of Sciences, in January 2013, a total of five strong pollution processes occurred in Beijing, Tianjin and Hebei. Throughout January, a total of 22 days of PM2.5 exceeded the national standard for secondary air quality standards to be implemented in 2016 (75 μg/m3), and 27 days exceeded the national standard (35 μg/m3). 4 days of fine weather, the Beijing-Tianjin-Hebei air pollution situation is very grim. According to the latest research results of the “Special Group on Recovery and Control of Atmospheric Hazeâ€, a large number of nitrogen-containing organic particles were detected during haze.
For this reason, the Opinions require that by the end of 2015, nitrogen oxide emissions will be reduced by 10% compared with 2010. In addition, by the end of the “Twelfth Five-Year Planâ€, it will reduce carbon dioxide emissions by 62 million tons and use alternative fuels to save 15 million tons of commodity fuel oil. Specific to the passenger car engine, we must focus on promoting the use of direct injection technology, encourage the following 2.0 liters displacement, especially 1.6 liters below the small displacement gasoline engine using pressurized and direct injection technology to promote lightweight technology. By 2015, all production diesel engines will use high-pressure fuel injection systems. The fuel consumption rate will be reduced by 5% to 8% compared with 2010. In addition, 30% to 40% of newly-produced gasoline gasoline engine products use direct injection fuel systems. The fuel consumption rate was 8% to 10% lower than in 2010.
As one of the earliest turbocharged companies, the “TSI+DSG†gold powertrain made the public stand out. With the maturation of turbocharging technology, GM and Ford have begun to adopt this technology widely. Among them, The Regal 1.6T, Malibu 1.6T and Cruze 1.6T are the hot models of Shanghai GM. New Mondeo and New Focus are also sought after by consumers because of the new powertrain. After the old powertrain was criticized, Dongfeng Citroen and Dongfeng Peugeot have also been reinvented since last year. The new models C4L and 3008 both use 1.6T turbocharged engines and dual clutch transmissions.
In the upgrading of internal combustion engines, the independent brands are not behind. Among them, companies including Chery, BYD, and Geely have also launched their own turbocharged engines and dual-clutch gearboxes. "The turbocharger is actually an air compressor that increases the intake of the engine by compressing the air." Industry insiders said that the full development of the turbocharged brand is not only a new bright spot but also a new competitive opportunity. Among them, BYD G6 is equipped with a new generation of 1.5TI aluminum alloy engine independently developed by the company. The maximum power is 113kW/5200rpm, and the maximum torque is 240N·m/1750～3500rpm. The acceleration time from 0 to 100km is only 9.9 seconds. In addition, the Great Wall's 1.5T engine uses an aluminum alloy cylinder block and cylinder head, while supporting a number of lightweight design, making it more weight than the public 1.4T cast iron engine cylinder.
The industry believes that although turbocharged is not a high technology, the difficulty of mastering is not particularly high, but whether or not it can gain the trust of consumers is the most important. Judging from the current situation, compared with the joint venture brand, the self-owned brand turbocharged vehicle still has a price advantage of up to tens of thousands of yuan. Therefore, how to guide more consumers to purchase autonomous turbocharged products will become a government and car company. Common responsibilities and goals.
However, while turbocharger technology has made breakthroughs, China has not made much progress in engine miniaturization. In a country with annual sales of nearly 20 million vehicles, small-displacement models are on the verge of extinction, and models with 1.0-litre or even 1.6-liter models have been forgotten by the market. This is one of the reasons why China’s internal combustion engine emissions exceed the standard and PM2.5 remains high. . “Only the small-sized cars are renewed by consumers, and the engine's small-displacement quantification has become a kind of fashion. The energy-saving and emission-reduction of internal combustion engines can truly become a reality.â€
It is worth noting that in the "Opinions", commercial vehicles, heavy vehicles and diesel vehicles that have been forgotten have all been mentioned. Car analyst Jia Xinguang believes that the government had very strict regulations on the emission standards of passenger cars. For example, the Beijing municipal government implemented the Beijing V standard, but in commercial vehicles and heavy vehicles, the strength of management is not enough. Among the key projects, there are three special upgrades for internal combustion engines for diesel vehicles. "The introduction of the "Opinions" shows that the government has further expanded the scope and intensity of the management of motor vehicle emission standards."
"The current problem facing the automotive industry is that we have not found any energy that can completely replace petroleum. The battery and fuel cell technologies are not yet mature. We will maintain the coexistence of multiple energy sources for a long period of time." Jia Xinguang believes that exploring alternative fuels The application of automotive technology to promote the diversified development of automotive energy not only has important strategic significance, but also has very urgent practical significance. The automobile energy should take a diversified road. "For a long time, traditional cars are still the mainstream of the automotive market. Therefore, the automobile industry should still pay close attention to the traditional car energy-saving and emission reduction work. Electric cars should be decommissioned, but they should not be turned off."
