Following the subsidy for energy-saving and environmental protection of passenger vehicles, the commercial vehicle sector will also implement financial subsidies for energy-saving and environmental protection products. The Chinese government’s website recently announced the “Opinions of the General Office of the State Council on Strengthening Energy-saving and Emission Reduction of the Internal-combustion Engine Industryâ€, which will improve the energy-saving efficiency of gasoline and diesel engines as an important measure to improve air quality. By 2015, the national energy-saving internal combustion engine products will account for the total inventory. 60%.
With the scale of new car sales ranking first in the world, China has become the world's largest producer and consumer of internal combustion engines. In 2011, the energy consumption of internal combustion engines of automobiles and ships accounted for 59.27% ​​of China's total oil consumption in the year, which is equivalent to the total amount of oil imported throughout the year. However, compared with the international advanced level, China's internal combustion engine products still have a large gap in energy conservation and environmental protection indicators. The reporter was informed that in the European market, the market share of higher-efficiency turbocharged models has exceeded 50%, while the domestic market share of energy-saving and environmentally friendly models is still very low, especially in the field of commercial vehicles where pollutant emissions are much higher than that of passenger vehicles. .
According to the newly published opinions on the energy-saving and emission reduction of the internal combustion engine industry, the fuel consumption rate of the internal combustion engine in 2015 must be reduced by 6% to 10% compared with 2010, achieving a saving of 20 million tons of commercial fuel, a reduction in carbon dioxide emissions of 62 million tons, and a reduction in nitrogen oxide emissions by 10%. Using alternative fuels to save 15 million tons of commodity fuel.
For energy-saving and emission-reduction purposes, China will encourage small-displacement gasoline engines with displacements below 2.0 liters, especially below 1.6 liters, to adopt supercharged and direct injection technologies to promote lightweight technologies. By 2015, 30% to 40% of newly-produced gasoline gasoline engine products will use in-cylinder direct-injection fuel systems, and the fuel consumption rate will be 8% to 10% lower than in 2010. The newly-produced vehicle diesel engines all use high-pressure fuel injection systems, and the fuel consumption rate is reduced by 5% to 8% compared with 2010.
At the same time, on the basis of the policy of subsidy for energy-saving passenger vehicles and financial subsidies for agricultural machinery industries, government departments will study and formulate financial support policies for the promotion of energy-saving and environment-friendly commercial vehicles to promote the development of high-efficiency internal combustion engines; Internal-combustion engine products related to tax relief policies; to improve the retirement subsidies for old agricultural machinery, and to promote energy-saving and emission reduction of agricultural machinery.
Actively developing diesel and natural gas dual-fuel internal combustion engines and biodiesel internal combustion engines and piloting the application of gasoline and methanol dual-fuel internal combustion engines are also important ways to save oil consumption and reduce atmospheric pollution. By 2015, through the promotion and application of natural gas single fuel, dual fuel and biodiesel internal combustion engines, the country will achieve 10 million tons of alternative commodity fuel; through the promotion of the application of methanol fuel internal combustion engines, 5 million tons of alternative fuel oil will be realized.
Analysts from the automotive industry have commented that this opinion was released on the one hand because of persistent public haze in northern China that caused public concern and on the other hand, it was also driven by the energy shortage crisis brought about by the automobile society. At the global level, the development of new energy vehicles such as electric vehicles is not satisfactory. Therefore, a more realistic path to save fuel consumption is the upgrading of traditional internal combustion engine technology.

Slower oil upgrades or drag on internal combustion engine emissions
The grand plan of energy-saving and emission-reduction of internal-combustion engines has caused auto companies to face the problem of inadequate engine key technology reserves. What consumers are more worried about is that the upgrading of oil products will affect the performance of automobiles.
At present, fuel standards vary widely across China: In gasoline, Beijing adopts the Beijing V standard, and more than a dozen provinces and cities in Shanghai implement the national IV standard. Other regions still implement the national III standard. Regarding diesel, except for a few regions that implement State III standards, most are still using country standards. If the quality of the oil is too low, the emission reduction effect of engine technology upgrades will be difficult to achieve, and consumers will even be exposed to increased engine maintenance costs due to too many fuel impurities.
It is understood that every upgrade of the Beijing Automotive Emission Standard, the corresponding standard of high-quality oil supply can be put on the market in advance to achieve a smooth replacement. However, looking across the country, upgrading of oil products has become a major obstacle to the implementation of new standards for vehicle emissions. Taking the IV emission standard of heavy-duty diesel vehicles as an example, the national environmental protection agency originally planned to implement it from January 1, 2010, but was forced to postpone it twice because of the delay in supplying the National IV diesel. The current national standard for heavy-duty diesel vehicles IV The latest timetable for implementation is July 1 this year.
In China, diesel consumption accounts for about 70% of the total amount of gasoline and diesel, and huge investment in oil upgrades has become the biggest resistance to the improvement of diesel quality. The main service logistics and diesel production areas of diesel vehicles are the high price of high-quality diesel oil, which will inevitably push up the sensitive CPI data.
Earlier this month, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) and the National Standards Committee issued the National Standard for Vehicle Diesel (IV). The transition period lasted until December 31, 2014, which stipulated that the sulfur content of diesel fuel for Phase IV vehicles should not exceed 50ppm ( 1ppm is one millionth). According to the plan, by the end of June 2013, China will release the national V-phase diesel standard for vehicles. Before the end of 2013, it will release the V-phase gasoline standard for vehicles with sulfur content not exceeding 10ppm. The transition period will be until the end of 2017.
The basic Aluminium Die Casting process consists of injecting molten metal under high pressure into a steel mold called a die.
Advantages of Aluminium Pressure Aluminium Die Casting China :
0. the density of adc12 and aluminium is 2.75g/cm^3
1. Aluminium Die Casting Lower costs compared to other processes.
2. Economical – typically production of any number of components from thousands to millions before requiring replacement is possible.
3. Castings with close dimensional control and good surface finish
4. Castings with thin walls, and therefore are lighter in weight
