In 2015, the rate of diesel fuel consumption will be reduced by 10%

A few years ago, the state has adopted a number of policies to encourage the development of electric vehicles play a large sum of money, but the market sales scanty. Later, the national adjustment policy, energy saving vehicles and new energy vehicles of equal importance, as long as it is conducive to reducing fuel consumption and emissions, all kinds of technologies will be allowed and encouraged. The Ministry of science and Technology Plan 863 "energy-saving and new energy vehicles of major scientific and technological special expert Wang Binggang said that the country will focus on the development of four aspects of the technology, which is one of the advanced power systems and vehicle technology, such as advanced engine and gearbox. The small displacement turbocharged engine can meet the requirement of reducing energy consumption and emissions while achieving energy saving.

At present, many manufacturers have been using turbo technology. Volkswagen is the first to small displacement turbocharged engine market car prices, and its launch of the TSI+DSG portfolio sought after by the market, the product has been in short supply. BYD, the Great Wall, brilliance, SAIC, Chery and other independent brands have launched a turbocharged engine, Chery is developing 0.8T turbocharged engine. General Motors is developing a 3.6L twin turbo engine, and even the BMW brand, which has consistently adhered to the naturally aspirated engine, is also developing a twin turbo engine.

"Energy saving" 12th Five-Year "plan" also mentioned, will promote the technology of high pressure fuel injection, turbocharging exhaust, postprocessing and efficient filtration, low friction and high sealing, improve the overall efficiency of the internal combustion engine, reduce engine fuel consumption. Expected to have national policy support, the future of small displacement turbocharged engine models will become a trend.

Foreign companies predict that the world's turbocharged engine market will double sales in the next 5 years. In 2009, the world's total sales of turbocharged engines totaled 17 million units, and this figure will reach 35 million units in 2015. By 2015, China's market share of turbocharged engines will rise from nearly 10% to 20%.

A turbocharged engine relies on a turbocharger to increase the intake of an engine, thereby increasing engine output. Its biggest advantage is not to increase the displacement, greatly enhance the power and torque of the engine, improve fuel economy and reduce exhaust emissions. Data show that the use of turbocharged technology can help gasoline and diesel vehicles without reducing performance, respectively, fuel saving of 20% and 40%. At the same time, compared to hybrid vehicles and electric vehicles, but also to achieve substantial cost savings.

Recently, the Ministry of industry and information technology formulated the plan for industrial energy saving in 12th Five-Year. The energy-saving project of internal combustion engine system that used engine manufacturing technology and advanced materials, matching technology to optimize the machine and auxiliary machinery, vigorously promote the exhaust gas turbocharger technology, focusing on the development of the electronic controlled high-pressure diesel fuel injection system, efficient supercharger and key spare parts industry. By 2015, the fuel consumption rate of diesel engine products was 10% lower than that of 2010, and the energy saving IC products on the market accounted for 20% of the total market share.
