Where the internal combustion engine system energy saving projects mentioned, the use of advanced manufacturing technology and materials combustion engine, optimizing and supporting the whole machinery of matching technology to promote exhaust turbocharger technology, focusing on high-pressure electronically controlled fuel injection system,passat 1.8 turbo high efficiency turbocharger and key development of parts industry. By 2015, the internal combustion engine to reduce fuel consumption goods 10% more than in 2010, the market share of energy-efficient internal combustion engine products market holdings of 20%.

Currently, many manufacturers have used turbocharging technology. Volkswagen was the first to market small-displacement turbocharged engine of the car companies, the introduction of TSI DSG combination sought after by the market, the product has been in short supply. BYD, Great Wall, Brilliance, SAIC, Chery and other independent brands have also introduced a turbocharged engine, Chery is developing a 0.8T turbocharged engine.vw passat turbo General Motors is developing a 3.6L twin-turbo engine, and even has always insisted naturally aspirated engine of the BMW brand, is also developing twin-turbo engine.

Turbocharged engines rely on an increase in engine turbocharger intake air, thereby increasing engine power output. Its biggest advantage is not to increase emissions, significantly increasing engine power and torque, improve fuel economy and reduce emissions. Data show that the use of turbo technology can help gasoline and diesel vehicles in fuel economy without compromising performance up to 20% and 40% respectively. Meanwhile, compared to hybrid vehicles and electric vehicles, but also to achieve substantial cost savings.

A few years ago, the state introduced a number of policies, large sums of money to encourage the development of electric cars, but few market sales. Later, the national adjustment policies on energy efficient cars and new energy vehicles equal importance, as long as help to reduce fuel consumption and emissions, a variety of techniques will be given permission and encouragement. 863 Plan "energy-saving and new energy vehicles," Wang Binggang major science and technology projects Distinguished experts have said the country will focus on four areas of technology development, one of which is an advanced powertrain and vehicle technologies, audi a4 turbocharger such as advanced engine and gearbox . Small-displacement turbocharged engine in achieving energy efficiency, while reducing emissions and fuel consumption, is undoubtedly the most to meet the requirements.

There are foreign company expects the global turbocharged engine market will achieve sales double in the next five years. In 2009, worldwide sales totaled turbocharged engine 17 million units in 2015, this figure will reach 35 million units. By 2015, the market share of the turbocharged engine from the current nearly 10% rise to 20%.

"Industrial energy" Twelfth Five-Year "plan" also mentioned that the promotion of high-pressure fuel injection, turbocharger, exhaust after treatment, filtration efficiency, low friction and high sealing technology, improve the overall efficiency of the internal combustion engine, the internal combustion engine to reduce fuel consumption . Expected to have a national policy support, the future of small-displacement turbocharged engine models will become a trend.
