The Ministry of Industry and Information Technology takes the lead in the era of turbocharged popularization

Recently, the Ministry of Industry and Information Technology has formulated the "12th Five-Year Plan" for industrial energy conservation. Among them, the internal combustion engine system energy-saving project mentioned the use of advanced internal combustion engine manufacturing processes and materials, optimization of the matching technology of the complete machine and supporting machinery, vigorously promoted exhaust gas turbocharging technology, and focused on supporting electronically controlled high-pressure fuel injection systems, high-efficiency superchargers and key The development of parts and components industry. By 2015, the fuel consumption rate of internal combustion engine products will be reduced by 10% compared with 2010, and energy-saving internal combustion engine products put on the market will account for 20% of the market.

At present, many manufacturers have already used turbocharging technology. Volkswagen is the first car company to market small-displacement turbocharged engines. Its TSI+DSG portfolio has been sought after by the market and its products have been in short supply. BYD, Great Wall, Brilliance, SAIC, Chery and other independent brands have also introduced turbocharged engines, and Chery is developing 0.8T turbocharged engines. General Motors is developing a 3.6-liter twin turbocharged engine. Even the BMW brand, which has always insisted on naturally aspirating engines, is also developing twin-turbocharged engines.

Turbocharged engines rely on turbochargers to increase the amount of engine air intake, thereby increasing the engine's output power. The biggest advantage is that it does not increase the displacement, significantly increase the engine power and torque, improve fuel economy and reduce emissions. The data shows that the use of turbocharging technology can help gasoline and diesel vehicles to save up to 20% and 40%, respectively, without degrading performance. At the same time, significant cost savings can be achieved compared to hybrid and electric vehicles.

In previous years, the state introduced a number of policies and allocated a large amount of funds to encourage the development of electric vehicles. However, there were few sales in the market. Later, the national adjustment policy paid equal attention to energy-saving cars and new energy vehicles. As long as it helps reduce fuel consumption and emissions, various technologies will be allowed and encouraged. Wang Binggang, a special expert of the major science and technology project for the “Energy Conservation and New Energy Vehicles” program of the Ministry of Science and Technology of China (863), has said that the state will focus on the development of four technologies, one of which is the advanced power system and vehicle technology, such as advanced engines and gearboxes. . Small-displacement turbocharged engines, while achieving energy savings, have reduced emissions and fuel consumption and are undoubtedly the most suitable.

Some foreign companies expect that the global turbocharged engine market will double in sales in the next five years. In 2009, global sales of turbocharged engines totaled 17 million units. In 2015, this figure will reach 35 million units. It is estimated that by 2015, the share of turbocharged engines in the Chinese market will increase from the current 10% to 20%.

The "12th Five-Year Plan" of the Industrial Energy Conservation also mentioned that high-pressure fuel injection, booster, exhaust after-treatment, high-efficiency filtration, low friction, and high sealing technology will be promoted to improve the overall efficiency of the internal combustion engine and reduce the fuel consumption of the internal combustion engine. . It is expected that with the support of national policies, the future of small-displacement turbocharged engine models will become a trend.
