For a car with a 1.6-liter engine, using a turbocharger can cut CO2 emissions by 1.4 metric tons; the CO2 saved by one million turbocharged cars is equal to the amount absorbed by 2.6 million mu of forest. As new-energy vehicles become a trend and receive strong support from national policy, the turbocharger has also become a bellwether for energy saving and emission reduction in the automotive industry. A company in Fengcheng, Liaoning, began introducing turbocharger technology in the early 1980s; it can be said to be the first company in China to work with this technology and has remained among the domestic leaders ever since. Its turbocharger production and sales now rank third in the industry in China and first among domestic brands. Its share of the domestic market is above 22%, new products have accounted for more than 50% of output value for five consecutive years, and it follows closely behind the major international turbocharger manufacturers.
Ding Zhijian, deputy director of the company's turbocharger research institute, explained that a turbocharger uses exhaust gas to drive a turbine, which forces more air into the engine so that the fuel burns completely, thereby reducing fuel consumption. He said that adding a turbocharger can raise a car's power by 20%–50% and in turn cut fuel consumption by 15%–40%.
