As environmental protection has become a socially important issue, our government has realized the harmfulness of automobile exhaust to air pollution. Not long ago, the State Environmental Protection Administration released the “Notice on Implementing the Second Phase of State Motor Vehicle Emission Standards” stipulating that “the second phase of emission standards for heavy-duty diesel vehicles and heavy-duty gasoline vehicles” will be implemented in China starting September 1, 2003. This marks our country in the country started to implement the equivalent of Euro Ⅱ standard vehicle emission regulations. Beijing also promised to meet Euro III emission standards by the 2008 Olympic Games. Increasingly stringent emission standards for diesel engines put forward higher and higher technical requirements. Because of this, a product called an “exhaust gas turbocharger”
