The fundamental characteristics shared by all TDI engines are high-pressure fuel injection and variable turbine geometry for excellent cylinder charging and an efficient combustion process. 所有TDI发动机的基本特征是高压燃油喷射,以及为优秀的汽缸做功和有效地燃烧过程的可变涡轮几何(VTG)曲线。
It is possible that turbochargers on which the ball heads on the adjustment mechanism for variable turbine geometry can become corroded were installed in some vehicles. 有些车辆上安装的涡轮增压器的可变涡轮几何(VTG)特性调节机构上的球头可能受到了腐蚀。
