来自Cummins Turbo Techn188bet官网ologies的Holset VGT™从1998年为商用车市场开创了可变几何（VG）技术。Holset VGT采用了专利的滑动喷嘴环，提供了宽的流量范围，允许以低发动机速度提高升压压力。VG技术提供最省油的驾驶短路废气再循环（EGR）的方法，用于减少NOx水平。
The Holset VGT is unique because the vanes slide axially so it has fewer moving parts and less wear sites. This improves the durability and reliability of this technology; essential for today’s commercial diesel applications. Cummins Turbo Technologies’ world-class research and development continues to build upon today’s successful Holset VGT by improving total operating costs and fuel efficiency.
The Holset brand has its roots in fixed geometry technology, turbochargers which funnel all the exhaust gas to the turbine to boost engine power. With over 60 years experience of meeting customer power requirements, Cummins Turbo Technologies’ expertise of this technology is tried and tested, and today produces some of the world’s most optimized, efficient and reliable turbochargers.
Although the concept of fixed geometry has been unchanged for decades, Cummins Turbo Technologies has progressively improved performance and reliability, using the same world-class engineering that is used throughout Cummins. As a cost-effective method for boost, Holset fixed geometry turbochargers excel in technical performance, which directly translates into engine fuel economy. These fuel-economy advantages mean that fixed geometry turbochargers are a key customer solution as emissions regulations continue to become more stringent.
