HOLSET.®Turbochargers and Air Handling学到更多
Commercial diesel engines require advanced technologies that deliver efficiency and meet strict emissions requirements. Our fixed, wastegate, variable, two-stage, turbo-compounding and waste heat expander technologies were specifically developed to deliver higher efficiency and lower cost.
Today, Cummins Turbo Technologies engineers are actively developing state of the art solutions for the next generation, including assisted turbocharging, new bearing systems and enhanced compressor stage performance.
The Holset®品牌源于固定几何技术,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 is tried and tested, and produces some of the world’s most optimized, efficient and reliable turbochargers.学到更多
Variable Geometry Turbochargers
The Holset®VGT™ from Cummins Turbo Technologies pioneered Variable Geometry (VG) technology for the commercial vehicle market in 1998. Featuring a patented sliding nozzle ring, the Holset®VGT™提供宽的流量范围，可在低发动机速度下进行更高的升压压力。VG技术提供最省油的驾驶短路排气再循环（EGR）的方法，用于减少NOx水平。学到更多
Wastegate technology helps to prevent turbocharger over-speeding, as well as engine overboost. The well-engineered Holset®wastegate turbochargers employ the same industry-leading design techniques used throughout Cummins. Wastegate turbochargers improve upon fixed geometry units with an overall 3% increase in efficiency, and they can be optimized for various aftertreatment systems.学到更多
