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 offers a wide flow range that allows for higher boost pressures at low engine speeds. VG technology provides the most fuel-efficient means of driving short-route Exhaust Gas Recirculation (EGR), which is used to reduce NOx levels. The Holset VGT™ is in wide use across Light Duty applications through to Mid Range and Heavy Duty Applications.
