The variable geometry turbocharger (VGT) employs a variable nozzle design that controls nozzles mounted on the outside of each blade to adjust the speed and volume of exhaust gas flow, ensuring that it consistently strikes the turbine blades at the optimal speed and in the optimal direction. The result is reduced turbo-lag for quick response and torquey low-end performance combined with consistently efficient boost pressure that delivers the power needed for spirited performance at high engine speeds.
The BT-50 is the world’s first pickup truck to adopt a VGT design that secures both sides of the nozzle for improved durability and resistance to friction.
Clearance control pins maintain the right amount of side clearance required by the nozzles to move, even at high
operating temperatures, which maintains a high level of
flow efficiency that also improves durability and reliability.
A compact turbine housing design and turbine with low inertial moment improve VGT control response.
