In the photo above, the popular BorgWarner S Sign up for more restomod content to add horsepower to your inbox. VGT, Brought to the Masses By no means did the diesel truck segment introduce the world to variable geometry turbo VGT technology, but when it debuted in aboard the best-selling Ford Super Duty, it was brought to the masses.
The Infamous Unison Ring With rust buildup and soot and carbon present, it causes the unison ring to bind, which in effect means the vanes can no longer route exhaust gasses appropriately.
Mechanically Actuated, Electronically Controlled While vacuum actuation is one method of variable geometry functionality, all turbochargers used in the pickup segment are electronically controlled, mechanically actuated units. Use Your Exhaust Brake The best thing you can do to avoid soot, carbon and rust building up on the exhaust side of the turbo especially on the 6. It's In Their Nature By nature, variable geometry turbos create more drive pressure exhaust side than a comparably sized fixed geometry unit.
High Drive Pressures Contribute to Blown Head Gaskets While excessive boost levels are the primary contributor to head gasket failure, extreme drive pressure can play a supporting role.

Yes, I would like to receive communications including news, special offers, and product information about Nitto Tire products. This cut-through diagram shows the exhaust gas flow when the variable turbine vanes are fully open.
The high exhaust flow at high engine speeds are fully directed onto the turbine blades by the variable vanes. Variable Turbine Geometry has been used extensively in turbodiesel engines since the s, but it has never been on a production petrol turbocharged car before until the new Type Porsche Turbo. This is because petrol engine exhaust gases are alot hotter than diesel engine exhaust gas, so generally the material used to make VTG turbos could not stand this heat.
The Turbo uses a BorgWarner VTG turbocharger which uses special materials derived from aerospace technology, hence solving the temperature problem. Reduced Emissions by enabling exhaust gas recirculation EGR. Variable Geometry Turbos for Diesel and Connected Vehicle Solutions Our variable geometry turbocharger technology for diesel engines helps improve engine performance and efficiency across the spectrum.
Garrett Motion Showcased the Electric Turbocharger for the First Time at IAA The growing trends toward hybridization open up possibilities to transfer electric boosting technology from racetrack to road.
