Engine performance and efficiency while reducing overall size
Variable Geometry Turbos for Diesel Key Features
A variable geometry turbo for a diesel engine controls engine exhaust flow through the turbine wheel using a row of vanes. These vanes open and close to match the engine’s exact boost requirements.
At LOW SPEEDS, the vanes close, which:
- Restricts exhaust airflow through the turbine
- Increases turbine power
- Increases boost pressure
At HIGH SPEEDS, the vanes open, which:
- Maximizes exhaust gas flow
- Avoids turbo over-speed
- Maintains required boost pressure
Our PATENTED PRESSURE BALANCE directs exhaust gas to both sides of the vanes, which:
- Prevents excess axle loading
- Reduces friction and wear
- Improves Boost control
Two-Stage Parallel Turbochargers for Diesel Engines
In our Two-Stage parallel systems, two turbos work in sequence, delivering significant gains in power and torque in engines typically 2.0L or bigger.
Two-Stage Serial Turbochargers for Diesel Engines
Garrett’s Two-Stage serial turbo for diesel compounds the benefits of turbocharging by using two turbos in a series arrangement. This helps improve transient performance, offers better low-speed torque and optimizes fuel efficiency in passenger and commercial vehicle applications. Auto manufacturers can use this technology to either downsize engines or increase performance.
Our variable geometry turbos for diesel engines are available in a full range of sizes. Mono-turbo setups work best with 1.3L to 4.5L diesel engines in passenger cars.
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. However, further enhancements can be realized using our connected vehicle solutions, including Integrated Vehicle Health Management and advanced powertrain control. We also offer cybersecurity software and a range of electronic boosting products.
Ultra-Efficient Clean Diesel Platforms Can Benefit Greatly from Garrett’s Downsized, High-Temperature VNT Boosting Technology
Garrett’s sixth generation variable geometry turbo architecture (VNT) is helping auto manufacturers harness the performance potential of higher temperature diesel powertrains.
Garrett Motion Showcased the Electric Turbocharger for the First Time at IAA 2019
The growing trends toward hybridization open up possibilities to transfer electric boosting technology from racetrack to road. Garrett is pioneering E-Turbo technology to deliver superior performance, fuel economy and emissions, by integrating state-of-the-art, ultra-high-speed electric motors and power electronics into its turbocharger product families.
Electrified Turbos (E-Turbos) show exciting potential and equal applicability in both light & commercial vehicles, in all fuels such as gasoline, diesel and natural gas (CNG).
