Lower costs & Higher Efficiency through innovative design
Small Wastegate Turbochargers for Diesel Engines
Garrett’s small wastegate turbos for diesel engines offer advanced performance, fuel efficiency and low emissions in a compact design.
Our small wastegate turbos for diesel engines are available for engines ranging from 0.8L to 3L, corresponding to power ratings ranging from 30kW to 120kW.
Small Wastegate Turbos for Diesel Key Features
Wastegate turbos control engine boost levels by coordinating the actuator and bypass valves. At low speeds, the bypass valve closes to ensure maximum exhaust flow to the turbine and fast turbo response at ignition. At high speeds, the bypass valve opens, limiting the exhaust gas entering the turbine and controlling boosted air supply.
Other notable features include:
- Aerodynamic design focused on low-end efficiency
- Z-Ultra bearings that improve low-end torque and transient response
- Enhanced oil sealing and blow-by levels
- Optimized seal and piston ring designs
All of our small wastegate turbos for diesel engines are designed to meet ongoing rightsizing requirements.

Garrett’s variable geometry VNT technology has been matched to more than 70 million diesel engines in the last three decades. The turbo’s advanced design helps manufacturers boost car and light commercial vehicle engine performance, increasing fuel efficiency, reducing emissions, enhancing driveability and improving packaging flexibility.
Our Two Stage parallel turbo for diesel engines was an industry first when we released it in 2006. Since then, it’s increasingly in-demand among auto manufacturers seeking enhanced performance, fuel efficiency and emissions control.
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.
Garrett’s small wastegate turbos for diesel engines are just one way we’re improving automobiles. We also offer a variety of connected solutions, including Integrated Vehicle Health Management, advanced powertrain controls and cybersecurity software. In addition, our electric turbochargers and boosting technology helps control emissions without reducing performance.
Garrett Motion Showcased the Electric Turbocharger for first time at IAA 2019
The growing trends toward hybridization opens 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 highspeed electric motors and power electronics into it’s 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).
