Garrett Authorized Center

Garrett Motion Inc.

An American company primarily involved in engineering, development and manufacturing of turbochargers and related forced induction systems for ground vehicles from small passenger cars to large trucks and industrial equipment and construction machinery.
Garrett technologies and innovations have been used by nearly every major global auto maker, resulting in approximately 100 million vehicles with our products and an average launch rate of 100 new applications annually spanning, gas, diesel, natural gas, electric and fuel cell power trains.

Technologies and Products

Over 60 years of experience

Our highly engineered portfolio is rooted in more than 60-years of pioneering turbocharging systems for gasoline and diesel, but today we go further. Our world-class technical solutions are helping to drive a new era in hybrid electrification and fuel-cell power trains. These innovations enable our customers to set new benchmarks in vehicle performance while addressing evolving fuel efficiency and exhaust emissions regulations. We are also ready for the connected and autonomous vehicle era, with cyber security and prognostic software systems that create a secure and safe operating environment.

High efficiency

Garrett offers gasoline-powered turbochargers called wastegate turbos. They are designed to be smaller than previous turbo generations, have higher fuel efficiency, more torque, and meet emissions standards. Garrett also offers Variable-geometry turbochargers called VNT. They have nine movable vanes, an electrohydraulic actuator, and a proportional solenoid for variable control throughout the engine’s power curve. This means the air passageway of the turbo varies to meet the engine’s needs at different RPMs. Forty million VNT turbochargers have been sold since the 1990s. VNT DutyDrive, previously called Double Axle VNT, uses 12-19 turbine nozzle vanes supported by twin axles for trucks and buses.

Many options

Garrett also offers a diesel engine version of wastegate turbos and VNTs. Dual-Stage turbochargers use two smaller turbochargers either side-by-side (parallel) or in sequence (serial). The first is used at low speeds and a valve opens up the second as engine RPMs increase. The dual stage used in the Audi A6/A7 three litre V6 engine however runs both turbochargers at a lower pressure mode and some use one larger turbo followed by a smaller one. The Dualboost has dual compressors to mimic a twin turbocharger.
