Wastegate Turbochargers for Gasoline Engines

Our Wastegate Turbochargers for gasoline engines serve the full spectrum from sub-1 liter economy 3 cylinders to premium and high-performance V8s and V12s, with availability in mono-scroll and twin-scroll turbine configurations

 

Optimize engine control, fuel efficiency & performance

Garrett – Advancing Motion wastegate turbos for gas engines use advanced technology and materials to achieve best-in-class efficiency, performance, and engine control.

Engine Range

Achieving peak performance is essential for gasoline engines amid tightening fuel efficiency and emissions standards. To enable smaller, lighter and more efficient engines, Garrett’s wastegate turbochargers for gasoline engines use advanced aerodynamics, materials and bearing systems that maximize efficiency, power density at optimized cost. Our wastegate turbos for gas engines are available in several mono-scroll and twin-scroll configurations, spanning <1L displacement to more powerful options up to 3L per turbo.

Wastegate Turbo Key Features

We have enhanced turbocharger performance through optimized aerodynamics. Our gasoline wastegate turbos feature turbines and compressors feature wheels with radial, mixed, low- and high-flow capabilities. The new generation of wheels, as well as compact volutes, satisfy the distinct requirements of both low- and high-power engines.

Many modern gas engines use wastegate turbochargers, which control boost levels through electric-actuated bypass valves. Operating at higher temperatures than diesel turbos, they are often water-cooled and constructed using high-temperature aerospace-capable alloys.
Other key features include:

  • Unique semi-floating Bearing that is 30 percent smaller and reduces friction losses by 20 percent.  Also available with ball-bearing option.
  • Redesigned recirculation valve that minimizes surge
  • Electric actuator option for accurate control and faster response
