Small Wastegate Turbochargers for Diesel Engines

Our latest small wastegate turbos, with improved aerodynamics, provide a cost-effective route to fuel efficiency and emissions control without compromising performance. The compact design focuses on low-end torque and transient response and, with its lighter weight, offers packaging flexibility valued by automakers.

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.

Engine Range

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.
