What is an Electric Turbocharger? Exploring the Power and Efficiency of Garrett’s E-Turbo

In the relentless pursuit of advanced, eco-conscious automotive technologies, Garrett Motion stands at the vanguard with its E-Turbo technology. This award-winning innovation, first launched in 2021 on a Mercedes-AMG passenger vehicle, is a testament to our commitment to revolutionizing the automotive landscape.

The electric turbocharger, or E-Turbo, isn’t just an enhancement to traditional turbocharging systems; it’s a complete reimagining, offering unparalleled benefits in efficiency and performance for hybrid vehicles. Let’s delve into the mechanics, advantages, and environmental impact of Garrett’s E-Turbo, setting new standards for sustainable high performance.

How Garrett’s E-Turbo Works:

Unlike traditional systems powered by exhaust gases, our E-Turbo harnesses an electric motor to propel the compressor. This innovative approach ensures optimized engine efficiency and performance across all RPMs. Comprising an electric motor, compressor, turbine and advanced power electronics, Garrett’s E-Turbo delivers a seamless, efficient air supply to the combustion chamber, markedly increasing power output while enhancing fuel efficiency.

The E-Turbo is transformative because it enables higher power rating for engines by de-constraining turbo design from low engine speed requirements. The result is an architecture that enables the turbine to be sized to deliver performance without compromise at high speed, while the onboard electric motor provides instantaneous boost via the compressor at lower engine speed, where there is less available exhaust gas energy.

The Magic Behind the E-Turbo:

  • Electric Motor: Powers the compressor to provide instant air pressure, ensuring immediate response and eliminating lag.
  • Compressor: Forces more air into the combustion chamber, significantly boosting engine power.
  • Turbine: Uses the exhaust gas to deliver boost, just like a regular turbo, and recuperates energy at high engine RPM
  • Power Electronics: Controls the electric motor, guaranteeing the E-Turbo operates at peak efficiency.

The Unmatched Benefits of Garrett’s E-Turbo Technology:

Garrett’s E-Turbo technology reshapes what we expect from turbocharged vehicles, offering:

  • Instant Boost Response: Say goodbye to turbo lag. Our E-Turbo delivers instantaneous power, enhancing the driving experience with immediate throttle response.
  • Superior Fuel Efficiency: By optimizing the air-fuel mixture at all RPM, Garrett’s E-Turbo ensures engines run more efficiently, burning less fuel without compromising on performance.
  • Compact, Lightweight Design: Our E-Turbo’s sleek, lightweight construction not only saves space but also contributes to overall vehicle efficiency, supporting enhanced fuel economy and reduced emissions.
  • Energy recuperation: The electric motor can recuperate energy from the exhaust gas, replenishing the battery.
  • Customizable Performance: Our E-Turbo technology allows for unprecedented control over boost levels and engine performance, catering to diverse driving preferences and conditions.

Driving Toward Cleaner Emissions with Garrett’s E-Turbo:

In the face of growing environmental concerns, Garrett’s E-Turbo emerges as a key player in reducing emissions and advancing engine efficiency:

  • Reduced Carbon Footprint: By improving combustion efficiency, Garrett’s E-Turbo significantly lowers harmful emissions, contributing to a cleaner environment.
  • Engine Downsizing Potential: Our E-Turbo supports the trend towards smaller, more efficient engines that match the power of larger units, further decreasing fuel consumption and emissions.
  • Bridging to Electrification: Garrett’s E-Turbo technology represents a critical step towards vehicle electrification, for example by enabling latest generation hybrid vehicles to convert excess exhaust gas energy into electrical power to optimize system performance.
