Garrett Motion showcases Electric Turbocharger at IAA 2019

Garrett Motion Inc., a leading differentiated technology provider in the automotive industry, has developed a new turbocharger boost control software that can significantly enhance turbo performance and health and help unlock optimised energy management in hybrid vehicles.

“We continue to advance our electrification capabilities at Garrett to support the interests of our global customer base. As such, we are excited for the public unveiling of our first-generation E-Turbo, designed to dramatically improve the performance and fuel economy of mild-hybrid and plug-in hybrid powertrains in conjunction with both gasoline and diesel engines,” said Olivier Rabiller, President and Chief Executive Officer for Garrett. “Electrified engine technology will be key in meeting industry challenges for increased energy efficiency and new global regulatory emission targets while still meeting consumer demands for better vehicle performance and affordability.”

Garrett’s E-Turbo delivers superior performance, fuel economy and emissions by integrating ultra-high-speed electric motors and power electronics into the turbocharger, while also providing energy recuperation to the vehicle’s electrical system. The E-Turbo uses a small electric motor on the shaft to spool up the turbo and provide immediate boost from idle, eliminating felt acceleration lag time, and generating electricity and recharging the hybrid battery. E-Turbo’s in gasoline engines can result in up to a 15% reduction in CO2.

In concert with the E-Turbo hardware, Garrett’s new turbocharger boost control software also significantly enhances turbo performance and health as well and helps unlock optimised energy management in hybrid vehicles. Connected software controls support the performance and fuel efficiency potential of E-Turbo systems by integrating boost control algorithms in existing electronic control units (ECUs). Garrett’s software additions contribute to optimised turbo boost, torque, efficiency, and emissions performance. In addition, it also employs prognostic and smart diagnostic functionality to monitor the health status of the entire air loop within the vehicle as OEMs focus on all aspects of powertrain design to meet increasingly more stringent environmental standards, including the upcoming Euro 7 emission targets.

Garrett’s TwoStage Electric Compressor for Hydrogen Fuel Cells is a two-stage electrical compressor used by Honda Motor Company for its hydrogen-powered Clarity Fuel Cell vehicle. Garrett’s TwoStage Electric Compressor eliminates previous powertrain sizing issues with a compact design, and an industry-first continuous maximum power density rating of 20kW. The technology features another industry first with oil-less foil air bearings which are cooled by the machine’s own compressed air eliminating the potential for poisoning the fuel cell with any oils or greases and helping ensure zero emissions.

Garrett will also showcase its connected vehicle software for Integrated Vehicle Health Maintenance (IVHM), which anticipates and directs the fixing of faults before they occur, provides smart diagnostics for faster and more effective maintenance activities, and enhances vehicle or fleet reliability through prognosis-based maintenance.
