"We have been working to advance Garrett's electrification capabilities to support the interests of our customers worldwide. As a result, we are pleased to publicly release our first-generation electric turbochargers. The first-generation electric turbochargers can significantly improve The performance and fuel economy of micro-hybrid and plug-in hybrid vehicles can be applied to diesel and gasoline engines. "Garrett President and CEO Rui Bolian said," Electrified engine technology will become the key to addressing industry challenges, not only Increasing energy efficiency and meeting new global emissions regulation goals will also meet consumer demand for better vehicle performance and affordable prices. "
Garrett's electric turbocharger achieves superior performance, fuel economy and lower emissions by integrating state-of-the-art ultra-high-speed motors and power electronics into the turbocharger, while also providing the vehicle's electrical system Provides energy recovery. The electric turbocharger uses a small electric motor on the turbine shaft to accelerate turbocharging. It can provide boost pressure immediately when idling to start, thereby eliminating turbo lag during acceleration, while generating electricity and charging the hybrid battery. Gasoline engines equipped with electric turbochargers can reduce carbon dioxide emissions by up to 15%.
Garrett's new turbocharger boost control software works in conjunction with electric turbocharger hardware to significantly improve turbocharger performance and health, and help optimize energy management for hybrid vehicles. Improve the performance and fuel efficiency of electric turbocharger systems by integrating turbocharging control algorithms into existing electronic control units (ECUs). In addition, Garrett's control software can help optimize turbocharging, torque, efficiency and emissions performance. In addition, this control software can implement pre-diagnosis and intelligent diagnostic functions to detect the health of the entire air circuit in the vehicle, as OEMs focus on all aspects of powertrain design to meet increasingly stringent environmental regulations, including Upcoming Euro 7 emission targets.
Garrett is also exhibiting its comprehensive product range in Frankfurt, including turbochargers, electrification products and connected vehicle software solutions.
The specific products are introduced as follows:
● Gasoline variable-section turbocharger can meet lower emission regulations while achieving lower fuel economy. Variable cross-section turbochargers optimize turbine flow and efficiency by adjusting turbine inlet blades to provide the best fuel economy and transient performance. Our gasoline variable section turbochargers are especially suitable for Miller cycle engines, which can improve fuel economy by 5-10% while achieving lower emissions.

● Hydrogen fuel cell two-stage electric compressor This two-stage electric compressor is used in Honda Clarity fuel cell vehicles. Garrett's two-stage electric compressor has a compact design that solves the previous powertrain size problem, and has the industry's first continuous maximum power density level of 20kW. This technology also has another industry first feature, the use of oil-free foil air bearings. These bearings are cooled by the machine's own compressed air, solving the potential for toxic fuel cells caused by the use of any oil or grease cooling, helping to achieve true zero emissions.
