INCREASED POWER & EFFICIENCY
Electric Turbo Innovation
Electrified Turbos show exciting potential and equal applicability in both light & commercial vehicles, in all fuels such as gasoline, diesel and natural gas (CNG)

E-Turbo | A Key Technology for EU7
Garrett has created an E-Turbo demonstration vehicle that is a successful representation of how an electrified boosting solution can increase engine power and torque while allowing the engine to operate at Lambda 1, providing energy recuperation to the vehicle’s electrical system.
Electrifying a turbocharger removes the constraint of needing a small turbine with excellent efficiency to drive the compressor at low flow rates. Instead, it allows us to right size the turbine for Lambda 1 rated power.
Lambda 1 (or stoichiometric air/fuel ratio) is a key part of future Legislation.
Strong industry macros indicate that all forms of hybridization set to grow fast (MHEV, HEV, PHEV)
The technologies will be used to meet regional, national and local fuel economy and air quality targets
CO2 -15% by 2025, -37,5% by 2030 (vs 2020)
RDE – City, Extra Urban & Highway
City Access – Tolls & Parking Charges
Gasoline – Particulates & Lambda 1
Diesel – NOx & NH3
Powertrains must be hybridized to meet the fuel economy and emission targets of EU7
E-Turbo provides an integrated, compact and balanced solution that delivers the additional functionality of Energy Recuperation (Efficient energy Management / Positive effect on state of charge SOC). Any penalty in inertia can therefore be more than compensated for by an electric motor and the addition of a wide-range Compressor to improve low-end response and extend high-end performance simultaneously.
