Electric Turbo | A key Technology for EU7
Strong Industry Macros with MHEV set to Grow Fast but need to overlay Regional, National and Local Targets
Air Quality
NOx for Diesel & Particulates for Gasoline
City Tolls, Parking Charges (& ICE Bans)
CO2 (Eu)
2020+ → 95g/km
2025 → 95g/km -15%
2030 → 95g/km -30%
Eu7 (2023+) | Gasoline example
No Scavenging → Risk to LET
Lambda 1 → Risk to Rated Power
RDE Full → Emission from t=0
Need to achieve better Fuel Economy and Eu7 will be a real challenge for both Diesel & Gasoline
Diesel
- Garrett remains committed to Diesel.
- Mono, TwoStage & Electrified Solutions available for Eu6d (CF1,0+0,5)
Gasoline
- MGT Gen 3 Launched in multiple applications in 2017
- New ECO Gas engines are emerging eg. Miller / VNT is one solution in A, B & C segments
- Cooler EGR, Water Injection & VCR also emerging. MGT Gen 4 is ready.
- LEAN is posing new transient challenges as the next step in Gasoline Fuel Economy
Hybridisation
- eCharger provides ultimate Performance and Fun to Drive (dependant on SOC)
- electric Turbo excellent transient enabler (Monostage) and high potential as LP Stage (TwoStage)
- electric Turbo with Advance Compressor competes with Turbo/eCharger system & Recuperates
