CO2 Downsizing Exhaust MPG 
Green Car Congress
JULY 14, 2016
The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. mpg (10.99 A significant fraction of the GDI PM 2.5 The extent of fuel-air mixing can be affected by injection system design.

Given the properties of the fuel blend, improved fuel efficiencies can be generated by several approaches, including downsizing/downspeeding; increased compression ratio; reduced enrichment; and the leveraging of improved efficiency at part load. Downsizing/downspeeding. Reduced enrichment. Anderson, J. and Stein, R.,

Power for the battery and VTES electric supercharger is not only supplied by the SpeedStart ISG but also the TIGERS exhaust driven turbo-generator. Conversely, short bursts of power can also be absorbed by the SpeedStart generator to recharge the battery during vehicle decelerations. liters capacity.

Focused on meeting a growing customer demand for ‘downsized’ engines offering strong power with reduced fuel consumption and CO2 emissions, the new gasoline and diesel powertrains are being progressively introduced across the Opel product range. The engine retains the proven concept of a turbine-integrated exhaust manifold.

The CAFE program promised to double fuel economy by 2025 , but from 2012 to 2019, the real-world MPG of new vehicles improved just 7% , and annual gasoline consumption increased from 3.2 MPG as 14 out of 20 automakers failed to meet their standards. billion barrels. In 2019, fuel economy actually worsened, dropping slightly from 25.1
