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. The extent of fuel-air mixing can be affected by injection system design. They assumed a baseline fuel economy of 21.4

The Automaker Rankings report examines the emissions of both global warming and smog-forming pollution from of the automakers. This report marks the first time another company has bested Honda, which came in second this year but has earned every “Greenest Automaker” designation from UCS since 1998. Source: UCS.

New substrates are designed with thinner walls or higher porosity, which allows the coating of better catalysts without sacrificing durability. This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. —MECA Executive Director, Rasto Brezny.

By rightsizing engines with available technologies, automakers are able to continue applying the benefits of smaller turbocharged engines while fine-tuning powertrain systems to further optimize fuel economy, emissions and performance. E-boosting products can significantly improve engine responsiveness and also provide better fuel economy.

Pollutant emissions are likewise reduced through combustion control. Applied to a turbocharged, downsized engine, MultiAir can contribute to up to a 25% reduction in fuel consumption over conventional naturally aspirated engines with the same performance, according to Fiat.

However, prior to the remarks on climate change and the regulatory response, he spent a few minutes discussing the efforts on urban pollution—e.g., What more is need to end urban pollution, something we’ve been spending over 30 years working on? smog and particulates. We heard a little bit from Tom Cackette yesterday about LEV III.I

The design brief for the new-generation PureTech engines called for a clean break in powertrain development. To achieve these results, PureTech development called for a number of changes, chief among which were: Downsizing. Reduced weight and more compact design. l/100 km (51.1 Three cylinders. Reduced internal friction.
