New Federal-Mogul Powertrain high thermal conductivity seats and guides keep engine valves cooler; improved combustion, lower emissions

Green Car Congress

Federal-Mogul Powertrain will debut new materials for valve seats and guides with improved thermal conductivity at the 2017 IAA Show in Frankfurt, Germany next month. If late ignition timing is used to reduce knock and enrichment is protecting components from critical temperatures, CO 2 emissions are increased.

Ford study suggests GDI engines can meet coming California and US PM emissions standards over 150k miles; more work to be done

Green Car Congress

PM mass emissions rates for the FTP and US06 drive cycles as function of vehicle mileage. The EU has already set a standard for 6 × 10 12 number/km limits between 2014 and 2017, tightening to 6 × 10 11 number/km.). These efforts are yielding reductions in PM emissions, but this is still a work in progress. Click to enlarge.

Bosch leading Direct4Gas consortium to develop direct injection for monovalent natural gas engines

Green Car Congress

The problem with this configuration is that neither the combustion process nor the values for efficiency and emissions can be optimized. The very high octane rating and resulting high resistance to knock is promising for small, supercharged, downsized SI engines. The project started in January 2015 and will run until the end of 2017.

Bosch sees future requiring multiple powertrain technologies; the larger the vehicle, the more the electrification

Green Car Congress

While policies worldwide are tightening emissions and fuel economy standards, the strictest standard of all is expected in Europe in 2020, Bohr said—average fleet CO 2 emissions of 95 grams per kilometer. This will be done with a broad range of efficiency-enhancing technologies, including the turbocharging of downsized engines.

Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges

Green Car Congress

This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today. Regional highlights include: In North America, more engine downsizing is expected. liters and 1.7 The current average engine size is a 3.0-liter
