Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

The researchers assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). liter downsized turbocharged centrally-mounted direct injection engine.

Advanced Turbocharged, Direct Injected Gasoline Engines Poised to Take on Diesels in US and in Europe for Reduced Fuel Consumption and Emissions

Green Car Congress

Additionally, suggested one of the speakers, advanced SIDI (spark-ignited, direct-injection) engines can take light-duty market share back from diesels in Europe based on the same trends. 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.,

Specific to diesel, it also has the potential to significantly reduce pollutant emissions, like mononitrogen oxide (NO x ), and help meet more stringent regulations including the Real-Driving Emissions test in Europe. Regional highlights include: In North America, more engine downsizing is expected. liter six-cylinder. million in 2016.

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

the Worldwide harmonized Light vehicles Test Procedures (WLTP). This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. The conference.

DOE to award $7M to accelerate fuel and engine co-optimization technologies; Co-Optima initiative

Green Car Congress

Groundbreaking research in the last 10 years has identified combustion engine strategies that—especially if optimized to run on new fuels—would offer significantly higher efficiency and produce fewer engine-out pollutants than current engines. Fuel research will focus on low-GHG advanced biofuel/petroleum blends.
