Swiss team concludes that particulate filters should be mandatory for GDI engines

Green Car Congress

In the spring 2014, the GasOMeP project (Gasoline Vehicle Emission Control for Organic, Metallic and Particulate Non-Legislative Pollutants) got underway. The carcinogenic potential in one cubic meter of exhaust gas from gasoline direct injectors is up to 1,700 times higher than the EU limit for clean air. Click to enlarge.

Pinnacle’s opposed-piston scooter engine can meet NOx target with lean operation and ignition delay; little fuel economy hit

Green Car Congress

Fuel efficiency and cost savings are achievable if the engine’s ignition limits are sufficient to maintain stable combustion at a lean enough mixture ratio to meet NO x emissions without compromise to customer drive feel. —Willcox and Cleeves (2013). When the entire vehicle costs around $700, that’s a significant difference.

CPT and Eminox to collaborate on development of retrofit electric supercharging and aftertreatment solutions for heavy-duty vehicles

Green Car Congress

Essentially, the use of the Cobra supercharger helps reduce engine-out emissions, effectively making Eminox’s task easier. Having better control over the combustion process reduces the emission load on the exhaust aftertreatment systems. Phil Bush, technology manager at Eminox.

Ford / AVL study concludes mid-level ethanol blend attractive as a long-term future fuel for use in optimized engines in US

Green Car Congress

The team presented a paper on their work at the 2013 SAE World Congress in Detroit. Ford engineers also presented two other papers evaluating the effects of low to mid-level ethanol blends in spark-ignited engines at the conference. Emissions of PM, toxic compounds, and off-cycle emissions due to enrichment would drop significantly.
