Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter

Green Car Congress

Although gasoline direct injection engines (GDI) are a favorable technology for reducing fuel consumption and greenhouse gas emissions, recent studies have shown that GDI vehicles could emit more PM than traditional PFI (gasoline port fuel injection) vehicles as well as heavy-duty diesel trucks equipped with diesel particulate filters.

Effect of syngas composition on combustion and exhaust emission characteristics in a dual-fuel engine operated in PREMIER combustion mode

Green Car Congress

Researchers at Okayama University (Japan) found that conventional combustion in a pilot-ignited, supercharged duel-fuel engine powered with different types of syngas at various equivalence ratios can be transformed into combustion with two-stage heat release. The H 2 and CO 2 content of syngas affected the engine performance and emissions.
