Study finds modern diesel cars emit fewer carbonaceous particulates than gasoline cars

Green Car Congress

A new study by an international team led by researchers from the Paul Scherrer Institute (PSI) in Switzerland has found that modern diesel passenger cars equipped with diesel particulate filters (DPFs) emit fewer carbonaceous particulates than gasoline-powered vehicles.

Researchers propose low-temperature SOFC unit for reducing NOx and oxidizing HCs in lean-burn engine exhaust

Green Car Congress

Their SOFC system can be operated without consuming the anode fuel (a reductant) at temperatures near that of the engine exhaust to eliminate the need for reductant refilling and extra heating. The NO x concentration in the exhaust of an automotive gasoline engine with spark ignition can be as high as 4000 ppm.

Study quantifies impact of fuel composition on PM emissions from gasoline direct injection engines

Green Car Congress

Researchers from Tsinghua University and Peking University have investigated the effects of fuel properties on particulate emissions gasoline direct injection engines (GDI). Higher aromatics in gasoline resulted in much higher PM (mass), PN (particle number) and PAHs emissions, with higher toxicity to human health. Storey et al.

Using a Diesel-Gasoline Blend to Reduce NOx and Smoke Emissions and Improve High-Efficiency Range of LTC Engine

Green Car Congress

Researchers from Shanghai Jiao Tong University and the University of Michigan report on the use a “dieseline” blend—an 80:20 blend of diesel and gasoline—for the simultaneous reduction of NO x and smoke emissions in a Low Temperature Combustion (LTC) mode and the extension of low-emission and high-efficiency operational range of the engine.
