Study finds gasoline exhaust contributes more to formation of secondary organic aerosols than diesel

Green Car Congress

Contrary to expectations, exhaust from gasoline vehicles contributes more to the production of secondary organic aerosols (SOA) than exhaust from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA’s Earth System Research Laboratory (ESRL) and other colleagues.

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.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. Background.

UC Berkeley study quantifies LD gasoline on-road emissions

Green Car Congress

Based on on-road measurements in their study, a team from the University of California Berkeley has estimated that, as of 2010, light-duty (LD) gasoline vehicles were responsible for 85% of CO; 18% of NO x ; 18% of organic aerosol (OA); and 6% of black carbon (BC) emissions from on-road motor vehicles in the United States.

DENSO Develops Exhaust Gas Temperature Sensor With Improved Temperature Detection Accuracy

Green Car Congress

DENSO Corporation has improved the temperature detection accuracy of its newly developed diesel exhaust temperature sensor. To improve the sensor’s temperature accuracy, DENSO increased the probe length to almost twice that of the conventional product and extended the sensing tip into the exhaust pipe. Click to enlarge.
