National 2010-2011 Survey of E85: CRC Project E-85-2

Description: This study examined the quality of E85 fuel around the country in each of the three volatility classes identified in ASTM D5798-10. Samples were collected from pumps in 21 states between July 2010 and May 2011, with almost 40 samples collected in each class. Parameters tested to assess fuel quality were volatility, ethanol content, water content, acidity, pHe, inorganic chloride and sulfate, and total sulfate. Class 1 samples more often met the volatility specification than samples from other c… more

Quality Parameters and Chemical Analysis for Biodiesel Produced in the United States in 2011

Description: Samples of biodiesel (B100) from producers and terminals in 2011were tested for critical properties: free and total glycerin, flash point, cloud point, oxidation stability, cold soak filterability, and metals. Failure rates for cold soak filterability and oxidation stability were below 5%. One sample failed flash point due to excess methanol. One sample failed oxidation stability and metal content. Overall, 95% of the samples from this survey met biodiesel quality specification ASTM D6751. In 2… more

Impacts of Mid-level Biofuel Content in Gasoline on SIDI Engine-Out and Tailpipe Particulate Matter Emissions: Preprint

Description: The influences of ethanol and iso-butanol blended with gasoline on engine-out and post Three-Way Catalyst (TWC) particle size distribution and number concentration were studied using a GM 2.0L turbocharged Spark Ignition Direct Injection (SIDI) engine. The engine was operated using the production ECU with a dynamometer controlling the engine speed and the accelerator pedal position controlling the engine load. A TSI Fast Mobility Particle Sizer (FMPS) spectrometer was used to measure the partic… more

Fuel Property, Emission Test, and Operability Results from a Fleet of Class 6 Vehicles Operating on Gas-to-Liquid Fuel and Catalyzed Diesel Particle Filters

Description: A fleet of six 2001 International Class 6 trucks operating in southern California was selected for an operability and emissions study using gas-to-liquid (GTL) fuel and catalyzed diesel particle filters (CDPF). Three vehicles were fueled with CARB specification diesel fuel and no emission control devices (current technology), and three vehicles were fueled with GTL fuel and retrofit with Johnson Matthey's CCRT diesel particulate filter. No engine modifications were made.
