Short Answer Questions are 10 points each

1. Upon exposure to air, biodiesel oxidizes. This oxidation is critical to diesel fuel quality. Therefore, advances must continue to be made in the storage, transport, and use of biodiesel. In your own words, describe how biodiesel oxidation occurs, how it effects the diesel engine, and how oxidative properties are tested. (from the lecture).
2. Biodiesel almost always needs an antioxidant additive to meet the oxidative stability requirements in the ASTM standard. However, antioxidants are oxidation delayers, not oxidation preventers. What other methods may be used to delay biodiesel oxidation? (Page 211/212. Chapter 6.4).
3. According to the BIOSTAB Project study, how long can biodiesel be stored under normal conditions? (Page 213, chapter 6.4)
4. What dictates the efficiency and amount of antioxidant used? (Page 213, chapter 6.4)
5. What is ULSD? (Page 219, chapter 6.5)
6. In terms of lubricity, has the new Ultra Low Sulfur Diesel improved or decreased the lubricity of diesel engine parts? (Page 219, chapter 6.5)
7. What is neat biodiesel and how have low level blends of neat biodiesel helped lubricity of engine parts? (Page 220, chapter 6.4)
8. Diesels rely on the fuel to lubricate the injectors and fuel pumps. What are the two tests used to determine lubricity and which one became the ISO standard? (Page 219, chapter 6.5)
