1. The fires result from autoignition of sulfur-rich lignite deposits. 2. Consequently, diesel fuel must have a high flash point and a low autoignition temperature. 3. The autoignition temperature of diethyl ether is. 4. Specifically, the danger of autoignition is present as the stabilizer ages and becomes depleted. 5. Whereas charcoal's autoignition temperature is relatively low, carbon's is much greater. 6. Therefore, 2-methylhexane has a lower Autoignition temperature and flash point when compared to heptane. 7. When measured for plastics, autoignition temperature can also be measured under elevated pressure and at 100 % oxygen concentration. 8. Both Jet A and Jet A-1 have a flash point higher than, with an autoignition temperature of. 9. These fires result from either heating the oil to its autoignition point or by oil splattering onto the heat source. 10. Knocking can be reduced by increasing the gasoline's resistance to autoignition , which is expressed by its octane rating.
