Chemical and Mutagenic Characteristics of Diesel-Exhaust Particles from Different Diesel Fuels

摘要

A potential for increased use of a wide variety of diesel fuels has increased the importance of studies to determine whether the nitrogen content of different fuels affects the chemical and mutagenic characteristics of the particles produced during combustion. In this study, the exhaust particles from five diesel fuels with various nitrogen and aromatic hydrocarbon contents were examined. The fuels included minimum quality No. 2 (Min. Qual.), jet fuel (JP-7), shale diesel fuel-marine (DFM), a base fuel plus heavy aromatics and hexylnitrate (BF + HAN + HN), and the base fuel plus isoquinoline (BF + IQ). Particles used in the study were generated using a Mercedes 240D vehicle driven through five consecutive Highway Fuel Economy Tests. (ERA citation 08:044687)
