Cleanliness and Quality

摘要

They're lurking out there in diesel fuel tanks: Small particles of debris, too tiny to see, wearing out fuel injectors; water, lying in wait at the bottom, causing corrosion debris, reducing fuel lubricity, and hosting microbes (fungi and bacteria) that feed on the fuel and form filter-plugging slime and corrosive acids; and, finally, assorted byproducts of the fuel-aging process, including asphaltenes, tar-like substances that agglomerate under engine heat and pressure to plug filters and interfere with combustion.
