ULSD stands for Ultra Low Sulphur Diesel

详情

ULSD stands for Ultra Low Sulphur Diesel. It is sometimes referred to as the new, onroad (highway) *5 ppm LSD (Low Sulphur Diesel). It is a clean burning diesel fuel that is
defined by Environment Canada to have a maximum sulphur content of *5 mg/kg (parts per
million mass or simply ppm). ULSD will completely replace the current on-road LSD, which can
have as much as **0 ppm sulphur content. ULSD is required for use in engines that will be
equipped with advanced emission control systems starting with the ***7 model year.
ULSD may smell or appear slightly different from the current on-road LSD.

ULSD formulation is not expected to have any different impacts than the previous diesel
fuel formulation. Compared to gasoline, all distillate / diesel fuels have very low solubility in
water. ULSD will also have very low water solubility and is not expected to present any
significant ecological differences compared with **0 ppm LSD should it be released to surface
waters or ground water.
