6. Diesel fuels are middle distillates composed of conventional hydrocarbons, synthetic hydrocarbons and naturally occurring, petroleum-derived, non-hydrocarbons that boil in the range of 130 °C and 400 °C. They are intended for use as motor fuels in high speed compression-ignition diesel engines operating at speeds generally higher than 1,200 r/min. Their ultra low sulphur content limits air emissions.
They must comply with Canadian General Standards Board standard CAN/CGSB-3.517-2013 - Diesel Fuel.
