            the specifications for the brand or diesel fuel class.

                   9.4  Individual  task.  Each  student,  on  the  basis  of  a
            positive assessment, receives an individual task for laboratory
            work at a poll in the class.
                   9.4.1 Describe the  methods  for determining the cetane
            number of diesel fuel.
                   9.4.2 What influences the cetane number of diesel fuel.
                   9.4.3  What  indicators  of  diesel  fuel  affect  its
            consumption in the system of power supply to the ICE.
                   9.4.4. Marked domestic and imported diesel fuels.
                   9.4.5 Provide alternative fuels for diesel ICE.
