Figure 9.2 - Determination of fuel density by hydrometer
The mark or diesel fuel class is chosen according to the
most important parameters: cetane number, clouding
temperatures, hardening, kinematic viscosity, density. The
choice is to be stopped on the mark, which is the most
appropriate for the results obtained for the studied diesel fuel.
An example of the values of diesel fuel indicators is
given in Table. 9.3.
Sample diesel fuel (Table 10.4) closest to summer diesel
fuel brand S (DSTU 3868-99), therefore, its indicators are
recorded, and since the actual deviations of indicators from the
standard are not observed, in front of each indicator, the word
"no" is indicated. At the same time, it is stated that this fuel
