Some mechanical, optical, miscellaneous and thermal properties for the local samples of gas oil and diesel fuels

الملخص EN

Some of mechanical, optical, miscellaneous and thermal properties as density (d), Specific gravity (Sp.

gr.), thermal expansion efficient (α), Aniline point (A.P), Diesel index (D.I), Refractive index (R.I), heat of combustion (gross calorific value) (Q),) heat of Latent (L) and the percentage of hydrogen (%H ) , the acidity and %ash were determined.

The ratio of some impurity and the standardization of these samples to the usage were determined also.

From this studied that show the addition of kerosene to gas oil (at slight amount of it in local's market) may be good the storage property, so the sample (2) is making high value of thermal expansion compared with other samples.

In sprit of, the values of Sp.

gr of samples 6, 7 &8 were occurred in standard range (19), but the amount of %Ash may be very high that caused the damage of car's engine in the little time.
