A Physicochemical Study of the Adulteration of Motor Gasoline with a Mixture of Aliphatic and Aromatic Hydrocarbons

Express method for total content assessment of aromatic hydrocarbons and oxygen in finished gasolines by refractometry and densimetry

“…Magneto-optical benzene index BIN is associated with the volume fraction of aromatic hydrocarbons v aromatics in gasolines by Eq. (16) v…”

“…The sensitivity of each method to a particular group of compounds (hydrocarbons) allows on combining them (using together) to determine the content of mixtures, to evaluate their performance properties and their identification. The need to develop the methods of rapid identification of petroleum products is dictated by the fact that the volume of counterfeit products, especially in the motor fuels market, remains significant [13][14][15][16]. It is generally known that one way of falsification of motor fuels is replacement of components to cheaper and environmentally hazardous ones, which leads to significant deterioration in performance properties of fuels, and to increased carbonization, thereby to resource reduction of the engine.…”

Power Supply for Excitation Mechanism of Motor in Electrical Appliance

“…Furthermore, the attractively coupled reverberation WPT innovation works without the attractive center, the excitation source and the helped excitation transmitting winding can be set outside the electric machine, a generally additionally space is allowed between the supported excitation transmitting winding and the getting one, the exchange effectiveness is exceptionally well meanwhile. This brushless excitation component works dependably with great warmth scattering and basic support [7].…”

Quality assessment of gasoline using comprehensive two‐dimensional gas chromatography combined with unfolded partial least squares: A reliable approach for the detection of gasoline adulteration

“…The procedure of physicochemical tests includes measurements of relative densities, final evaporation point, octane numbers, amount of anhydrous ethanol, etc. . However, to perform these tests large amounts of gasoline samples are required and most of the procedures require manual operations that are tedious and time‐consuming.…”
