MULTIFUNCTIONAL MOTOR GASOLINE ADDITIVE Russian patent published in 2017 - IPC C10L10/00 C10L1/22 C10L1/18 C10L1/28 

FIELD: chemistry.

SUBSTANCE: multifunctional gasoline additive contains a gasoline additive with detergent action, which is derived from polyisobutenyl amber acid anhydride produced by reaction of polyisobutenes or polyisobutenes with molar weight of 300 to 5000, with maleic anhydride and/or amino-, and/or amido-, and/or imido groups, obtained by interactio of the said anhydride with aliphatic polyamines such as ethylenediamine, diethylenetriamine, triethylenetetramine or tetraethylenepentamine, as well as additives which are corrosion inhibitors, antioxidants, stabilizers, demulsifiers, antistatic agents, also containing solvents and thinners, wherein a mixture of AR solvent (isomers and homologues of aromatic hydrocarbons, initial boiling point is at least 160°C, final boiling point is not more than 200°C, at least 90 wt % is distilled off till 200°C), polyether based on propylene oxide and glycerol with mol. weight of 500 (Laprol 503), as well as polymethylsiloxane PMS 200 is used as the solvent component.

EFFECT: reduction of carbon deposits in the combustion chamber and deposits on engine valves, reduction of harmful substances in exhaust gases.
