Zusammenfassung:The invention relates to a process for preparing a fuel mixture based on motor vehicle gasoline having standard qualities in use. According to the invention, the process consists of additivation of the motor vehicle gasoline with octane number 90, having a density of 0.7674 g/cm3, final boiling point of 205°C and a content of 10% methyl-tert-butyl-ether (MTBE), with 7% bioethanol and 5%, in relation to the total volume of fuel, additive for improving octane number based on oxygenated compounds, to result in a stable fuel mixture for spark ignition engines that increases the gasoline anti-knock quality by increasing the octane number COR and reduces the concentration of carbon monoxide in the exhaust gas by 25% vol. as compared to MTBE. Invenţia se referă la un procedeu de obţinere a unui amestec carburant pe bază de benzine auto având calităţi standard de utilizare. Procedeul, conform invenţiei, constă în aditivarea benzinei auto cu cifra octanică 90 , având o densitate de 0,7674 g/cm3 , punct final de fierbere 205°C şi conţinut de 10% metil-terţ-butil-eter (MTBE), cu 7% bioetanol şi 5% raportat la volumul total de combustibil, aditiv pentru creşterea cifrei octanice pe bază de compuşi oxigenaţi, rezultând un amestec carburant stabil pentru motoare cu aprindere prin scânteie care creşte calitatea antidetonantă a benzinei prin mărirea cifrei octanice COR şi reduce cu 25% vol. concentraţia de monoxid de carbon în gazele de eşapament comparativ cu MTBE.
