USING DIALKYLPOLYGLYCOL ETHERS OF POLYOXYMETHYLENE AS DIESEL FUEL ADDITIVE FOR REDUCING EMISSION OF SOLID PARTICLES WITH EXHAUST GASES IN SELF-IGNITION ENGINES Russian patent published in 2013 - IPC C10L1/198 C10L10/02 

FIELD: chemistry.

SUBSTANCE: use of dialkylpolyglycol ethers of polyoxymethylene of general formula RO (CH₂CH₂O)n(CH₂O)_m(CH₂CH₂O)_nR, wherein R is an alkyl, n assumes a value from 1 to 3 and m equals 1, as a diesel fuel additive for reducing emission of solid particles with exhaust gases in self-ignition engines. The dialkylpolyglycol ether of polyoxymethylene is present in amount less than about 15 vol. %. The diesel fuel contains up to 10 vol. % fatty acid methyl esters (FAME) or is a pure FAME biodiesel fuel or a synthetic diesel fuel.

EFFECT: compounds have relatively high volatility, which increases the fraction of the combustion mixture and, consequently, provides uniform combustion with low emission of solid particles in the engine.
