FIELD: chemistry.
SUBSTANCE: invention discloses fuel for compression ignition engines comprising the following components: a) at least one low molecular weight polyoxymethylene dialkyl ether of formula RO(-CH2O-)nR in which R represents C1-C4 alkyl group and n=0–5, b) from 0.05 to 5 wt% of at least one polyalkylene glycol alkyl ether of formula R1O(-CH2-CHR2-O-)nH, as well as its mixed polymers, and/or formula H(-O-CHR2-CH2-)n-O-CH2-CH2-O-(-CH2-CHR2-O-)nH, as well as its mixed polymers, where R1 represents C1-C4 alkyl group, R2 represents hydrogen or methyl group, and n=10–200, as well as mixtures of such polyalkylene glycol alkyl ethers, c) from 0 to 20 wt% of at least one high molecular weight polyoxymethylene dialkyl ether of formula RO(-CH2O-)nR, in which R represents an alkyl group, and n=6–10, d) from 1 to 5 wt% of at least one high molecular weight polyethylene glycol dialkyl ether of formula RO(-CH2CH2O-)nR, in which R represents an alkyl group, and n=11–23, e) from 0 to 0.5 wt% of at least one organic peroxide compound, f) from 0 to 0.1 wt% at least one long-chain fatty acid, and g) from 0 to 12 wt% of dimethyl ether, in which the amount lacking up to 100 wt% is contained in at least one low molecular weight polyoxymethylene dialkyl ether. Also disclosed is the use of fuel for compression ignition engines according to any one of the preceding claims in compression ignition engines with or without exhaust gas recirculation (EGR) and as a reducing agent on a selective catalytic reduction (SCR) catalyst.
EFFECT: reduction of CO2 emissions and emission of pollutants, especially solids and nanoparticles.
