Abstract
The use of polyoxymethylene di(alkyl polyglycol) ethers of the general formula RO(CH2CH2O)n(CH2O)m(CH2CH2O)nR is described, wherein R is an alkyl radical, n is ≦3 and m is ≦6, as additives to diesel fuels to reduce the particulate emission in self-ignition engines.
Claims8
A method for reducing particulate emission in a self-ignition engine comprising the steps of:
- preparing a diesel fuel mixture including an additive comprising polyoxymethylene di(alkyl polyglycol) ethers of the general formula:
- RO(CH2CH2O)n(CH2O)m(CH2CH2O)nR,
- wherein R is an alkyl radical, n is 1 or 2 and m is 1, and
- combusting the diesel fuel mixture in the self-ignition engine, thereby reducing the particulate emission thereof.
