Abstract
The amount of smoke, soot and invisible particulates emitted with the exhaust of engines run on diesel fuel is reduced by incorporating therein an additive consisting of a synergistic mixture of cyclohexane with an oxygenated compound which readily gives up oxygen during combustion. Also disclosed is a method of operating a diesel engine using the fuel of the invention.
Claims7
A diesel fuel composition comprising a mixture of hydrocarbons boiling in the range of 320.degree. to 700.degree. F. and a particulate-suppressing amount of a mixture of cyclohexane with at least one oxygenated compound selected from the group of aldehydes and ketones having from 3 to 16 carbon;
- normal alcohols having from 2 to 26 carbon atoms in the chain;
- ethers or cyclic ethers having from 2 to 16 carbon atoms and mixtures thereof;
- said compound being present in an amount sufficient to provide from 0.0001 to 1.5 weight percent of oxygen to said fuel.
