Embodiment Construction

[0039] The present invention has studied three kinds of additives, and it is respectively mixed with commercially available diesel oil (particularly the EN590 diesel oil of low sulfur content), so that the oxygen in each fuel mixture that finally obtains is 9wt.%, and this ratio is suitable for figure 2 . In this way three mixtures are obtained, each containing different additives, the final mixtures being comparable since they all correspond to 9 wt.% of oxygen. The above ratio was chosen because this value corresponds to a mixture of diesel and cyclohexanone containing 9 wt.% of oxygen, so its performance can be compared with two "standard" oxygenated additives commonly used to reduce soot particle emissions, in particular TPGME (Tripropylene glycol monomethyl ether) and DBM (dibutyl maleate) performance comparison. The following measurements are performed to determine emission values, especially those of NOx, HC, CO and soot: Chemiluminescence (CL), Flame Ionization Detec...

Abstract

A liquid fuel composition comprises mixture of hydrocarbons containing a cyclic hydrocarbon compound having at least five carbon atoms and at least one oxygen atom.

Description

technical field [0001] The present invention relates to the use of at least one soot particle emission inhibiting compound in a liquid fuel composition comprising a mixture of hydrocarbons. The invention also relates to a method for reducing the emission of soot particles in the exhaust gas of an internal combustion engine and to such a liquid fuel composition. Background technique [0002] U.S. Patent No. 4378973 discloses a diesel oil composition, wherein, in order to reduce the emission of soot particles, a mixture of cyclohexane and at least one oxygenate is added to it, the amount of cyclohexane reaches 0.5-5.0 wt.%, and the amount of oxygen-containing compounds is 0.5-5.0 wt.%. Suitable examples of oxygenates mentioned are isobutyl heptyl ketone, acetone, tetrahydrofuran, 1,2-epoxybutane, methyl ether, propionaldehyde, ethanol, 2-ethylhexanol or Primary alcohols with carbon atoms. The explanation provided by the above US patent is that oxygenates burn cleaner than h...
