The present invention is directed to vapor suppression of liquids through disposing a layer of surfactant onto the surfaces of liquids for surfactants having a density greater than the liquid and regardless of surface tension spreadability issues, and compositions comprising the surfactants in aerosolized form.

A method for the continuous production of an improved diesel fuel, having enhanced ignition characteristics, more particularly with a greater electric conductivity, enhanced cetane numbers and lubricity and with greater percentage of complete combustion, resulting in less soot production and NOx reduction at the same time in an internal combustion diesel engine, breaking the tradeoff in the emission of those two pollutants from an internal combustion diesel engine.

Provided is a fuel-reducing composition for diesel internal combustion engines, which includes nanosized crushed nanomaterials and uses a lubricity improver to ensure sufficient dispersion. This allows for the cleaning of the combustion chamber and promotes complete combustion, which enhances output while reducing fuel consumption. By using the fuel-reducing composition for diesel internal combustion engines formed according to the preferred embodiment of the present invention, the size of the nanomaterials is limited, allowing for efficient cleaning of the combustion chamber without interfering with combustion. Without the use of surfactants for the dispersion of nanomaterials, a lubricity improver is employed to facilitate smooth dispersion while simultaneously protecting the combustion chamber of the engine and promoting complete combustion. Since the nanomaterials do not adhere to each other due to their size limitation and the use of the lubricity improver, combustion proceeds smoothly, leading to complete combustion and producing the desired effects.

A diesel fuel additive includes a cetane number improver and an at least one organometallic combustion catalyst in solution and/or at least one metal-oxide combustion catalyst in suspension.
