How Do ORYXE Energy’s Diesel Fuel Additives Work?
In diesel engines, nitrogen oxides (NOx) are created through the oxidation of molecular nitrogen (N2). Although there are other NOx formation mechanisms present as well, the amount of NOx produced is mainly related to the peak temperature in the combustion chamber. Therefore, one route to NOx reduction is lowering the peak temperature.

ORYXE Energy’s proprietary diesel fuel additives contain both cetane-enhancing, complex-hydrocarbon compounds and proprietary, renewable-based materials. Together, these components alter the rate of combustion reactions to reduce pollutant emissions.

Upon injection into the combustion chamber, the cetane-enhancing compounds rapidly decompose and form free radicals. The free radicals react and initiate the gaseous phase of combustion earlier in the compression cycle. Therefore, ignition takes place earlier, allowing the vaporized fuel to burn over a longer period of time. As a result, a lower peak temperature is reached and less NOx is produced. The early initiation of combustion reactions also helps reduce the concentration of unburned hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) in the exhaust gases.

The renewable-based materials regulate the rate of flame propagation producing a smoother, more controlled rate of combustion. This further reduces the peak flame temperature, and lowers NOx.
