Abstract: The present invention relates to fuel additives, fuel compositions and methods of manufacture in which the additives are provided to impart desired properties to fuels. These properties include, without limitation, reduction of nitrogen oxide and particulate emissions from the exhaust stream of internal combustion engines using the fuels. Preferred embodiments of an additive form of the composition include a nitrogen-containing compound selected from the group consisting of urea, cyanuric acid, triazine, ammonia and mixtures thereof, a carrier blend comprising an alkoxylated alcohol, a polyalkylene glycol ester and an alkanolamide and water. The additive may be provided in a concentrate form by addition of a solvent or may be provided as a final form fuel composition. A method of additive manufacture and is disclosed.

Abstract: A method of verifying vehicle emissions includes the steps of testing a refined fuel for emissions, treating the refined fuel following the testing thereof for emissions, and then testing the treated refined fuel for emissions. The refined fuel measurements are compared with the treated refined fuel measurements to determine reduction in emissions of the fuel. This data is transmitted to a computer. The treated fuel is dispensed to a vehicle, such as a diesel truck, at a fuel dispensing station where the vehicle identification is read from the vehicle and, with the fuel data, is transmitted to the computer where the computer can match the fuel measurement data to the vehicle identification and fuel dispensing information. The process also includes the attaching of an on-board emissions monitor to the exhaust of the vehicle, which monitoring data is stored and transmitted during refueling to the computer with the refueling data.
