Abstract

Method and devices for fuel characterization and optimization on-site at a fuel delivery dispenser are disclosed. Fuel properties associated with a fuel sample of a fuel can be measured by mid-infrared analysis and displayed. Pre-determined preferred values for the fuel properties for the particular vehicle can be determined by inputting the model and type of vehicle into a processing means and correlating the vehicle information with the preferred values. The preferred and measured values can be compared and the comparison displayed. A fuel sample rating for the vehicle can be performed based this comparison and displayed. An optimal dispenser fuel for the vehicle can be identified based on a comparison between the preferred values and the values for the fuel properties for each of the dispenser fuels. In one embodiment, driveability index can be the fuel property determined in situ and in real time. In other embodiments, octane number, and Reid vapor pressure can be similarly determined.
