The Chemistry of Internal Combustion Engine Deposits — I. Microanalysis, Thermogravimetric Analysis, and Infrared Spectroscopy
As an automobile engine runs, its fuel quality requirements, as measured by the octane number of the fuel needed to inhibit knocking, may change in time. Historically, this phenomenon is referred to as the “ORI”, standing for octane requirement increase.
