  • Patent number: 5993054
    Abstract: Additives are blended with a stream of liquid, for example of diesel fuel, by injecting at least two different additive compositions into the stream, and adjusting the rates of injection and the relative proportions of the injected additive compositions. This enables the consumption of additives to be minimized while enabling desired fuel characteristics to be maintained despite variations in the characteristics of the untreated liquid. The rates of injection may be adjusted by an automatic controller (32) in response to signals from sensors (28, 30) representing characteristics of the liquid before and after treatment.
