Claim Text:
1. A fuel composition identification system for an automotive vehicle combustion engine, the system comprising: a fuel heating resistor placed in a position in the fuel tank or along the fuel line, in direct contact and exchanging heat with the fuel; an electronic control unit connected to the resistor which applies a controlled feed power to the resistor; a metering device which measures a parameter of the heating resistor, the parameter being the current on the resistor or the surface temperature of the resistor, and sends the metered values to the electronic control unit, wherein the electronic control unit applies constant power values to the resistor during pre-set time intervals and monitors the heating resistor parameter values measured by the metering device during each time interval (t wherein: q″max=maximum critical heat flow W=maximum critical power applied to the resistor at time (t m
