DEVICE FOR EXPRESS-CONTROL OF QUALITY OF AUTOMOBILE GASOLINE Russian patent published in 2006 - IPC G01N27/22 

FIELD: technology for controlling gasoline quality.

SUBSTANCE: device has power source, auto-generator, capacity indicator, detector of information signal, digital indication block, switch, amplifiers with amplifier threshold on input signal, adder and resistor with scaling amplifier. In first position of switch capacity sensor is connected between auto-generator and detector, connected to inputs of n scaling amplifiers, n-1 of which have amplifier threshold on input signal, outputs of amplifiers are connected to inputs of adder, output of which is connected to digital indication block. In second position of switch capacity sensor is connected between power source and resistor, connected to input of scaling amplifier, output of which is connected to digital indication block. In "1" switch position octane level of gasoline is measured, in "2" position - electric conductivity of gasoline is measured.

EFFECT: increased quality and information capacity of control due to possible measurement of octane level and electric conductivity of gasoline.
