ON-BOARD DEVICE
FOR MEASURING FUEL OCTANE NUMBER
FIELD: chemistry; transportation.
SUBSTANCE: according to the
invention, the device has a capacitive sensor, a temperature sensor, an
RC-filter, an amplifier, a precision rectifier, a repeater-amplifier, a keyboard
unit, a display unit, a sinusoidal voltage generator, an analogue-to-digital
converter and a computing unit.
The capacitive sensor is a flow-type
sensor and is in form of a cylinder with longitudinal openings lying radially on
the cross-section of the cylinder. Copper cores are inserted into the openings
and are connected together. The temperature sensor is a pulsed semiconductor
sensor which is built into the cylinder of the capacitive sensor.
EFFECT: increased accuracy of determining fuel
octane number with identification of the type of fuel. 1 dwg
