AUTOMATED SYSTEM FOR DETERMINING THE GRADE OF AVIATION GASOLINE Russian patent published in 2022 - IPC C10L10/10 G01N33/22 

FIELD: aviation.

SUBSTANCE: invention relates to the field of determining the knock resistance of aviation gasolines. An automated system for determining the grade of aviation gasoline is proposed, containing a single-cylinder supercharged injection engine, a load machine with a torque meter, a compressor, an air line, receivers, an injector, a fuel line, where a fuel flow meter is installed, an air flow meter, characterized by the fact that the cylinder head of the engine has a reported with the combustion chamber of the engine - a cylindrical groove in which a pressure sensor of cylinder gases is installed with the formation of a cavity on the side of the combustion chamber of the engine, while the volume of this cavity is not more than 0.02 of the volume of the engine combustion chamber, the automated control module contains a cylinder gas pressure change recorder connected to a cylinder gas pressure sensor, and a software information processing unit, to the inputs of which a fuel flow meter, an air flow meter and a torque meter are connected, and the fuel tank is made in the form of separate tanks connected in parallel through individual shut-off valves to the fuel supply line to the injector.

EFFECT: increasing the accuracy and reliability of determining the grade of aviation gasoline with a simultaneous reduction in the duration of testing.
