METHOD OF COMPARATIVE EVALUATION OF EFFICIENCY OF FUEL COMBUSTION PROMOTERS IN COMBUSTION CHAMBER OF AIR-JET ENGINE Russian patent published in 2018 - IPC G01N33/22 G01N25/24 

FIELD: engines and pumps.

SUBSTANCE: at the first step, a reference fuel and air with set temperature and pressure are supplied to the evaporating combustion chamber, excess air coefficient is set from combustion condition exceeding 95% of fuel, air and fuel consumption is increased at constant air excess factor to ensure poor explosion of flame in the combustion chamber, and value of volumetric flow rate of air corresponding to flame blasting mode is registered, at the second stage fuel is used with additive-combustion promoter, which is supplied to an evaporation chamber of combustion at flow rate equal to initial fuel consumption at the first stage, air is supplied with excess air coefficient at temperature and pressure, air and fuel consumption is increased at constant air excess factor to ensure poor explosion of flame in the combustion chamber, and value of volumetric flow rate of air corresponding to flame blasting mode is registered, and evaluation of efficiency of combustion promoting additive is carried out by ratio of volumetric flow rates of air registered during the first and the second stages.

EFFECT: improved evaluation accuracy.
