SYSTEM FOR FEEDING AMMONIA-BASED HYDROGEN FUEL TO AN INTERNAL COMBUSTION ENGINE Russian patent published in 2022 - IPC F02B43/10 F02M21/02 F02M27/02 C01B3/04 

FIELD: engine building.

SUBSTANCE: invention relates to engine building, in particular, to systems for feeding internal combustion engines (ICEs). The ICE feeding system includes an air feed system. The ICE hydrogen feeding system comprises a fuel tank (6) with liquid ammonia, connected with an evaporator (7). The catalytic reduction apparatus (9) installed in the exhaust pipeline (10) of the ICE consists of temperature sensors (11) installed in section (12) with heat intake from exhaust gases and section (13) with heat intake from a built-in electric heater, connected in series with the nitrogen-hydrogen mixture cooler (15) and the electromagnetic nozzle (20) installed in the inlet pipeline (2) and connected with the control unit (21). A primary controlled gear (8) is installed between the evaporator (7) and the catalytic reduction apparatus (9). A secondary controlled gear (16) is installed between the nitrogen-hydrogen mixture cooler (15) and the electromagnetic nozzle (20), connected via a pipeline with the apparatus (17) for increasing the hydrogen concentration in the fuel, containing a membrane filter (18) separating the source fuel into a combustible component hydrogen and a non-combustible component nitrogen and a discharge valve (19) removing non-combustible components.

EFFECT: increase in the proportion of the combustible component in the composition of the fuel-air mixture supplied to the cylinders of the engine.
