METHOD FOR SUPPLYING AND MIXING AMMONIA WITH AIR BEFORE SUPPLYING IT TO CYLINDERS OF DIESEL ENGINE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC F02M21/02 F02B29/04 F02D19/08 B61C5/00 

FIELD: internal combustion engines.

SUBSTANCE: methods for burning ammonia and devices for mixing ammonia with air before being fed into the cylinders of a diesel engine are proposed. A device for supplying and mixing ammonia with air before supplying it to the cylinders of a diesel engine is proposed, including main jet 6, additional jet 7, normally closed valve 8, pressure gauge 9, control valve 10, gear pump 11 with an electric drive, and ammonia container 12. In low-power modes of the diesel engine, ammonia is supplied to diesel engine 1 through main jet 6 under pressure set by control valve 10, and in high-power modes of the diesel engine, normally closed valve 8 opens, and ammonia is supplied to diesel engine 1 through main jet 6 and additional jet 7. Ammonia is supplied to the diesel engine in accordance with the requirement to ensure replacement of diesel fuel with ammonia by 40-60%.

EFFECT: uniform concentration of the mixture of air and ammonia, as well as reduced temperature of the working fluid behind the turbocharger and, therefore, increased power of the diesel engine due to increased air flow into the cylinders.
