METHOD FOR SUPPLYING COMBUSTIBLE GAS AND DIESEL FUEL TO THE WORKING CYLINDERS OF THE GAS DIESEL Russian patent published in 2022 - IPC F02D19/06 F02D19/10 F02M43/00 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in fuel supply systems of internal combustion engines (ICE). A method for supplying combustible gas and diesel fuel to the working cylinders 8 of the gas diesel is proposed, which consists in the fact that one part of the combustible gas in a percentage ratio, in accordance with the program for controlling the operation of the gas diesel, is fed through the inlet nozzle 13 to the boost compressor 5, where the combustible gas is mixed with air, then in the form of a gas-air mixture is sent to the air collector 16 of the gas diesel and through the inlet valves to the working cylinders at the cylinder filling cycle. At startup, at idle run and low loads, the combustible gas and the ignition dose of diesel fuel are enriched with hydrogen or synthesis gas 31 in a percentage ratio of 1-5%, while the ignition dose of diesel fuel at idle and low loads is heated with the heat of cooling water, gas diesel water to a temperature of 60-90°C.

EFFECT: improvement in the quality of diesel fuel atomization and combustion of mixed fuel, a reduction in the specific effective consumption of diesel fuel, hazardous emissions and an increase in the effective power of gas diesel.
