Definitions

• the invention relates to means for cooling internal combustion engines
• ICE (hereinafter ICE) and can be used to improve the efficiency and reliability of ICE cooling and its operation.
• Known cooling methods are air, liquid, and mixed (Wikipedia).
• air heat is transferred to the atmosphere through a radiator on a cylinder in a piston engine or by passing air in gas turbine engines.
• liquid water passes through the channels in the engine, receives heat and carries it to the external environment. This method is usually used in water transport.
• the mixed method the liquid is not discharged into the environment, but is cooled in a separate air cooler.
• the objective of the invention is a cooling method applicable for any type of ICE with a minimum of changes in design, details and built-in automatic adjustment of the thermal regime individually in each combustion chamber of the engine, without changing the operating modes of the motor.
• liquid injection nozzles and a temperature sensor are installed in the combustion chamber, the signal from which is converted into control commands for the operation of the nozzles, a liquid tank and a high pressure pump for supplying liquids to the nozzles are also necessary.
• the internal cooling method works as follows. When starting the engine and reaching the set temperature in the compressor station, liquids are injected by nozzles into the combustion chamber after each combustion cycle of the fuel mixture (or in the final part of the combustion zone, when used on gas turbine engines). Sprayed liquids will evaporate and cool the CS.
• the amount of injection fluid is determined separately for each compressor according to the temperature sensors in the compressor.
• the temperature range in the compressor must be such that there is no overheating of the motor parts and there is no liquid phase in dangerous quantities for the engine.
• the signals from the shaft position sensor usually used in engines, or use the signals of the ignition system.
• the internal cooling method allows, in addition to the main cooling effect, to perform preliminary injection and cooling of the combustible mixture until ignition. This prevents detonation and allows to increase the filling and compression ratio of the mixture. Which in turn increases the efficiency of combustion of the air-fuel mixture.
• the relatively low temperature in the combustion chamber reduces the formation of harmful nitrogen dioxide. This is useful because the filtration and neutralization systems of nitrogen dioxide in modern cars are very expensive.
• the main cooling injection is made after the combustion of the fuel mixture. It regulates the temperature of the engine.
• internal cooling is used not in a separate cycle, but in each operating cycle of the engine and is additionally possible on the exhaust cycle.
• the amount of liquid for injection and cooling of each compressor is determined individually based on feedback according to temperature sensors. Therefore, for any local malfunctions and deviations from a given temperature range, you can automatically immediately turn off the fuel supply to a specific compressor station and avoid overheating of engine parts.
• Method of internal cooling of the internal combustion engine is applicable to all types of internal combustion engines, and does not require significant changes in the design of the motor. Provides controlled cooling of the engine in places of a source of heating and at that moment when further heating is not required. Allows you to increase the power, efficiency and environmental friendliness of the motor.
