The utility model relates to a fuel engine, especially a water-oil mixed combustion energy-efficient flying boat flying submarine engine who takes infrared muffler suitable for aircraft, locomotive, naval vessel, submarine.

At present, engines applied to various fields use single fuel oil such as kerosene, gasoline and diesel oil, on one hand, the fuel oil consumption is large, the cost is high, on the other hand, the burn-off rate is only 55-75%, and on the other hand, a large amount of CO and CO are generated and discharged to the atmosphere in the combustion process₂And the like, and the harmful gases and the smoke dust form environmental pollution. In addition, when the engine works, the noise is larger than 135 decibels, and serious noise pollution is formed, which is all the problems to be solved urgently in the prior engine.

The invention aims to solve the problems in the prior art and provide the water-oil co-combustion high-efficiency energy-saving airship flying submersible engine with the infrared silencer, which has the advantages of simple structure, less oil consumption, high burnout rate, low operation cost, no harmful gas emission and no noise pollution and is suitable for airplanes, locomotives, ships and submarines.

The invention aims to realize the following steps: the utility model discloses a: casing, intake duct, combustion chamber, propulsion spray tube, fuel delivery pipe and nozzle, intake duct, combustion chamber, propulsion spray tube are located the casing in proper order, and the nozzle is installed side by side on the fuel delivery pipe in the casing to be located between intake duct and the combustion chamber, its characterized in that: the device also comprises a high-temperature detector, wherein a probe of the high-temperature detector is positioned at the position of the propelling spray pipe, a water-oil heating decomposition pipeline is also arranged in the combustion chamber and the propelling spray pipe, an outlet of the water-oil heating decomposition pipeline is connected with an inlet of a fuel conveying pipe in the machine shell, an inlet of the water-oil heating decomposition pipeline is connected with an outlet of a water-oil mixing pipe outside the machine shell, and an infrared silencer with uniformly distributed through holes is also arranged at the position of a pipe orifice of the propelling spray pipe.

The utility model discloses fuel delivery pipe is three, and parallel mount is between intake duct and combustion chamber, and its import all communicates with each other with water oil heating decomposition pipeline, and infrared muffler's appearance is a flat end bowl shape.

The utility model discloses fuel delivery pipe is one, and its import communicates with each other with water oil heating decomposition pipeline, and the appearance of infrared muffler is the cap shape.

The utility model discloses high temperature detector adopts general technique.

When the fuel nozzle is used, pure fuel oil is firstly input, is sprayed out from the nozzle, is ignited by the electronic igniter and is mixed with air entering from the air inlet channel for combustion, and the temperature is rapidly increased. The high-temperature gas is expanded and accelerated through the propelling nozzle, and is discharged from the nozzle at high speed to generate thrust. When the temperature rises to be more than 500-800 ℃, the high-temperature detector sends an instruction, the water control switch is turned on, water and oil are mixed in the pipeline and enter a water-oil heating decomposition pipeline in the combustion stator propelling spray pipe, the temperature is raised, and the water-oil heating decomposition pipeline is decomposed according to the following formula:

the decomposed combustible gas is sprayed out from the nozzle and mixed with air for combustion. The flame is similar to oxyhydrogen flame during combustion, and the temperature can reach 2800-3000 ℃, so that the generated thrustis large. As the mixed combustion of water and oil is more sufficient than the single combustion of fuel oil, the flame temperature can be higher than 500 ℃ and 800 ℃, most of decomposed CO is almost completely combusted, and a small part of O₂CO produced₂And CO₂And continuously decomposing, burning and releasing heat according to the following formula:

therefore, the water-oil mixed decomposition combustion can discharge CO and CO compared with the combustion of fuel oil alone₂90% less. In addition, when high-temperature fuel gas is combusted and sprayed out of the propelling spray pipe, high noise generated by friction and vibration with air is eliminated due to the fact that the infrared silencer with the uniformly distributed through holes is arranged outside the nozzle. At the same time, because the silencer is made of AL₂O₃The heat-resistant material is made of a heat-resistant material, so that infrared waves are generated when high-temperature gas is combusted and sprayed out of the through hole. On one hand, infrared wave radiation promotes the water and oil in the water and oil heating decomposition pipeline positioned at the inner side of the silencer to be heated and decomposed, and on the other hand, promotes high-temperature fuel gas to be further decomposed into C, H, O atoms for combustion.

Compared with the prior art, the utility model, have following advantage:

the structure is simple, the combustion temperature is high, the generated thrust is high, and the navigational speed can be improved by 30-40%.

Secondly, the fuel consumption is low, the fuel can be saved by 30-40 percent, and the burning rate is as high as more than 99.8 percent, SO that almost no CO or SO is generated₂、CO₂And harmful gases and no smoke dust are discharged into the atmosphere, so that the environmental pollution is reduced.

And thirdly, due to the arrangement of the infrared silencer, the high noise volume is reduced to be below 35 decibels, and high noise pollution is eliminated.

Fourthly, because the cheap water is adopted to replace part of fuel oil, the operation cost is greatly reduced.
