Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings. as a limitation of the present invention.

As shown in FIG. 1, a microporous intermittent detonation jet engine includes an engine casing 1, the engine casing 1 has an intake port and an exhaust port, and the engine casing 1 is close to one end of the intake port and along the intake port. In the direction from the air port to the exhaust port, an intake fan 2 and an intake valve plate structure 3 are arranged in sequence. The part of the engine casing 1 from the oil intake valve plate structure 3 to the exhaust port is a combustion chamber. The combustion chamber One end close to the exhaust port is provided with a plurality of spark plugs 4;

The oil inlet valve plate structure 3 is composed of an oil and gas orifice plate 31 and an oil and gas hole valve plate 32 that cooperate with each other. The oil and gas orifice plate 31 and the oil and gas hole valve plate 32 both have a plurality of small holes 33 for oil and gas to pass through. , and the small holes 33 on the oil and gas hole valve plate 32 are staggered with the small holes 33 on the oil and gas hole plate 31, some small holes 33 on the oil and gas hole plate 31 are connected to the oil pipe 5, and the oil and gas hole valve plate 32 There is a plug 34 that cooperates with the small hole 33 on the oil and gas hole valve plate 32;

The inner wall of the engine casing 1 has a chute 11 for fixing the oil inlet valve plate structure 3. The oil and gas orifice plate 31 corresponds to the direction of the air inlet and is integrated with the engine casing 1.

During the implementation, first, when starting the air intake fan 2, a large amount of air passes through the small holes 33 on the oil and gas orifice plate 31, and at the same time, the oil pipe 5 connected to some small holes 33 of the oil and gas orifice plate 31 sprays fuel oil, and the fuel oil and air pass through the oil and gas at the same time. The small holes 33 on the orifice valve plate enter the combustion chamber. When the fuel and air enter the combustion chamber and reach the spark plug 4, they are ignited and violently combusted and detonated. Then, the oil and gas orifice valve plate 32 moves to the oil and gas orifice plate 31 under the action of detonation. The plug 34 on the oil and gas hole valve plate 32 blocks the small hole 33 on the oil and gas hole plate 31, so that the fuel and air do not enter the combustion chamber. At this time, the gas generated by the fuel after combustion can only be discharged from the exhaust port. Tempering, on the other hand, makes the burned gas more powerfully ejected. Finally, after the gas in the combustion chamber is ejected, the pressure of the combustion chamber is less than the wind force of the intake fan 2. The direction of the orifice plate 31 moves so that the air and fuel can enter the combustion chamber again, and when the fuel reaches the spark plug 4, the fuel is re-combusted and detonated to form a cycle, so that the fuel is intermittently combusted and detonated in the combustion chamber, saving fuel.
