Prechamber jet disturbance intensified combustion system

A prechamber jet disturbance intensified combustion system, comprising a main combustion chamber (1) and a main fuel injector (4), the lower end of a fuel nozzle of the main fuel injector (4) is located inside the main combustion chamber (1);

• wherein, two prechambers (2) are arranged above the main combustion chamber (1), the prechambers (2) are connected with the main combustion chamber (1) by prechamber channels (3), an auxiliary fuel injector (5) is arranged outside each prechamber (2), the auxiliary fuel injectors (5) are located on the two sides of the main fuel injector (4) respectively, and the lower end of a fuel nozzle of the auxiliary fuel injector (5) is located inside the corresponding prechamber (2).
• wherein, through the prechamber channels (3), high-pressure potential energy of the prechambers being converted into high outlet gas momentum, so the prechamber channels (3) need to meet the requirements of low flow resistance of compressed gas inlet and high combustion injecting momentum outlet;
• and the number of the prechamber channels is at least one, and the shape of the prechamber channels are selected from a shrinking-broadening shape, a gradually-broadening shape, a gradually-shrinking shape or a cylinder shape.
