Claim 2:
3. The ammonia-hydrogen blended fuel control system based on reactivity regulation according to claim 1, wherein the turbulent jet ignition device further comprises an air injector and a second hydrogen injector; a nozzle of the air injector extends into the pre-chamber cavity for injecting air into the pre-chamber cavity, and a nozzle of the second hydrogen injector extends into the pre-chamber cavity for injecting hydrogen into the pre-chamber cavity; the spark plug, the nozzle of the air injector and the nozzle of the second hydrogen injector are arranged on a same side of the pre-chamber; jet holes are positioned in a bottom of the turbulent jet ignition device, and the pre-chamber cavity communicates with the main combustion chamber through the jet holes; and the turbulent jet ignition device has two working modes, namely the double injection mode and the scavenging mode of air injection alone;
when the ECU controls the turbulent jet ignition device to be in the double injection mode, the air injector and the second hydrogen injector respectively inject fresh air and hydrogen into the pre-chamber cavity for forming equivalent gas mixture inside the pre-chamber; and
when the ECU controls the turbulent jet ignition device to be in the scavenging mode of air injection alone, only the air injector injects fresh air into the pre-chamber cavity to scavenge the pre-chamber.
