Jet ignition combustion system of hydrogen internal combustion engine and injection control method

The invention relates to a hydrogen internal combustion engine jet flow ignition combustion system and an injection control method, the hydrogen internal combustion engine comprises a cylinder body and a piston slidably connected in the cylinder body, the top of the cylinder body is provided with a cylinder cover, and the cylinder body, the cylinder cover and the piston jointly form a main combustion chamber; the main ejector is fixed to the cylinder cover and extends into the main combustion chamber, and the main ejector is used for ejecting hydrogen into the main combustion chamber at the initial stage and the final stage of the compression stroke respectively; the pre-combustion chamber is fixedly connected with the cylinder cover and located on the central axis of the piston, a plurality of jet flow holes communicating with the main combustion chamber are formed in the pre-combustion chamber, and the piston presses mixed gas in the main combustion chamber into the pre-combustion chamber through the jet fl
