Hydrogen engine cylinder cover

The invention discloses a hydrogen engine cylinder cover which comprises a cylinder cover body, a plurality of air inlet channels communicated with cylinder holes are formed in one side of the cylinder cover body, and air pipe flanges connected with air inlet manifolds are correspondingly arranged at air channel inlets of the air inlet channels. Spray head insertion holes for mounting hydrogen spray nozzles are formed in the bottoms of the end surfaces of the plurality of gas pipe flanges; and the spray head insertion holes obliquely extend to the cavity wall of the gas inlet channel from the gas pipe flanges. According to the hydrogen engine cylinder cover, the technical field of air inlet of the cylinder cover is achieved, the spray head insertion hole of the hydrogen spray nozzle is formed below the air channel inlet, the spray head insertion hole obliquely extends upwards into the air inlet channel, on one hand, mixing uniformity is compatible, on the other hand, backflow, tempering and leakage of hydroge
