Internal direct injection cylinder cover for methanol engine

According to the internal direct injection cylinder cover for the methanol engine, the internal direct injection cylinder cover is applied to the technical field of engines, gaps between oil nozzles and a mounting groove are sealed through laser welding, fuel leakage is effectively avoided, the two oil nozzles are adopted to achieve direct injection towards the interior of a cylinder, the fuel injected by the oil nozzles is fully mixed with mixed gas, and the fuel injection efficiency is improved. Compared with traditional out-cylinder injection, in-cylinder direct injection can inject the fuel into the combustion chamber in the intake stroke period of the engine without loss of the fuel through an intake pipe, so that a uniform combustion mixture is formed, the combustion heat efficiency is further improved, in addition, the entering fuel can be cooled by adopting the cooling cavity, and the combustion efficiency is improved. In addition, the magnetic liquid enters the elastic movable layer under the action
