The utility model relates to a pre-filtering device of an oil-gas separator of a spray pipe type engine, and relates to the field of engine parts. The pre-filtering shell is transversely arranged, the pre-filtering air inlet pipe is arranged at one end of the pre-filtering shell, the pre-filtering air outlet pipe is arranged at the other end of the pre-filtering shell, the pre-filtering baffle is arranged in the pre-filtering shell, the oil return channel is arranged in the middle of the pre-filtering shell, and the vertical section, from the pre-filtering air inlet pipe to the pre-filtering air outlet pipe, of the pre-filtering shell is gradually increased and then gradually decreased. Compared with the prior art, the oil-gas separator has the advantages that large liquid drops in waste gas can be better reduced through the spray pipe and the shutter structure, and the workload of the oil-gas separator is reduced. 本实用新型涉及一种喷管式发动机油气分离器预滤装置，涉及发动机零部件领域，其包括横向设置的预滤壳体、设于预滤壳体一端的预滤进气管、设于预滤壳体另一端的预滤出气管、设于预滤壳体内的预滤挡板、以及
