Engine oil inflation device for engine oil pump testing device

The invention discloses an engine oil inflation device for an engine oil pump testing device. The engine oil inflation device comprises an air pump (1), an oil tank (6) for supplying oil to an oil inlet of an engine oil pump and an air pipe (2) for communicating the air pump (1) with the oil tank (6), and further comprises a division plate (4), wherein the division plate (4) is provided with a plurality of through holes (7) distributed in the whole division plate (4), and the edge of the division plate (4) is connected to the inner side wall of the oil tank (6) and approaches an introduction port of the air pipe (2). By adopting the engine oil inflation device, the gas content of oil is uniform, and the situations that the gas content at the joint of the air pipe and the oil tank is high and the gas content away from the joint is lower are avoided, so that the engine oil pump can output pressure more stably and the using condition of an engine can be reflected more truthfully.
