Abstract

The invention belongs to the technical field of engines, and provides an engine oil filter and an engine with the same. The engine oil is stored in the oil pan, and most of the oil is stored in the deep and shallow cavities of the engine oil pan. Therefore, when the liquid level of the oil pan changes, how to quickly switch the functioning filter is the key. The present invention proposes The second filter unit is added on the basis of the first filter unit. When the oil volume is reduced, the oil suction plate of the second filter unit moves down with the liquid level under the action of the buoyancy member. There is a magnetic piece directly below the first filter unit. When the oil suction plate and the magnetic piece reach a certain distance, under the action of the magnetic force, the oil suction plate and the first filter cover are fitted to seal the connection hole, so that the first filter unit is here. If the oil cannot be sucked, the second filter unit starts to function at this time, sucking the oil in the shallow cavity to the inside of the engine for lubrication and cooling.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to an oil collecting filter. The invention also relates to a diesel engine. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] If the engine is tilted for a long time, especially if the front and rear are tilted at a large angle, the oil filter may have the problem of air suction. Aiming at the problem of engine oil suction when the engine is tilted, the cost of the two-stage oil pump currently in use in a large area is relatively high. If the oil cannot return to the deep area for a long time, the filter still has the problem of air suction, so the angle of inclination used by the above technology has certain limitations, especially for long-term inclination and the deep area of ​​the oil pan is shallow or Smaller structures are difficult to meet the requi...
