Abstract

The invention belongs to the technical field of engines, and provides an engine oil suction filter and an engine with the same. Engine oil is stored in an oil pan, most of the engine oil is stored in a deep cavity and a shallow cavity of the engine oil pan, and therefore when the liquid level of the oil pan changes, how to rapidly switch the acting suction filter is the key point. According to the engine oil suction filter, a second suction filtration unit is additionally arranged on the basis of a first suction filtration unit, and under the condition that the oil amount is decreased, an oil suction disc of the second suction filtration unit moves downwards along with the liquid level under the effect of a buoyancy part; magnetic parts are arranged under the first suction filtration unit, and after the oil suction disc and the magnetic parts reach a certain distance, the oil suction disc and a first filtering cover are attached to seal a connecting hole under the effect of magnetic force, and therefore the first suction filtration unit cannot suck oil at the position; and at the moment, the second suction filtration unit starts to play a role to suck the engine oil in the shallow cavity into 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...
