Vertical engine oil complete recycling and filtering structure and method for engine crankcase

Abstract

The invention discloses a vertical engine oil complete recycling and filtering structure and method for an engine crankcase. An engine oil filtering tank is vertically mounted in and communicated with the interior of the crankcase, the middle section of the engine oil filtering tank is provided with a gas buffering and recycling cavity, the bottom of the engine oil filtering tank is provided with a liquid-gas inlet and outlet connected to the interior of the crankcase, and a small air outlet is formed in the top of the engine oil filtering tank; and the upper section of the engine oil filtering tank is provided with a filtering chamber, the top of the filtering chamber is provided with a small air outlet, the bottom of the filtering chamber is provided with a perforated partition plate mounted on the inner wall of the engine oil filtering tank, and the engine oil filtering element is placed in the filtering chamber. According to the innovative structure, the integrated design of an engine is optimized on the whole, the recovery rate and recovery quality of engine oil are improved, and therefore the quality of the engine is improved on the whole, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of engine equipment, mainly the technology of oil filtration and recovery, in particular to a complete vertical oil recovery and filtration structure and method for engine crankcases. Background technique [0002] The part of the cylinder block used to install the crankshaft is called the crankcase. In the prior art, the upper crankcase and the cylinder block are cast as one, and the lower crankcase is used to store lubricating oil and close the upper crankcase, so it is also called the oil pan diagram. The oil pan bears little force and is generally made of sheet steel stamping. Its shape depends on the overall layout of the engine and the capacity of oil. [0003] Crankshaft lubrication mainly refers to the lubrication of the bearing pad between the rocker arm and the lubrication of the fixed points at both ends. There will be an oil passage in the middle of the crankshaft that communicates with each bear...

AI Technical Summary

Problems solved by technology

[0004] The existing engine oil does not have a special filter, and it is only cooled and recovered when the exhaust is exhausted. The usual recovery is to use a pipeline to connect it back to the crankcase, so there will be a problem of incomplete oil recovery. On the one hand, it will cause additional engine oil The volume of the pipeline equipment is too large. On the one hand, the engine oil will be discharged into the air to form pollution, and it will also consume the engine oil. Dust will also enter through the exhaust channel, resulting in dirty and less oil.
