Abstract
The utility model provides an engine lubricating oil outer circulatory system. The engine lubricating oil outer circulatory system comprises a cylinder body and a main oil gallery arranged inside the cylinder body. An electronic high pressure engine oil pump arranged on the upper portion of an oil pan is connected with the main oil gallery through an engine oil filter. An oil storage tank is arranged outside the cylinder body, an oil outlet arranged on the lower portion of the side wall of the oil pan is connected with an upper portion oil inlet arranged in the oil storage tank through pipelines and an electronic low pressure engine oil pump. A lower portion oil outlet arranged in the oil storage tank is connected with the electronic high pressure engine oil pump arranged on the upper portion of the oil pan through pipelines. A drainage port is arranged on the upper portion of the oil storage tank. The drainage port is connected with an oil return opening arranged in the oil pan through pipelines. The oil return opening arranged on the oil pan is placed at a position lower than the drainage port. After flowing out from everywhere of the engine, the lubricating oil returns to the oil pan through the main oil gallery arranged inside the cylinder block, and then is pumped into the oil storage tank through the electronic low pressure engine oil pump. The lubricating oil in the oil storage tank is pumped into the main oil gallery through the electronic high pressure engine oil pump. After flowing through the engine oil filter, the lubricating oil reaches everywhere needing lubricating, so that a lubricating oil outer circulatory loop is formed.
Description
Technical field
The utility model relates to a kind of engine lubricating oil external circulating system, belongs to car engine lubrication system.
Background technique
At present motor miniaturization is to need significantly to reduce on trend, the especially short transverse.The height of oil sump has occupied cylinder body part height, reduces this requirement of motor height in order to adapt to, and is convenient to engine arrangement, reduces the height of motor, and the height that reduces oil sump is imperative.After reducing the height of oil sump, the problem that how to solve car engine lubrication system is mentioned agenda.
Summary of the invention
Main purpose of the present utility model is for above-mentioned situation, designs a kind of engine lubricating oil external circulating system.
The technical solution of the utility model: engine lubricating oil external circulating system of the present utility model comprises cylinder body, main oil gallery in the cylinder body, being positioned at the outer electronic high voltage oil pump of cylinder body is connected with main oil gallery by oil filter, the utility model is at cylinder body peripheral hardware oil storage tank, and the oil sump lower sidewall has oil outlet to be connected to the top filler opening of oil storage tank by pipeline and electronics low-pressure oil pump; The bottom oil outlet of oil storage tank is connected to by pipeline and is positioned at the outer electronic high voltage oil pump of cylinder body; Drain tap is established on top at oil storage tank, and drain tap is connected to return opening on the oil sump by pipeline, and the oil outlet on the oil sump is lower than return opening.
The volume of described oil storage tank is 2～4 liters, and the height of oil storage tank is 20～50cm.
The filler opening of described oil storage tank exceeds 15～40cm than oil outlet.
Oil filler is established at the top of described oil storage tank, and cap is arranged on the oil filler.
Drain tap on the described oil storage tank exceeds 5～45cm than the return opening on the oil sump.
Return opening on the described oil sump exceeds 5～10cm than oil outlet.
The filler opening of described oil storage tank and drain tap are a level height.
Advantage of the present utility model: 1, the utility model can significantly reduce the oil sump height, even the cancellation oil sump directly seals lower cylinder body, thereby reduces motor complete machine height, is convenient to arrange motor, for vehicle modeling etc. is all provided convenience.
2, because the existence of liquid container, motor is which kind of angle no matter, and the electronic high voltage oil pump can both be drawn onto oil, therefore can suitably reduce the machine oil adding amount, need not the liquid level of checking up Engine oil.
3, because liquid container and the isolation of crankcase gas blowby are conducive to reduce the machine oil air content, guarantee greasy property.
4, because oil sump inner engine oil amount is limited, can avoid bent axle to stir machine oil, reduce engine power loss, reduce simultaneously the machine oil content in the crankcase gas blowby, reduce the engine motor oil consumption.
5, the utility model has adopted the electronic machine oil pump, with respect to traditional mechanical oil pump, be set up very large flexibility at cloth, and energy consumption is lower in theory.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model: engine lubricating oil external circulating system of the present utility model comprises cylinder body 1, main oil gallery 3 in the cylinder body 1, being positioned at cylinder body 1 outer electronic high voltage oil pump 4 is connected with main oil gallery 3 by oil filter 5, at cylinder body 1 peripheral hardware oil storage tank 6, oil sump 2 lower sidewall have oil outlet 2a to be connected to the top filler opening 6a of oil storage tank 6 by pipeline and electronics low-pressure oil pump 7; The bottom oil outlet 6b of oil storage tank 6 is connected to the electronic high voltage oil pump 4 that is positioned at outside the cylinder body 1 by pipeline; Establish drain tap 6c on the top of oil storage tank 6, drain tap 6c is connected to return opening 2b on the oil sump 2 by pipeline, and the oil outlet 2a on the oil sump 2 is lower than return opening 2b, and the return opening 2b on the oil sump 2 is lower than the drain tap 6c on the oil storage tank.
The volume of described oil storage tank 6 is 2～4 liters, and the height of oil storage tank 6 is 20～50cm.
The filler opening 6a of described oil storage tank 6 exceeds 15～40cm than oil outlet 6b.
Oil filler is established at the top of described oil storage tank 6, and cap 6d is arranged on the oil filler.
Drain tap 6c on the described oil storage tank exceeds 5～45cm than the return opening 2b on the oil sump 2.
Return opening 2b on the described oil sump 2 exceeds 5～10cm than oil outlet 2a.
The filler opening 6a of described oil storage tank 6 and drain tap 6c are a level height.
Working principle: lubricant oil by body in main oil gallery 3 is got back to oil sump 2 after flowing out from motor everywhere, is pumped in the oil storage tank 6 through filler opening 6a by electronics low-pressure oil pump 7 afterwards; The bottom oil outlet 6b of oil storage tank 6 is connected with electronic high voltage oil pump 4, and the lubricant oil in the oil storage tank pumps into main oil gallery by electronic high voltage oil pump 4, and after oil filter 5, arriving needs to lubricate everywhere, thereby forms a lubrication oil circulation loop.
