The first passage portion 19 that 5 connecting pin of oil rectifier communicates, the connecting tube 16 are metal knitted pipe.
The operation principle of the system is：Dry sump 1 accepts the machine oil of engine crankcase drippage, and lubricating oil pump 2 passes through
Its internal lobe pump inhales the air inside machine oil and engine crankcase that dry sump 1 is accepted by connecting tube 16
Enter, machine oil and air are entered the machine oil with Oil-gas Separation function by the lobe pump in lubricating oil pump 2 together by connecting tube 16 again
In tank 3, machine oil and air carry out Oil-gas Separation in the machine oil tank 3 with Oil-gas Separation function, in pipe column type spiral separator
Under the action of 14, wall is hit in 3 inner cavity of machine oil tank using machine oil itself kinetic energy and generate larger centrifugal force, machine oil will be attached at
Outlet 15 is fallen on one cylinder 12 and separator 14 and gradually under the effect of gravity, since density kinetic energy is different, machine oil tank 3
The machine oil centrifuged on inner cavity just separates the air being mingled with, and because atmospheric density is lighter, forms internal helicoid upper up-flow, slave
3 top discharge of oil tank, and machine oil gradually falls on 3 inner cavity wall surface of machine oil tank, Oil-gas Separation process also completes, lubricating oil pump 2
In impeller pump the machine oil of preliminary Oil-gas Separation is sucked wherein by connecting tube 16, then by the impeller pump of lubricating oil pump 2 by machine
Oil enters in oily shank body 4, and machine oil is led to using after 5 filtering of oil filter by the first of oily shank body 4 after entering oily shank body
Road portion 19 enters engine interior oil circuit.
Due to provided with the pipe column type cyclone separator 14 with oil gas separation inside machine oil tank 3, can divide
Machine oil from the lobe pump air entrainment from lubricating oil pump 2, compared with the machine oil tank 3 of not oil gas separation, machine oil tank 3 pushes up
The air engine oil content that portion comes out is almost O, and oil gas separation is notable.Therefore, the bubble level for reducing machine oil, carries
High machine oil use quality, and reduce the consumption of machine oil, and then improve the lubricant effect of engine.Due to being moved using primary
Installation site of 5 position of machine oil filter as oil circuit oil shank body 4 inside and outside 1 lubricating system of dry sump, reduces small-sized
Racing car wet type lubrication changes modification degree of the dry lubrication system to engine, reduces improvement cost and difficulty, facilitates dry type
Application of 1 lubricating system of oil sump in kart.Because there are two the first cavitys 6 for the tool of dry sump 1, can drop in this way
Shaking amplitude of the low machine oil in dry sump 1, while the slope of the first cavity 6 gives machine oil and flow to outlet naturally
Place, the machine oil for accelerating crankcase drippage flow to the speed of lubricating oil pump 2 from dry sump 1, improve engine lubrication system
Efficiency, for oil temperature also often in optimum working temperature, dry sump 1 significantly reduces engine in racing car
Mounting height, the weight of a whole set of lubricating system can be alleviated, reduce the mounting height of engine, possessed lower heavy
The heart, lighter weight, and then possess better handling.Therefore, the machine oil for being located at dry sump 1 can faster more uniformly
It is extracted, to improve engine lubrication system working efficiency.The machine oil tank 3 that Oil-gas Separation function is carried due to devising, because
This, can preferably detach machine oil and air from dry sump 1, eliminate the case where machine oil is with air escape, reduce
The consumption of machine oil, and the bubble level of machine oil is reduced, engine lubrication performance is improved, and then improve the use longevity of engine
Life；Due to devising oily shank body 4, the outer oil circuit and hair that are driven lubricating oil pump 2 using the position of former monomotor oil filter 5
Motivation internal oil passages are connected, and reduce kart engine wet type lubrication and change dry lubrication system to EM Engine Modification degree,
To simplify 1 system reform step of dry sump on kart, reduce race using 1 system of dry sump at
This, reduces transformation difficulty, facilitates application of 1 lubricating system of dry sump in kart, and further reduced
The total weight of 1 system of dry sump, allows racing car to possess better lightweight and ultimate attainment performance.
