Abstract
The utility model provides a kind of air valve structure of Diesel engine, including air inlet and gas outlet, and the air inlet side is equipped with chamfering.After air inlet is provided with eccentric chamfer so that air-flow produces vortex rotation, but does not change flow.Therefore, air valve structure described in the utility model not only ensure that air flow rate, moreover it is possible to so that the air-flow entered from air inlet produces vortex rotation so that air-flow can be fully burned in cylinder, effectively improve fuel efficiency, so that engine power is stronger.
Description
Technical field
The utility model is related to technical field of engines, especially a kind of air valve structure of Diesel engine.
Background technology
Valve is one of strength member of engine.Need to bear higher mechanical load and thermic load, air inlet during work
Erosion of the door due to being often subject to high-temperature fuel gas, it is easy to produce gas leakage, corrosion or even damage.General inlet valve by valve disc and
Valve stem two parts are constituted.Valve disc has platybasic type, sunken bottom type, depressed center etc., and current platybasic type valve is most widely used, its
Advantage is that geometry is simple, and good manufacturability, heating surface area is small, and inlet and exhaust valve can be used.Such as Publication No. CN204827574
Chinese patent disclose a kind of diesel engine spiracle, the bottom surface of its valve disc is plane, and body portion is three-level pie structure, and bottom surface is
Plane, this air valve structure is simple, is easy to manufacture, and endotherm area is small, is not easily susceptible to high-temperature fuel gas erosion.Three-level pie structure
Valve disc body portion, valve is big by end face, and intake resistance is small, sealing and thermal conductivity it is further preferred that.The valve of plane only realize into
Fuel-displaced effect, can not improve abundant burning of the fuel oil in cylinder, accordingly, it would be desirable to a kind of air valve structure of modern.
Utility model content
The purpose of this utility model is to use planar structure to solve traditional diesel engine spiracle, is only realized into fuel-displaced
Basic function, it is impossible to improve clean-burning problem of the fuel oil in cylinder.
In order to solve problem above, the utility model provides a kind of air valve structure of Diesel engine, including air inlet
And gas outlet, the air inlet side is equipped with chamfering.After air inlet is provided with eccentric chamfer so that air-flow produces vortex rotation
Turn, but do not change flow.Therefore, air valve structure described in the utility model not only ensure that air flow rate, moreover it is possible to so that from entering
The air-flow that gas port enters produces vortex rotation so that air-flow can be fully burned in cylinder, effectively improve fuel efficiency, so that
Make engine power stronger.
Preferably, the diameter of the chamfering is bigger than the diameter of air inlet and is cut in air inlet outside, the chamfering is from cutting
Point becomes larger to both sides.Air inlet is cut in outside chamfering, and shape becomes larger, and could so cause air-flow is produced sufficiently large
Vortex rotation, promotes air-flow fully to be burnt in cylinder.
Preferably, the chamfering diameter 3.7-4.8mm bigger than air inlet diameter.
Preferably, the direction of two air inlet chamferings of same cylinder differs 75-85 °.Two air inlets of same cylinder fall
There is 75-85 ° of difference in angular direction, can make it that the vortex direction for entering cylinder interior air-flow is different, further promote the abundant combustion of air-flow
Burn, effect is more preferable.
The utility model is through using proof, effect is preferable, simple and practical.
Brief description of the drawings
Accompanying drawing 1 is the air valve structure schematic diagram of Diesel engine described in the utility model.
1st, air inlet；2nd, gas outlet；3rd, chamfering.
Embodiment
A kind of air valve structure of Diesel engine of the utility model is described further below in conjunction with the accompanying drawings.
As shown in fig. 1, the utility model provides a kind of air valve structure of Diesel engine, including air inlet 1 and goes out
Gas port 2, the side of air inlet 1 is equipped with chamfering 3.The diameter of the chamfering 3 than air inlet 1 the big 3.7-4.8mm of diameter and
Air inlet 1 is cut in outside, the chamfering 3 becomes larger from point of contact to both sides.Air inlet 1 is cut in outside chamfering 3, and shape gradually becomes
Greatly, it could so cause air-flow to produce sufficiently large vortex rotation, promote air-flow fully to be burnt in cylinder.
The direction of the chamfering 3 of two air inlets 1 of same cylinder differs 75-85 °.Two directions of 1 chamfering of air inlet 3 of same cylinder
There is 75-85 ° of difference, can make it that the vortex direction for entering cylinder interior air-flow is different, further promote the abundant burning of air-flow, effect
More preferably.
After air inlet 1 is provided with eccentric chamfer 3 so that air-flow produces vortex rotation, but does not change flow.Therefore, originally
Air valve structure described in utility model not only ensure that air flow rate, moreover it is possible to so that the air-flow entered from air inlet 1 produces vortex
Rotation so that air-flow can be fully burned in cylinder, effectively improve fuel efficiency, so that engine power is stronger.
The utility model is through using proof, effect is preferable, simple and practical.
The utility model is not limited to above example and conversion.
