Abstract
The utility model discloses a water -cooling four properties door engine with double helix air flue, including engine (air) intake valve and carburetor, for the air flue that admits air between (air) intake valve and the carburetor, each (air) intake valve correspondence is provided with an independent air flue that admits air, and two admit air between the air flue each other, and come in the spiral interval and at two intake port sharing carburetors that admit air the air flue. The utility model discloses a two (air) intake valves in the engine are equipped with the independent spiral spaced air flue that admits air, and the optional seals one of them air flue that admits air when low -speed operation, and then guarantee gaseously in another air flue that admits air have a very fast velocity of flow to guarantee to form a small -size gaseous swirl after the mist gets into the combustion chamber, and then improve the mixed effect of mist, improve the conbustion ratio of mist, improve the low -speed operation performance of engine.
Description
Technical field
The utility model relates to a kind of water-cooled four-valve engine, belongs to engine apparatus technical field, refers in particular to a kind of water-cooled four-valve engine with double helix air flue.
Background technique
As illustrated in fig. 1 and 2, at present, the air inlet air flue 5 for sharing between two intake valves 11,12 of existing water-cooled four-valve engine and Carburetor 2, and also Carburetor 2 adopts vertical transport plunger 22.The cross section of this shared air inlet air flue 5 is larger, the air flue that relative cross-section is less, under certain Throughput situation, gas in the air inlet air flue that cross section is larger can be slack-off by flow velocity, cause causing mixed gas to mix because pressure of inspiration(Pi) is lower when time of engine low speed abundant not, mixed gas is bad in engine combustion Indoor Combustion effect, and then causes time of engine low speed performance bad, and the power of motor and moment of torsion are all far below original desired effects.
Model utility content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, a kind of water-cooled four-valve engine with double helix air flue is provided, two intake valves of this motor are provided with the air inlet air flue at independent spiral interval, can select when low-speed running to close a wherein air inlet air flue, and then ensure that in another air inlet air flue, gas has flow velocity faster, thus improve the mixed effect of mixed gas, promote the low-speed running performance of motor.
To achieve these goals, the utility model realizes according to following technological scheme:
A kind of water-cooled four-valve engine with double helix air flue, include engine intake valve and Carburetor, it is air inlet air flue between intake valve and Carburetor, each intake valve correspondence described is provided with an independently air inlet air flue, and between two air inlet air flues, mutual spiral spacer comes and shares a Carburetor at the air inlet port of two air inlet air flues.
Further, the air inlet port of described two air inlet air flues is for be vertically arranged in juxtaposition up and down.
Further, the airway length of air inlet air flue that described air inlet port is positioned at below is greater than the airway length that air inlet port is positioned at the air inlet air flue of top.
Further, described Carburetor is provided with the vertical transport plunger closing or open air inlet air flue, and this vertical transport plunger closes moving up and down process choosing or open the air inlet port of two air inlet air flues.
Compared with prior art, its beneficial effect is the utility model:
Motor two intake valve of the present utility model is provided with the air inlet air flue at independent spiral interval, can select when low-speed running to close a wherein air inlet air flue, and then ensure that in another air inlet air flue, gas has flow velocity faster, thus ensure can form a small gas whirlpool after mixed gas enters firing chamber, and then improve the mixed effect of mixed gas, improve the rate of combustion of mixed gas, improve the low-speed running performance of motor.
In order to the utility model can be understood more clearly, illustrate below with reference to accompanying drawing and set forth embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of prior art.
Fig. 2 is the plan structure schematic diagram of prior art.
Fig. 3 is Facad structure schematic diagram of the present utility model.
Fig. 4 is plan structure schematic diagram of the present utility model.
Fig. 5 is the rough schematic of double helix air flue of the present utility model.
Embodiment
As Fig. 3,4, shown in, the water-cooled four-valve engine with double helix air flue described in the utility model, include engine intake valve 11,12 and Carburetor 2, it is air inlet air flue 31,32 between intake valve 11,12 and Carburetor 2, intake valve 11 correspondence independently air inlet air flue 31, intake valve 12 correspondence independently between air inlet air flue 32, two air inlet air flue 31,32 mutual spiral spacer come and two air inlet air flues air inlet port share a Carburetor 2.
Further, the air inlet port of described two air inlet air flues 31,32 is for be vertically arranged in juxtaposition up and down, and the airway length that air inlet port is positioned at the air inlet air flue 31 of below is greater than the airway length that air inlet port is positioned at the air inlet air flue 32 of top.
Further, described Carburetor 2 is provided with the vertical transport plunger 21 closing or open air inlet air flue, and this vertical transport plunger 21 closes moving up and down process choosing or open the air inlet port of two air inlet air flues.
Working principle of the present utility model is as described below:
When the engine operates with a low speed, the vertical transport plunger 21 controlling Carburetor 2 is positioned in the middle of the air inlet port of two air inlet air flues, thus close the air inlet port of top, only open the air inlet port of below, because the cross section of single air inlet air flue 31 is less, mixed gas can enter firing chamber 4 with flow velocity faster, such mixed gas can form a small-sized gas swirl after entering firing chamber 4, thus greatly improve the composite rate of mixed gas, improve the rate of combustion of mixed gas, thus improve the low-speed running performance of motor;
When the aperture of vertical transport plunger 21 is greater than half or the standard-sized sheet of full-gear, the air inlet air flue 31 that a mixed gas part is positioned at below by air inlet port enters firing chamber, the air inlet air flue 32 that mixed gas another part is positioned at top by air inlet port enters firing chamber, the airway length being positioned at the air inlet air flue 31 of below due to air inlet port is greater than the airway length that air inlet port is positioned at the air inlet air flue 32 of top, therefore there is speed the time that mixed gas enters firing chamber 4 by two air inlet air flues, thus a new gas swirl after making mixed gas enter firing chamber 4, can be formed, make mixed gas Thorough combustion equally, promote the combustion efficiency of mixed gas.
The utility model is not limited to above-mentioned mode of execution, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, if these are changed and modification belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
