Abstract
The utility model discloses a kind of water-cooled four-valve engine with two separated 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, spaced and share a Carburetor at the air inlet port of air inlet air flue between two air inlet air flues.Motor two intake valve of the present utility model is equipped with the air inlet air flue of unique spacer, 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.
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 two separated 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 two separated air flue is provided, two intake valves of this motor are equipped with the air inlet air flue of unique spacer, 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 two separated 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, spaced and share a Carburetor at the air inlet port of air inlet air flue between two air inlet air flues.
Further, the air inlet port of described two air inlet air flues is that horizontal alignment is arranged.
Further, described Carburetor is provided with the horizontal movable type plunger closing or open air inlet air flue, and this horizontal movable type plunger closes moving horizontally 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 equipped with the air inlet air flue of unique spacer, 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.
Embodiment
As shown in Figure 3,4, the water-cooled four-valve engine with two separated 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 spaced between air inlet air flue 32, two air inlet air flue 31,32 and air inlet air flue air inlet port share a Carburetor 2.
Further, the air inlet port of described two air inlet air flues 31,32 is that horizontal alignment is arranged; Described Carburetor 2 is provided with the horizontal movable type plunger 21 closing or open air inlet air flue, and this horizontal movable type plunger 21 closes moving horizontally process choosing or open the air inlet port of two air inlet air flues 31,32.
Working principle of the present utility model is as described below: when the engine operates with a low speed, the horizontal movable type plunger 21 controlling Carburetor 2 is positioned at two air inlet air flues 31, in the middle of the air inlet port of 32, thus close an air inlet air flue 31, only open another air inlet air flue 32, because the cross section of single air inlet air flue 32 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.
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.
