Description

A kind of motor

Technical field

The present invention relates to a kind of motor, relate in particular to a kind of intake manifold structure that is applicable on the vehicular engine.

Background technique

Vehicular engine exists intake manifold length to cooperate the bad problem of situation with engine speed at present, makes the performance of motor not give full play to.

The Inlet Manifold Design oil consumption of conventional engines is higher, and the gas exhaust manifold size is also bigger.Air inlet resonance when the intake manifold of fixed length can't be taken into account different rotating speeds, therefore, motor can only be selected the intake manifold of a compromise length, and this just makes the power character of motor relatively poor, fuel consumption rate is higher, thereby it is also bigger to cause motor vehicle exhaust emission to pollute.

Summary of the invention

In view of the above problems, the invention provides a kind of motor.

In order to achieve the above object, the present invention has adopted following technological scheme: a kind of motor, it mainly comprises crankcase, intake manifold, is arranged at the valve in this intake manifold outlet port, cylinder head and cylinder head cover, wherein, this intake manifold comprises body, and this body air intake links to each other with air-inlet cavity, and the air outlet is connected with the engine cylinder suction port, this body comprises at least two suction tude, and adjacent two suction tude are pegged graft mutually and are one.

Preferable, the invention provides a kind of motor, wherein, the splicing position of described adjacent two suction tude is arranged with seal ring, wherein is connected with on the suction tude can drive to be adjacent to connect the suction tude of establishing mobile driving structure within it.

Preferable, the invention provides a kind of motor, wherein, described driving structure be driven by motor bar linkage structure, chain transmission structure, hydro cylinder or automobile driving mechanism one of them.

Preferable, the invention provides a kind of motor, wherein, described valve is in order to close the variable tracheae exit butterfly valve of one of them suction tude.

Compared to prior art, the invention provides a kind of motor, not only can utilize valve control to close one of them suction tude, accelerate rate of burning, improved exhaust gas recirculation (EGR) rate, and make motor pass through the intake manifold realization air inflow of adjustable length and the coupling of engine speed, improve the power character of motor effectively.

Description of drawings:

Fig. 1 is adjusted to the schematic representation of minimum length for intake manifold of the present invention;

Fig. 2 is adjusted to the schematic representation of extreme length for intake manifold of the present invention;

Fig. 3 is for arranging the schematic representation of valve in intake manifold.

Embodiment

Please refer to Fig. 1 to shown in Figure 3, the invention provides a kind of motor, not only can utilize valve 10 controls to close one of them suction tude, accelerate rate of burning, improved exhaust gas recirculation (EGR) rate, and make motor pass through the intake manifold realization air inflow of adjustable length and the coupling of engine speed, improve the power character of motor effectively.

Wherein, described motor mainly comprises crankcase, intake manifold, cylinder head and cylinder head cover, and is not shown in the figures, for motor basic structure, is not described in detail in this.

Again, this intake manifold comprises body, and this body air intake links to each other with air-inlet cavity 1, the air outlet is connected with engine cylinder suction port 2, and this body comprises at least two suction tude, in present embodiment, be example with two suction tude, this two suction tude is respectively first suction tude 3 and second suction tude 4.

Wherein, this first suction tude 3 and the 4 adjacent and mutual grafting of second suction tude are one, and the splicing position of described first suction tude 3 and second suction tude 4 is arranged with seal ring 9, to improve the sealing between the two adjacent suction tude, prevent that gas from leaking.

Moreover, also be connected with driving structure 7 on this first suction tude 3, this driving structure 7 can drive with this first suction tude 3 adjacent second suction tude 4 of establishing and move around in this first suction tude 3, wherein, the pipe diameter of this first suction tude 3 is little than the pipe diameter of second suction tude 4, to make this first suction tude 3 in this second suction tude 4, move around, please refer to Figure 1 and Figure 2, be respectively intake manifold and be adjusted to the schematic representation of minimum length and extreme length, when driving the driving structure that is connected with this first suction tude 3, making these first suction tude, 3 dextrorotations go to this first suction tude 3 moves in this second suction tude 4 fully, this intake manifold is adjusted to minimum length, as shown in Figure 1, when driving the driving structure that is connected with this first suction tude 3, make this first suction tude 3 be rotated counterclockwise outside this first suction tude 3 shifts out this second suction tude 4 fully, only one of this first suction tude 3 end is established with a terminal phase mutual connection of this second suction tude 4, then at this moment, this intake manifold is adjusted to extreme length, as shown in Figure 2, described driving structure 7 can adopt the driven by motor bar linkage structure, the chain transmission structure, the driving mechanism of hydro cylinder or automobile is realized, this is general knowledge known in this field, is not described in detail in this.

Moreover, when air inlet, gas at first enters air-inlet cavity 1, body through intake manifold enters cylinder by engine cylinder cap suction port 2, utilize the driving structure 7 that is connected setting with this first suction tude 3, drive and the movement this first suction tude 3 in of these first suction tude, 3 adjacent second suction tude 4 of establishing, with the body length according to the rotational speed regulation intake manifold of motor.

Because the intake manifold body of shorter length can reduce intake resistance, increase gas flow rate, air inflow is more, and engine speed needs intake velocity to accelerate and could adapt to when very fast.

In like manner, the intake manifold body of length, intake resistance is bigger, and gas flow rate is also corresponding slower, and air inflow is less, and it is slower to adapt to engine speed, when intake velocity slows down.

Therefore, by adjusting the length of intake manifold body, the rotating speed of itself and motor is adapted, when engine speed is fast or slow, utilize driving structure 7 adjustment to make the length of intake manifold body, make the air inflow of cylinder reach optimum efficiency, realize the coupling of air inflow and engine speed, thereby improve the power character of motor when any rotating speed.

Please refer to shown in Figure 3 again, described valve 10 is arranged at this intake manifold outlet port, and this valve 10 can be set to variable tracheae exit butterfly valve, can close one of them suction tude by this variable tracheae exit butterfly valve, as shown in Figure 3, after this valve 10 was closed suction tude B, single suction tude A was when air inlet, because asymmetry, gas forms eddy current in cylinder, thereby it is more stable to burn, and has accelerated rate of burning, has improved exhaust gas recirculation (EGR) rate.
