The fuel gas distribution device can guarantee evenness of work load of each cylinder, thereby improving the operating reliability of an engine.
Description
Technical field
The utility model relates to a kind of gas engine technical field, relates in particular to a kind of suction tude of gas engine.
Background technique
Gas engine by transport combination gas in cylinder, does reciprocating linear motion in cylinder by piston when work then, produces stronger suction, thereby combination gas is burnt in suction tude sucks cylinder.Gas engine is when work, for a short time, load that the size of the combination gas quality of each cylinder of inspiration is easy to generate inhomogeneous during rated load, cause each cylinder operation load inhomogeneous, it is too high to be easy to generate excessive generation mechanical load of individual cylinder power and heat load, and then cause piston scraping, produce bigger accident, influence the gas engine reliability of operation.
As claimant of the present utility model, be devoted for years to production and manufacturing in gas engine and diesel engine, have rich practice experience.Through concentrating on studies, creatively overcome above-mentioned technological deficiency.
The model utility content
Technical problem to be solved in the utility model provides a kind of suction tude with the combination gas distribution function, has guaranteed the uniformity of each cylinder operation load, has improved the motor reliability of operation.
For solving the problems of the technologies described above, the technical solution of the utility model is: the suction tude of band combination gas distribution function comprises: the intake manifold; At least two air intake branches, described air intake branch is arranged on the intake manifold, and described air intake branch is connected with the intake manifold and forms independently first cavity; Also comprise gas distribution device, be used for combination gas is evenly distributed to each air intake branch that described gas distribution device is arranged in first cavity.
Described gas distribution device comprises and is used to form the independently gas distribution pipe of second cavity, described gas distribution pipe is arranged in intake manifold's the tube chamber, and described gas distribution pipe is provided with suction port and a plurality of combustion gas dispensing orifice that is used for first cavity and the connection of second cavity.
Described suction port is arranged on the axial end portion of described gas distribution pipe.
Described suction port is along the radially setting of gas distribution pipe, and stretches out described intake manifold's outside.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: what form by being connected at intake manifold and air intake branch independently is provided with gas distribution device in first cavity, can enter each cylinder again with being assigned to uniformly in each air intake branch through combination gas.Because gas distribution device is one and is used to form the independently gas distribution pipe of second cavity, and gas distribution pipe is provided with suction port and a plurality of combustion gas dispensing orifice, a plurality of combustion gas dispensing orifices can be connected first cavity and second cavity, characteristic according to motor, according to fluid mechanics principle, the quantity that can specific design goes out the combustion gas dispensing orifice, size and position, the pressure field that enters the combination gas in first cavity is evenly distributed, thereby make combination gas enter into each cylinder equably, guarantee each cylinder operation load evenly, improve the motor reliability of operation, and air and combustion gas are further mixed when entering the intake manifold after gas distribution pipe is discharged by a plurality of combustion gas dispensing orifices, energy-conservation environmental protection is again fully burnt in the assurance combination gas.
Description of drawings
Fig. 1 is the utility model embodiment one a structure sectional view;
Fig. 2 is the utility model embodiment two a structure sectional view;
Among the figure: 1: the intake manifold; 2: air intake branch; 3: gas distribution pipe; 4: suction port; 5: the combustion gas dispensing orifice; 6: the first cavitys; 7: the suction port flange; 8: the second cavitys; 9: blanking cover.
Embodiment
Embodiment one:
As shown in Figure 1, the suction tude of band combination gas distribution function, comprise intake manifold 1, on intake manifold 1, be provided with at least two air intake branches 2, described air intake branch 2 is connected with intake manifold 1 and forms independently first cavity 6, wherein, determine the quantity of air intake branch 2 according to the number of cylinder, it is indoor by air intake branch 2 engine combustion to be sent in combination gas.
A gas distribution pipe 3 also is installed in first cavity 6, gas distribution pipe 3 is arranged in intake manifold 1 the tube chamber, an axial end portion of gas distribution pipe 3 forms independently second cavity 8 by blanking cover 9 sealing or the inwall by intake manifold 1 with mouth of pipe sealing, another axial end portion is a suction port 4, on suction port 4, can be provided with suction port flange 7, gas distribution pipe 3 is fixedly installed togather by suction port flange 7 with intake manifold 1, suction port flange 7 is connected with the pipeline of combination gas, makes things convenient for entering of combination gas.
On described gas distribution pipe 3, be provided with a plurality of combustion gas dispensing orifices 5, a plurality of combustion gas dispensing orifices 5 can be connected first cavity 6 and second cavity 8, owing to the pressure field of the combination gas in first cavity 6 that enters intake manifold 1 and air intake branch 2 formation is evenly distributed by a plurality of combustion gas dispensing orifices 5, thereby make combination gas enter each cylinder uniformly, make the work of each cylinder even, guarantee each cylinder operation load evenly, improve the motor reliability of operation, and can enter mixing once more in the gas distribution pipe 3, so combustion gas and air are further mixed, make sufficient combustion, energy saving and environmental protection.
Embodiment two:
As shown in Figure 2, its structure and embodiment one are basic identical, difference is: described suction port 4 radially is provided with along gas distribution pipe 3, the two ends mouth of pipe of gas distribution pipe 3 forms second cavity 8 by blanking cover 9 or the inwall by intake manifold 1 with mouth of pipe sealing, suction port 4 stretches out described intake manifold's 1 outside, and this mode can satisfy different structure installation requirements.The utility model is relatively simple for structure, and is easy to processing, low cost of manufacture.
During work, air and combustion gas are introduced in the gas distribution pipe 3 by suction port 4 through after the premixing, enter in first cavity 6 by combustion gas dispensing orifice 5 then, are assigned to uniformly in each air intake branch 2 by first cavity 6, and then enter each cylinder; This mode can make air and combustion gas better mixing when entering intake manifold 1 after gas distribution pipe 3 is discharged, make sufficient combustion, not only energy saving and environmental protection, and according to the characteristic and the needs of motor, calculate quantity, size and the position of combustion gas dispensing orifice 5 by CFD fluid software for calculation, the pressure field of the combination gas in intake manifold 1 and the air intake branch 2 is evenly distributed, thereby make combination gas enter each cylinder uniformly, make the work of each cylinder even, guarantee each cylinder operation load evenly, improve the motor reliability of operation.
