Abstract
The invention relates to a manifold type air inlet pipe, which is characterized by consisting of a pressure stabilizing cavity and air inlet manifolds, wherein the pressure stabilizing cavity is arranged in the middle part of the air inlet pipe, the middle part of the upper end of the pressure stabilizing cavity is provided with an air inlet, the air inlet manifolds are uniformly distributed at one side of the pressure stabilizing cavity near an engine air cylinder cover. The manifold type air inlet pipe can ensure the air inlet pressure to be stable, the air inlet pulsation is eliminated, and the air inlet uniformity of each cylinder is ensured. Through the scheme that the air inlet is positioned in the middle part of the pressure stabilizing cavity, the flowing uniformity and stability of the air can be ensured.
Description
Technical field
The invention belongs to the technical field of natural gas engine suction tude, particularly the manifold-type suction tude.
Background technique
Present natural gas engine exploitation, normally basic machine directly adopts diesel engine to design and develop, so the whole case structure of the most of employing of intake manifold, because the diesel combustion mode is an Incylinder direct injection, the premixing before need not burning.And the burning form of natural gas engine to be rock gas need carry out premixing with fresh air in intake duct, so it requires highly to charging efficiency and each cylinder distributing uniformity, box suction tude can not satisfy the requirement of natural gas engine to air inlet fully.
Summary of the invention
The object of the invention provides a kind of manifold-type intake manifold.
Technological scheme of the present invention is achieved in that
The manifold-type suction tude is characterized by: it is made up of pressure stabilizing cavity and intake manifold, and pressure stabilizing cavity is at the middle part of suction tude, and the pressure stabilizing cavity upper center has suction port, and intake manifold is distributed on pressure stabilizing cavity near engine cylinder cap one side.
The present invention can guarantee the stable of suction pressure, eliminates charge pulsation, guarantees that each cylinder air inlet is even.The design proposal that suction port is positioned at pressure stabilizing cavity middle part can guarantee the uniformity and the stability of air flow.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a band rock gas honeycomb duct sectional arrangement drawing of the present invention.
Fig. 3 is a plan view of the present invention.
Fig. 4 is a gas flow analysis chart in the spiral intake manifold of the present invention.
Embodiment
Specify specific embodiments of the present invention below in conjunction with accompanying drawing.
The manifold-type suction tude is characterized by: it is made up of pressure stabilizing cavity 4 and intake manifold 5, and pressure stabilizing cavity 4 is at the middle part of suction tude 1, and pressure stabilizing cavity 4 upper center have suction port 6, and intake manifold 5 is distributed on pressure stabilizing cavity 4 near engine cylinder cap one side.
The manifold-type suction tude, it is shaped as cuboid band seamed edge rounding structure described pressure stabilizing cavity 4.
The manifold-type suction tude is equipped with rock gas honeycomb duct 3 in the described intake manifold 5, and multi-functional sleeve pipe 2 is fitted in the upper end of intake manifold 5.Rock gas honeycomb duct 3 is fitted on the intake manifold 1 with multi-functional sleeve pipe 2, has both helped the assembly process process of gas rail, also can effectively reduce the leakage rate of rock gas, reduces the pollution to environment.Rock gas directly is ejected into the air inlet of combustion chamber place, can prevents that rock gas from mixing with air too early, guarantee that the combustion gas of blast nozzle ejection can be assigned to each cylinder equably.Guarantee each cylinder distributing uniformity like this, effectively controlled air fuel ratio, reduced cyclical variations.
One in every cylinder independently intake manifold 5 structures has reduced the interference of each cylinder suction pressure and air-flow, improves charging efficiency.
Embodiment:
Illustrated in figures 1 and 2; It is made up of BF6M1013-26E4N pressure stabilizing cavity 4 and intake manifold 5, and characteristics are middle part, band spirally inlet air manifold 5 structures that suction port 6 is positioned at pressure stabilizing cavity 4, and rock gas honeycomb duct 3 is fitted on the intake manifold 5 with multi-functional gland 2; Can effectively control air fuel ratio and each cylinder distributing uniformity; Reduce cyclical variations, improve gas consumption and emission performance, reduce the vibrations of motor.
Shown in Figure 3, pressure stabilizing cavity 4 upper center have suction port 6, can guarantee the uniformity and the stability of air flow.
Shown in Figure 4, each intake manifold 5 adopts sped structure, makes air inlet before getting into intake duct, just produce rotation 7; Like this in intake process; The fresh air of rotation and rock gas get into the firing chamber, strengthen the mixing efficiency of air and rock gas, improve the mixed gas uniformity; Help in-cylinder combustion, reduce specific fuel consumption and improve emission performance.
