Abstract
The utility model belongs to the technical field of automobile motors, and particularly relates to an intake manifold of a motor. The intake manifold of the motor comprises an air collecting chamber and the intake manifold body, and a resonance supercharging mechanism is arranged between the air collecting chamber and the intake manifold body. The resonance supercharging mechanism is composed of a resonance cavity and a resonance air inlet pipe which are communicated. The resonance cavity is communicated with the intake manifold body, and the resonance air inlet pipe is communicated with the air collecting chamber. By adoption of the structure, under a certain rotating speed of the motor, due to gas resonance, caused by periodic movement of a piston, in the intake manifold body, a resonator of Helmholtz is formed. An additional supercharging effect of gas is achieved, intake efficiency of the motor is obviously improved, and dynamic property and economy of the motor are improved.
Description
Technical field
The utility model belongs to the technical field of motor car engine, is specifically related to the intake manifold of motor.
Background technique
At present, the intake manifold of motor car engine generally all is mounted between closure and the engine cylinder cover, main effect is the independent air inlet of satisfying each cylinder, intake manifold generally comprises collection chamber and intake manifold, collection chamber is communicated with closure, and intake manifold is connected to by flange that engine cylinder covers and is communicated with the inlet end of cylinder.Because the power of motor is relevant with the MAF that sucks motor, MAF is relevant with air density, after so engine displacement and rotating speed are determined, by can significantly improve the power of motor to the air precompression that enters cylinder, yet the intake manifold of at present general motor car engine is difficult to feed precompressed air when cylinder is ventilated, make that the intake efficiency of motor is low, power character and the Economy of motor are relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of intake manifold of motor, can obviously improve the intake efficiency that starts into, improves power character and the Economy of motor.
For achieving the above object, the utility model has adopted following technological scheme: a kind of intake manifold of motor, comprise collection chamber and intake manifold, it is characterized in that: be provided with resonance pressure charging mechanism between collection chamber and the intake manifold, described resonance pressure charging mechanism is made of the resonant cavity that is interconnected and resonant intake tube, resonant cavity is communicated with intake manifold, and resonant intake tube is communicated with collection chamber.
The beneficial effects of the utility model are: after adopting said structure, under certain engine speed, because the motion of piston cycle causes the gas resonance in the intake manifold, thereby form the resonator of last of the twelve Earthly Branches Mu Huoerzi, make gas that an additional pressurized effect be arranged, significantly improve the intake efficiency of motor, improved power character and the Economy of motor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of intake manifold of motor, as shown in Figure 1, comprise collection chamber 30 and intake manifold 20, be provided with resonance pressure charging mechanism 10 between collection chamber 30 and the intake manifold 20, described resonance pressure charging mechanism 10 is made of the resonant cavity 12 that is interconnected and resonant intake tube 11, resonant cavity 12 is communicated with intake manifold 20, and resonant intake tube 11 is communicated with collection chamber 30.Specifically, intake manifold 20 usefulness flanges are connected with cylinder 40, collection chamber 30 also is to be connected with intake manifold 50 with flange, under certain engine speed, when air passes through intake manifold 50 from the external world, after closure 60 enters collection chamber 30, pass through the resonant intake tube 11 of resonance pressure charging mechanism 10 again, resonant cavity 12 enters intake manifold 20, because the motion of piston cycle can cause the gas resonance in the intake manifold, thereby form the resonator of last of the twelve Earthly Branches Mu Huoerzi, like this through after the simple resonance pressure charging effect, significantly improve intake efficiency and the pressure of cylinder, thereby improved power character and the Economy of motor.
Further, in order to strengthen the gas resonance effect in the intake manifold, described resonance pressure charging mechanism 10 is some groups, and the resonant cavity 12 of every group of resonance pressure charging mechanism 10 is connected with even spaced apart intake manifold 20, the corresponding connection with cylinder block of described intake manifold 20.
Further, air inlet in order to ensure each cylinder is even, reduce simultaneously vibration and noise as much as possible, described resonant intake tube 11 is obliquely installed between resonant cavity 12 and collection chamber 30, resonant cavity 12 is consistent with the length direction of the cavity of collection chamber 30, and the angle β between resonant intake tube 11 and the resonant cavity 12 is 35 °～45 °.
