Pipe 16, the second air inlet pipe 6;Wherein, inlet manifold 1 is used for the air inlet by air, natural gas mixture distribution into each cylinder air intake duct
Bend pipe 2 is connect with inlet manifold 1, and exhaust gas recirculatioon module 3 is connect with intake elbow 2;Further, exhaust gas recirculatioon module 3
It being connect with the first control valve 5, the first control valve 5 is connect with the first air inlet pipe 16, and the first air inlet pipe 16 is used to introduce fresh air,
Meanwhile exhaust gas recirculatioon module 3 and the second air inlet pipe 6 connect, the second air inlet pipe 6 is for introducing exhaust gas, and the second control valve 4 is solid
Surely it is connected in exhaust gas recirculatioon module 3.
In the utility model embodiment, admission line is additionally provided with the gas inlet pipe 18 to introduce natural gas and sets
In the combustion gas diffusion hole 20 of gas inlet pipe 18, the combustion gas diffusion hole 20 can by inside Gas diffusion to admission line, into
And it can be realized being sufficiently mixed for natural gas and air.
In addition, admission line is also in order to which the mass flow that precise measurement natural gas mixes with air rear gas may be implemented
Equipped with testing tube, which connect with feedback section 26, and certainly, according to actual needs, which specifically can be set to text
Venturi, that is to say, that can use the flow of structural principle measurement both air and the natural gas gaseous mixture of Venturi tube.
More particularly, the inside of Venturi tube is equipped with combustion gas closing in channel 21, both air and natural gas gaseous mixture
When by combustion gas closing in channel 21, since section reduces, gas accelerates in channel, and the characteristic of Venturi tube is utilized;Accordingly
, the flowmeter in Venturi tube can be with the mass flow of the mixed gas of precise measurement, finally, both air and natural gas
Gaseous mixture and exhaust gas meet mixing in admission line, and air, natural gas and the mixed gas of exhaust gas are spread by gaseous mixture
When channel 24, section increases, and gas flow rate reduces, and eventually enters into inlet manifold 1.
In addition, entering waste gas and recycles control channel 25 by the exhaust gas of the second control valve 4, then entered by inner passage
Exhaust gas circulation passage 23, exhaust gas by exhaust gas recycling closing in channel 22 when, section reduce, gas flow rate increase, finally into
Enter admission line.
In order to optimize above-described embodiment, rhone 19 is additionally provided in admission line, which should be set to air inlet
The bottom of the inner sidewall of pipeline, for example, according to the specific structure of admission line, it can be in intake elbow 2 and exhaust gas recirculatioon
Rhone 19 is arranged in the bottom of the inner sidewall of module 3, a large amount of due to containing in the gaseous mixture of air, natural gas and exhaust gas
Steam, when gas flow rate is slack-off, steam can condense into water droplet, and water droplet can be introduced to inlet manifold by above-mentioned set-up mode
In 1, the evaporation of water droplet may finally be realized, to guarantee the stability and peace of exhaust gas recirculatioon module 3 and all parts work
Quan Xing.
On the basis of the above, inlet duct further includes anti-surge valve 14 and anti-surge valve adapter tube welding assembly 12, wherein anti-
One end of surge valve adapter tube welding assembly 12 is fixed on engine right side ontology by anti-surge valve adapter tube welding assembly bracket 11,
The other end is fixed on by the second support 9 of the second air inlet pipe 6 on the left of engine on ontology, so as to realize that anti-surge valve connects
Pipe welding assembly 12 connect reliability, with prevent it is vibrated greatly cause anti-surge valve adapter tube welding assembly 12 cracking;Anti-surge
Valve adapter tube welding assembly 12 is connected by rubber tube 13 and anti-surge valve 14, and one end of anti-surge valve 14 can also pass through rubber tube
13 and first air inlet pipe 16 connect, the other end also by rubber tube 13 and be pressurized before piping connection;Signal on anti-surge valve 14
Mouth is connected by anti-surge valve connecting tube 15 and intake elbow 2.
So, it may be implemented when engine slows down suddenly, the first control valve 5 is closed, and pressurized gas is caused
It cannot be introduced into cylinder, to make the gas pressure of 2 the inside of gas pressure raising and intake elbow of 16 the inside of the first air inlet pipe
It reduces, at this point, the gas pressure that anti-surge valve 14 can perceive in intake elbow 2 declines suddenly, leads to inside anti-surge valve 14
Road is opened, and then the high pressure gas in the first air inlet pipe 16 is introduced pressurization front tube by anti-surge valve adapter tube welding assembly 12
Road, so as to release stress, to reduce the risk of engine surge.
In order to guarantee the fixing of the second air inlet pipe 6 connection, several brackets and pipe clamp can also be set, wherein branch
Frame is used to the second air inlet pipe 6 being fixedly installed in engine cylinder body, and pipe clamp is sheathed on the lateral wall of the second air inlet pipe 6, pipe clamp
Second air inlet pipe 6 can be fixed on bracket, can prevent from vibrating excessive and the second air inlet pipe 6 being caused to crack in this way;For example, can
First support 7, the first pipe clamp 8 and second support 9, the second pipe clamp 10 is arranged, first support 7 and the first pipe clamp 8 are cooperatively connected,
Second support 9 and the second pipe clamp 10 are cooperatively connected.
In addition, the second air inlet pipe 6 is additionally provided with the first bellows and the second bellows, to make up the foozle of pipe fitting and
The installation of part is not influenced;One end of second air inlet pipe 6 connects exhaust manifold, and the other end connects exhaust gas recirculatioon module 3, thus
Realization introduces exhaust gas into exhaust gas recirculatioon module 3;Exhaust gas recirculatioon module 3 is further fixed on air inlet by module carrier 17
On manifold 1, since exhaust gas recirculatioon module 3 is longer, so that forming longer cantilever design, module carrier 17 can effectively drop
The vibration of low exhaust gas recirculatioon module 3.
