Torque, avoids the problem that causing that engine rough running, operating noise are big, each cylinder working is uneven, engine life shortens.
The integrated form inlet manifold of the present invention, including inlet manifold ontology and charge air cooler；It is set in the inlet manifold ontology
There are air intake duct, cooling chamber and gas off-take；The gas off-take is multiple and is communicated with air intake duct by cooling chamber；It is cold in described
Device is fixedly installed in cooling chamber；It is equipped in the air intake duct for by the deflector of air-flow Directed cooling intracavitary.
Further, the cooling chamber is rectangle cavity；The air intake duct and gas off-take are respectively in the wide to two of cooling chamber
Side.
Further, the deflector is the arc panel to the curving where cooling chamber.
Further, the deflector is two, and two deflectors are grown along cooling chamber to arrangement.
Further, the deflector and this body by integral forming of inlet manifold.
Further, the charge air cooler includes cover board and core；The cover board is fixed on the opening of cooling chamber by fastener
Place；The core is fixed on the inside of cover board.
Further, the charge air cooler further includes two cooling pipe fittings for being fixed on cover board；It is equipped with and is used in the core
For the coolant flow channel for cooling down media flow and being communicated with two cooling pipe fittings.
Further, the gap that coolant flow channel is corresponded in the core is equipped with the gas channel communicated with cooling chamber.
The beneficial effects of the invention are as follows：The integrated form inlet manifold of the present invention, makes each cylinder of each gas off-take and engine
Body air inlet uniformity is conducive to increase atmospheric density, improves effective output and the torsion of engine to the good cooling results of air
Square, avoids the problem that causing that engine rough running, operating noise are big, each cylinder working is uneven, engine life shortens.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is inlet manifold body construction schematic diagram.
Specific implementation mode
Fig. 1 is the structural diagram of the present invention, and Fig. 2 is inlet manifold body construction schematic diagram, as shown in the figure：The present embodiment

But chamber 3 and gas off-take 4；The gas off-take 4 is multiple and is communicated with air intake duct 2 by cooling chamber 3；The charge air cooler 6 is solid
Dingan County is loaded in cooling chamber 3；It is equipped in the air intake duct 2 for by the deflector 5 in air-flow Directed cooling chamber 3；Pass through water conservancy diversion
Plate 5 makes the air in air intake duct 2 even into cooling chamber 3, and charge air cooler 6 is set in cooling chamber 3 and is allowed to and inlet manifold ontology 1
Become one, thus air be fully cooled by charge air cooler 6 in the cooling chamber 3 after enter each gas off-take 4, cooling effect
Fruit is good, and atmospheric density is big, and each gas off-take 4 and 3 face of cooling chamber are arranged, therefore reaches and make each of each gas off-take 4 and engine
The effect of a cylinder body air inlet uniformity improves the effective output and torque of engine, avoids causing engine rough running, work
Make the problem of noise is big, each cylinder working is uneven, engine life shortens.
In the present embodiment, the cooling chamber 3 is rectangle cavity；The air intake duct 2 and gas off-take 4 are respectively in cooling chamber 3
It is wide to both sides；Compact-sized, space availability ratio is high, is conducive to reduction engine overall volume, economizes on material, mitigates weight.
In the present embodiment, the deflector 5 is the arc panel to the curving where cooling chamber 3；Deflector 5 is arranged in
