Abstract
The utility model discloses an engine gas inlet manifold, including the air intake manifold body, this internal intake duct, cooling chamber and gas off -take of being equipped with of air intake manifold, the gas off -take is a plurality of and equal by freezing chamber communicates with each other with the intake duct, be equipped with the guide plate that is used for air directed forced oil cooling intracavity in the intake duct, the utility model discloses an engine gas inlet manifold is equipped with the guide plate that carries out the water conservancy diversion to the air in the intake duct, make each cylinder body of each gas off -take and engine admit air evenly, improves the effective output power and the moment of torsion of engine, avoids causing that engine work is rough, noise at work big, each problem that jar work is inhomogeneous, engine life shortens.
Description
Technical field
The utility model relates to a kind of engine intake manifold.
Background technique
Along with the development of China's automobile industry, its Abgasgesetz, fuel economy and travelling comfort more and more come into one's own, the application of the technology such as supercharging, in-cylinder direct injection on petrol engine is more and more extensive for this reason, wherein, rationalization's engine charge, raising motor each cylinder intake uniformity just seem particularly important, and each cylinder air inlet uniformity of motor is the important prerequisite realizing engine stabilizer work.Intake manifold is as the air inlet system of motor, the cylinder body of the corresponding motor of air outlet channel arranges multiple, and mostly be linear array, in order to conserve space, the intake duct trend of usual intake manifold is parallel with the orientation of air outlet channel, therefore air is entered the transformation that there is the flow direction in the process of air outlet channel by intake duct, affect the intake uniformity of each air outlet channel, affect effective output and the moment of torsion of motor greatly, also cause the problems such as engine operation is rough, operating noise is large, each cylinder working is uneven, engine life shortening.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of engine intake manifold, make each cylinder body air inlet uniformity of each air outlet channel and motor, improve effective output and the moment of torsion of motor, avoid causing the problem that engine operation is rough, operating noise is large, each cylinder working is uneven, engine life shortens.
Engine intake manifold of the present utility model, comprises intake manifold body; Intake duct, cooling chamber and air outlet channel is provided with in described intake manifold body; Described air outlet channel is multiple and is all communicated with intake duct by cooling chamber; Be provided with for by the guide plate in air Directed cooling chamber in described intake duct.
Further, described cooling chamber is rectangular cavity; Described intake duct and air outlet channel are respectively in the wide to both sides of cooling chamber.
Further, described guide plate is the arc plate of the curving to cooling chamber place.
Further, described guide plate is two, and two guide plates are along cooling chamber length to arrangement.
Further, described guide plate and this body by integral forming of intake manifold.
The beneficial effects of the utility model are: engine intake manifold of the present utility model, guide plate air being carried out to water conservancy diversion is provided with in intake duct, make each cylinder body air inlet uniformity of each air outlet channel and motor, improve effective output and the moment of torsion of motor, avoid causing the problem that engine operation is rough, operating noise is large, each cylinder working is uneven, engine life shortens.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure: the engine intake manifold of the present embodiment, comprises intake manifold body 1; Intake duct 2, cooling chamber 3 and air outlet channel 4 is provided with in described intake manifold body 1; Described air outlet channel 4 is multiple and is all communicated with intake duct 2 by cooling chamber 3; Be provided with for by the guide plate 5 in air Directed cooling chamber 3 in described intake duct 2; The air in intake duct 2 is made evenly to enter in cooling chamber 3 by guide plate 5, and each air outlet channel 4 and cooling chamber 3 are just to setting, therefore the effect of each cylinder body air inlet uniformity making each air outlet channel 4 and motor is reached, improve effective output and the moment of torsion of motor, avoid causing the problem that engine operation is rough, operating noise is large, each cylinder working is uneven, engine life shortens.
In the present embodiment, described cooling chamber 3 is rectangular cavity; Described intake duct 2 and air outlet channel 4 are respectively in the wide to both sides of cooling chamber 3, compact structure, and space availability ratio is high, are beneficial to reduction overall engine volume, economize on material, weight reduction.
In the present embodiment, described guide plate 5 is the arc plate of the curving to cooling chamber 3 place, guide plate 5 is arranged in intake duct 2 outlet port, cooling chamber 3 is provided with the uncovered of a rectangle, the plane orthogonal at guide plate 5 and the uncovered place of cooling chamber 3, the length of guide plate 5 is fixed on intake duct 2 inwall to two ends, the wide of guide plate 5 all leaves gap between both sides edge and intake duct 2 inwall, make partial air under the effect of guide plate 5 in Directed cooling chamber 3, and the wide partial air to both sides of corresponding guide plate 5 still flows along intake duct 2 inwall, with compared with whole for guide plate 5 structure being close to intake duct 2 inwall, little to the obstruction of air, intake uniformity is better, and reinforing function can be played to intake duct 2 structure, improve the structural strength of intake duct 2, reduce rate of fault, adopt arc plate structure, reduce further the obstruction to air, reasonably the radian of design guide plate 5 can improve the accuracy of air-flow guiding simultaneously, improves intake uniformity further.
In the present embodiment, described guide plate 5 is two, and two guide plates 5 are long to arrangement along cooling chamber 3, improve intake uniformity further.
In the present embodiment, described guide plate 5 is one-body molded with intake manifold body 1; Save assembly cost, structural strength is high, is convenient to shaping.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
