Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

The following describes an air intake assembly 100 of an engine according to an embodiment of the present invention with reference to fig. 1 to 11, and the present invention also provides an engine having the air intake assembly 100 of the engine and a vehicle having the engine.

As shown in fig. 1 to 6, an intake assembly 100 of an engine includes: an intake manifold 10, an intercooler 20, and a first throttle 30.

The intercooler 20 has an air inlet 21 and an air outlet 22, and the air outlet 22 is communicated with the intake manifold 10. So set up, because the temperature of engine exhaust waste gas is very high, the temperature of admitting air can be increased through the pressure boost of booster, and the air density can rise at the in-process of compression, also lead to the exhaust air temperature of booster to rise simultaneously, rise along with atmospheric pressure, oxygen density reduces, influence the effective combustion efficiency of engine greatly, therefore, utilize intercooler 20 to cool off the high-temperature air that comes from the booster, and the air after the intercooler 20 cooling passes through intake manifold 10 and gets into in the engine cylinder body, release with fuel mixed combustion, the heat load of engine that can greatly reduced, improve the air input, and then improve the effective efficiency of burning of engine, thereby promote the dynamic behavior of vehicle. Moreover, the air outlet 22 of the intercooler 20 is directly communicated with the intake manifold 10, so that the structural integration degree formed by the intercooler 20 and the intake manifold 10 is higher, and the intercooler 20 can be more favorably arranged in an engine room with limited space.

And, a first throttle valve 30 is provided on the intake port 21 to control the amount of intake air. With the arrangement, the amount of gas entering the intercooler 20 can be accurately controlled, so that the air inflow of the intercooler 20 is almost the required amount of the engine, the air entering the intake manifold 10 can be fully combusted, the effective combustion efficiency of the engine is effectively improved, and the oil consumption is greatly reduced. Compared with the existing engine, the engine can control the air inflow of the intercooler 20 through the first throttle valve 30 according to different working conditions and different air inflow requirements, and different requirements are met. Moreover, the amount of gas to be cooled by the intercooler 20 is reduced, and the volume of the intercooler 20 can be effectively reduced, so that the whole engine compartment is compactly arranged, the small compartment space arrangement requirement can be met, and the design freedom of the whole vehicle is greatly improved.

If the first throttle valve 30 is provided on the air outlet 22, i.e., the first throttle valve 30 is provided between the intercooler 20 and the intake manifold 10, the overall height position is increased, which is disadvantageous in terms of spatial arrangement; moreover, when the intake air amount required by the engine is large, the whole amount of the gas in the intercooler 20 can be sent to the engine block, and the gas can be continuously sent to the engine block after entering the intercooler 20 for cooling, but when the intake air amount required by the engine is small, the first throttle 30 needs to be adjusted to send part of the gas amount in the intercooler 20 to the engine block through the intake manifold 10, so that the whole amount of the gas in the intercooler 20 is not fully utilized, and part of the gas amount remains in the intercooler 20, which results in a large-volume structure for the intercooler 20, so as to accommodate the remained gas amount, and thus, the use of the internal space of the intercooler 20 is wasted. Therefore, by providing the first throttle valve 30 on the air intake 21, on the one hand, the first throttle valve 20 can be installed between the intake line and the intercooler 20, making the most of the arrangement space between the intake line and the intercooler 20, without increasing the overall height; on the other hand, by adjusting the opening degree of the first throttle valve 20, the amount of intake air entering the intercooler 20 can be adjusted to just meet the amount of intake air required by the engine, so that there is no problem of waste of the internal space of the intercooler 20, and the volume of the intercooler 20 is relatively small, so as to better match the arrangement in the engine compartment. In addition, the edge of the air inlet 21 of the intercooler 20 forms a flange structure, the flange structure matched with the edge of the air inlet 21 is formed at one end of the air inlet 21 of the intercooler 20 and one end of the first throttle valve 30, so that the edge of one end of the first throttle valve 30 and the edge of the air inlet 21 is fixedly connected through a flange, the other end of the first throttle valve 30 is fixedly connected with the air inlet pipe 70, the intercooler 20 is directly connected with the first throttle valve 30, the whole air inlet pipe 70 is shortened, the pressure loss of air flowing in the air inlet pipe 70 is reduced, the power delay of an engine can be reduced, and the transient response of the engine is improved. The air inlet pipe 70 can be a hose, so that air inlet noise can be effectively absorbed and reduced, a certain damping effect is achieved, and the NVH performance of the engine is improved; wherein the intake duct 70 may be fixedly connected to the other end of the first throttle valve 30 by means of a clamp.

Therefore, the first throttle valve 30 is arranged at the air inlet 21 of the intercooler 20, so that the amount of air entering the intercooler 20 can be accurately controlled, the air entering the air inlet manifold 10 can be sufficiently combusted, the combustion efficiency of the engine is effectively improved, the size of the intercooler 20 is effectively reduced, and arrangement in an engine compartment is facilitated.

Moreover, the air inflow required to be cooled by the intercooler 20 is small, the size of a product is feasible to be reduced, the size of the intercooler 20 can be reduced by 1/3-1/4 compared with the size parameter of the conventional intercooler 20, the whole size of a power system can be effectively reduced while the demand of an engine is met, the product cost is saved, sufficient arrangement space can be provided for an engine compartment, and the intercooler 20 is particularly suitable for the intercooler 20 with a small size under the condition that the arrangement space of a hybrid vehicle is compact. Of course, the volume parameter of the intercooler 20 is not limited to the above value, and may be arranged according to the designed intake air demand.

As shown in fig. 6 to 8, a first air inlet section 241, a second air inlet section 242 and a third air inlet section 243 are sequentially arranged in the air inlet chamber 24, the first air inlet section 241 is communicated with the air inlet 21, and the third air inlet section 243 is communicated with the intercooler body 23, so that the air can be uniformly guided into the intercooler body 23. So configured, the gas may uniformly enter the intercooler body 23 through the first air inlet section 241, the second air inlet section 242, and the third air inlet section 243 in sequence.

The cross-sectional area of the third air intake section 243 is larger than that of the first air intake section 241, and the second air intake section 242 is divergent. With such an arrangement, the sectional area of the first air intake section 241 is smaller, and the sectional area of the second air intake section 242 gradually expands, so that the sectional area of the first air intake section 241 can be gradually expanded to be the same as that of the third air intake section 243, and the shape of the air intake chamber 24 is in a gradually expanding structure in the air intake direction, so that the air slowly enters from the first air intake section 241, and gradually expands to the third air intake section 242 through the second air intake section 242, so that the air can more uniformly enter the intercooler body 23.

In the vertical cross section, the divergent angle of the second air intake section 242 is α, and α satisfies the relationship: alpha is more than or equal to 50 degrees and less than or equal to 70 degrees. So configured, the cross-section in the up-down direction may be understood as creating a cross-sectional configuration of the intake chamber 24 in the up-down direction that is cut away from the intake chamber 24 in the X-Y plane. In the air intake direction, the air intake chamber 24 is not a conventional boss structure, but is composed of a first air intake section 241, a second air intake section 242, and a third air intake section 243 that are communicated in this order.

With such an arrangement, the gas cooled in the intercooler body 23 can uniformly enter the intake manifold 10 through the first gas outlet section 251, the second gas outlet section 252 and the third gas outlet section 253 in sequence, so that the gas uniformly enters the engine cylinder to be sufficiently combusted.

The cross-sectional area of the third outlet segment 253 is larger than that of the first outlet segment 251, and the second outlet segment 252 is tapered. With such an arrangement, in the gas outlet direction, the sectional area of the first gas outlet section 251 is larger, and gradually decreases along with the sectional area of the second gas outlet section 252, and decreases to be the same as the sectional area of the third gas outlet section 251, so that the outer shape of the gas outlet chamber 25 is in a tapered structure in the gas outlet direction, and thus, after a large amount of gas enters the first gas outlet section 251, the gas gradually decreases to the third gas outlet section 251 through the second gas outlet section 252, so that the gas can more uniformly enter the gas inlet manifold 10.

In the cross section in the vertical direction, the taper angle of the second gas outlet section 252 is β, and β satisfies the relation: beta is more than or equal to 20 degrees and less than or equal to 40 degrees. So configured, the cross-section in the up-down direction can be understood as creating a cross-sectional structure in which the X-Y plane cuts through the outlet chamber 25 to form the outlet chamber 25 in the up-down direction. In the air outlet direction, the sectional area of the first air outlet section 251 is larger, the sectional area of the first air outlet section 251 is gradually reduced along with the sectional area of the second air outlet section 252, and is reduced to be the same as the sectional area of the third air outlet section 251, and the air inlet direction of the first air outlet section 251 is perpendicular to the air inlet direction of the third air outlet section 253, and by setting the taper angle β of the second air outlet section 252 between 20 ° and 40 °, the air can slowly and uniformly flow into the air inlet manifold 10 through the first air outlet section 251, the second air outlet section 252 and the third air outlet section 253 in sequence, so that the air can slowly flow into the air inlet manifold 10, the cooling efficiency of the intercooler 20 is improved, and the cooling performance can be improved by 2% to 3% or even more.

So configured, the cross-section in the front-rear direction can be understood as creating a Y-Z plane cutting the outlet chamber 25 to form a cross-sectional structure of the outlet chamber 25 in the front-rear direction. The second air outlet section 252 is arranged at the taper angle gamma of 25-35 degrees on the cross section in the front-back direction, so that uniform flow of air is facilitated, the loss of air flow is reduced, and the pressure loss of the intercooler 20 is effectively reduced, so that the air inflow entering the air inlet manifold 10 is almost the demand of the engine, and meanwhile, the air can slowly and uniformly flow better by combining the taper angle arrangement of the second air outlet section 252 on the cross section in the up-down direction, so that the cooling efficiency of the intercooler 20 is further improved.

Moreover, the upper portion and the lower portion of the back of the air inlet chamber 24 are respectively provided with a left support, and the upper portion and the lower portion of the back of the air outlet chamber 25 are respectively provided with a right support.

Further, the intake assembly 100 of the engine further includes: a second throttle valve provided between intercooler 20 and intake manifold 10 for adjusting the amount of exhaust gas. So set up, set up the second throttle between intercooler 20 and intake manifold 10, can accurate regulation get into intake manifold 10's gas quantity for the air input matches with the demand of engine, makes gas and fuel in the engine cylinder body can fully burn, has improved the burning high efficiency of engine. In conjunction with the setting of the first throttle valve 20, the amount of gas taken into the intake manifold 10 can be controlled more accurately, so that the intake air amount more closely matches the required amount of the engine. When the engine is normally operated, the opening degree of the first throttle valve 20 may be smaller than that of the second throttle valve, and although there may be a problem that a part of the gas quantity remains in the intercooler 20, the first throttle valve 20 may be adjusted in time to slow down the accumulation speed of the gas quantity in the intercooler 20, so that the volume of the intercooler 20 may still be set smaller than that in the prior art, so as to be suitable for being arranged in an engine room with a smaller space.

Moreover, the intercooler 20 having a small volume is disposed above the intake manifold 10, so that the entire installation structure is compact, which is advantageous for the freedom of design of the engine compartment and cost saving. Meanwhile, in order to reduce the vibration of the intercooler 20, the cylinder head 40 is provided with the mounting bracket 50 for fixedly connecting the intercooler 20 and/or the first intake valve 30, so that the mounting mode of the whole intercooler 20 can be effectively improved, and the NVH performance can be improved.
