[0002] In the related art, the exhaust gas recirculation system of the engine assembly is longitudinally arranged at the rear side of the engine assembly, but such arrangement will cause some problems.

[0033] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0034] Reference below Figure 1-Figure 4 An engine assembly 1 according to an embodiment of the present invention is described.

[0035] like Figure 2 and Figure 3 As shown, the engine assembly 1 according to the embodiment of the utility model comprises: a suspension 10 and an exhaust gas recirculation system 20. The suspension 10 is a structural member used to reduce and control the transmission of vibration of the engine assembly 1 and to play a supporting role. The exhaust gas recirculation system 20 is mainly used to return part of the exhaust gas discharged from the engine assembly 1 to the intake manifold 40 and enter the cylinder again together with the fresh mixed gas.

[0036] like Figure 2 and Figure 3 As shown, the exhaust gas recirculation system 20 is arranged on the lower side of the suspension 10. That is to say, the exhaust gas recirculation system 20 is arranged on the side of the suspension 10 of the engine assembly 1, which is convenient for the exhaust gas recirculation system 20 to take air before catalysis. In addition, it will not affect the assembly of the air conditioning warm air inlet and return pipes, nor will it cause the risk of heat damage to the surrounding high-voltage wiring harness, warm air pipeline, etc. due to the high temperature of the air intake pipe 23 of the exhaust gas recirculation system 20, and it can avoid the small gap between the exhaust gas recirculation system cooler 21 and the exhaust gas, which affects the cooling capacity of the exhaust gas recirculation system cooler 21.

[0037] Furthermore, if Figure 2 and Figure 3 As shown, the exhaust gas recirculation system 20 is overall arranged horizontally, which can be equipped with the DM5.0 all-in-one power domain controller, and avoids affecting the arrangement of the electric drive hybrid system 60 and the engine assembly bolts. The arrangement platform of the electric drive hybrid system 60 assembly bolts is simplified, and a tightening shaft tool can be used.

[0038] In addition, if Figure 3 and Figure 4As shown, the engine assembly 1 also includes: a timing cover, and the exhaust gas recirculation system 20 includes: an exhaust gas recirculation system cooler 21, and mounting parts 22 are respectively provided on both sides of the exhaust gas recirculation system cooler 21, and the mounting parts 22 are installed on the right side of the timing cover, or the shell of the exhaust gas recirculation system cooler 21 is integrated on the shell of the timing cover. The timing cover is generally fixed on the side of the engine assembly 1, connected to the cylinder body, and used to protect the timing gear and chain. The exhaust gas recirculation system cooler 21 is mainly used to cool the exhaust gas recirculation system 20. The mounting parts 22 can be respectively provided on both sides of the exhaust gas recirculation system cooler 21, and then the mounting parts 22 are installed on the right side of the timing cover, which is convenient for the installation of the exhaust gas recirculation system cooler 21. Of course, the shell of the exhaust gas recirculation system cooler 21 can also be integrated on the shell of the timing cover, which can improve the integration of the engine assembly 1, and the layout will be more streamlined, making the engine assembly 1 more compact as a whole.

[0039] Of course, if Figure 1-Figure 4 As shown, the engine assembly 1 further includes: a three-way catalytic converter 30 and an intake manifold 40, and the exhaust gas recirculation system 20 further includes: an air intake pipe 23 and an air outlet pipe 24, the air intake pipe 23 and the air outlet pipe 24 are respectively connected to the exhaust gas recirculation system cooler 21, and the air intake pipe 23 is connected to the front end cone of the three-way catalytic converter 30, and the air outlet pipe 24 is connected to the intake manifold 40. The gas can enter the exhaust gas recirculation system 20 through the air intake pipe 23, and then be discharged through the air outlet pipe 24, the air intake pipe 23 and the air outlet pipe 24 are respectively connected to the exhaust gas recirculation system cooler 21, so that when the gas is in the exhaust gas recirculation system 20, the exhaust gas recirculation system cooler 21 can cool the high-temperature gas. The air intake pipe 23 is connected to the front end cone of the three-way catalytic converter 30, so that the engine assembly 1 can take in air before catalysis, thereby effectively utilizing the unburned fuel before catalysis. The air outlet pipe 24 is connected to the intake manifold 40, so that the gas can enter the cylinder again through the intake manifold 40.

[0040] Among them, Figure 2 As shown, in the up-down direction, the air intake pipe 23 is higher than the front end cone of the three-way catalytic converter 30, and the air outlet pipe 24 is lower than the intake manifold 40. That is to say, the air intake pipe 23 is connected to the upper part of the front end cone of the three-way catalytic converter 30, and the air outlet pipe 24 is connected to the lower part of the intake manifold 40, so that the air intake system path of the exhaust gas recirculation system 20 will be in an upward extension state, thereby solving the problem of condensed water reflux and freezing, and avoiding affecting the operation of the engine assembly 1.

[0041] In addition, if Figure 2-Figure 4As shown, the exhaust gas recirculation system cooler 21 is tilted upward from the air intake pipe 23 to the air outlet pipe 24. The exhaust gas recirculation system cooler 21 is tilted upward, so that the air intake system path of the exhaust gas recirculation system 20 can be further extended upward, solving the problem of condensed water reflux and freezing, and avoiding affecting the operation of the engine assembly 1.

[0042] Furthermore, the exhaust gas recirculation system cooler 21 forms an angle α with the horizontal direction, and the value range of α is: 5°≤α≤10°. When the exhaust gas recirculation system cooler 21 is tilted upward, the exhaust gas recirculation system cooler 21 will form an angle with the horizontal direction. The angle α cannot be too small, that is, less than 5°, so that the exhaust gas recirculation system cooler 21 is not obviously tilted upward, and the problem of condensed water reflux and freezing cannot be better solved. Of course, the angle α cannot be too large, that is, greater than 10°, so that the exhaust gas recirculation system cooler 21 occupies too much space in the up and down directions, which is not conducive to the installation and arrangement of the exhaust gas recirculation system cooler 21.

[0043] Of course, if Figure 3 and Figure 4 As shown, the exhaust gas recirculation system 20 further includes: a control valve 25, which is connected between the exhaust gas recirculation system cooler 21 and the outlet pipe 24. The control valve 25 can control the communication. The control valve 25 is connected between the exhaust gas recirculation system cooler 21 and the outlet pipe 24, so that the control valve 25 can control the communication between the exhaust gas recirculation system cooler 21 and the outlet pipe 24. When part of the exhaust gas discharged from the engine assembly 1 needs to be returned to the intake manifold 40, the exhaust gas recirculation system cooler 21 and the outlet pipe 24 are connected, and when part of the exhaust gas discharged from the engine assembly 1 does not need to be returned to the intake manifold 40, the exhaust gas recirculation system cooler 21 and the outlet pipe 24 are disconnected.

[0044] The control valve 25 forms an angle β with the horizontal direction, and the value range of β is: 0<β<90°. Since the outlet pipe 24 is connected to the intake manifold 40, when the control valve 25 forms an angle β with the horizontal direction, the angle β is an acute angle, that is, the control valve 25 is tilted upward, and the space below the intake manifold 40 can be increased, so that the space below the intake manifold 40 can be fully utilized, and the convenience of assembly and maintenance of the water pump 90 can be improved.

[0045] According to an optional embodiment of the utility model, the connection end of the air intake pipe 23 and the exhaust gas recirculation system cooler 21, the connection end of the air outlet pipe 24 and the control valve 25, and the control valve 25 are located on the same straight line. In other words, the connection end of the air intake pipe 23 and the exhaust gas recirculation system cooler 21, the connection end of the air outlet pipe 24 and the control valve 25, and the control valve 25 are connected at 180 degrees, so that the connection end of the air intake pipe 23 and the exhaust gas recirculation system cooler 21 and the connection end of the air outlet pipe 24 and the control valve 25 can be directly connected, thereby improving the air intake and exhaust efficiency of the engine assembly 1.

[0046] It should be noted that the intake manifold 40 is tilted upward. The intake manifold 40 is tilted upward, that is, the intake manifold 40 is turned up, which can avoid the risk of mixed gas freezing in the intake manifold 40 when it is cold. Of course, the intake manifold 40 can also be turned down, which can make the size space of the engine assembly 1 in the vertical direction lower, which is conducive to improving collision performance such as pedestrian protection.

[0047] Of course, if Figure 1-Figure 3 As shown, the engine assembly 1 further includes: a throttle valve 50, which is arranged adjacent to the outlet pipe 24. The throttle valve 50 is a controllable valve for controlling the air entering the engine. After the gas enters the intake pipe, it will mix with gasoline to become a combustible mixture, thereby burning to form work. The throttle valve 50 is connected to the air filter box 70 at the top and the engine cylinder block at the bottom. Specifically, the throttle valve 50 is arranged on the right front side of the engine cylinder head, and is arranged on the timing cover side of the exhaust gas recirculation system 20, so that the throttle valve 50 is closer to the outlet pipe 24, so that the outlet pipe 24 can be more conveniently connected to the throttle valve 50 after being connected to the intake manifold 40.

[0048] Secondly, the throttle valve 50 is constructed as a four-point flange structure. It should be noted that when the intake manifold 40 is turned up, the height of the engine assembly 1 will increase, and the overall height will increase. The throttle valve 50 is constructed as a four-point flange structure. After the throttle valve 50 is installed, the height of the engine assembly 1 can be reduced to a certain extent, effectively solving the pedestrian protection problem.

[0049] In addition, if Figure 1 and Figure 2 As shown, the engine assembly 1 further includes: an electric drive hybrid system 60 and an air filter box 70, and the air filter box 70 is arranged at the front side of the electric drive hybrid system 60. The air filter box 70 is a structural component for air purification. The air filter box 70 is arranged at the front side of the electric drive hybrid system 60 to realize a platform arrangement of the air filter box 70, and in this way, the air filter box 70 is closer to the throttle 50, thereby facilitating the communication between the throttle 50 and the air filter box 70.

[0050] Alternatively, if Figure 2As shown, the engine assembly 1 further includes: a transmission shaft 80, and the three-way catalytic converter 30 is tilted upward to avoid the transmission shaft 80. It should be noted that the transmission shaft 80 is located below the exhaust gas recirculation system 20, and the three-way catalytic converter 30 is tilted upward. On the one hand, it is convenient for the exhaust gas recirculation system 20 to take air before catalysis, and on the other hand, the three-way catalytic converter 30 can avoid the position of the transmission shaft 80, so that the platform arrangement of the three-stage and two-stage transmission shaft 80 can be realized at the same time.

[0051] In addition, Figure 1 and Figure 2 As shown, the engine assembly 1 further includes: a water pump 90 and a thermostat, and the exhaust gas recirculation system 20 further includes: an inlet pipe 26 and an outlet pipe 27, the inlet pipe 26 and the outlet pipe 27 are respectively connected to the exhaust gas recirculation system cooler 21, and the inlet pipe 26 is connected to the water outlet of the water pump 90, and the outlet pipe 27 is connected to the thermostat. The inlet pipe 26 can play a role of water inlet, and the outlet pipe 27 can play a role of water outlet. The inlet pipe 26 and the outlet pipe 27 are respectively connected to the exhaust gas recirculation system cooler 21, so that the coolant can enter the exhaust gas recirculation system cooler 21, thereby realizing the cooling effect of the exhaust gas recirculation system cooler 21. The liquid inlet pipe 26 is located at the water outlet of the water pump 90 and is connected to the water outlet of the water pump 90, thereby shortening the length of the liquid inlet pipe 26 and maximizing the thermal management capability of the engine assembly 1. The liquid outlet pipe 27 goes around the front side of the engine and is directly connected to the thermostat, and then directly connected to the high-temperature radiator. Similarly, this can effectively shorten the length of the liquid outlet pipe 27 and maximize the thermal management capability of the engine assembly 1.

[0052] It should be noted that if Figure 3 and Figure 4 As shown, the liquid inlet pipe 26 is gradually bent downward. In other words, the overall trend of the liquid inlet pipe 26 extends downward, thus avoiding the water channel of the exhaust gas recirculation system 20 from forming an inverted "U"-shaped structure, thereby preventing the risk of gas accumulation.
