Description

The present disclosure relates to vehicles.

Conventionally, various proposals have been made for vehicles having a supercharger and an internal combustion engine (Japanese Patent Application Laid-Open No. 2019-065795).

JP 2019-065795 A

A hybrid vehicle includes an internal combustion engine, a rotating electrical machine, and an electronic device such as a PCU (power control unit). The rotating electrical machine functions as a motor that drives the drive wheels, or as a generator.

The PCU includes a boost converter and an inverter. The PCU is electrically connected to the rotating electrical machine, and supplies AC power to the rotating electrical machine, converts the AC power supplied from the rotating electrical machine into DC power, and supplies the DC power to the battery.

Since the PCU is equipped with a plurality of elements such as IGBTs (Insulated Gate Bipolar Transistors) and diodes, the electronic equipment such as the PCU is easily affected by heat. It is conceivable to mount a supercharger on the hybrid vehicle as described above. On the other hand, superchargers generally tend to reach high temperatures.

Therefore, if a hybrid vehicle is simply equipped with a supercharger, heat from the supercharger may thermally affect electronic devices.

The present disclosure has been made in view of the problems as described above, and an object thereof is to provide a vehicle including an internal combustion engine, a rotating electric machine, and an electronic device that controls driving of the rotating electric machine. To provide a vehicle in which an electronic device is restrained from being thermally affected by heat from a supercharger.

A vehicle according to the present disclosure includes an internal combustion engine, a rotating electrical machine, an electronic device that controls driving of the rotating electrical machine and is provided adjacent to the internal combustion engine in a first direction, and an electronic device provided at a position adjacent to the internal combustion engine in a first direction; and a supercharger provided at a position adjacent to the internal combustion engine in a second direction intersecting the first direction and connected to the internal combustion engine. Prepare. The supercharger includes a turbine and a compressor driven by exhaust gas supplied from the internal combustion engine. In the first direction, the turbine was positioned farther from the electronics than the compressor.

In the vehicle described above, when the supercharger is driven, the temperature of the turbine tends to become higher than the temperature of the compressor. On the other hand, the turbine is located farther from the electronics than the compressor. Therefore, the heat from the turbine is suppressed from reaching the electronic equipment.

The vehicle further comprises an intake pipe connected to the compressor and supplying outside air to the compressor. The intake pipe is arranged so as to pass between the internal combustion engine and the electronic equipment.

In the vehicle described above, the intake pipe is arranged between the internal combustion engine and the electronic equipment, so that a part of the surface of the electronic equipment is covered with the intake pipe when viewed from the supercharger. As a result, part of the radiant heat radiated from the turbine toward the electronic device enters the intake pipe, and it is possible to suppress an increase in the temperature of the electronic device. In addition, since outside air supplied to the compressor flows through the intake pipe, the temperature of the intake pipe is unlikely to rise. Therefore, even if the intake pipe is arranged between the electronic equipment and the internal combustion engine, the thermal influence of the intake pipe on the electronic equipment is small.

The vehicle further comprises an exhaust pipe connected to the turbine and a catalyst unit connected to the exhaust pipe. The catalyst unit is located farther from the electronics than the compressor.

According to the above vehicle, the exhaust gas also flows through the catalyst unit, and the temperature of the catalyst unit also rises. On the other hand, since the catalyst unit is farther from the electronic equipment than the compressor, heat from the catalyst unit can be suppressed from reaching the electronic equipment.

The catalyst unit includes a first catalyst member and a second catalyst member, the first catalyst member being provided upstream of the exhaust pipe relative to the second catalyst member, and in the first direction, The first catalyst member is positioned adjacent to the compressor.

In the above vehicle, the temperature of the first catalyst member is higher than that of the second catalyst member. On the other hand, the radiant heat radiated from the first catalyst member is likely to be blocked by the compressor, and it is possible to suppress the radiant heat from the first catalyst member from reaching the electronic device.

The first direction is the vehicle width direction, and the second direction is the vehicle front-rear direction. and adjacent to the internal combustion engine in the vehicle width direction.

According to the vehicle according to the present disclosure, it is possible to suppress the electronic device from being thermally affected by the heat from the supercharger.

Exhaust valves 46, intake valves 47, and spark plugs 48 are arranged in the cylinder head 34 at positions corresponding to the cylinders 45a, 45b, 45c, and 45d. For example, the cylinder 45 a is provided with two exhaust valves 46 , two intake valves 47 and spark plugs 48 . The other cylinders 45b, 45c, and 45d are also provided with exhaust valves and the like like the cylinder 45a.

An intake manifold 50 is connected to the intake port of each cylinder 45a, 45b, 45c, 45d.

The ECU 8 is provided at a position adjacent to the PCU 6 in the width direction (first direction) W, and the ECU 8 is arranged on the side opposite to the internal combustion engine 2 with respect to the PCU 6 . The ECU 8 includes a memory, a CPU (Central Processing Unit), and the like, and includes a board on which a plurality of electronic elements are mounted. Therefore, the ECU 8 is also a device that is easily affected by heat.

The vehicle front-rear direction D is a direction orthogonal to the vehicle width direction W. As shown in FIG. In the example shown in FIG. 2 , the supercharger 9 is arranged behind the cylinder head 34 .

The supercharger 9 includes a compressor 55 , a turbine 56 , a shaft 57 , a compressor housing 58 , a turbine housing 59 and a bearing housing 60 .

Compressor 55 is housed within compressor housing 58 and turbine 56 is housed within turbine housing 59 . A shaft 57 is provided to connect the compressor 55 and the turbine 56 and is housed within the bearing housing 60 . A plurality of bearings that rotatably support the shaft 57 are provided inside the bearing housing 60 .

An intake pipe 61 is connected to the compressor housing 58 , and an intake port 62 is formed in the intake pipe 61 . A filter 63 is provided in the intake pipe 61 . The filter 63 is arranged on the front side of the vehicle 1 with respect to the internal combustion engine 2 .

The intake pipe 61 is arranged to extend from the filter 63 toward the rear side of the vehicle 1 , pass between the housing case 37 of the PCU 6 and the internal combustion engine 2 , and then be connected to the compressor housing 58 . A supply pipe 64 is connected to the compressor housing 58 , and the supply pipe 64 is connected to an intercooler 65 . The intercooler 65 is arranged on the front side of the internal combustion engine 2 , and the supply pipe 64 is formed to extend forward of the vehicle 1 from the compressor housing 58 . Intercooler 65 is connected to intake manifold 50 .

A throttle valve 66 is provided at a connection portion between the intercooler 65 and the intake manifold 50 .

A turbine housing 59 is connected to the exhaust manifold 51 , and an exhaust pipe 68 is further connected to the turbine housing 59 .

A catalyst unit 70 is provided in the exhaust pipe 68 . Exhaust pipe 68 includes pipe 75 , pipe 76 and pipe 77 , and catalyst unit 70 includes catalyst member 71 and catalyst member 72 , as shown in FIG.

The catalyst member 71 is provided at a position adjacent to the turbine housing 59 in the vehicle width direction W, and the pipe 75 extends from the turbine housing 59 in the vehicle width direction W and is separated from the PCU 6 . A pipe 75 is connected to the catalyst member 71 .

The pipe 76 is connected to the catalyst member 71 . The pipe 76 extends downward from the catalyst member 71 and is formed to extend in the vehicle width direction W and to approach the PCU 6 .

The pipe 76 is connected to the catalyst member 72 , and the catalyst member 72 is connected to the pipe 77 . Piping 77 is formed to extend rearward of vehicle 1 from catalyst member 72 .

Catalyst member 71 and catalyst member 72 are both arranged at positions further from PCU 6 in vehicle width direction W than compressor 55 and compressor housing 58 .

In FIG. 2 , in the vehicle 1 configured as described above, when the internal combustion engine 2 is driven, exhaust gas flows into the turbine housing 59 through the exhaust manifold 51 . As the exhaust gas flows into the turbine housing 59, the turbine 56 rotates.

When the turbine 56 rotates, the shaft 57 rotates, and the compressor 55 connected to the shaft 57 also rotates.

As the compressor 55 rotates, air is drawn through the air intake 62 . Then, the air sucked from the intake port 62 passes through the filter 63 to remove foreign matter such as dust in the air.

The air from which foreign matter has been removed enters the compressor housing 58 and is compressed by the rotation of the compressor 55 . Air compressed within the compressor housing 58 passes through the supply pipe 64 and enters the intercooler 65 . The air supplied to the intercooler 65 is cooled within the intercooler 65 . The air cooled by the intercooler 65 passes through the intake manifold 50 and is supplied to the cylinders 45a, 45b, 45c and 45d.

Then, the fuel is burned together with the air supplied with the fuel in the cylinders 45 a , 45 b , 45 c , 45 d , and the high temperature exhaust gas is discharged from the exhaust manifold 51 . Exhaust gas then enters the turbine housing 59 .

Thus, the supercharger 9 uses the exhaust gas from the internal combustion engine 2 to supply the internal combustion engine 2 with compressed air.

Since the outer surface of the turbine 56 and the inner surface of the turbine housing 59 are exposed to hot exhaust gas from the internal combustion engine 2, the turbine 56 and the turbine housing 59 become hot. The high-temperature exhaust gas then sequentially passes through the catalyst member 71 and the catalyst member 72 .

The inner surface of the compressor housing 58 and the compressor 55 are exposed to air drawn in from the outside. Since the outside air temperature is lower than the exhaust gas temperature, the temperature of the turbine 56 and turbine housing 59 will be higher than the temperature of the compressor housing 58 and compressor 55 .

Here, the turbine 56 and the turbine housing 59 are located farther from the housing case 37 of the PCU 6 than the compressor 55 and the compressor housing 58 are. Therefore, heat from the turbine 56 and the turbine housing 59 is suppressed from reaching the housing case 37 of the PCU 6 .

Turbine 56 and turbine housing 59 are arranged on the opposite side of PCU 6 with respect to compressor 55 and compressor housing 58 . Therefore, the radiant heat radiated from the turbine 56 and the turbine housing 59 is easily blocked by the compressor housing 58 , and the radiant heat from the turbine 56 and the turbine housing 59 is suppressed from reaching the housing case 37 .

Since high-temperature exhaust gas also flows through the catalyst members 71 and 72, the catalyst members 71 and 72 also become hot. Here, catalyst members 71 and 72 are both arranged at positions farther from PCU 6 than compressor 55 and compressor housing 58 , so that the heat of catalyst members 71 and 72 is prevented from reaching PCU 6 . can.

Since the catalyst member 71 is arranged upstream of the catalyst member 72 in the flow direction of the exhaust gas, the temperature of the catalyst member 71 tends to be higher than that of the catalyst member 72 . On the other hand, the catalyst member 71 is provided at a position adjacent to the supercharger 9 in the vehicle width direction W, and the radiant heat from the catalyst member 71 is easily blocked by the supercharger 9 .

The intake pipe 61 is connected to the compressor housing 58 and is arranged so as to pass through a gap between the housing case 37 and the internal combustion engine 2 . Therefore, the intake pipe 61 partially covers the side surface of the housing case 37 , thereby suppressing the radiant heat from the turbine housing 59 from reaching the housing case 37 .

Since the intake pipe 61 partially covers the side surface of the housing case 37 , the heat from the internal combustion engine 2 is also suppressed from reaching the housing case 37 . Outside air having a relatively low temperature passes through the intake pipe 61 , and since the intake pipe 61 partially covers the side surface of the storage case 37 , there is almost no thermal effect on the storage case 37 .

FIG. 5 is a plan view schematically showing the inside of the storage case 37. As shown in FIG. The number of active elements such as IGBTs included in first inverter 40 and second inverter 41 is greater than that included in converter 42 . Furthermore, the number of diodes included in first inverter 40 and second inverter 41 is also greater than that in converter 42 . Therefore, first inverter 40 and second inverter 41 are more affected by heat than converter 42 .

A first inverter 40 , a second inverter 41 , and a converter 42 are accommodated in the accommodation case 37 . In the storage case 37 , the first inverter 40 and the second inverter 41 are provided at positions farther from the supercharger 9 than the converter 42 is.

Therefore, heat from the supercharger 9 can be suppressed from reaching the first inverter 40 and the second inverter 41 .

FIG. 6 is a side view schematically showing the internal combustion engine 2, PCU 6 and supercharger 9. As shown in FIG. As shown in FIG. 6, the PCU 6 is located below the supercharger 9 in the vertical direction. The air positioned around the supercharger 9 tends to move upward due to the heat of the supercharger 9 . On the other hand, since the PCU 6 is positioned below the supercharger 9 , the PCU 6 is prevented from being warmed by the air warmed by the heat of the supercharger 9 .

The ECU 8 shown in FIG. 2 and the like is provided on the side opposite to the internal combustion engine 2 with respect to the PCU 6 . Therefore, radiant heat from the supercharger 9 is easily blocked by the PCU 6 , and it is possible to suppress the radiant heat from the supercharger 9 from reaching the ECU 8 .

Also, the distance between the ECU 8 and the supercharger 9 is longer than the distance between the PCU 6 and the supercharger 9 . Therefore, radiant heat from the supercharger 9 and air warmed by the supercharger 9 are suppressed from reaching the ECU 8 .

FIG. 7 is a perspective view showing a supercharger 9A that is a modification of the supercharger 9. As shown in FIG. The turbine housing 59 of the supercharger 9A includes a peripheral surface 79 and end surfaces 78A, 78B. The end face 78A is connected to the bearing housing 60, and the end face 78B is an end face positioned opposite to the end face 78A.

The supercharger 9</b>A has a cover 80 that covers the turbine housing 59 . Cover 80 includes a top plate 81 , a rear plate 82 and side walls 83 . The top plate 81 is arranged above the turbine housing 59 . The rear plate 82 is arranged on the rear side of the vehicle 1 relative to the supercharger 9 and is formed to extend downward from the rear edge portion of the top plate 81 . The side wall 83 is provided so as to partially cover the end face 78A and is connected to the top plate 81 and the rear plate 82 .

The cover 80 guides air entering the engine compartment from a front grill formed on the front surface of the vehicle 1 to the turbine housing 59 of the supercharger 9A. The rear plate 82 and side walls 83 guide downward the air that has cooled the turbine housing 59 .

Here, the side wall 83 suppresses the flow of air heated to a high temperature by cooling the turbine housing 59 toward the PCU 6 side.

Furthermore, the side wall 83 can suppress the radiant heat radiated from the end surface 78A from being radiated to the outside, and can suppress the radiant heat radiated from the end surface 78A from reaching the PCU6.

A vehicle 1A according to the second embodiment will be described with reference to FIG. FIG. 8 is a plan view schematically showing the configuration of vehicle 1A according to the second embodiment. In this vehicle 1A, the supercharger 9B is provided in front of the internal combustion engine 2 in the longitudinal direction D of the vehicle.

The supercharger 9B also includes a compressor 55 , a turbine 56 , a shaft 57 , a compressor housing 58 , a turbine housing 59 and a bearing housing 60 .

Also in the supercharger 9B, the turbine 56 and the turbine housing 59 are located farther from the PCU 6 than the compressor 55 and the compressor housing 58 are. Therefore, in vehicle 1A as well, heat from turbine 56 and turbine housing 59 can be prevented from reaching PCU 6 .

The filter 63 is arranged on the front side of the vehicle 1A relative to the supercharger 9B, and the intake pipe 61 connects the filter 63 and the compressor housing 58 . The intercooler 65 is arranged on the upper surface of the internal combustion engine 2 , and the supply pipe 64 connects the intercooler 65 and the compressor housing 58 . Note that the intercooler 65 is connected to the intake manifold 50 .

An exhaust pipe 52 is connected to the turbine housing 59 , and the exhaust pipe 52 is connected to the exhaust manifold 51 . An exhaust pipe 68 is connected to the turbine housing 59 .

A catalyst member 71 and a catalyst member 72 are connected to the exhaust pipe 68 . Exhaust pipe 68 includes pipe 90 , pipe 91 , and pipe 92 . The pipe 90 is connected to the turbine housing 59 , extends from the turbine housing 59 in the vehicle width direction W, and is connected to the catalyst member 71 . Piping 91 is formed to extend downward from catalyst member 71 and is connected to catalyst member 72 .

The pipe 92 is connected to the catalyst member 72 and formed to extend from the catalyst member 72 toward the rear of the vehicle 1A.

In the vehicle 1A configured in this manner, the catalyst member 71, which tends to reach a high temperature, is arranged on the opposite side of the supercharger 9 from the PCU 6, so that the radiation heat from the catalyst member 71 is prevented from reaching the PCU 6. It is
