Description

  The present invention relates to a vehicle such as an automobile in which a power unit for burning an air-fuel mixture in an engine body and exhausting the mixture through an exhaust system member is enclosed by a capsule structure.

In automobiles, in recent years, development of electric vehicles using batteries and motors as power units has been promoted. However, full-scale commercialization of electric vehicles is left to future development.
For this reason, it is unlikely that the current and at least the near future will lose the use of the internal combustion engine that burns the mixture in the engine body, including hybrid vehicles.

JP, 2013-119384, A

By the way, when using the engine main body which burns air-fuel | gaseous mixture as a power unit, improving fuel consumption performance conventionally is calculated | required. For this purpose, it is conceivable to cover the engine body with a capsule structure as in Patent Document 1. Then, in Patent Document 1, the front inflow port of the capsule structure is controlled to be in the closed state at the time of initial start or key-off (Key-Off), and is controlled to be in the open state at the time of cooling while traveling. This allows the temperature of the engine body during shutdown to be maintained for a long time by means of the closed capsule structure, after which the engine body in the uncooled state can be restarted. By restarting the engine main body in the warmed state, it is possible to improve the fuel efficiency performance as compared with the case where the engine main body is restarted in the cooled state.
However, when covering with the capsule structure larger than the engine body in order to enclose the engine body as in Patent Document 1, the outside air blown into the atrioventricular chamber such as the front chamber of the vehicle is sprayed on the large wall by the capsule structure. As a result, the air resistance of the car is expected to be high. It is considered that the fuel efficiency performance in actual use may be reduced.

  As described above, in vehicles such as automobiles, it is required to improve the performance in practical use of a power unit including an engine body that burns air-fuel mixture.

  A vehicle having a capsule structure that encloses a power unit according to the present invention is at least at least the exhaust system member of a vehicle provided in a tuft chamber of the vehicle and having a power unit that burns air-fuel mixture with an engine body and exhausts through an exhaust system member. The capsule structure surrounding at least the engine body while being outside, the communication port formed on the side of the chamber of the vehicle and communicating the chamber with the inside of the wheel house, and movable so as to close the communication port A communication port opening / closing member that can be provided and a control unit that controls the opening / closing of the communication port by the communication port opening / closing member, the communication port opens on the rear side of the front surface of the capsule structure.

  Preferably, the exhaust system member is provided such that at least a portion thereof passes through the front side of the engine body or an oil pan projecting from the lower surface of the engine body, and the capsule structure or partition member is the exhaust system member It is preferable to divide between the rear engine body or the oil pan.

  Preferably, the capsule structure or the partition member has a guide surface which is inclined toward the communication port in the diagonally backward direction at an outer end of the vehicle in the vehicle width direction.

  Preferably, the control unit controls the communication port opening / closing member to open the communication port when the temperature of the exhaust system member reaches a predetermined temperature or more.

  Preferably, the capsule structure has an intake opening for taking in the outside air warmed by the exhaust system member, and an intake opening and closing member movably provided so as to close the intake opening. The control unit may control the communication opening and closing member to open the communication opening when the intake opening and closing member closes the intake opening in a state where the exhaust system member is warmed.

  Preferably, the capsule structure includes a cover case member surrounding at least the engine body in the vehicle, and the cover case member is attached to a frame member or a structural member of the vehicle together with the engine body. It should be supported.

  Preferably, the capsule structure encloses an oil lubricated device including at least the engine body in the vehicle.

  Preferably, the capsule structure encloses at least the engine body among the engine body, the engine accessory, the transmission, and the hybrid device provided in the vehicle.

  Preferably, the capsule structure is provided in the vehicle so as to bring an exhaust pipe, a turbo device, a muffler, and a catalyst device of the power unit out.

In the present invention, a capsule structure is provided in a chamber of a vehicle, and the capsule structure encloses at least an engine body of a vehicle having a power unit (with an air layer interposed therebetween). Thereby, the temperature of the engine body inside the capsule structure can be hardly changed. It is possible to suppress the deterioration of fuel consumption at the time of restart in a situation where the engine body is cooled.
In addition, a communication port for communicating the atrioventricular chamber with the inside of the wheel house is formed on the side surface of the atrioventricular chamber of the vehicle so as to open on the rear side of the front surface of the capsule structure. Therefore, the external air blown into the atrioventricular chamber in the atrioventricular chamber of the vehicle can be blown out of the atrioventricular chamber from the communication port. A part of the outside air blowing into the atrioventricular chamber can blow out of the atrioventricular chamber through the communication port after hitting the front of the capsule structure. In particular, by forming the communication port in the wheel house, the air in the chamber can be exhausted from the communication port by utilizing the negative pressure of the wheel house during traveling. As a result, although the capsule structure is provided in the atrioventricular region of the vehicle, the clogging of the outside air in the atrioventricular chamber can be suppressed, and the increase in the air resistance of the vehicle due to the capsule structure can be suppressed. It is possible to suppress the deterioration of the aerodynamics of the vehicle.
As a result, it is possible to improve the performance of the power unit including the engine body that burns the air-fuel mixture in actual use.

  Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is an explanatory view of a car 1 according to an embodiment of the present invention.
FIG. 2 is an explanatory view of a power unit provided in the automobile 1 of FIG.
The car 1 is an example of a vehicle. FIG. 1A is a side perspective view of a schematic automobile 1. FIG. 1 (B) is a front perspective view of a schematic car 1.

The automobile 1 of FIGS. 1 and 2 has a vehicle body 2. A front chamber 3 is provided at the front of the vehicle body 2. A pair of front beams 5 as frame members of the automobile 1 extend in the front chamber 3. Further, a toe board 6 as a partition (structural member) is provided between the front chamber 3 and the passenger compartment 4.
In the front chamber 3, a front chamber 3 in which power units such as an engine body 11 and a transmission 12 are disposed is provided. Further, a propeller shaft 13 is installed under the floor of the vehicle body 2 from the front chamber 3 toward the rear side of the vehicle body 2. At the rear end of the propeller shaft 13, a rear differential gear box 14 connected to a rear axle or wheel 15 is provided.
The engine main body 11 ignites and burns a mixture of the outside air and the gasoline taken in through the air cleaner 16 and the intake pipe 17 in the combustion chamber, and the expansion pressure of the burned mixture lowers the piston in the cylinder and is connected to the piston Rotate the output shaft. Also, the burned mixture is exhausted out through the open exhaust valve and exhaust pipe 18.
The rotational driving force of the output shaft generated by the engine body 11 is decelerated by the transmission 12 and transmitted to the rear wheel 15 through the propeller shaft 13, the rear differential gear box 14 and the rear axle shaft. Also, part of the rotational driving force is branched by the transmission 12 and transmitted to the front wheels 15 through a front axle shaft (not shown).
In FIG. 2 also, as a power unit provided in the automobile 1, an engine body 11, an oil pan 19, a radiator 20, an air cleaner 16, an intake pipe 17, an exhaust pipe 18, a turbo device 21, a catalyst device 22, a transmission 12, A propeller shaft 13 and a rear differential gear box 14 are illustrated.
The oil pan 19 is integrally formed with the engine body 11 at a lower portion of the engine body 11. The engine body 11 and the transmission 12 are devices lubricated by oil.
The radiator 20, the air cleaner 16, the intake pipe 17, the exhaust pipe 18, the turbo device 21 and the catalyst device 22 are engine accessories used together with the engine body 11. Although not shown in the drawings, the engine accessories are, for example, a generator, a battery, a distributor, an injector, a fuel tank, a pump and the like. These engine accessories are used together with the engine body 11 in order to assist the operation of the engine body 11 and to bring the state of the engine body 11 and the combustion state into a range suitable for combustion.

By the way, when using the engine main body 11 which burns air-fuel | gaseous mixture as a power unit, improving fuel consumption performance conventionally is calculated | required.
For this purpose, as shown in FIG. 1, it is conceivable to cover the engine body 11 with the covering case member 31.

FIG. 3 is an explanatory view of a covering case member 31 of a capsule device 30 provided so as to surround the power unit of FIG.
The capsule device 30 has a covering case member 31, an intake opening 32, and an intake opening and closing member 33.

The covering case member 31 has a substantially box shape and encloses the engine body 11 and the transmission 12 in which the oil pan 19 for the power unit is integrated. Covering case member 31 is formed of, for example, a heat insulating material. The covering case member 31 is formed in a box having a size slightly larger than the engine body 11 and the transmission 12. The propeller shaft 13, the intake pipe 17 and the exhaust pipe 18, which protrude outside from the covering case member 31, are formed of, for example, a rubber material or a resin material in order to ensure the hermeticity of the covering case member 31. Boots are provided.
Thus, the covering case member 31 encloses the surroundings of the engine main body 11 and the transmission 12 while securing an air layer between them. The injector and the oil pan 19 provided in the engine body 11 are also surrounded by the covering case member 31.
Further, substantially the entire exhaust pipe 18, the turbo device 21, the catalyst device 22, the air cleaner 16, and substantially the entire intake pipe 17 are provided outside the covering case member 31.
Note that engine accessories such as a generator, a battery, a distributor, a fuel tank, and a pump may be provided inside or outside the covering case member 31.
The cover case member 31 is mounted on and supported on the pair of front beams 5 of the vehicle body 2 at the same position as the engine body 11 in the front chamber 3 so as to overlap the engine body 11 as shown in FIG. . The covering case member 31 is provided so as not to project downward from the pair of front beams 5 as shown in FIG. 1 (B). The minimum ground clearance of the vehicle body 2 is the same as the case without the covering case member 31.

The intake opening 32 is formed in the lower front of the covering case member 31 as shown in FIG. The exhaust pipe 18 is provided to pass near the front side of the oil pan 19 on the lower side of the engine body 11.
Thus, the intake opening 32 is located between the oil pan 19 and the exhaust pipe 18 for the capsule device 30.

The intake opening and closing member 33 is integrally attached to the covering case member 31 on the upper and outer sides of the intake opening 32 of the covering case member 31. The intake opening and closing member 33 is provided to be rotatable upward with respect to the covering case member 31.
FIG. 3A shows a state in which the intake opening and closing member 33 is lowered. In this state, the intake opening 32 of the covering case member 31 is closed. The covering case member 31 is sealed, and the space inside the covering case member 31 can be separated from the outside.
FIG. 3B shows a state in which the intake opening and closing member 33 is raised. In this state, the intake opening 32 of the covering case member 31 is open. The inside and the outside of the covering case member 31 can communicate with each other through the intake opening 32.
Then, the intake opening / closing member 33 does not protrude downward relative to the covering case member 31 by rotatably attaching the intake opening / closing member 33 to the upper outside of the intake opening 32 of the covering case member 31 in this manner. It will be. As shown in FIG. 1, the intake opening / closing member 33 is provided inside so as not to project downward from the pair of front beams 5 of the vehicle body 2.

  Then, for example, based on the correlation between the temperature inside and outside of the covering case member 31 by the control unit 44 described later, the opening and closing of the intake opening 32 by the intake opening and closing member 33 is controlled.

By providing the covering case member 31 of the capsule device 30 as described above, the temperature of the stopped engine main body 11 is maintained for a long time by the closed covering case member 31, and thereafter the engine main body 11 is not cooled. It can be restarted. By restarting the engine main body 11 in the warmed state, it is possible to improve the fuel efficiency performance as compared with the case where the engine main body 11 is restarted in the cooled state.
Further, when the temperature of the oil pan 19 or the engine main body 11 rises, for example, to a temperature requiring warm air or more, the control unit 44 controls the intake opening and closing member 33 to open the intake opening 32. Thus, the outside air can be taken into the inside of the covering case member 31 and the oil pan 19 and the engine body 11 can be cooled.

However, when the power unit such as the engine body 11 is surrounded by the covering case member 31, the covering case member 31 is generally larger than the engine body 11. As a result, the outside air blown into the front chamber 3 of the automobile 1 is blown to the large wall by the covering case member 31. As a result, the air resistance of the automobile 1 is expected to increase. It is considered that the fuel efficiency performance in actual use may be reduced.
In particular, when the intake opening 32 is closed by the intake opening / closing member 33, the blowout path after blowing to the large wall by the covering case member 31 for the outside air blown into the front chamber 3 of the automobile 1 is lost. there is a possibility.
As described above, in the automobile 1 such as a vehicle, it is required to improve the performance of the power unit including the engine body 11 that burns the air-fuel mixture in actual use.

FIG. 4 is an explanatory view of a configuration of the covering case member 31 and its periphery in the front chamber 3 of the automobile 1 of FIG.
In the center of the front chamber 3 of the automobile 1, a covering case member 31 surrounding the engine body 11 and the transmission 12 is disposed. On both sides of the covering case member 31 in the vehicle width direction, wheel houses 23 formed on the side surfaces of the front chamber 3 are positioned.
The automobile 1 of FIG. 4 includes a communication port 41, a communication port opening and closing member 42, a temperature sensor 43, and a control unit 44.

The communication port 41 is formed at the corner between the front surface and the inner surface of the wheel house 23. The communication port 41 communicates the front chamber 3 with the inside of the wheel house 23.
The communication port 41 is located rearward of the front lower portion of the oil pan 19 with respect to the front surface of the capsule device 30. The communication port 41 is provided at the same height as the oil pan 19 and the intake opening 32.
The communication port 41 may be located on the rear side of the front surface of the capsule device 30, and may be provided on the front surface of the wheel house 23 or on the inner side surface of the wheel house 23. However, when the inner side surface of the wheel house 23 faces the cover case member 31, the inflow resistance to the communication port 41 may be increased. Further, the communication port 41 may be provided so as to be positioned from the front side to the rear side of the front surface of the capsule device 30.
Further, the communication port 41 may be provided at a position slightly higher than the oil pan 19 and the intake opening 32.

  The communication opening and closing member 42 is movably provided to close the communication opening 41. The communication opening and closing member 42 is attached to the wheel house 23 and integrally provided.

  The temperature sensor 43 is disposed near the exhaust pipe 18 in the front chamber 3 of the automobile 1 and detects the temperature of the exhaust pipe 18 as an external temperature.

The temperature sensor 43, the intake opening and closing member 33, and the communication opening and closing member 42 are connected to the control unit 44.
The control unit 44 controls the opening / closing of the communication port 41 by the communication port opening / closing member 42 in accordance with the state of the automobile 1.
Control unit 44 can be realized, for example, by a microcomputer. It may be provided by being attached to the covering case member 31 as a dedicated circuit, or may be provided as a function of an ECU (Engine Control Unit) that controls the automobile 1.

FIG. 5 is a flowchart of open / close control of the communication port 41 by the control unit 44 of FIG. 4.
The control unit 44 repeatedly executes open / close control of the communication port 41 of FIG. 5.

In the open / close control of FIG. 5, first, the control unit 44 acquires the external temperature from the temperature sensor 43 (step ST1).
Next, the control unit 44 compares the external temperature with the aeration temperature (step ST2). The aeration temperature may be, for example, a temperature at which the exhaust pipe 18 needs cooling.

  When the external temperature is equal to or higher than the ventilation temperature, the control unit 44 controls the communication opening and closing member 42 to open the communication opening 41 (step ST3).

  When the external temperature is lower than the ventilation temperature, the control unit 44 controls the communication opening and closing member 42 to close the communication opening 41 (step ST4).

As described above, in the present embodiment, the capsule device 30 is provided in the front chamber 3 of the automobile 1, and at least the engine body 11 of the automobile 1 having the power unit is spaced by the capsule device 30 to sandwich the air layer. Fence. Thereby, the temperature of the engine body 11 inside the capsule device 30 can be made difficult to change. It is possible to suppress deterioration in fuel consumption at the time of restart in a situation where the engine body 11 is cooled.
In addition, a communication port 41 communicating the front chamber 3 with the inside of the wheel house 23 is formed on the side surface of the front chamber 3 of the automobile 1 so as to be opened on the rear side of the front surface of the capsule device 30. Therefore, the flow path of the outside air blown into the front chamber 3 in the front chamber 3 of the automobile 1 can be blown out of the front chamber 3 from the communication port 41. In particular, by forming the communication port 41 in the front portion of the wheel house 23, the outside air blown into the front chamber 3 is made outside the front chamber 3 by utilizing the negative pressure in the front portion of the wheel house 23 during traveling. Can be evacuated to Moreover, in the front chamber 3, the gap between the wheel house 23 and the covering case member 31 becomes narrow, and the air pressure at that portion tends to be high due to the outside air that the outside air tries to blow. As a result, although the capsule device 30 is provided in the front chamber 3 of the automobile 1, the clogging of the outside air in the front chamber 3 can be suppressed, and the increase in the air resistance of the automobile 1 by the capsule device 30 can be suppressed. Deterioration of the aerodynamics of the automobile 1 can be suppressed.
As a result, it is possible to improve the performance in practical use of the power unit including the engine body 11 that burns the air-fuel mixture.

  In the present embodiment, at least a portion of the exhaust pipe 18 is provided to pass through the front side of the engine body 11 or the oil pan 19 projecting from the lower surface of the engine body 11. A capsule device 30 is provided so as to partition between the oil reservoir 11 and the oil pan 19. Therefore, it is difficult to directly supply the engine body 11 or the oil pan 19 with the outside air warmed by the exhaust pipe 18 which has high heat. The engine main body 11 or the oil pan 19 in operation can be hardly heated by the heat of the exhaust pipe 18.

  In the present embodiment, when the exhaust pipe 18 reaches a predetermined temperature or more, the control unit 44 controls the communication opening and closing member 42 to open the communication opening 41. Therefore, the heat of the exhaust pipe 18 can be exhausted from the communication port 41 to the outside of the front chamber 3.

  In the present embodiment, the capsule device 30 is configured by the covering case member 31 that encloses at least the engine main body 11 in the front chamber 3 of the automobile 1. Then, the covering case member 31 is attached to and supported by the frame member or the structural member of the automobile 1 at the same position as the engine main body 11 so as to overlap the engine main body 11. Therefore, it is not necessary to attach the member of the capsule device 30 separately from the power unit such as the engine main body 11 to the frame member or structural member of the automobile 1. Compared with the case where the capsule device 30 is configured with a covering member such as an engine cover or an undercover attached uniquely to, for example, a frame member or a structural member of the automobile 1, a large scale countermeasure or change is required on the automobile 1 side. And not. In addition, since the capsule device 30 itself can be made smaller, the capsule device 30 itself can be manufactured inexpensively.

  Although the above-mentioned embodiment is an example of a suitable embodiment of the present invention, the present invention is not limited to this, and various modification or change is possible in the range which does not deviate from the gist of an invention.

For example, in the above embodiment, the lower front surface of the covering case member 31 is formed in a plane extending in the vehicle width direction at the same height position as the communication port 41.
FIG. 6 is an explanatory view of a modification of the covering case member 31 of FIG.
In FIG. 6, the cover case member 31 is formed with guide surfaces 51 at both left and right ends in the vehicle width direction with respect to the front lower portion.
The guide surface 51 is inclined toward the communication port 41 in the diagonally backward direction.
By providing such a guide surface 51, the outside air warmed by the exhaust pipe 18 having high heat can flow along the guide surface 51 and can be exhausted from the communication port 41 after hitting the front surface of the covering case member 31. . From the inclined guide surface 51 along the front surface of the capsule device 30, the fluid flows smoothly toward the communication port 41. Outside air may be disturbed and stagnant in the capsule device 30 and its surroundings.

FIG. 7 is a flowchart of a modification of the opening / closing control of the communication port 41 of FIG.
In FIG. 7, when the external temperature is equal to or higher than the ventilation temperature in step ST2, the control unit 44 determines the open / close state of the intake opening 32 of the capsule device 30 (step ST11). When the intake opening 32 is closed, the communication opening / closing member 42 is controlled to open the communication opening 41 (step ST3). On the other hand, when the intake opening 32 is open, the communication opening / closing member 42 is controlled to close the communication opening 41 (step ST4).
As described above, when the intake opening 32 is open, the communication port 41 is closed, so that the outside air flowing into the front chamber 3 can be prevented from flowing into the covering case member 31.
Further, when the capsule device 30 is closed, the heat of the exhaust pipe 18 can be exhausted from the communication port 41 to the outside of the front chamber 3.

FIG. 8 is an explanatory view of a power unit and a capsule device 30 in a hybrid vehicle.
In FIG. 8, an electric motor 61 is attached to the transmission 12. A plurality of battery cells are connected to the electric motor 61 through a converter (not shown). By driving the electric motor 61, the driving force can be transmitted to the propeller shaft 13 through the transmission 12.
In the case of the configuration of such a power unit, the covering case member 31 of the capsule device 30 may be provided together with the engine body 11, the engine accessory and the transmission 12 so as to surround the electric motor 61 as a hybrid device and the converter. In this case, it is possible to warm the electric motor 61 and the converter so that frictional resistance and the like are in a state suitable for operation. In addition, the inside of the covering case member 31 may be divided into two chambers, one of which houses the engine main body 11 and the like, and the other of which houses the hybrid device. In this case, it is also possible to keep each room at a separate temperature.

In the above embodiment, the front lower portion of the covering case member 31 of the capsule device 30 is at the same height position as the through hole.
In addition to this, for example, a partition plate may be provided downward from the covering case member 31, and the partition plate may be at the same height position as the through hole. Moreover, you may form the guide surface 51 in the vehicle width direction both ends about a partition plate. Like the cover case member 31, such a partition plate divides between the exhaust pipe 18 and the rear engine body 11 or the oil pan 19 at the same height position as the communication port 41 or at a position slightly above the communication port 41. I can do it.
