Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an internal combustion engine provided with a heat storage device.
[0002]
[Prior art]
An internal combustion engine is required to improve startability, reduce fuel consumption, improve exhaust emission, and the like when cold. Therefore, in order to meet these demands, a technology of a heat storage device is known as a technology for warming the engine at an early stage (see, for example, Patent Documents 1 and 2). This is a technique using a cooling liquid in a cooling device. In other words, a part of the cooling liquid warmed during engine operation is stored in a heat storage tank in a state of being kept warm even after the engine is stopped, and this warmed cooling liquid is returned to the engine before the engine is started (hereinafter referred to as the technology). The operation of returning the warmed cooling liquid to the engine before starting the engine is called preheating).
[0003]
With reference to FIG.6 and FIG.7, an example of the internal combustion engine provided with the heat storage apparatus which concerns on a prior art is demonstrated. 6 and 7 are schematic views of an internal combustion engine provided with a heat storage device according to the prior art. The arrows in FIG. 6 indicate the flow of the cooling liquid as the heat medium during preheating. The arrows in FIG. 7 indicate the flow of the cooling liquid during engine operation.
[0004]
As shown in the figure, an internal combustion engine provided with a heat storage device is a state in which an engine main body 110 having a cylinder head 111 and a cylinder block 112 and a part of a cooling liquid as a heat medium heated by the engine main body 110 are kept warm. A heat storage tank 120 for storing, an electric pump 121 for flowing cooling liquid, a pump 130 driven by a belt (not shown) provided in the engine body 110, a heater core 141 used for heating the vehicle interior, A throttle body 142 having a throttle valve interlocking with the accelerator and a throttle position sensor for detecting the opening thereof, and a three-way valve 150 for switching a path through which the cooling liquid flows are provided.
[0005]
With the above configuration, the electric pump 121 is turned on during preheating. At this time, the valve on the heater core 141 side of the three-way valve 150 is closed. As a result, as shown in FIG. 6, the cooling liquid flows through a path that circulates through the heat storage tank 120, the engine body 110, and the throttle body 142. Accordingly, the warm cooling liquid stored in the heat storage tank 120 is supplied to the engine body 110 and the throttle body 142. As described above, since the engine body 110 and the throttle body 142 are warmed before the engine is started, warm-up is promoted. Thereafter, the electric pump 121 is turned off and the preheating is finished.
[0006]
During engine operation, the pump 130 is driven. At this time, the valve on the heat storage tank 120 side of the three-way valve 150 is closed. As a result, as shown in FIG. 7, the cooling liquid flows through a path that circulates through the engine body 110, the heater core 141, and the throttle body 142. Accordingly, the cooling liquid heated by the engine body 110 is supplied to the heater core 141 and the throttle body 142. As described above, the heater core 141 and the throttle body 142 are heated, and the heat of the cooling liquid is taken away by the heater core 141 and the throttle body 142.
[0007]
By the way, in the internal combustion engine provided with the heat storage device, it is desirable that the capacity of the heat storage tank is as small as possible from the viewpoint of mounting space and cost. In this connection, in the preheating, it is desirable to supply the warm cooling liquid intensively to the part to be warmed so that the part to be warmed can be efficiently warmed. In general, it is desirable to supply a warm cooling liquid only to the engine body during preheating. However, in the case of the internal combustion engine provided with the heat storage device shown in FIGS. 6 and 7, warm cooling liquid is also supplied to the throttle body 142 during preheating. Therefore, this internal combustion engine does not satisfy the above requirements.
[0008]
As a technique that satisfies the above requirements, there is a technique in which means for controlling the flow of the cooling liquid (electromagnetic valve, three-way valve, etc.) is provided for each of the paths through which the cooling liquid flows (see, for example, Patent Document 1). . Thereby, at the time of preheating, a cooling liquid can be flowed only to the circulation path which circulates through an engine main body and a thermal storage tank. For example, in the case of the examples shown in FIGS. 6 and 7, if a control valve such as a three-way valve is also provided at the position indicated by X in the figure, at the time of preheating, only the circulation path that circulates between the engine body and the heat storage tank is provided. Cooling liquid can flow. However, when a plurality of means for controlling the flow of the cooling liquid are provided in this way, the number of parts increases and the control becomes complicated. As a result, the cost increases.

Furthermore, one of the objects of the present invention is to improve the heating efficiency.
[0015]
[Means for Solving the Problems]
The present invention employs the following means in order to solve the above problems.
[0016]
The internal combustion engine provided with the heat storage device of the present invention includes a circulation path that passes through the heat storage tank and a plurality of members to be supplied to which a heat medium is supplied. And in this invention, about the supply control of a heat medium among several to-be-supplied members, the structure which controls collectively was employ | adopted about what can perform the same control. That is, the supply control of the heat medium can be simultaneously performed on a plurality of supplied members by a single control means. With the configuration of the present invention, the number of parts can be reduced. Moreover, simplification of control can be achieved. These also contribute to cost reduction.
[0017]
As a more specific internal combustion engine equipped with the heat storage device of the present invention,
A heat storage tank in which the heat medium warmed by the engine is kept warm,
In the internal combustion engine including a heat storage device having the heat storage tank and a circulation path that circulates through the engine body,
A plurality of supplied members including at least a first supplied member and a second supplied member to which a heat medium is supplied;
And a single control means for performing supply control of the heat medium to the first supplied member and the second supplied member.
[0018]
According to the configuration of the present invention, the supply control of the heat medium can be simultaneously performed on the first supplied member and the second supplied member by a single control unit. Therefore, the number of parts can be reduced. Moreover, simplification of control can be achieved. These also contribute to cost reduction.
[0019]
Note that the “supply control” includes not only control for switching between supply of heat medium and stop of supply, but also control of the supply amount of the heat medium. And as a control means, the control valve which can control opening and closing of a valve can be mentioned, for example. In the case of this control valve, it is possible to perform control to switch between supply of the heat medium and stop of supply to the first supplied member and the second supplied member by opening / closing control of the valve. Further, the supply amount of the heat medium can be controlled by adjusting the degree of opening of the valve by the control valve. The control means may include a switching valve that switches a path through which the heat medium flows. In the case of this switching valve, it is possible to control whether to supply the heat medium or to stop the supply to the first supplied member and the second supplied member by switching the flow path of the heat medium. it can. Moreover, the supply amount of the heat medium can be controlled by incomplete switching without completely switching the path through which the heat medium flows by the switching valve.
[0020]
Here, regarding the supply control of the heat medium, the same control may be performed on the first supplied member and the second supplied member by the control means. That is, there is a case where some of the supplied members can perform the same control regarding the supply control of the heat medium. Therefore, in the present invention, the same control is performed collectively.
[0021]
The supply control may be performed based on a warm-up request for the first supplied member and the second supplied member. That is, the same control is performed on the first supplied member and the second supplied member that require warm-up.
[0022]
The first supplied member and the second supplied member may be provided in parallel in the heat medium supply path.
[0023]
If it does in this way, the heat exchange in one to-be-supplied member will not affect the heat exchange in the other to-be-supplied member.
[0024]
A first circulation path that circulates between the heat storage tank and the engine body without passing through the first supplied member and the second supplied member;
A second circulation path that circulates through the first and second supplied members and the engine body without passing through the heat storage tank;
The control means may be capable of switching a path through which the heat medium flows to the first circulation path or the second circulation path.
[0025]
In this way, when the heat medium circulates through the first circulation path, the heat medium does not pass through the first supplied member and the second supplied member. Accordingly, the warm heat medium stored in the heat storage tank can be intensively supplied to the engine main body without being supplied to the first supplied member and the second supplied member. Therefore, the heat storage tank can be reduced in size because the heat medium is not supplied to the first supplied member and the second supplied member. Further, the heating efficiency of the engine body can be improved. Further, when the heat medium circulates through the second circulation path, the heat medium does not pass through the heat storage tank. Therefore, for example, it is possible to prevent the cooled heat medium from being supplied from the heat storage tank to the engine body immediately after the engine is started. In the second circulation path, the first supplied member and the second supplied member include cases where they are arranged in series and arranged in parallel.
[0026]
The engine body further includes a third circulation path that circulates the first supplied member and the second supplied member and the heat storage tank without passing through the engine body,
The control means may be capable of switching the path through which the heat medium flows to any one of the first circulation path, the second circulation path, and the third circulation path.
[0027]
In this way, when the heat medium circulates through the third circulation path, the heat medium does not pass through the engine body. Thereby, the warm heat medium stored in the heat storage tank can be intensively supplied to the first supplied member and the second supplied member. In the third circulation path, the first supplied member and the second supplied member include cases where they are arranged in series and arranged in parallel.
[0028]
In addition, an electric pump is provided in the common part of the first circulation path and the third circulation path,
A pump having the engine body as a drive source may be provided in the second circulation path.
[0029]
With this configuration, the warm heat medium stored in the heat storage tank can be supplied to the engine main body or the first supplied member and the second supplied member by the electric pump before starting the engine. . Further, during engine operation, the pump is operated by the driving force from the engine body, and the heat medium circulates through the second circulation path.
[0030]
The control means may be a three-way valve capable of switching a path through which the heat medium flows in three directions.
[0031]
Thereby, switching of three circulation paths can be performed reliably.
[0032]
The first supplied member may be a heater core, and the second supplied member may be a throttle body.
[0033]
In addition, said each structure can be employ | adopted combining as much as possible.

However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. Absent.
[0035]
(First embodiment)
With reference to FIGS. 1-3, the internal combustion engine provided with the thermal storage apparatus which concerns on the 1st Embodiment of this invention is demonstrated. FIG.1 and FIG.2 is a schematic diagram of the internal combustion engine provided with the heat storage apparatus which concerns on the 1st Embodiment of this invention. The arrows in FIG. 1 indicate the flow of the cooling liquid as the heat medium during preheating. The arrows in FIG. 2 indicate the flow of the cooling liquid during engine operation. FIG. 3 is a schematic view further simplifying the internal combustion engine provided with the heat storage device shown in FIGS.
[0036]
<Schematic configuration of an internal combustion engine provided with a heat storage device>
As shown in the figure, an internal combustion engine provided with a heat storage device according to the present embodiment includes an engine body 10 having a cylinder head 11 and a cylinder block 12, and a part of a cooling liquid as a heat medium heated by the engine body 10. Are stored in a state of being kept warm, an electric pump 21 for causing the cooling liquid to flow, and a pump 30 driven by a belt (not shown) provided in the engine body 10. In addition, the internal combustion engine provided with the heat storage device according to the present embodiment further detects the heater core 41 as a first supplied member used for heating the passenger compartment, the throttle valve linked to the accelerator, and the opening thereof. A throttle body 42 as a second supplied member having a throttle position sensor and a three-way valve 50 for switching a path through which the cooling liquid flows are provided.
[0037]
As shown in FIG. 3, the heater core 41 and the throttle body 42 do not pass, the first circulation path R1 that circulates between the engine body 10 and the heat storage tank 20, and the heat storage tank 20 does not pass, and the engine body 10 and the heater core A second circulation path R2 that circulates 41 and the throttle body 42 and a third circulation path R3 that circulates the heat storage tank 20, the heater core 41, and the throttle body 42 without passing through the engine body 10 are formed. In the present embodiment, the heater core 41 and the throttle body 42 are arranged in parallel in the second circulation path R2 and the third circulation path R3.
[0038]
The three-way valve 50 also functions as a control unit that controls the supply of cooling liquid to the heater core 41 and the throttle body 42. As shown in FIG. 3, the three-way valve 50 is disposed at a branch portion of the first circulation path R1, the second circulation path R2, and the third circulation path R3. The three-way valve 50 can selectively close the first valve V1 on the heater core 41 and the throttle body 42 side, the second valve V2 on the heat storage tank 20 side, or the third valve V3 on the engine body 10 side. Thus, when the first valve V1 of the three-way valve 50 is closed, the cooling liquid can be circulated only in the first circulation path R1. When the second valve V2 of the three-way valve 50 is closed, the cooling liquid can circulate only in the second circulation path R2. Further, when the third valve V3 of the three-way valve 50 is closed, the cooling liquid can be circulated only in the third circulation path R3.
[0039]
<Operation of internal combustion engine equipped with heat storage device (during preheating)>
FIG. 1 shows the operating state during preheating, and the arrows in the figure show the flow of the cooling liquid at that time. Preheating is performed in order to warm up the engine in advance and promote warm-up before starting the engine. This preheating is started in response to a preheat trigger signal such as a door switch signal. That is, the electric pump 21 is turned on in response to the preheat trigger signal. The three-way valve 50 closes the first valve V1. As a result, a flow in which the cooling liquid circulates as shown in the figure. In FIG. 3, the cooling liquid circulates through the first circulation path R1 counterclockwise in the drawing. At this time, since the three-way valve 50 closes the first valve V1, there is no flow of the cooling liquid circulating in the other circulation paths. Thereafter, the electric pump 21 is turned off, the flow of the cooling liquid is stopped, and the preheating is finished.
[0040]
Here, only the warm cooling liquid stored in the heat storage tank 20 is supplied to the engine main body 10 and the cooled cooling liquid in the engine main body 10 passes through the heat storage tank 20 during the time that the electric pump 21 is turned on. The setting is made so as not to return to the engine body 10 again. As described above, the engine main body 10 can be warmed by the warm cooling liquid stored in the heat storage tank 20 at the time of cold before the engine is started. Therefore, the amount of fuel adhering to the inner wall surface of the intake pipe can be reduced early. In addition, since the volatility of the fuel is increased early, the ignitability of the air-fuel mixture can be improved and the combustion can be stabilized. From the above, it is possible to improve startability during cold start, reduce fuel consumption, and improve exhaust emission.
[0041]
<Operation of Internal Combustion Engine with Heat Storage Device (During Engine Operation)>
FIG. 2 shows the operating state during engine operation, and the arrows in the figure indicate the flow of the cooling liquid at that time. After the preheating is completed, the pump 30 is activated by starting the engine. The three-way valve 50 closes the first valve V2. As a result, a flow in which the cooling liquid circulates as shown in the figure. In FIG. 3, the cooling liquid circulates through the second circulation path R2 in the clockwise direction in the drawing. At this time, since the electric pump 21 is not operated and the three-way valve 50 closes the first valve V2, there is no flow of cooling liquid circulating through the other circulation paths.
[0042]
A warm-up operation is performed for a while after the engine operation is started, and then a normal operation is performed. Here, the heater core 41 and the throttle body 42 exhibit a heat exchange function. Therefore, when the engine is in operation, the cooling liquid is supplied to the heater core 41 and the throttle body 42, so that these temperatures increase, while the cooling liquid temperature decreases. The reason for heating the heater core 41 is to heat the passenger compartment. The reason for heating the throttle body 42 is to prevent moisture contained in the intake air from icing on the intake passage. Further, during normal engine operation, heat exchange is performed by the heater core 41, the throttle body 42, and a radiator (not shown) through the cooling liquid, and the engine is maintained at an appropriate temperature.
[0043]
Then, during engine operation or after engine operation is stopped, the electric pump 21 is turned on at an appropriate timing to form a flow of cooling liquid that circulates through the first circulation path R1 shown in FIG. Thereby, the cooling liquid which became high temperature is stored in the heat storage tank 20, and it prepares for the next preheating.
[0044]
<Effect obtained by internal combustion engine provided with heat storage device according to the present embodiment>
As described above, the heater core 41 and the throttle body 42 are members that are required to be warmed up for heating the passenger compartment in the former case and for preventing freezing in the intake passage in the latter case. is there. However, these warm-up priorities are usually lower than the warm-up priorities of the engine body 10. Therefore, in preheating, it is desirable to warm only the engine body 10 and preferentially promote the warm-up of the engine body 10. Normally, it is sufficient that the heater core 41 and the throttle body 42 are warmed up after the engine is started. The heater core 41 and the throttle body 42 have the same priority for warming up, and the timing for requesting warming up is also the same. Therefore, the supply control of the cooling liquid to these can be made the same. Therefore, in the present embodiment, as described above, the same cooling liquid supply control is performed on the heater core 41 and the throttle body 42 by switching the circulation path of the cooling liquid using the single three-way valve 50. Configured to do. Here, “cooling liquid supply control” means control for switching between supply of the cooling liquid and stop of supply.
[0045]
As described above, in the present embodiment, the same cooling liquid supply control can be performed on the heater core 41 and the throttle body 42 by using the three-way valve 50 as a single control means. Therefore, the number of parts can be reduced as compared with the case where the control unit is provided separately to control the supply of the cooling liquid. Further, the control can be simplified as compared with the case where the control is performed separately. Furthermore, these contribute to cost reduction.
[0046]
In the present embodiment, during the preheating, the warm cooling liquid stored in the heat storage tank 20 is supplied only to the engine body 10 and not supplied to the heater core 41 and the throttle body 42. Therefore, since the supply amount of the warm cooling liquid can be small, the heat storage tank 20 can be downsized. In preheating, the heating efficiency of the engine body 10 can be improved. In the present embodiment, the heater core 41 and the throttle body 42 are provided in parallel in the cooling liquid supply path. Therefore, one heat exchange does not affect the other heat exchange. That is, when the heater core 41 and the throttle body 42 are arranged in series, the cooling liquid is supplied to the one arranged upstream. Therefore, there is a possibility that the heat disposed in the downstream side is not sufficiently exchanged. On the other hand, such a problem does not occur by arranging the heater core 41 and the throttle body 42 in parallel as in the present embodiment.
[0047]
Further, in the present embodiment, it is possible to control the cooling liquid to circulate through the third circulation path R3 by closing the third valve V3 of the three-way valve 50. Therefore, for example, under the environment such as cold and humid, it may be considered that the warming up of the heater core 41 and the throttle body 42 is prioritized over the engine body 10. In such a case, warm-up of the heater core 41 and the throttle body 42 can be preferentially promoted by controlling the cooling liquid to circulate through the third circulation path R3 in the preheating. Thus, in the present embodiment, a wide variety of supply control of the cooling liquid can be performed using the single three-way valve 50.
[0048]
(Second Embodiment)
FIG. 4 shows a second embodiment of the present invention. In the present embodiment, a case where the circulation path is different from that of the first embodiment will be described. Since the basic constituent members and the operation thereof are the same as those of the first embodiment, the same constituent parts are denoted by the same reference numerals, and the description thereof is omitted.
[0049]
FIG. 4 is a schematic diagram of an internal combustion engine provided with a heat storage device according to the second embodiment of the present invention. In the present embodiment, the valve that switches the path through which the cooling liquid flows is a two-way valve 51, unlike the first embodiment. The other parts of the engine body 10, the heat storage tank 20, the electric pump 21, the pump 30, the heater core 41, and the throttle body 42 are the same as those in the first embodiment. However, these arrangements differ from the case of the first embodiment, and the circulation path of the cooling liquid is different.
[0050]
In the present embodiment, the cooling liquid does not pass through the heater core 41 and the throttle body 42 when the first valve V1 of the two-way valve 51 is closed, the electric pump 21 is turned on, and the pump 30 is not operated. Then, it circulates through the first circulation path R11 that circulates between the engine body 10 and the heat storage tank 20 (circulates in the direction of the dashed-dotted arrow in the figure). In the state where the second valve V2 of the two-way valve 51 is closed, the electric pump 21 is turned off, and the pump 30 is operated, the cooling liquid is the engine body 10, the throttle body 42, the heater core 41, and It circulates through 2nd circulation path | route R12 which circulates through the thermal storage tank 20 (circulates in the direction of the arrow of the dotted line in the figure). Thus, in the present embodiment, in the case of preheating, control is performed so that the cooling liquid circulates through the first circulation path R11, and the cooling liquid circulates through the second circulation path R12 during engine operation. To control.
[0051]
As described above, also in the present embodiment, the same cooling liquid supply control can be performed on the heater core 41 and the throttle body 42 using the single two-way valve 51. Therefore, as in the case of the first embodiment, it is possible to reduce the number of parts, simplify the control, and reduce the cost. Also in the present embodiment, during preheating, the warm cooling liquid stored in the heat storage tank 20 is supplied only to the engine body 10 and not supplied to the heater core 41 and the throttle body 42. Therefore, as in the case of the first embodiment, the heat storage tank 20 can be downsized and the heating efficiency of the engine body 10 can be improved.
[0052]
(Third embodiment)
FIG. 5 shows a third embodiment of the present invention. The present embodiment is the same as the second embodiment except that the heater core 41 and the throttle body 42 are provided in parallel in the cooling liquid supply path. The same components as those in the second embodiment are denoted by the same reference numerals, and description thereof is omitted.
[0053]
FIG. 5 is a schematic view of an internal combustion engine provided with a heat storage device according to a third embodiment of the present invention.
[0054]
Also in the present embodiment, when the first valve V1 of the two-way valve 51 is closed, the electric pump 21 is turned on, and the pump 30 is not operated, the cooling liquid passes through the heater core 41 and the throttle body 42. Instead, it circulates through the first circulation path R21 that circulates between the engine body 10 and the heat storage tank 20 (circulates in the direction of the dashed-dotted arrow in the figure). In the state where the second valve V2 of the two-way valve 51 is closed, the electric pump 21 is turned off, and the pump 30 is operated, the cooling liquid is the engine body 10, the heater core 41, the throttle body 42, and It circulates through 2nd circulation path | route R22 which circulates through the thermal storage tank 20 (circulates in the direction of the arrow of the dotted line in the figure). Thus, also in the present embodiment, in the case of preheating, control is performed so that the cooling liquid circulates through the first circulation path R11, and the cooling liquid circulates through the second circulation path R12 during engine operation. To control. In the present embodiment, the heater core 41 and the throttle body 42 are provided in parallel in the cooling liquid supply path.
[0055]
As described above, it goes without saying that the present embodiment can achieve the same effects as those of the second embodiment. In the case of the present embodiment, the heater core 41 and the throttle body 42 are provided in parallel in the cooling liquid supply path, so that one heat exchange does not affect the other heat exchange.
[0056]
【The invention's effect】
As described above, according to the present invention, the number of parts can be reduced, the control can be simplified, and the cost can be reduced. Moreover, according to this invention, size reduction of a thermal storage tank and improvement of a heating efficiency can be aimed at.
