Description

本発明は、内燃機関のシリンダヘッドにおける冷却水が流出する流出口に対し、冷却水を他の機器へと導く配管、冷却水の温度を検出する水温センサ、及び冷却水に混入した気体を冷却水から分離させるバルブを組み付けるためのハウジングに関する。 The present invention cools a pipe that guides the cooling water to another device, a water temperature sensor that detects the temperature of the cooling water, and a gas mixed in the cooling water to the outlet where the cooling water flows out in the cylinder head of the internal combustion engine. Regarding the housing for assembling the valve that separates from water.

車両、特に四輪自動車の内燃機関は、一般に水冷式になっている。内燃機関から流出する高温の冷却水は、車室内を空調するエアコンディショナの暖房用の熱源として利用される。即ち、内燃機関のシリンダブロック及びシリンダヘッドを通過した冷却水を熱交換器であるヒータコアに導き、その冷却水と車室内に供給される空気との間で熱交換を行い、車室内を暖房する。 Internal combustion engines of vehicles, especially four-wheeled vehicles, are generally water-cooled. The high-temperature cooling water flowing out of the internal combustion engine is used as a heat source for heating the air conditioner that air-conditions the passenger compartment. That is, the cooling water that has passed through the cylinder block and cylinder head of the internal combustion engine is guided to the heater core, which is a heat exchanger, and heat is exchanged between the cooling water and the air supplied to the passenger compartment to heat the passenger compartment. ..

また、近時では、内燃機関及び電動機の二つの動力源を備えるハイブリッド車両が一定の普及を見ている。シリーズ方式のハイブリッド車両は、内燃機関により発電機を駆動して発電を行い、発電した電力を蓄電装置（バッテリ及び／またはキャパシタ）に蓄えるとともに電動機に供給する。そして、この電動機によって車両の車軸、ひいては駆動輪を回転させて走行する（以上、例えば下記特許文献を参照）。 Recently, hybrid vehicles equipped with two power sources, an internal combustion engine and an electric motor, have seen a certain degree of widespread use. In the series hybrid vehicle, a generator is driven by an internal combustion engine to generate electricity, and the generated power is stored in a power storage device (battery and / or capacitor) and supplied to an electric motor. Then, the electric motor rotates the axle of the vehicle, and by extension, the drive wheels to travel (see, for example, the following patent documents).

特開２０１９−１３１０３５号公報Japanese Unexamined Patent Publication No. 2019-131035

図５に模式的に示すように、シリンダヘッド５の外面５１には冷却水の流出口５２が開設され、その流出口５２に冷却水をヒータコアへと導く配管（ホース及び／またはパイプ）２や、冷却水を空冷する熱交換器であるラジエータへと導く配管０が接続される。加えて、シリンダヘッド５内の冷却水の温度を検出する水温センサ３も取り付けられる。そして、既存の内燃機関６では、シリンダヘッド５からヒータコアに向かう配管２と、水温センサ３の出力信号を伝送するリード線（または、ハーネス）３１とが同一方向に、より具体的にはシリンダヘッド５の外面５１が向く方向、換言すれば内燃機関６のリア方向に伸長していた。 As schematically shown in FIG. 5, a cooling water outlet 52 is provided on the outer surface 51 of the cylinder head 5, and a pipe (hose and / or pipe) 2 and a pipe (hose and / or pipe) 2 for guiding the cooling water to the heater core are provided at the outlet 52. , The pipe 0 that leads to the radiator, which is a heat exchanger that cools the cooling water by air, is connected. In addition, a water temperature sensor 3 that detects the temperature of the cooling water in the cylinder head 5 is also attached. Then, in the existing internal combustion engine 6, the pipe 2 from the cylinder head 5 to the heater core and the lead wire (or harness) 31 for transmitting the output signal of the water temperature sensor 3 are in the same direction, more specifically, the cylinder head. It extended in the direction in which the outer surface 51 of 5 was directed, in other words, in the rear direction of the internal combustion engine 6.

他方、図６に模式的に示すように、ハイブリッド車両では、内燃機関６の他に電動機や発電機、電力制御を担うＰＣＵ（Ｐｏｗｅｒ Ｃｏｎｔｒｏｌ Ｕｎｉｔ）７等をエンジンルーム（エンジンコンパートメント）に収容する必要が生じる。図示例のように、内燃機関６及びＰＣＵ７、ＥＣＵ（Ｅｌｅｃｔｒｏｎｉｃ Ｃｏｎｔｒｏｌ Ｕｎｉｔ）８、リレーボックス９その他を車両の左右方向に沿って配列する態様では、内燃機関６のシリンダヘッド５のリア側の外面５１から突出する配管２やリード線３１がＰＣＵ７と干渉し得るため、内燃機関６とＰＣＵ７との間に一定以上の幅のクリアランスＣを設ける必要がある。 On the other hand, as schematically shown in FIG. 6, in a hybrid vehicle, in addition to the internal combustion engine 6, it is necessary to accommodate an electric motor, a generator, a PCU (Power Control Unit) 7 responsible for power control, and the like in an engine room (engine compartment). Occurs. As shown in the illustrated example, in the embodiment in which the internal combustion engine 6, the PCU 7, the ECU (Electronic Control Unit) 8, the relay box 9, and the like are arranged along the left-right direction of the vehicle, the outer surface 51 on the rear side of the cylinder head 5 of the internal combustion engine 6 Since the pipe 2 and the lead wire 31 protruding from the internal combustion engine 6 may interfere with the PCI7, it is necessary to provide a clearance C having a certain width or more between the internal combustion engine 6 and the PCI7.

しかしながら、小型の車両では、車両の左右方向に沿ったエンジンルームの内容積を拡大することに限界があり、十分なクリアランスを確保することが難しい。 However, in a small vehicle, there is a limit to expanding the internal volume of the engine room along the left-right direction of the vehicle, and it is difficult to secure a sufficient clearance.

また、特定の車種に特化した内燃機関やＰＣＵを新たに設計開発することは、経済合理性を含めて決して容易ではなく、内燃機関及びＰＣＵについてはどうしても既存のものを流用せざるを得ない。即ち、内燃機関またはＰＣＵの外寸を縮小することも現実的に難しい。 In addition, it is not easy to newly design and develop an internal combustion engine or PCU specialized for a specific vehicle model, including economic rationality, and the existing internal combustion engine and PCU must be diverted. .. That is, it is practically difficult to reduce the outer dimensions of the internal combustion engine or PCU.

本発明は、内燃機関のシリンダヘッドから伸長する配管やリード線がエンジンルームの内容積を圧迫する問題を回避することを所期の目的としている。 An object of the present invention is to avoid the problem that the pipes and lead wires extending from the cylinder head of the internal combustion engine press the internal volume of the engine room.

上述した課題を解決するべく、本発明では、内燃機関のシリンダヘッドにおける冷却水が流出する流出口に対して、冷却水を他の機器へと導く配管、冷却水の温度を検出する水温センサ、及び冷却水に混入した気体を冷却水から分離させるバルブを組み付けるためのものであって、シリンダヘッドの流出口に連通するとともにシリンダヘッドにおける流出口が開口している外面と略平行に伸び出して前記配管が取り付けられる配管取付部と、シリンダヘッドの流出口に連通するとともにシリンダヘッドにおける流出口が開口している外面と略平行かつ前記配管取付部が伸びる方向とは異なる方向に伸び出して前記水温センサが取り付けられるセンサ取付部と、シリンダヘッドの流出口に連通するとともにシリンダヘッドにおける流出口が開口している外面と略平行かつ前記配管取付部及び前記センサ取付部が伸びる方向とは異なる方向に伸び出して前記バルブが取り付けられるバルブ取付部とを具備する組付用ハウジングを採用した。 In order to solve the above-mentioned problems, in the present invention, a pipe that guides the cooling water to another device, a water temperature sensor that detects the temperature of the cooling water, and a water temperature sensor that guides the cooling water to another device at the outlet where the cooling water flows out in the cylinder head of the internal combustion engine. And for assembling a valve that separates the gas mixed in the cooling water from the cooling water, it communicates with the outlet of the cylinder head and extends substantially parallel to the outer surface where the outlet of the cylinder head is open. The pipe mounting portion to which the pipe is mounted communicates with the outlet of the cylinder head and extends substantially parallel to the outer surface of the cylinder head where the outlet is open and extends in a direction different from the extending direction of the pipe mounting portion. The sensor mounting portion to which the water temperature sensor is mounted is substantially parallel to the outer surface of the cylinder head that communicates with the outlet of the cylinder head and the outlet of the cylinder head is open, and the direction is different from the direction in which the pipe mounting portion and the sensor mounting portion extend. We adopted an assembly housing that extends to the cylinder and has a valve mounting portion to which the valve is mounted.

本発明によれば、内燃機関のシリンダヘッドから伸長する配管やリード線が車両のエンジンルームの内容積を圧迫する問題を回避することができる。 According to the present invention, it is possible to avoid the problem that the pipes and lead wires extending from the cylinder head of the internal combustion engine press the internal volume of the engine room of the vehicle.

本発明の一実施形態を、図面を参照して説明する。図１ないし図３に、本実施形態の組付用ハウジング１の構造を示している。本組付用ハウジング１は、内燃機関６のシリンダヘッド５に開設された冷却水の流出口５２に、冷却水を他の機器例えばヒータコアへと導く配管２、冷却水の温度を検出する水温センサ３、及び冷却水に混入した気体を冷却水から分離させるエア抜きバルブ４を組み付けるために使用される。 An embodiment of the present invention will be described with reference to the drawings. 1 to 3 show the structure of the assembly housing 1 of the present embodiment. The assembly housing 1 has a cooling water outlet 52 provided in the cylinder head 5 of the internal combustion engine 6, a pipe 2 that guides the cooling water to another device such as a heater core, and a water temperature sensor that detects the temperature of the cooling water. 3 and an air bleeding valve 4 that separates the gas mixed in the cooling water from the cooling water are assembled.

組付用ハウジング１は、内燃機関６のシリンダヘッド５の流出口５２に連結する連結部１１と、配管２を取り付ける配管取付部１２と、水温センサ３３を取り付けるセンサ取付部１３と、エア抜きバルブ４を取り付けるバルブ取付部１４とを包有している。連結部１１、配管取付部１２、センサ取付部１３、及びバルブ取付部１４は、それらの内部が相互に連通した管状体である。図３に示しているように、連結部１１は、内燃機関６のシリンダヘッド５における流出口５２が開口しているリア側の外面５１に接合する。 The assembly housing 1 includes a connecting portion 11 connected to the outlet 52 of the cylinder head 5 of the internal combustion engine 6, a pipe mounting portion 12 for mounting the pipe 2, a sensor mounting portion 13 for mounting the water temperature sensor 33, and an air bleeding valve. It includes a valve mounting portion 14 to which the 4 is mounted. The connecting portion 11, the pipe mounting portion 12, the sensor mounting portion 13, and the valve mounting portion 14 are tubular bodies in which the insides thereof communicate with each other. As shown in FIG. 3, the connecting portion 11 is joined to the outer surface 51 on the rear side where the outlet 52 of the cylinder head 5 of the internal combustion engine 6 is open.

配管取付部１２は、内燃機関６のシリンダヘッド５のリア側の外面５１と略平行に伸び出している。図４に示すように、内燃機関６を車両のエンジンルーム内にいわゆる横置きの形で配置したとき、シリンダヘッド５のリア側の外面５１は車両の左右方向を向く。そして、配管取付部１２は、車両の前後方向に沿って、図示例では車両の後方に向けて突出する。 The pipe mounting portion 12 extends substantially parallel to the outer surface 51 on the rear side of the cylinder head 5 of the internal combustion engine 6. As shown in FIG. 4, when the internal combustion engine 6 is arranged in the engine room of the vehicle in a so-called horizontal manner, the outer surface 51 on the rear side of the cylinder head 5 faces the left-right direction of the vehicle. Then, the pipe mounting portion 12 projects toward the rear of the vehicle in the illustrated example along the front-rear direction of the vehicle.

配管２は、その端部を配管取付部１２に外嵌する。即ち、配管取付部１２を、配管２の端部の内に嵌入する。その配管２は、車両の前後方向に沿って、図示例では車両の後方に伸長する。シリンダヘッド５の流出口５２から流出する冷却水は、連結部１１を介して組付用ハウジング１の内部に流入し、配管取付部１２を通じて組付用ハウジング１から配管２内に流入し、この配管２を流通してヒータコアに至る。 The end of the pipe 2 is fitted onto the pipe mounting portion 12. That is, the pipe mounting portion 12 is fitted into the end portion of the pipe 2. The pipe 2 extends to the rear of the vehicle in the illustrated example along the front-rear direction of the vehicle. The cooling water flowing out from the outlet 52 of the cylinder head 5 flows into the inside of the assembling housing 1 through the connecting portion 11 and flows into the pipe 2 from the assembling housing 1 through the pipe mounting portion 12. It circulates through the pipe 2 and reaches the heater core.

センサ取付部１３は、内燃機関６のシリンダヘッド５のリア側の外面５１と略平行に、かつ配管取付部１２が伸びる方向とは相反する方向に伸び出している。図４に示すように内燃機関６を車両のエンジンルーム内に配置したとき、センサ取付部１３は車両の前後方向に沿って、図示例では車両の前方に突出する。 The sensor mounting portion 13 extends substantially parallel to the outer surface 51 on the rear side of the cylinder head 5 of the internal combustion engine 6 and extends in a direction opposite to the extending direction of the pipe mounting portion 12. When the internal combustion engine 6 is arranged in the engine room of the vehicle as shown in FIG. 4, the sensor mounting portion 13 projects in the front-rear direction of the vehicle and in front of the vehicle in the illustrated example.

水温センサ３は、センサ取付部１３の内に嵌入する。水温センサ３は、リード線３１を介してＥＣＵ８に電気的に接続している。そのリード線３１は、車両の前後方向に沿って、図示例では車両の後方に伸長する。連結部１１から組付用ハウジング１の内部に流入した冷却水は、センサ取付部１３内で水温センサ３に接触する。水温センサ３は、その冷却水の温度に対応する信号を出力し、リード線３１を通じてＥＣＵ８に伝送する。 The water temperature sensor 3 fits inside the sensor mounting portion 13. The water temperature sensor 3 is electrically connected to the ECU 8 via a lead wire 31. The lead wire 31 extends to the rear of the vehicle in the illustrated example along the front-rear direction of the vehicle. The cooling water that has flowed into the assembly housing 1 from the connecting portion 11 comes into contact with the water temperature sensor 3 in the sensor mounting portion 13. The water temperature sensor 3 outputs a signal corresponding to the temperature of the cooling water and transmits the signal to the ECU 8 through the lead wire 31.

バルブ取付部１４もまた、内燃機関６のシリンダヘッド５のリア側の外面５１と略平行に、かつ配管取付部１２及びセンサ取付部１３が伸びる方向とは相異する方向に伸び出している。図４に示すように内燃機関６を車両のエンジンルーム内に配置したとき、センサ取付部１３は車両の上下方向に沿って、図示例では車両の上方に突出する。 The valve mounting portion 14 also extends substantially parallel to the outer surface 51 on the rear side of the cylinder head 5 of the internal combustion engine 6 and extends in a direction different from the extending direction of the pipe mounting portion 12 and the sensor mounting portion 13. When the internal combustion engine 6 is arranged in the engine room of the vehicle as shown in FIG. 4, the sensor mounting portion 13 projects along the vertical direction of the vehicle and upward of the vehicle in the illustrated example.

エア抜きバルブ４は、バルブ取付部１４の内に嵌入する。連結部１１から組付用ハウジング１の内部に流入した冷却水に混入している気体は、バルブ取付部１４を介してエア抜きバルブ４の内部空間に溜まる。冷却水から分離されたその気体は、エア抜きバルブ４を通じて組付用ハウジング１の外部に放出される。 The air bleeding valve 4 is fitted into the valve mounting portion 14. The gas mixed in the cooling water that has flowed into the interior of the assembly housing 1 from the connecting portion 11 collects in the internal space of the air bleeding valve 4 via the valve mounting portion 14. The gas separated from the cooling water is discharged to the outside of the assembly housing 1 through the air bleeding valve 4.

本実施形態の組付用ハウジング１を採用することにより、内燃機関６のシリンダヘッド５から伸長する配管２やリード線３１が、車両のエンジンルームの内容積を圧迫する問題を有効に回避できる。例えば、小型のハイブリッド車両において、図４に示しているように、内燃機関６とＰＣＵ７との間に確保するべきクリアランスＣをより狭めることが可能となり、これらを限られたエンジンルーム内に適切に収めることができる。従って、小型車両専用の小形の内燃機関６またはＰＣＵ７を新規に設計開発せず、既存の内燃機関６及びＰＣＵ７の設計を援用することが可能となる。 By adopting the assembling housing 1 of the present embodiment, it is possible to effectively avoid the problem that the pipe 2 and the lead wire 31 extending from the cylinder head 5 of the internal combustion engine 6 press the internal volume of the engine room of the vehicle. For example, in a small hybrid vehicle, as shown in FIG. 4, it is possible to further narrow the clearance C to be secured between the internal combustion engine 6 and the PCU 7, and these can be appropriately made in the limited engine room. Can fit. Therefore, it is possible to utilize the existing designs of the internal combustion engine 6 and the PCU 7 without newly designing and developing the small internal combustion engine 6 or the PCU 7 dedicated to the small vehicle.

また、内燃機関６の組立工程にて、予め組付用ハウジング１に配管２や水温センサ３、エア抜きバルブ４を取り付けておいてから、それらを包括したＡＳＳＹを内燃機関６のシリンダヘッド５に連結するという手順をとることも可能となる。さすれば、内燃機関６全体を組み立てるメインラインにおける工数の削減、作業性の一層の向上を見込める。 Further, in the assembly process of the internal combustion engine 6, the piping 2, the water temperature sensor 3, and the air bleeding valve 4 are attached to the assembly housing 1 in advance, and then the ASSY that includes them is attached to the cylinder head 5 of the internal combustion engine 6. It is also possible to take the procedure of connecting. By doing so, it is expected that the man-hours in the main line for assembling the entire internal combustion engine 6 will be reduced and the workability will be further improved.

因みに、図４に示した本実施形態では、シリンダヘッド５からラジエータに向かう冷却水の流出口はシリンダヘッドの側面、車両の前方を向く外面に開口しており、当該流出口から流出する冷却水をラジエータへと導く配管０は車両の前方に伸長する。 Incidentally, in the present embodiment shown in FIG. 4, the outlet of the cooling water from the cylinder head 5 to the radiator is open to the side surface of the cylinder head and the outer surface facing the front of the vehicle, and the cooling water flowing out from the outlet is open. The pipe 0 that leads to the radiator extends to the front of the vehicle.

なお、本発明は以上に詳述した実施形態に限られるものではない。例えば、上記実施形態の組付用ハウジング１の配管取付部１２に取り付ける配管２は、冷却水をヒータコアへと導くものであったが、冷却水をラジエータへと導く配管を、配管取付部１２に取り付ける態様をとることも可能である。つまり、配管を通じて冷却水を流入させる対象の機器は、ヒータコアに限定されない。 The present invention is not limited to the embodiments described in detail above. For example, the pipe 2 attached to the pipe attachment portion 12 of the assembly housing 1 of the above embodiment guides the cooling water to the heater core, but the pipe that guides the cooling water to the radiator is provided to the pipe attachment portion 12. It is also possible to take a mounting mode. That is, the target device for flowing the cooling water through the pipe is not limited to the heater core.

その他、各部の具体的な構成は、本発明の趣旨を逸脱しない範囲で種々変形が可能である。 In addition, the specific configuration of each part can be variously modified without departing from the spirit of the present invention.
