Description

本発明は，排気ターボ過給機等の過給機を備えて成るいわゆるクロスフロー型の内燃機関において，そのシリンダヘッドに関するものである。   The present invention relates to a cylinder head in a so-called crossflow type internal combustion engine including a supercharger such as an exhaust turbocharger.

最近，クロスフロー型の内燃機関（内燃機関のシリンダヘッドにおいて，クランク軸線の方向にこれと平行に延びる左右両長手側面のうち一方の長手側面にシリンダへの吸気ポートを開口し，他方の長手側面にシリンダからの排気ポートを開口して成る内燃機関）において，これに排気ターボ過給機等の過給機を適用するに際しては，例えば，特許文献１，２に記載されているように，前記シリンダヘッドにおける一方の長手側面に吸気ポートに対する吸気マニホールドを接合する一方，他方の長手側面側の部分に，排気タービンとブロワー圧縮機とを直結して成る排気ターボ過給機を配設し，この排気ターボ過給機におけるブロワー圧縮機にて圧縮される過給吸気を，途中にインタークーラを備えた過給吸気管路を介して前記吸気マニホールドに導くという構成にしている。   Recently, a cross-flow type internal combustion engine (in the cylinder head of an internal combustion engine, an intake port to the cylinder is opened on one of the left and right long side surfaces extending in parallel to the crank axis direction, and the other long side surface is opened. In the case of applying a supercharger such as an exhaust turbocharger to an internal combustion engine in which an exhaust port from a cylinder is opened, the above-mentioned, for example, as described in Patent Documents 1 and 2, An intake manifold for the intake port is joined to one longitudinal side of the cylinder head, and an exhaust turbocharger is provided on the other longitudinal side to directly connect an exhaust turbine and a blower compressor. The supercharged intake air compressed by the blower compressor in the exhaust turbocharger is supplied to the intake manifold through a supercharged intake line having an intercooler. Is the configuration that leads to de.

この場合，従来においては，前記排気ターボ過給機におけるブロワー圧縮機から前記吸気マニホールドに至る過給吸気管路を，シリンダヘッドと別体にして，シリンダヘッドの上面又はクランク軸線方向の一端面の部分に，当該シリンダヘッドを横断するように配設する構成にしている。
特開２００７−１７０２２０号公報 特開２００７−２２４８５７号公報 In this case, conventionally, the supercharged intake pipe line from the blower compressor to the intake manifold in the exhaust turbocharger is separated from the cylinder head, and the upper surface of the cylinder head or one end surface in the crank axis direction is provided. The portion is arranged so as to cross the cylinder head.
JP 2007-170220 A JP 2007-224857 A

しかし，前記シリンダヘッドを横断する前記過給吸気管路を，シリンダヘッドと別体にして，シリンダヘッドの上面の部分に配設した場合には，内燃機関における全高さが，前記過給吸気管路における高さの分だけ高くなり，シリンダヘッドの一端面の部分に配設した場合には，内燃機関におけるクランク軸方向の全長が長くなり，いずれにおいても，内燃機関の大型化を招来するばかりか，シリンダヘッドの周辺における構成が複雑になるのであり，しかも，前記過給吸気管路が，シリンダヘッドと別体の構成であると，内燃機関の冷間始動等に際して，排気側における熱を吸気の予熱に利用することが困難であるという問題があった。   However, when the supercharged intake pipe crossing the cylinder head is provided separately from the cylinder head and disposed on the top surface of the cylinder head, the total height in the internal combustion engine is such that the supercharged intake pipe If it is increased by the height of the road and is disposed on one end face of the cylinder head, the overall length of the internal combustion engine in the crankshaft direction becomes longer, and in any case, only the size of the internal combustion engine is increased. In addition, the configuration around the cylinder head is complicated, and if the supercharged intake pipe is configured separately from the cylinder head, the heat on the exhaust side is reduced when the internal combustion engine is cold started. There was a problem that it was difficult to use for preheating of intake air.

また，従来においては，前記過給吸気管路の途中に，ブロワー圧縮機にて圧縮された吸気に対するインタークーラを設ける場合に，このインタークーラを内燃機関に対して強固に支持するためのブラケット機構が別個の部品として必要になるという問題もあった。   Further, conventionally, when an intercooler for intake air compressed by a blower compressor is provided in the middle of the supercharged intake pipe line, a bracket mechanism for firmly supporting the intercooler with respect to the internal combustion engine. There is also a problem that is required as a separate part.

本発明は，これらの問題を解消したシリンダヘッドを提供することを技術的課題とするものである。   An object of the present invention is to provide a cylinder head that solves these problems.

Since it can be heated with exhaust gas, in other words, intake air heating can be performed, the startability of the internal combustion engine from a cold state is particularly improved, and an intake air heating device such as an air heater or a glow plug is conventionally used. Without being provided, it can be reliably improved with a very simple configuration, and even when an intake air heating device is provided as in the prior art, a small capacity of the intake air heating device can be achieved.

この接合部２１には，図１，図３及び図４に示すように，前記排気ターボ過給機１４のブロワー圧縮機１３における吐出口からの過給吸気管路１６が，前記排気マニホールド１１の下側を通って前記過給通路１７に連通するように複数本のボルト２２の締結にて着脱可能に接合されている。   As shown in FIGS. 1, 3, and 4, a supercharged intake pipe 16 from a discharge port of the blower compressor 13 of the exhaust turbocharger 14 is connected to the joint 21. The plurality of bolts 22 are detachably joined so as to communicate with the supercharging passage 17 through the lower side.

この構成によると，シリンダヘッド４のうち他方の長手側面７の側の部位に配設した排気ターボ過給機１４のブロワー圧縮機１３から前記シリンダヘッド４のうち一方の長手側面６における吸気マニホールド９に至る過給吸気管路１６のうち前記シリンダヘッド４を横断する部分を，シリンダヘッド４の一部に形成した過給通路１７にて構成することができる。   According to this configuration, the intake manifold 9 on the one longitudinal side surface 6 of the cylinder head 4 from the blower compressor 13 of the exhaust turbocharger 14 disposed on the other longitudinal side surface 7 side of the cylinder head 4. A portion of the supercharged intake pipe line 16 that extends across the cylinder head 4 can be constituted by a supercharge passage 17 formed in a part of the cylinder head 4.

また，前記過給吸気管路１６の途中に設けられるインタークーラ１９は，これを前記シリンダヘッド４における一方の長手側面６に一体に設けた取付け部１８に接合したことにより，前記シリンダヘッド４にて直接に支持される。   Further, the intercooler 19 provided in the middle of the supercharged intake pipe 16 is joined to a mounting portion 18 provided integrally with one longitudinal side surface 6 of the cylinder head 4, so that the cylinder head 4 Directly supported.

前記シリンダヘッド４に一体に形成した前記過給通路１７は，図１，図４及び図５に示すように，平面視において，少なくともその一部，つまり，前記過給吸気管路１６からの入口部が，前記シリンダ２からの排気ポート１０に対して一枚の隔壁板２３を隔てて隣接している。   As shown in FIGS. 1, 4 and 5, the supercharging passage 17 formed integrally with the cylinder head 4 is at least a part in plan view, that is, an inlet from the supercharging intake pipe 16. The portion is adjacent to the exhaust port 10 from the cylinder 2 with a single partition plate 23 therebetween.

すなわち，前記シリンダヘッド４の内部には，図示のように冷却水ジャケット２４が設けられているが，前記一枚の隔壁板２３の部分には，前記冷却水ジャケット２４を設けない構成にして，この一枚の隔壁板２３にて前記排気ポート１０と過給通路１７とに区画するように構成している。   That is, a cooling water jacket 24 is provided inside the cylinder head 4 as shown in the figure, but the cooling water jacket 24 is not provided in the portion of the one partition plate 23, The single partition wall plate 23 is divided into the exhaust port 10 and the supercharging passage 17.

この構成により，前記排気ポート１０から前記過給通路１７への熱伝達が前記一枚の隔壁板２３を介して行われるから，内燃機関を冷めた状態から始動するときにおける排気ガスによる吸気加熱を的確に達成できる。   With this configuration, heat transfer from the exhaust port 10 to the supercharging passage 17 is performed through the single partition wall plate 23, so that intake air heating by the exhaust gas when the internal combustion engine is started from a cooled state is performed.

また，前記過給通路１７内のうち前記隔壁板２３の部分には，図３，図４及び図５に示すように，流れ方向に対して薄板状に構成した放熱用フィン２５が，前記隔壁板２３から前記過給通路１７内に一体に突出するように設けられており，この放熱用フィン２５によって，前記した排気ガスによる吸気加熱をより助長できる。   Further, in the portion of the partition wall plate 23 in the supercharging passage 17, as shown in FIGS. 3, 4 and 5, a heat radiation fin 25 configured in a thin plate shape in the flow direction is provided with the partition wall. It is provided so as to project integrally from the plate 23 into the supercharging passage 17, and the heat radiation fin 25 can further promote the intake air heating by the exhaust gas.

なお，前記過給通路１７のうち前記放熱用フィン２５を設ける入口部分は，その入口部分における通路断面積を部分的に大きくすることにより，前記放熱用フィン２５を設けることによる流れ抵抗の増大を回避するとともに，流れの入口抵抗を低減するように構成している。   In addition, the inlet portion of the supercharging passage 17 where the heat dissipating fins 25 are provided increases the flow resistance by providing the heat dissipating fins 25 by partially increasing the cross-sectional area of the inlet portion. In addition to avoiding this, it is configured to reduce the flow inlet resistance.

また，前記図示の実施の形態は，過給機として排気ターボ過給機を使用した場合であったが，本発明は，これに限らず，前記排気ターボ過給機に代えて，機械式過給機等のその他の構成の過給機を使用できることは勿論であり，更にまた，前記過給通路１７は，前記各シリンダ２間の部位に設けても良いことはいうまでもない。   In the illustrated embodiment, an exhaust turbocharger is used as a supercharger. However, the present invention is not limited to this, and instead of the exhaust turbocharger, a mechanical turbocharger is used. Needless to say, a turbocharger having another configuration such as a turbocharger can be used, and it is needless to say that the supercharging passage 17 may be provided at a position between the cylinders 2.
