【発明の詳細な説明】 ディーゼル機関用の燃焼室をもつシリンダヘッド本発明は、燃料を直接噴射され るディーゼル機関用の燃焼室をもつシリンダヘッドに関する。[Detailed description of the invention] Cylinder head with combustion chamber for diesel engine This invention is a cylinder head with a combustion chamber for a diesel engine. This invention relates to a cylinder head with a combustion chamber for a diesel engine.
ディーゼル噴射機関において燃料を高い液圧で燃料ポンプから直接シリンダへ噴 射し、そこで圧縮と緩続の膨張を伴う燃料の燃焼とを行なうことは公知である。In diesel injection engines, fuel is injected directly from the fuel pump into the cylinder at high hydraulic pressure. It is known to carry out compression and combustion of fuel with slow expansion.
燃料弁は一部開き一部閉じかつニードルにより燃焼室空間に対して閉じ、られる ノズルと ゛して構成されて、再滴下を防止する。The fuel valve is partially open, partially closed, and closed to the combustion chamber space by the needle. It is configured as a nozzle to prevent re-dropping.
多孔ノズルの代りに、旋回挿入片をもつ単一ノズルがしばしば使用されて、燃料 に旋回運動を与え、それにより霧化を助長する。Instead of a multi-hole nozzle, a single nozzle with a swirl insert is often used to gives a swirling motion to the surface, thereby promoting atomization.
予燃焼室付き機関では、燃料はシリンダの本来の燃焼室へ噴射されるのではなく 、長く狭い通路または通路系により燃焼室とつながっている小さい予燃焼室へま ず噴射される。In engines with pre-combustion chambers, the fuel is not injected into the cylinder's natural combustion chamber; , a small pre-combustion chamber baffle connected to the combustion chamber by a long narrow passage or passage system. It is sprayed immediately.
燃料が直接ピストン向合噴射されそこで燃料の燃焼が行なわ スれる今まで公知 のディーゼル噴射機関の欠点は、とりわけ、ピストン冷却のため噴霧油を使用せ ねばならない゛にもかかわらず、ピストンの高い温度が認められることである。Until now, the fuel is injected directly opposite the piston and the fuel is combusted. The disadvantages of diesel injection engines include, among other things, the use of atomized oil for piston cooling. Despite this, high piston temperatures are observed.
ピストンの熱負荷や外部への熱放射も比較的大きい。この熱放射を吸収するため それに応じた量の空気または水を使用せねばならない。The heat load on the piston and the heat radiation to the outside are also relatively large. to absorb this thermal radiation A corresponding amount of air or water must be used.
この系の別の欠点は、さらにピストン重量がそれに応じて大きくなることに認め られ、これは大きい振動質量を意味する。Another disadvantage of this system is that the piston weight is also correspondingly large. , which means a large vibrating mass.
さて本発明は、上述した欠点を大幅に除去する、燃料を直接噴射されるディーゼ ル機関用の燃焼室をもつシリンダヘッドを目的としている。The present invention now provides a direct fuel injection diesel engine which largely eliminates the above-mentioned drawbacks. It is intended for cylinder heads with combustion chambers for engine engines.
本発明のいっそうよい理解のために、図面により本発明を説明する。For a better understanding of the invention, the invention will be explained with reference to the drawings.
第１図は１：１の尺度で示されたシリンダヘッドの上からの平面図を示し、 第２図は第１図、のＡ−Ａ線によるシリンダヘッドの縦断面を示し、 第３図は第１図によるシリンダヘッドの下からの平面図を示し、 第４図は第３図のＢ−Ｂ線によるシリンダヘッドの部分縦断面を示している。FIG. 1 shows a plan view from above of the cylinder head shown on a 1:1 scale; FIG. 2 shows a longitudinal section of the cylinder head taken along line A-A in FIG. FIG. 3 shows a plan view from below of the cylinder head according to FIG. 1, FIG. 4 shows a partial longitudinal section of the cylinder head taken along line B--B in FIG.
第１図ないし第４図によるシリンダヘッド１はこれに適した材料から作られてい る。The cylinder head 1 according to FIGS. 1 to 4 is made of a material suitable for this purpose. Ru.
シリンダヘッドｌはここには図示してないシリンダヘッドボルトを収容する穴２ ．２’、２”および２″′をもっている。これらのボルトはシリンダヘッドｌの 固定に役だつ。弁棒を収容するために穴３．３′が役たつ。ボルト頭部空間は４ ．４’、４″および４″で示されている。The cylinder head l has a hole 2 that accommodates a cylinder head bolt (not shown here). ．． 2', 2'' and 2''. These bolts are located in the cylinder head l. Useful for fixation. Hole 3.3' serves to accommodate the valve stem. Bolt head space is 4 ．． 4', 4'' and 4''.
弁全開５は吸気弁９の収容に役だち、弁全開】３は排気弁１４の収容に役たつ。The fully open valve 5 serves to accommodate the intake valve 9, and the fully open valve 3 serves to accommodate the exhaust valve 14.
２つの穴６および６′は弁案内に役だつ。揺動レバーブロックの支持面は７で、 またシリンダヘット座は８で示されている。Two holes 6 and 6' serve for valve guidance. The support surface of the swing lever block is 7, Further, the cylinder head seat is indicated by 8.
ピストンの下降により、吸気開口＋２を経て空気が吸入される。これに続いて、 吸入された空気はピストンヘッドとシリンダヘッド１との間で圧縮される。噴射 弁ＩＩを介して燃料が燃焼室１０へ噴射され、点火過程が始まる。続いて膨張行 程が行なわれる。燃焼した燃料と空気との混合気の吹出しは排気弁１４を介して 行なわれる。Due to the lowering of the piston, air is sucked in through the intake opening +2. Following this, The intake air is compressed between the piston head and the cylinder head 1. injection Fuel is injected into the combustion chamber 10 via valve II and the ignition process begins. followed by an expansion line The process will take place. The mixture of burned fuel and air is blown out through the exhaust valve 14. It is done.
直接＠１１←煉るディーゼル機関用の燃焼室をつシリンダヘッドでは、ピストン の重量は小さく、それにより振動質量もわずかしか存在しないことがわかった。Direct @11← In cylinder heads with combustion chambers for diesel engines, the piston It was found that the weight of is small and therefore there is only a small amount of vibrating mass.
高温の混合排気により、改善されるかまたは強められた予熱空気が吸気空間の予 熱のために生じ、これは燃料−空気混合気の点火の改善を意味する。シリンダか らの熱放射は大きく減少せしめられ、したがって放熱はシリンダへラド１へ集中 する。したがってピストンの油冷却系は不要になり、これは燃料の燃焼がピスト ン内で行なわれる系に対して著しい進歩とみなされる。The hot mixed exhaust air provides improved or enhanced preheating air to the intake space. Due to heat, this means improved ignition of the fuel-air mixture. Is it a cylinder? The heat radiation from the cylinders is greatly reduced, and therefore the heat radiation is concentrated to the cylinder Rad1. do. Therefore, there is no need for an oil cooling system for the piston, which means that the combustion of fuel is This is considered a significant advance over systems that are carried out in-house.
