Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はディーゼル機関の給気装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to an air supply system for a diesel engine.
本発明は従来技術がなく、全く新しい給気装置である。 The present invention has no prior art and is a completely new air supply device.
本発明はディーゼル機関の性能向上、特に燃焼の改善を
目的に、燃焼にあずかる空気を如何に効果的にシリンダ
内に送りこむかという課題に対して成されたものであり
、技術的課題を要約すると以下の通シである。即ち、（
１）給気を層状に供給する装置、（２〕酸素ガスの活性
を生かす装置、（３）異常燃焼防止に窒素ガスの活用、
（４）燃費改善、（５）排出ガスのＮＯｘ低減である。The present invention was made in response to the problem of how to effectively send air that participates in combustion into the cylinder for the purpose of improving the performance of diesel engines, particularly improving combustion.To summarize the technical problem, The following is the general policy. That is, (
1) A device that supplies supply air in layers, (2) A device that utilizes the activity of oxygen gas, (3) Utilization of nitrogen gas to prevent abnormal combustion,
(4) improved fuel efficiency, and (5) reduced NOx in exhaust gas.
本発明のアイデアとして新しい点は以下の通りである。 The new ideas of the present invention are as follows.
（１）給気を３層に分けて各別に供給すること。(1) Divide the air supply into three layers and supply each layer separately.
即ちｇｅｍ酸素ガス、ｂ、窒素ガス、Ｃ１酸素と窒素と
の混合ガスとし。That is, gem is oxygen gas, b is nitrogen gas, and C is a mixed gas of oxygen and nitrogen.
（２）３層の集合点は同軸配置としたことであり。(2) The gathering points of the three layers are arranged coaxially.
その特徴とするところは、給気通路の吸入弁の上流側に
酸素ガス及び窒素ガスを各別に導入する酸素導入路及び
窒素導入路を設け、上記酸素ガス及び窒素ガスの発生器
を設けたことである。Its features include the provision of an oxygen introduction passage and a nitrogen introduction passage for introducing oxygen gas and nitrogen gas separately on the upstream side of the intake valve in the air supply passage, and a generator for the oxygen gas and nitrogen gas. It is.
この場合は１層状に３種類のガス体がシリンダ内に供給
されるので、酸素ガスの強情性、窒素ガスの異常燃焼抑
止効果及び混合ガスの中間層が個個に作用して燃焼の最
大効果を引き出す。In this case, three types of gas bodies are supplied into the cylinder in one layer, so the obstinacy of oxygen gas, the abnormal combustion suppressing effect of nitrogen gas, and the middle layer of mixed gas act individually to maximize the combustion effect. bring out.
以下図面を参照して本発明による実施例につき説明する
。Embodiments of the present invention will be described below with reference to the drawings.
第１図は本発明による１実施例の給気装置の系統を示す
説明図、第２図は同給気装置を拡大して示す断面図であ
る。FIG. 1 is an explanatory diagram showing a system of an air supply device according to an embodiment of the present invention, and FIG. 2 is an enlarged sectional view of the same air supply device.

側に配設されている。In the figure, a diesel engine body 1 is centered around an air supply pipe 2.
Exhaust pipe 3. An exhaust turbo supercharger 4 and a gas generator 5 are arranged. At the inlet of the air supply pipe, the air is separated into three layers toward the suction valve 1a: an oxygen gas introduction pipe 2a, a nitrogen gas introduction pipe 2b, and a mixed gas or air introduction pipe 2c. Exhaust valve 1b is exhaust pipe 3
It is placed on the side.
上記構成の場合の作用について述べる。The operation in the case of the above configuration will be described.
層状に３種類のガス体がシリンダ内に圧送されると、燃
焼に最も関与する酸素ガスが強情性ガスとして作用する
一方で、窒素ガスは前記酸素ガスによる異常燃焼を抑制
する作用を行い、混合ガスは両ガスの中間の作用を用い
全体として燃焼を効果的に促進させる。When three types of gas bodies are pumped into the cylinder in a layered manner, oxygen gas, which is most involved in combustion, acts as an obsessive gas, while nitrogen gas acts to suppress abnormal combustion caused by the oxygen gas, and the mixture The gas effectively promotes combustion as a whole using an action intermediate between the two gases.
上述の場合は次の効果がある。 The above case has the following effects.
（１）給気管入口部に３層に導入管を分別する。(1) Separate the inlet pipe into three layers at the inlet of the air supply pipe.
（２）酸素ガスの強い活性を生かすと共に異常燃焼防止
に窒素ガスを活用する。(2) Take advantage of the strong activity of oxygen gas and utilize nitrogen gas to prevent abnormal combustion.
（３）燃費改善効果が大である。(3) Great effect on improving fuel efficiency.
（４）排出ガスのＮＯｘ低減効果が犬である。(4) Dogs are effective in reducing NOx in exhaust gas.
