Description
【０００１】[0001]
この考案は直噴式ディーゼルエンジンのシリンダー上部に空気室を設けた内燃 機関である。 This invention is an internal combustion engine in which an air chamber is provided above the cylinder of a direct injection diesel engine.
【０００２】[0002]
従来のディーゼルエンジンは燃料噴射による自然着火システムを用いるため、 無負荷運転状態では完全燃料する為排気ガスは清浄だが、高負荷運転状態におい てはシリンダー内の細部にまで酸素と燃料が反応せず未燃焼ガスが黒煙の状態で 排出されていた。 Conventional diesel engines use a self-ignition system that uses fuel injection.Thus, exhaust gas is clean because it is completely fueled under no-load operation, but oxygen and fuel do not react to the details in the cylinder during high-load operation. Unburned gas was emitted as black smoke.
【０００３】[0003]
本案はシリンダー内での未燃焼ガスに空気室より空気を送り出し、未燃焼ガス と酸化反応を起こし排気ガスを清浄化するものである。 In this case, air is sent from the air chamber to the unburned gas in the cylinder, and an oxidation reaction occurs with the unburned gas to purify the exhaust gas.
【０００４】[0004]
いまその解決手段を図面を追いながら説明すれば、 （イ）図−１のような構造にし、シリンダー９上部に空気室８を設ける。 （ロ）空気室８には、空気室用ピストン７を設ける。 （ハ）空気室用ピストン７にはピストンリング４及びバネ５を設ける。 （ニ）図−２から図−３のようにシリンダー内の圧力により空気室用ピストン７ が移動する構造とする。 Now, the solution will be described with reference to the drawings. (A) The structure shown in FIG. (B) The air chamber 8 is provided with an air chamber piston 7. (C) The piston 7 for the air chamber is provided with the piston ring 4 and the spring 5. (D) The air chamber piston 7 is moved by the pressure in the cylinder as shown in FIGS.

本案は、以上のような構造であるから次に作用を述べる． ４サイクルピストンエンジンの工程は給気・圧縮・爆発・排気の４工程から成 立っている． （イ）給気工程により給気口２より給気用開閉弁１が開きピストン１１が上死点 から下死点へ移動し空気３がシリンダー内へ入る。 （ロ）ピストン１１が下死点へ来た時点で給気用開閉弁１が閉じる。 （ハ）圧縮工程により、ピストン１１が下死点から上死点へ移動する。 （ニ）ピストン１１が上死点の時点において空気室８は空気の圧力により図−３ のような状態となる。 （ホ）燃料噴射ノズル１５より燃料が噴射され着火・爆発すると同時にピストン １１は下死点へ移動する。 （ヘ）ピストン１１が移動し空気室８の圧力の均衡が崩れ図−２の状態となり空 気室８の空気がシリンダー９へ入る。 （ト）ピストン１１が下死点で排気用開閉弁１４が開き燃焼ガスが排出される Since this model has the above structure, its operation will be described below. The process of a four-cycle piston engine consists of four processes: air supply, compression, explosion, and exhaust. (A) In the air supply step, the air supply opening / closing valve 1 is opened from the air supply port 2, the piston 11 moves from the top dead center to the bottom dead center, and the air 3 enters the cylinder. (B) When the piston 11 reaches the bottom dead center, the air supply on-off valve 1 is closed. (C) The piston 11 moves from the bottom dead center to the top dead center in the compression step. (D) When the piston 11 reaches the top dead center, the air chamber 8 is brought into a state as shown in FIG. (E) At the same time that fuel is injected from the fuel injection nozzle 15 to ignite and explode, the piston 11 moves to the bottom dead center. (F) The piston 11 moves, and the pressure in the air chamber 8 is unbalanced, as shown in FIG. 2, and the air in the air chamber 8 enters the cylinder 9. (G) When the piston 11 is at the bottom dead center, the exhaust on-off valve 14 opens and the combustion gas is discharged.

このことにより燃焼直後のシリンダー内に酸素を含んだ空気が入るため未燃焼 ガスは高温のまま酸化反応を起こし完全燃焼し排気ガスは清浄化する。 As a result, air containing oxygen enters the cylinder immediately after combustion, and the unburned gas undergoes an oxidation reaction at a high temperature, complete combustion, and the exhaust gas is cleaned.
