Description

【0001】
燃焼室を中央にして一つのシリンダにピストンを対面させて配置して、向かい合わせ、クランク・シャフトの歯車で同時に同じサイクルをおこなわせた逆水平対向で、2サイクルのレシプロ・ディーゼル機関を発明した。ピストン・ヘッドが対面するため、バルブの取り付けは、不可能でクリアランス部の上部方向に縦向きの燃料噴射ノズルが取り付けられる。
燃焼室が1つで2つのピストンを動かしている。一般の燃焼室と同じ圧縮比の場合、排気量は、2倍になる。この機関は、2気筒が一対である。
【0002】
一つの燃焼室を中央にして両側にシリンダ・ブロックを設け、2つのピストンが挿入され2つのピストンは、同時に動き同じサイクルがおこなわれる。ガソリンを燃料とした2サイクル・レシプロ・ガソリン機関が同様に発明できた。
点火プラグは、筒型の燃焼室の上面の中央に取り付けられる。 燃焼室容積は、単純的に計算した場合、2倍となる。
【0003】
この2サイクル・エンジンは、向かい合った2つのピストンが同時に、歯車によって回転してツインで動き、1行程目に掃気と圧縮を行ない、2行程目に燃焼と排気を行なう。シリンダ・ヘッドは、凹型ヘッドとして中央燃焼の希薄省燃費型の向かい合い・同時燃焼・2サイクル・レシプロ・ディーゼル・機関が発明された。同じく胴内燃料噴射型の凹型シリンダ・ヘッドを採用して中央燃焼の希薄省燃費型の向かい合い・同時燃焼・2サイクル・レシプロ・ガソリン機関の2タイプの開発に成功した。
向かい合い・同時燃焼・2サイクル・レシプロ・ディーゼル機関の圧縮比は、22:1〜25:1位の圧縮比として、燃焼室へ高圧霧化噴射の微粒子化ノズルの採用で、ノッキングの発生を防ぎ、高速回転を可能にさせている。
向かい合い・同時燃焼・2サイクル・レシプロ・ガソリン機関の,圧縮比は、7:1〜10:1位の圧縮比として、燃焼室の高温化を少し押さえてノッキングを防止して、高速回転を可能にさせている。

動力機械の動力となる。船舶の機関、車の機関、建設機械の機関、農業機械の機関、航空機の機関、発電機の機関、等に用いられる小型、軽量、高速、低燃費低公害の部品数の少ない作り安い廉価な、新開発のレシプロ機関である。
【従来の技術】
1気筒当たり330CC以下の排気量のレシプロ・ディーゼル機関の開発、実用化が出来ない。
【発明が解決しようとする課題】
本発明において、ディーゼル向かい合い機関として、660CCとさせた場合は、1気筒当たり165CCのダブル・ツィンの4気筒の実用化の可能性が高いと推測される。
【課題を解決するための手段】
向かい合いで同時燃焼をさせることによって、1気筒当たり165CCに小型化したレシプロ・ディーゼル機関の実用化が可能となった。
165CCの気筒を二つ向き合わせ燃焼室を共有してシリンダを1体化させてツィンにした2つのピストンは、双方のクランク・シャフトを歯車で繋いで同じ行程を同時に行なわせて、作動させ回転させて小排気量のレシプロ・ディーゼル機関の実用化を可能にした。
そして向かい合い・同時燃焼のレシプロ・ガソリン機関においては、低燃費、低公害の2サイクル機関としての実用化が達成されると思われる。
【発明を解決するための手段】
燃焼室を中央にしてピストン・ヘッドを向かい合わせたツィン・ピストンにより、小さな小排気量の多気筒化がはかられている。
【実施例】
向かい合わせたツィン・ピストン2気筒を2基備えて、1気筒あたり、165CCとした660CCの軽自動車用の2サイクル・レシプロ・ディーゼル機関と2サイクル・レシプロ・ガソリン・機関を開発する。
このエンジンの2サイクル・レシプロ・ディーゼル機関(図1)の圧縮比は22:1〜25:1の圧縮比とさせた。

燃焼室(4)は、中央に噴射ノズル(11)を1基〜2基が取り付けられる。シリンダ(6)は1つの筒の両側に設けられ左右にクランク・シャフト(3)が備えられツィン・ピストン(1)が2基、4気筒が作動される。
掃気システムは、過吸掃気方式、あるいは、クランク室掃気(8)方式のどちらかを選んで採用。
ツィン・ピストン(1)は、左右の出力軸(10)をかさ歯車(9)とシャフトで繋ぎ2つのピストンは、同時燃焼が行なわれる。
ツィン・ピストン(1)は、180度の回転作動差にセットされて対角で回転する。噴射ノズル(11)は、円筒燃焼室(5)の中央の上部に1基〜2基、多孔ノズルの噴射ノズル(11)が取り付けられてツィン・ピストン(1)に対して、同時噴射されて燃焼行程は、同時、一緒に行なわれる。
660CCの、向かい合い・同時燃焼・ダブル・ツイン・ピストン・2サイクルレシプロ・ガソリン機関(図1)は、胴内噴射ノズル(11)と、点火プラグ(11)が燃焼室中央の上部の扱いやすい角度の位置に取り付けられる。
圧縮比は、7:1〜10:1とする。
構造は、軽量とされる。あとは、ディーゼルの場合と基本的には同型である。この構造の機関において、色々の排気量のディーゼル機関とガソリン機関が、新しく考察できる。
【発明の効果】
660CCのディーゼル機関の実用化を可能にする。

[Prior art]
A reciprocating diesel engine with a displacement of 330 CC or less per cylinder cannot be developed or put into practical use.
[Problems to be solved by the invention]
In the present invention, when 660 CC is used as a diesel-facing engine, it is presumed that there is a high possibility that a double twin 4-cylinder with 165 CC per cylinder will be put into practical use.
[Means for Solving the Problems]
Simultaneous head-to-head combustion enabled the commercialization of a reciprocating diesel engine downsized to 165 CC per cylinder.
The two pistons, with two cylinders of 165CC facing each other and sharing a combustion chamber, forming a single cylinder and twinning, operate the same stroke simultaneously by connecting both crankshafts with gears to operate and rotate. This enabled the commercialization of a small displacement reciprocating diesel engine.
It is expected that a face-to-face, simultaneous combustion reciprocating gasoline engine will be practically used as a two-cycle engine with low fuel consumption and low pollution.
