Description
【０００１】[0001]
【発明の属する技術分野】この発明は４バルブエンジン
の吸気ポートの片側を直角方向から持ってきたシリンダ
ーヘッドの構造でである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a cylinder head in which one side of an intake port of a four-valve engine is taken at right angles.
【０００２】[0002]
【従来の技術】従来は４バルブエンジンの吸気ポートの
片側を止め低回転時に渦流を発生させるものである、対
称位置に吸気ポートがある物も考えられている。2. Description of the Related Art Conventionally, there has been considered an intake port of a four-valve engine in which one side is stopped and a vortex is generated at a low rotation speed.
【０００３】[0003]
【発明が解決しようとする課題】吸気ポートを２分割し
ても向きは緩いハの字で低回転の片側吸気の時しか渦流
は強くならなかった。Even if the intake port is divided into two parts, the vortex flow becomes stronger only at the time of low-speed one-side intake with a loose C-shape.
【０００４】[0004]
【課題を解決するための手段】吸気ポートを２分割して
片側を直角方向から導く、４気筒の場合、Ｔ型の吸気ポ
ートが２個出来る、このポートを４個のストレート吸気
ポートより小さくしてバルブの中心からストレートポー
ト側にずらす、Means for Solving the Problems In the case of a four-cylinder in which the intake port is divided into two and one side is guided from a right angle direction, two T-shaped intake ports are formed. This port is made smaller than the four straight intake ports. Off the center of the valve to the straight port side.
【０００５】[0005]
【発明の実施の形態】Ｔ型側に燃料噴射弁を付けると２
個でよく、ポートのストレート側から空気を入れ、渦流
を保ちながら、その内側に混合気の渦流を生成する、渦
流方向はバルブからのポートの位置である程度決まる、
これで混合気が中央に集まりやすくして点火し、周りの
空気で燃焼を促進させる。DESCRIPTION OF THE PREFERRED EMBODIMENTS When a fuel injection valve is attached to the T-type side,
It can be an individual, inject air from the straight side of the port, create a vortex of the mixture inside it while keeping the vortex, the direction of the vortex is determined to some extent by the position of the port from the valve,
This makes it easier for the air-fuel mixture to collect in the center and ignites, and the surrounding air promotes combustion.
【０００６】[0006]
【発明の効果】したがって常時渦流を生成し、周りが空
気のため燃焼効率が上がり、さらに燃費が良くなる。As a result, a vortex is always generated, and the surroundings are air, so that the combustion efficiency is increased and the fuel efficiency is further improved.
