Summary:PROBLEM TO BE SOLVED: To provide an injector in a form in which the injector can be exactly and easily attached, in a cylinder head in which two suction ports are arranged while responding to one cylinder, and the injectors are attached to both the suction ports.SOLUTION: A plurality of paired injector attachment holes 40 are formed at one side face of a cylinder head 2 in parallel with one another. An injector unit 43 is attached in a state that a plurality of paired injectors 36 are branched to a delivery pipe 42. A cover attachment rib 55 for fixing a head cover with a bolt is formed at an upper part of an intermediate part of the paired injector attachment holes 40 in a vertically-long state. When attaching the injector unit 43, since each injector 36 can be inserted into the injector attachment hole 40 with the cover attachment rib 55 as a mark, the insertion of the injector 36 can be exactly and easily performed. 【課題】1つの気筒に対応して2つの吸気ポートを設け、両吸気ポートにそれぞれインジェクタが取り付けられるシリンダヘッドにおいて、インジェクタを正確かつ簡単に取付けできる形態で提供する。【解決手段】シリンダヘッド2の一側面には、複数対のインジェクタ取付け穴40が並列して形成されている。インジェクタユニット43は、デリバリ管42に複数対のインジェクタ36を分岐した状態で取付けた構成になっている。一対のインジェクタ取付け穴40の中間部の上方には、ヘッドカバーをボルトで固定するためのカバー取付け用リブ55が上下に長い姿勢で形成されている。インジェクタユニット43を取り付けるに際しては、カバー取付け用リブ55を目印として各インジェクタ36をインジェクタ取付け穴40に挿入できるため、インジェクタ36の挿入を正確にかつ簡単に行える。【選択図】図9
