Description
しかも、前記共通ハウジングの外周部分に、エンジン冷却水が供給される冷却水路が設けられるので、エンジン冷却水により共通ハウジングひいては圧力センサの冷却を図ることができ、シリンダ室内の圧力検出の安定性、信頼性を高めることができる。このとき、前記冷却水路を、共通ハウジングの外周壁部に、取付穴の内周壁との間に空隙を形成する凹部を設けると共に、その空隙の上下部に夫々位置してOリングを配置して形成することにより、簡単な構成で、冷却水路を形成することが可能となる。
図3は、例えば自動車のエンジンの1個のシリンダ室1の要部(上部)部分の構成を概略的に示している。シリンダ室1は、シリンダブロック2とシリンダヘッド3とから構成され、その内部には、ピストン4が上下動するように設けられている。シリンダ室1の上部には、図で右左に位置して吸気口及び排気口を夫々開閉するバルブ5及び6が設けられている。そして、シリンダヘッド3には、前記吸気口と排気口との中間部に位置して、本実施例に係るエンジンヘッドモジュール7(以下、単にモジュール7と称する)が設けられる。尚、このモジュール7は、エンジンの全気筒に搭載される。
Claims (5)
- エンジンのシリンダヘッドに設けられるものであって、
前記シリンダヘッドに形成された取付穴に嵌合取付けされる共通ハウジングに、インジェクタ、点火プラグ、シリンダ室の内圧検出用の圧力センサの三者を、それらの先端部が夫々前記シリンダ室内に臨むように一体的に組付けて構成されると共に、
前記共通ハウジングの外周部分には、エンジン冷却水が供給される冷却水路が設けられ、前記冷却水路は、該共通ハウジングの外周壁部に、前記取付穴の内周壁との間に空隙を形成する凹部を設けると共に、前記空隙の上下部に夫々位置してOリングを配置することにより形成されることを特徴とするエンジンヘッドモジュール。 - 前記インジェクタ及び点火プラグ並びに圧力センサは、夫々シリンダ室の中心を向くように、前記共通ハウジングに対して傾斜状に組付けられることを特徴とする請求項1記載のエンジンヘッドモジュール。
- 前記共通ハウジングの下端部の外周壁には、前記取付穴の内周壁との間に圧力を遮断するための耐熱性のガスケットが設けられると共に、前記共通ハウジングの上端部には、前記取付穴の上面を塞ぐように配置され、前記シリンダヘッドにボルト締めされる連結部が設けられていること特徴とする請求項1又は2記載のエンジンヘッドモジュール。
- 前記共通ハウジングの上面部には、前記インジェクタ及び点火プラグ並びに圧力センサと、外部との電気的接続のための共通化されたコネクタ部が設けられていることを特徴とする請求項1ないし3のいずれかに記載のエンジンヘッドモジュール。
- 前記共通ハウジングの下面、並びに、前記インジェクタ及び圧力センサの先端は、前記シリンダヘッドの下面と、凹凸なく滑らかに連なる面を形成するように構成されていることを特徴とする請求項1ないし4のいずれかに記載のエンジンヘッドモジュール。
