Abstract
Description
以下、図面を参照して、本発明を自動車用エンジンの吸気装置に適用した第1実施形態について詳細に説明する。以下の説明では、自動車の前進方向を前方とする(図1の座標軸を参照)。
図1に示すように、4気筒エンジン10(以下、単にエンジンという)は、クランク軸が左右方向に延在するように、自動車のエンジンルームに横置きに配置されるものである。エンジン10は、図示しないシリンダブロックと、シリンダブロックの上部に締結されるシリンダヘッド11と、シリンダヘッド11の上部に締結されるヘッドカバー12とを備えている。シリンダブロックには、それぞれ上下方向に延在するともに、左右方向に列設された4つの気筒(シリンダ)が形成されている。すなわち、各気筒は、略上下方向に延在するシリンダ軸線を有し、左右方向に延在するシリンダ列を形成している。各気筒には、コンロッドを介してクランク軸に連結されたピストンが摺動自在に収容されている。
図1に示すように、シリンダヘッド11の前側面13には、空気を各吸気ポート14に導入するための吸気装置20が設けられている。吸気装置20は、吸気マニホールド21および吸気プレート22、スロットルバルブ23(図2参照)、いずれも図示しないエアフィルタ、エアインレットを備えている。吸気マニホールド21は、吸気プレート22を介してシリンダヘッド11の前側面13に締結される。
以上のように構成した吸気装置20では、各分岐管27~30がシリンダヘッド11の前側面13から前方へと突出するとともに上方かつ後方へと湾曲し、吸気チャンバ26がヘッドカバー12に近接して配置されている。そして、吸気導入管25が、各分岐管27~30および吸気チャンバ26と、シリンダヘッド11およびヘッドカバー12との間に形成されるデッドスペースに配置されている。このように、吸気導入管25をデッドスペースに配置したため、吸気導入管25を延長してもデッドスペース内が満たされるだけであり、吸気装置20の外径寸法を比較的コンパクトにすることができ、エンジン10全体のサイズに与える影響を小さくすることができる。
第2実施形態に係る吸気装置100は、第1実施形態の吸気装置20と比較して吸気マニホールド101がブローバイガス導入通路120を有する点が大きく異なる。また、吸気マニホールド101の分割構造が、吸気マニホールド21の分割構造と比較して異なる。以下の説明では、吸気装置100について、吸気装置20と同様の構成については、同一の符号を付し、説明を省略する。
