Description
図1は第一実施形態におけるエンジンの動弁装置11A,11B及びその周辺を示した断面図である。図1に示すように、当該エンジンは、ダブル・オーバーヘッド・カムシャフト式(DOHC式)のエンジンである。当該エンジンのシリンダヘッド12には、燃焼室14に連なる吸気ポート12A及び排気ポート12Bが設けられている。シリンダヘッド12の上方には吸気側の駆動カム軸13と排気側の駆動カム軸15とが配置され、その上方にはシリンダヘッドカバー16が被せられている。駆動カム軸13,15は、当該エンジンのクランク軸(図示せず)にチェーン等の回転伝達機構(図示せず)を介して接続されており、クランク軸(図示せず)に連動して回転する。シリンダヘッド12には、燃焼室14を吸気ポート12Aに対して開放/閉塞させる吸気バルブ機構17Aと、燃焼室14を排気ポート12Bに対して開放/閉塞させる排気バルブ機構17Bとが設けられている。吸気バルブ機構17Aは吸気側の動弁装置11Aにより開閉動作し、排気バルブ機構17Bは排気側の動弁装置11Bにより開閉動作する。動弁装置11A,11Bは、可変バルブタイミング式である。吸気側と排気側とでバルブ機構17A,17B及び動弁装置11A,11Bは略同一構造であるため、以下は吸気側について代表して説明する。
(1)窒化鋼からなる駆動カムを成形する工程。
(2)成形された駆動カムの表面のうち少なくとも摺動面に軟窒化処理を施すことで硬化層及び化合物層を形成する工程。
(3)前記化合物層を前記摺動面から除去し、前記硬化層を前記摺動面の最表面に露出させる工程。
図4は第二実施形態におけるエンジンの動弁装置の要部を取り出して示した断面図である。この実施形態は、第一実施形態から揺動カム機構32を除外したものであり、駆動カム13aはタペット31に直接接触している。
