Description
図1は、本発明の各実施の形態にかかる内燃機関の制御装置及びその周辺の構造を説明するための図である。図1に示すように、内燃機関10には吸気通路12および排気通路14が連通している。吸気通路12は、上流側の端部にエアフィルタ16を備えている。エアフィルタ16を収納するエアフィルタボックスには、吸気温THA(すなわち外気温)を検出する吸気温センサ18が組みつけられている。また、排気通路14には排気浄化触媒32が配置されている。
次に、本発明の実施の形態2について説明する。図1に示すように内燃機関10に筒内圧センサ44を設けた場合、各行程における筒内圧P(θ)をモニタすることができる。実施の形態2では、筒内圧センサ44により筒内圧P(θ)をモニタし、筒内圧P(θ)に応じて排気弁48の開弁タイミングを定める。実施の形態2の基本的な構成は実施の形態1と同様であるが、実施の形態2は、ノッキングコントロールシステムを備えていない内燃機関10に適用することも可能であるため、図1のノッキングセンサ41は備えていなくても良い。
41 ノッキングセンサ
44 筒内圧センサ
48 排気バルブ
Claims (1)
- 筒内圧を検出する筒内圧検出手段と、
燃焼または膨張行程中に、前記筒内圧と所定のしきい値とを比較する比較手段と、
前記筒内圧が前記所定のしきい値以下である場合に、電磁駆動式の排気弁を開弁する排気弁制御手段と、を備え、
前記筒内圧が前記所定のしきい値以下となったタイミングが、最大トルクを発生させる所定のクランク角よりも進角側であるときは、前記タイミングで排気弁を開弁することなく、前記最大トルクを発生させる所定のクランク角で排気弁を開弁することを特徴とする内燃機関の制御装置。
