Description
図1は本発明の一実施形態にかかる内燃機関及びその制御装置の構成を示す図である。内燃機関(以下単に「エンジン」という)1は、吸気管2を有し、吸気管2の途中にはスロットル弁3が配されている。スロットル弁3には、スロットル弁3の開度THを検出するスロットル弁開度センサ4が設けられており、その検出信号が電子制御ユニット(以下「ECU」という)5に供給される。スロットル弁3には、スロットル弁3を駆動するアクチュエータ11が接続されており、アクチュエータ11は、ECU5によりその作動が制御される。
THCMD=THCB−THTR+THFB (1)
ここで、THCBは、作動気筒数(一部気筒運転中か、全筒運転中か)に応じて設定される基本スロットル弁開度であり、THTRは一部気筒運転から全筒運転への切換直後に有効となる過渡補正項であり、THFBは検出されるエンジン回転数NEがアイドル運転時の目標回転数NEOBJと一致するように設定されるフィードバック制御項である。
THTR=THTR−DTH0 (2)
一部気筒運転から全筒運転へ移行した時点から所定時間TTR0が経過すると、ステップS16の答が肯定(YES)となるので、ステップS18に進み、過渡補正項THTRを「0」に設定する。その後前記ステップS19に進む。
IGLOG=IGMAP+IGFB+IGCR (3)
2 吸気管
3 スロットル弁(吸気制御弁)
5 電子制御ユニット(運転制御手段、空気量制御手段、切換手段、補正手段、点火時期制御手段)
11 アクチュエータ(空気量制御手段)
12 点火プラグ
