上記判定部１０aがガス配管内で冷媒が凝縮していると判定すると、制御部１０bは、電動弁ＥＶＡ,ＥＶＢ,ＥＶＣ,ＥＶＤの開度を所定開度よりも開く配管凝縮時制御を行う。 - 特許庁

A control device grasps an air-fuel ratio to determine whether or not premixed compression self-ignition combustion operation can be executed on the basis of a map indicating relationship between EVC and an air-fuel ratio at which stable premixed compression self-ignition combustion can be achieved.例文帳に追加

制御装置は、空燃比を把握し、安定な予混合圧縮自着火燃焼が可能な空燃比とＥＶＣとの関係を示すマップに基づいて予混合圧縮自着火燃焼運転が可能な領域であるか否かを判断する。 - 特許庁

Both the valve close timing EVC of the exhaust valve 8 and the valve open timing IVO of the intake valve 6 are controlled in the vicinity of the top dead center of a piston when the engine is in a high load, and a spark plug 9 performs ignition and flame propagation combustion.例文帳に追加

The combustion control device for the internal combustion engine capable of changing over combustion between spark ignition combustion and compression self ignition combustion by internal EGR gas includes a control means 11 controlling internal EGR gas remaining quantity by adjusting exhaust valve close timing EVC and controlling total gas quantity by adjusting intake valve close timing IVC when combustion is changed over from the compression self ignition combustion to the spark ignition combustion.例文帳に追加

火花点火燃焼と内部ＥＧＲガスによる圧縮自己着火燃焼とを切り換え可能な内燃機関の燃焼制御装置において、前記圧縮自己着火燃焼から前記火花点火燃焼へ切り換える場合に、排気弁の閉時期ＥＶＣを調整することにより前記内部ＥＧＲガスの残量を制御し、吸気弁の閉時期ＩＶＣを調整することにより総ガス量を制御する制御手段１１を備える。 - 特許庁

An internal EGR amount calculation part 60 calculates a clearance volume EGR amount on the basis of exhaust valve closing timing EVC, a valve overlap amount OL, a blowback EGR amount on the basis of an engine rotation speed Ne and an intake pipe pressure Pm, and an internal EGR amount Gegr by adding the clearance volume EGR amount and the blowback EGR amount.例文帳に追加

また、内部ＥＧＲ量算出部６０は、排気バルブ閉時期ＥＶＣに基づいて隙間容積ＥＧＲ量を算出すると共に、バルブオーバーラップ量ＯＬ、エンジン回転数Ｎｅ及び吸気管圧力Ｐｍに基づいて吹き戻しＥＧＲ量を算出し、更に隙間容積ＥＧＲ量と吹き戻しＥＧＲ量との加算により内部ＥＧＲ量Ｇｅｇｒを算出する。 - 特許庁
