- the closing timing of the valve timing control mechanism of the exhaust valve is advanced to confine unburned hydrocarbons (unburned HC) remaining in the combustion gas in the combustion chamber.
- the overlap period opened simultaneously with the intake valve is increased by retarding the valve opening / closing timing control mechanism of the exhaust valve.
- the exhaust gas once discharged into the exhaust passage is again sucked into the combustion chamber, and the unburned HC gas contained in the exhaust gas is again contributed to combustion, thereby reducing emissions.
- a valve opening / closing timing control mechanism (in the literature, a valve timing variable mechanism) that sets the opening / closing timing of an intake valve and an exhaust valve includes a mover made of a magnetic material, a valve opening coil, and a valve closing valve. It is comprised electromagnetically with a coil.
- Patent Document 2 there is a technique disclosed in Patent Document 2 relating to a control device for an internal combustion engine.
- an internal rotor is provided at the tip of the camshaft, and an external rotor to which rotational power is transmitted from the crankshaft is externally mounted on the internal rotor.
- the fluid pressure chamber between these rotors is divided into an advance angle chamber and a retard angle chamber by vanes, and by supplying fluid to one of the advance angle chamber and the retard angle chamber, the crankshaft and cam The relative rotation phase with the shaft can be freely changed.
- Patent Document 2 in order to regulate the relative rotational phase between the inner rotor and the outer rotor, the first lock pin urged by the spring and the first regulating groove into which the first lock pin is inserted are urged by the spring.
- the relative rotation phase between the internal rotor and the external rotor is set to a phase suitable for starting the internal combustion engine in a state where the first lock pin is fitted in the first restriction groove and the second lock pin is fitted in the second restriction groove. It is configured so that it can be held.
- JP 2003-120348 A paragraph number [0055] etc.
- valve opening / closing timing control mechanism described in Patent Document 2 has room for improvement rather than suppressing the amount of unburned HC discharged when the internal combustion engine is started.

And when the internal combustion engine is stopped, the control unit controls the phase control valve so that the internal combustion engine is moved to a locked state in which the relative rotational phase is held at the second lock phase. It may be stopped.
- the relative rotational phase between the driving side rotating body and the driven side rotating body is locked to the second lock phase. Then, the internal combustion engine is stopped.

- the lock state of the lock mechanism can be controlled by the lock control valve.
- valve opening / closing timing control mechanism including the driving side rotating body, the driven side rotating body, and the locking mechanism may be provided on the exhaust side.

Can be set.

- the relative rotational phase can be displaced in the advance direction by the urging force.
- the relative rotation phase is displaced in the advance direction to facilitate the shift to the locked state. If the first lock phase is in the center of the region where the relative rotational phase can be displaced, the combustion can be performed satisfactorily and the emission can be improved even if the internal combustion engine is started after the shift to the locked state. Connected. Further, if the relative rotation phase is on the advance side with respect to the lock phase at the start of the internal combustion engine, the relative rotation phase is further displaced in the advance direction, leading to an improvement in startability of the internal combustion engine.
- the relative rotational phase is displaced in the advance direction in the region from the retard side to the first lock phase under the driving condition in which the driving force due to fluid pressure is not generated.
- the biasing mechanism may apply a biasing force to the relative rotation phase.
- the lock mechanism when the lock mechanism is in an unlocked state when the internal combustion engine is started and the relative rotational phase is in a region on the retard side from the first lock phase, the internal combustion engine is moved relative to the camshaft at the start. Even if a torque for displacing the rotation phase in the retarding direction is applied, the relative rotation phase can be displaced to the first lock phase by the urging force of the urging mechanism, and the locked state can be entered. Then, by continuing the start-up of the internal combustion engine in the state of shifting to the first lock phase, a stable start can be realized by suppressing fluctuations in the relative rotation phase.
- the present invention includes a lock member in which the lock mechanism is supported so as to be shiftable with respect to one of the driving side rotating body and the driven side rotating body, and the other of the driving side rotating body and the driven side rotating body.
- a locking recess that is formed in the locking member and is detachable, and a biasing member that applies a biasing force to the locking member so that the locking member engages with the locking recess.
- the depth of the restriction recess that is connected to the lock recess and restricts the displacement of the relative rotational phase in the retard direction by engaging the lock member may be shallower than the depth of the lock recess.
- the relative rotation phase when the relative rotation phase is on the retard side with respect to the first lock phase, when the lock mechanism is shifted to the locked state in the first lock phase, the relative rotation phase is displaced in the advance direction.
- the lock member engages with the restriction recess.
- the relative rotational phase In this engaged state, for example, even in a situation where the relative rotational phase fluctuates due to torque acting from the camshaft, the relative rotational phase does not change significantly in the retarding direction with respect to the first lock phase, and the first lock It easily shifts to the locked state by engaging the lock recess with the phase. Further, since the lock recess is deeper than the restriction recess, the locked state is stably maintained.

Abstract
Description
その結果、冷熱状態にある内燃機関を始動する場合に未燃HCの排出を抑制し得る内燃機関の制御装置が構成された。
つまり、環境温度が設定値以上である場合には、設定値未満である場合と比較して未燃HCの排出量が少なく、吸気弁が開放を開始するタイミングで排気弁の開放状態を継続させる必要はない。この理由から、第2ロック位相にロックすることで、排気弁が閉塞した後に吸気弁の開放を開始するようにタイミングを設定し、適正な燃焼を行わせて内燃機関の始動を行えるのである。
〔基本構成〕
図1及び図2に示すように、内燃機関としてのエンジンEの吸気弁Vaの開閉時期を設定する吸気側の弁開閉時期制御機構Aと、排気弁Vbの開閉時期を設定する排気側の弁開閉時期制御機構Bと、エンジンEとを制御するエンジン制御ユニット(ECU)50とを備えて内燃機関の制御装置が構成されている。
図2~図4に示すように、排気側の弁開閉時期制御機構Bは、クランクシャフト1と同期回転する駆動側回転体としての外部ロータ20と、排気カムシャフト8に対して連結ボルト33により連結する従動側回転体としての内部ロータ30とを備えている。これらは排気カムシャフト8の回転軸芯Xと同軸芯上に配置され、外部ロータ20に対して内部ロータ30が内包される形態で回転軸芯Xを中心にして相対回転自在に支持されている。
弁ユニットVUは、ユニットケースに対して位相制御弁41とロック制御弁42とを収容した構造を有しており、このユニットケースに一体的に形成した流路形成軸部43を内部ロータ30の内周面30Sに挿入する形態で備えられている。この流路形成軸部43の外周面には、位相制御弁41のポートと連通する溝状部と、ロック制御弁42のポートと連通する溝状部とが形成され、これらの溝状部を分離するように流路形成軸部43の外周と、内部ロータ30の内周面30Sとの間には複数のリング状のシール44が備えられている。
エンジン制御ユニット50は、図1に示すように、マイクロプロセッサやDSP等を用い、ソフトウエアにより制御を実現するものであり、始動制御部51と、位相制御部52と、停止制御部53とはソフトウエアで構成されている。尚、これらはハードウエアで構成されるものでも良く、ソフトウエアとハードウエアとの組み合わせにより構成されるものであっても良い。
本実施形態のエンジンEは、燃焼室にインジェクタ9から燃料を噴射する形態で供給するため、冷熱状態で始動する際には、燃焼室を構成するシリンダ内壁に燃料の一部が付着する。そして、シリンダ内壁が低温である場合には、付着した燃料は殆ど気化せず、点火による燃焼の後にもシリンダ内壁に残留し、燃焼ガスと共に未燃HC(未燃焼の炭化水素)として排出されることになる。
ハイブリッド型車両あるいはアイドルストップ型の車両に対して本発明の内燃機関の制御装置を適用した場合には、次のように制御形態を設定しても良い。つまり、ハイブリッド型車両では、バッテリーの充電のためにエンジンEが自動的に始動し、充電が完了した後にはエンジンEを自動的に停止する。また、アイドルストップ型の車両では、ブレーキペダルが踏み込み操作された場合に、エンジンEが停止し、ブレーキペダルの踏み込みが解除された場合にエンジンEを自動的に始動する。
始動スイッチ55の人為的なON操作によりエンジンEを始動させる場合には、始動制御部51が、スタータモータ15を駆動してクランキングを行い、インジェクタ9から燃焼室に燃料を供給し、点火プラグ10での点火を実行する(#201、#202ステップ)。
