Evaluation of Explosion-proof Intake Oxygen Sensor with Protection Tube by Numerical Simulation
数値シミュレーションによる吸気酸素センサ用プロテクタの防爆性評価
By installing the oxygen sensor on the engine air intake side, an advanced EGR control becomes possible and fuel efficiency improvement can be expected. On the other hand, if the fuel vapor reaches the sensor element of zirconia-based solid electrolyte, the fuel vapor can ignite because the element is heated. The risk, however, is slight. Therefore, the authors evaluated the explosion-proofness of the protection tube by numerical simulation method they developed, and it was confirmed that the dimension between the inner and outer protection tubes has a great contribution.酸素センサをエンジン吸気側に設置することで，高度なEGR 制御が可能となり，燃費向上が期待される．一方，気化燃料が高温となるジルコニア型センサ素子に触れ，発火するリスクも僅かながら存在するため，本報では，素子を覆うプロテクタの防爆性の調査結果及び，シミュレーションによるメカニズム究明について紹介する．
