Description
図1は、実施の形態1に係るハイブリッド車両の構成を示す図である。図1に示すように、ハイブリッド車両1は、車輪14を回転駆動するための1つの動力装置として、エンジン2を備える。エンジン2は、ガソリン又は軽油などの炭化水素系の燃料の燃焼により動力を出力する内燃機関であって、吸気装置、排気装置、燃料噴射装置、点火装置、冷却装置などを備える。吸気装置を構成する吸気通路30には、吸入空気量を調整するためのスロットル弁32が設けられている。吸気通路30におけるスロットル弁32の上流にはモータ34aによって駆動される電動コンプレッサ34が設けられている。吸気通路30は、電動コンプレッサ34と並列に、電動コンプレッサ34をバイパスするバイパス通路40が設けられている。バイパス通路40には、バイパス通路40を流れる空気量を調整するためのバイパス弁42が設けられている。
次に、本発明の実施の形態2について説明する。図6は、実施の形態2に係るハイブリッド車両の要部の構成、空気の流れ、及び冷却水の流れを示す図である。本実施の形態に係るハイブリッド車両は、電動コンプレッサ34を通過した空気を冷却する冷却装置44を備える。冷却装置44は水冷のインタークーラである。冷却装置44は、電動コンプレッサ34とバイパス通路40との間を循環する空気の温度の上昇を抑える役割を有している。図6に示す例では、冷却装置44は、吸気通路30の電動コンプレッサ34より下流でバイパス通路40の分岐点よりも上流に設けられている。
上述の実施の形態では、電動コンプレッサ34を作動させて電力を消費する場合、圧力比が一定に維持されるように消費電力に応じてバイパス弁42の開度を調整しているが、少なくともバイパス弁42が開いてさえいればよい。つまり、バイパス弁42が開かれて、電動コンプレッサ34で送り出された空気が循環するようになっていればよい。
