Description
例えば、特定の吸気ポートに導入される燃料と空気との混合比が高くなると(燃料が濃くなると)ノッキングが生じ易くなる。一方、特定の吸気ポートに水分が多く導入されると失火し易くなる。このため、このような構成とすれば、差圧タンクに吸い出した液媒を、各吸気ポートに分配して排出することができるので、特定の吸気ポートに燃料が濃くなったり、水分が多くなったりすることを防止できる。したがって、ノッキングや失火の発生を抑制できる。
図1は、吸気装置100を備えるエンジンEが示される。このようなエンジンEは、吸気のタイミングと吸気時間とが吸気制御装置Aにより制御される。また、本実施形態に係るエンジンEは、排気経路と吸気経路との間に排ガスの一部を吸気経路に再循環するEGR(Exhaust Gas Recirculation:排ガス再循環)装置Bを備えている。
図2は、本発明に係るインテークマニホールド2を模式的に示した斜視図である。インテークマニホールド2は吸気装置100を構成し、上述のように、下流側がシリンダヘッド1の側面に連結固定される。一方、上流側には供給管5及び還流通路4がフンランジ部19で連結固定される。
次に、差圧タンク13による液媒の吸い出しについて図3を用いて説明する。図3(a)には、差圧タンク13内に液媒がない状態が示される。このような状態において、エンジンEの吸気バルブが開弁されているとする。係る場合、導入部10は負圧となると共に、差圧弁23が開弁状態となる。これにより、第1室24と第2室25とが同圧となり、液溜部12から液媒が第1室24に吸い出されることはない。
上記実施形態では、エンジンEは、EGR装置Bを備えているとして説明した。しかしながら、本発明の適用範囲はこれに限定されるものではない。EGR装置Bを備えていないエンジンEのインテークマニホールド2に本発明を適用することは当然に可能である。
