Description
前記燃料タンクから前記高圧ポンプまでのラインに熱交換可能なパージタンクを備え、
前記高圧ポンプからの高温の燃料を前記パージタンクに戻すよう前記パージタンクに接続される第一のパージラインを備えると共に、前記コモンレールからの高温の燃料を前記パージタンクに戻すよう前記コモンレールから延在して前記パージタンクに接続される第二のパージラインを備え、
前記パージタンクでは、高温の燃料を気化させることにより高温の燃料の蒸発潜熱によって前記高圧ポンプへの燃料を冷却するよう構成したことを特徴とする液化ガスエンジンの燃料供給装置、に係るものである。
[表1]
DME 軽油
蒸発潜熱 kJ/kg 467.13 300
沸点(@1at) ℃ −25 180〜360
比熱Cp kJ/kg・K 2.99 1.7
液密度 g/cc 0.67 0.83
になり、1kgのDMEを気化させた場合には、蒸発潜熱/比熱=467.13/2.99=156から1kgのDMEは約156℃の温度低下の熱量になり、熱量が全て燃料の温度変化に使用されるとして、全体の20%を気化させた際には、液体燃料80%を約40℃低下させる。
