次世代內燃機預備，HONDA HCCI新燃燒系統進行實測
| |
|

每次能源危機，HONDA總是會推出因應相關對策，如1970年代的CVCC稀薄燃燒，1980年代著重高性能與經濟性的的VTEC可變氣門，如今為了下一世代的內燃發動機，最新的HCCI同源增壓點火系統已進入實驗階段。
所謂HCCI（Homogenous-Charge Compression-Ignition），就是同源增壓點火燃燒技術，單就機械結構上來說，將空氣和燃油在活塞中巧妙地混合以達平衡狀態，並藉由活塞直接壓縮以點燃混合物，基本上與過程柴油引擎比較相似。這可是HONDA挑戰TOYOTA Hybrid的第二項科技，雖然HONDA也具備Hybrid技術，但依然難敵TOYOTA Prius的攻勢，造成HONDA Civic Hybrid銷售不彰，因此HONDA將替Civic Hybrid裝置HCCI系統，讓油耗表現能提升至每加侖65英哩，約每公升27.7公里左右，如此一來便有著更高的競爭力與Prius較量較量。
其實HONDA發展HCCI系統已有多年時間，且不少車廠早在1970年代便投入研發，但一直以來卻受到材質與科技無法突破，尤其在自燃時機仍難以克服，所以當HONDA開發這項技術後早在汽車領域廣為流傳，認為HONDA即將成功。據可靠消息指出，這種新技術離正式量產可能還需1-2年時間，但HONDA有可能在2008年先行展示Prototype，本體當然是直列四缸引擎，猜測最有可能亮相時間為2008年的日內瓦車展，正式量產化則在2008/9年左右。
然而這種HCCI系統要價成本可不便宜，倘若加裝在現行車款中，少說要多上美金3-4000元左右，也就是新台幣9.6-12萬元不等，然而若能降低燃油約40-50﹪，這樣的價差不用一年就可回本，其實對車主來說是一大利多，當然現在就等這項新技術問世量產，接下來受惠的仍是市場大眾。
