2T比起4T引擎
在先天的條件上因為2T引擎必須在同一個曲軸行程內完成兩個動作
因此燃燒的效率較差,熱效率也比4T引擎低下
這是事實,不是2T狂熱份子可以否認的
但是如果這樣就要給2T引擎貼上一個不環保的標籤,那也是說不過去的
事實上,環保這兩個字本身就是很有爭議性的主題
大多人只看到表面,卻看不到全貌
用紙袋比較環保還是用塑膠袋?
可能大部份人會認為當然是紙袋環保,然後事實上呢?
塑膠袋使用石化材料製作,使用後經過焚化處理的產物是CO2跟H2O
而製作紙袋的材料是植物,在製作過程中也會產生比製造塑膠更多的污染
且大部份的紙製品是無法 or 難以回收的
就算回收,回收過程中處理這些廢紙所花費的成本跟造成的污染,有沒有人想過?
人往往只會看到他想看的那一面
2T引擎結構簡單,這表示製造2T引擎過程中所花費的成本較低
使用較少的資源與能量就能製造出性能比4T更好的引擎
結構簡單也表示引擎本體可以縮小化、輕量化。
對於車身、車架的設計也更有彈性。 同性能輸出的2T引擎跟4T引擎
2T引擎很容易可以設計的比4T引擎更輕巧,相對的車身也更輕巧
節省的資源不僅是引擎本體,整台車都可以更節省資源。
輕巧的車身可以減少輪胎與煞車的消耗
油耗表現也得以提升 (不過會被2T本身燃燒效率不佳的問題稀釋掉)
2T引擎簡單易保養,花在保養、維修上的成本得以大幅降低
縱使2T引擎先天的確比起4T引擎在排污上居於劣勢
但是整體上來說,從整個製造、生產、銷售、保養來看,是否真的比4T引擎"不環保"??
然而排污上雖然居於劣勢
但是這可以靠技術來突破
老梗就是光陽的X-mode這台2T車,狠狠甩了官員一巴掌
這告訴我們,技術上是有能力製作出夠環保的2T車的
那如果再綜合2T引擎先天的優勢,你敢給2T扣上不環保這個帽子嗎?
官員的腦殘不是一天兩天的事
要打著環保的口號,就要抓些可憐的倒楣鬼來當墊背
這叫樹立共同敵人,凝聚群眾團結
表面上看起來不環保的2T車就成了代罪羔羊
殊不知如果好好的改善2T車的排污,是可以得到又環保、又輕巧,製造過程更節省的引擎
且附帶了保養方便、油耗表現優異、性能較同級4T車更佳的好車
偏偏2T引擎就成了環保議題下的犧牲品。
表面上不說,私底下的打壓有人看不出來嗎?
政府就在大力宣導4行程才是環保的,你廠商硬要給我推一台更環保的2T車
這是要給政府難堪嘛
當年2T/4T之爭如此,現今的化油/噴射也是如此
你成為政府操弄意識形態的無知群眾,還洋洋得意嗎?
