[問題] 關於機車環保還是汽車環保議題 (有影片)
各位好
小弟昨天看了一段影片,
是流言終結者測試機車與汽車誰比較環保,影片如下:
http://www.youtube.com/watch?v=kClPM7TibPo
結論是
雖然機車在油耗與二氧化碳排放量都優於汽車
但在CO/HC/NOx這三項上面排放量卻是汽車的好幾倍
(等不及可以看14分00左右的初步結果)
小弟不懂的是,機車汽車都是內燃機,
在目前201X年的科技下,環保(排氣部分)數據卻差這麼多,
到底是甚麼部分造就了這些差異呢?
還請教各位了!!

不好意思 此篇是僅討論定距離與時速的排放廢氣部分
如果還要加入塞車/乘載人數等其他變因實在太難討論XD
已修改內文與標題!!
