SCR係一種專門針對NOx既技術，而歐四同歐五之間只係NOx既含量再調低
只要提升轉換效率，歐四直升歐五唔係冇可能，我唔明點解會關EGR事
Volvo既D9B一早就出晒歐四歐五同EEV既config，如果要用埋EGR，佢唔會咁快手 ...
就算係E3 車....都有EGR.....
Euro 4 用SCR 既車....其實Engine 本身已經有EGR 呢個功能...... |

-40%...
有d無喱頭
咁究竟-40%(亮警報)的時候, 要入廠or繼續營運?
如果亮警報就要回廠的話, 又何須-40%呢, 盞費時失事
如果唔入廠, 假設300匹就剩番170匹左右, 上斜仲慢過DM, 應該無司機願意咁樣踩落去, 一定port ...
呢套system早在歐四時已經用緊,如果個尿素缸無尿素,
架車就會自動cut power,直至入番尿素為止
不過呢d車日日都有人check住個尿素缸,同埋一缸尿素
平均2-3日先需要入,所以暫時未聽過因為無尿素而要
port車
另外話,睇報紙講架車下星期重回B1,試2-3個後又可能做
6C或104 |

如果九巴大量入尿素車,
要人人有人睇住個尿素缸,
批車營運成本分分鐘又高左,
但係Cutpower呢樣野如果可以DISABLE,
對巴士公司黎講會靈活D. |

一架半架當然可以專人照顧,當大量採用時,就自然好似
入油咁,日日入,或者係架車裝個尿素缸錶
Cut Power唔係唔可以取消,不過架車既然係sell環保,如果
無尿素都可以繼續行車,結果明明係歐四五只係得歐二三
標準,只係浪費成套系統 |

大部份Euro4用SCR 0既引擎，上到Euro5都要SCR+EGR，所以要換引擎
No it doesn't. The change to bring the engine to Euro 5/EEV standard has not much to do with the hardware of the engine actually. All that needs to be done is a better catalytic converter, and some software changes to the engine management system. The engine itself can (or should in this case) actually be retain without being physically changed.
That's how the likes of Evobus, Volvo have been doing anyway - a reason which confuse me - why AVD1 has to leave HK to do that upgrade? I thought volvo can take the parts and do the work in HK, since there are Euro 5 B9TLs in production anyway. |

That's why EGR-technology has their friends - a strong reason to drive KMB to order Scanias I believe.
The idea of SCR is you pay for the adBlue (or urea solution), but the expense will be compensated because SCR engines are actually more fuel efficient. It doesn't look like it is less good either - with all the Volvos, ADLs and Evobus in Europe (and of course those E500s with Citybus/NW) |

170匹 Lance都180匹la ATEU1遲早一定步GC629後塵
p.s:ATEU1歐4果陣係340匹
咁其實而家 ATEU1 換左 E5 之後有幾多匹馬力?
如果架車馬力冇變 - 340hp
340 x 0.6 = 204hp ~

我係巴士公司都入Scania 呀
唔洗入尿素播, 大呀呀 15~16 年車的, 入足咁多年尿素果o的都係錢...
不如入 Scania 好過 ADL 呀...
但坦白講, ADL 的車比 Scania 好坐... |

其實兩隻響得個市場度, 一定各自有佢既賣點!
如果我無錯既話, ADL本身車價較便宜, 而且零件配置方面ADL呢間用開既亦有優勢(esp對於新城)
不過如果當年城巴可以買多d 2800既話, 話唔定Scania而家已經響港島普及化左~
講返轉頭, 城記當年都幾勇!!
