B7Tl同B9TL

cn兄好耐無見
小弟覺得B7TL又唔係特別差,某程度上好似好過香港d B10TL,
最少起步都唔會慢,可能因為B7TL唔洗負擔埋冷氣機部份...?!
衰就衰在B7TL打冷震情況好嚴重 ,
而B10TL就唔覺有打冷震(少量震動當然一定有),
不過B7TL的表現真係一批批(倫敦為例),唔知係唔係後期少少的一批VOLVO改善過來,
當然保養方面都會影響左....

hey wright兄.好耐冇見
自番左英國忙得滯都唔記得add番你msn

入番正題.其實我都認為點解英國本土巴士馬力會比香港版本低.
係因英國車唔洗拖冷氣同埋...英國車有幾可超載得好似香港咁過份 (大陸印度另計)
諗下珍寶條傳動軸點解成日柴,但英國本土又冇乜問題就知.
所以呢,每度地方營運方式唔可硬生生則入去另一個地方.每度國程都唔同.
英國以前一副垃圾利蘭引擎達達聲咁行咁多年都冇問題,
香港呢邊,利蘭引擎全部捱唔住.亞拉伯年代已經狂換吉拿engine來代就知.
香港的運作條件對車來講真係harsh好多.

但其實當英國附近的國家全部都用 B12BLE 或者將來的 B13BLE 行雙層時，我覺得用 B7TL 或 B9TL 呢啲咁細馬力的引擎確實唔夠行喎。
單層用 B7 上斜都已經死死下咁，而家堆 B9TL 同 B10TL 都成堆廢車咁，正一阻塞交通；如果仲用 ...

Ok, name me a 英國附近的國家 which operates a single B12BLE then. No? Surprise. Volvo never sold one anywhere in Europe, let along a double decker version. Don't tell me Australia have shedloads of those things - Last time I check on the map it is the other side of the world of the UK, not quite 英國附近的國家 then.

Your obsession - yes, there is no other word to put it - of sticking a unnecessarily massive engine on a citybus is even worse than the power-obsessive kids that we regularly observe here. I don't know what the road is like in Australia - maybe you only have Porsches, Ferraris and Lambos on the road to warrant a bus like that just to pull out at bus stops - but in HK you have buses limited to 70-80kph, get stuck in traffic for much of their life, so a big engine is simply a waste. I travel to HK sparsely these days, but even I can tell what the traffic is like on a cross harbour service. A 12L engine just to get a bus out of the tunnel? You are having a laugh.

Oh, and I haven't mentioned the hideously long rear overhang of the B12BLE as well, which 1. limits the low floor area and 2. make it difficult to fit onto roads in HK and Europe.

The reality tells the story - Smaller turbocharged diesel engines are the way forward to deliver a better balance of power and fuel economy. That applies to all major bus manufacturer these day, including Volvo on the B7/B9 range, Scania on the Omnicity/Omnilink range, MAN on its Lion City range and Mercedes on the Citaro range. If you think B7/B9 have a small engine, you shall have a look at MAN, which has a 6.9L engine, and the Citaro, as standard option, makes do with a tiny 6.4L engine. Just talking about Volvo, the magnitude of which the B7RLE outsells the B12BLE, despite the so-called "advantages" you keep trying to sell, speaks for itself.

ATE24 has made some excellent points. In fact, back in those days when the 3BLs and 3Ns had "only" 220bhp, and still claw out the XHT, fully (over)loaded in most cases, day in day out. Why, all of a sudden, we need something with twice the power, costs twice as much on fuel possibly, and not much quicker, to do the same job? I'd rather the operators go with something that uses less fuel, because it means our fares are lower.

I hate to get personal, but this thread had been a rather constructive thread until you turn up. As far as I have observed, you always pop up, post a shedload of crap, and go back into your hideout to watch the drama unfold, instead of making any effort to defend what you said. I have a strong suspicion that you are just a trouble maker rather than a person talking with any kind of sense. And, back to your beloved B12BLE. I am more than willing to bet that Volvo is morely likely to put out a B9RLE as an replacement than a B13RLE. If that happens, I will be the first one to laugh.

The Leyland engine just can't cope with the hot and humid environment in SE Asia. In fairness, that was not what it was designed to do at the outset.

wrightap: The rattling of B7TL depends on a lot of factor - Engine, gearbox and bodywork combination. From my observation, in general B7TLs with a Voith gearbox are bad, but those with a President bodywork are worst. Those with a ZF box tends to fare better, but latter marks (the Mk.4 i.e. those with the new dashboard) seems to rattle badly. Oddly, ZF-equipped B7TL/Presidents are actually rather stable.

As DH12E engine is gonna fade out, I think B13BLE will finally come out...to suit that kind of irrational power-monster...

While D5E and D7E are facing a re-design or replacement (as mentioned in a few earlier issue of BUSES), D9B from Renault may be a good choice to power the heavy duty single decker in UK.

朋友, 依家咩年代呀? 細引擎容積o既 engine
已經大行其道, 而且絕對拍得住甚至好過裝
有大容積 engine o既車, 你諗o下, 如果要慳
油, 又要令個引擎室冇咁大, 又可以陀冷氣,
又可以低轉高扭, 好似 B9TL 咁已經唔錯啦!

B7TL 同 B7RLE 我未坐過, 不過我坐過同系
o既 B7R, 整體上我唔覺得佢有唔妥o既地方.

Don't be so sure, with Volvo now offering the B9R now, all bets are one, and I think a B9RLE is more likely than a B13RLE (think the B12B replacement will be called B13R, not B13B. Hence the low entry version should also be B13RLE as well).
