Why so many K230UB's in Singapore today?

are just like the citaros just that...
1. They are NOT full low floor.
2. Their air-con stronger.
3. They are more confortable to sit in.
4. You would not get dizziness.
5. It is sometimes faster.Why dont you just say its like a OC500LE, just that it vibrates more?

40% KUBS jerk.But do not listen to the person who opened this topic's word.He just talk alot crap and is a clone account.He also likes to steal photos.

To me, I really like the Scania K230UBs (especially the Euro 5s).

Even though the Euro Vs jerk more then the Euro IVs, but their speed, it is just like you on a space shuttle driving towards Andromeda Galaxy at 10x the speed of light, which is about 3.00x10^8 m/s. They sometimes fly at expressways. Citaros? Come on! They always meet traffic jam and cannot move one!
The KUBs still can chit chat and sometimes have a drag race some more. -

Scania can be tune to lessen the vibration.K series engine got engine balancing.Modern Vehicles with single,triple,5 cylinders mostly got engine balancing due to its odd number of cylinders

I'm sorry, but your information is wrong. Any engine with an ODD number of cylinders will be harmonically-imbalanced and this includes engines with two banks of uneven cylinders (i.e. V6, V10).

Scania K230UB
- Engine: Scania DC9 (230bhp, 1050nm, less is used because of EGR)
- Capacity: 8867cc
- Transmission: ZF 6HP502C
Mercedes-Benz O530 Citaro- Engine: Mercedes-Benz OM906hLA (286bhp, 1120nm, maximised because of AdBlue technology)
- Capacity: 6374cc
- Transmission: Voith DIWA D854.5 (SBST)
There's no question about this. The KUBs "enjoy" a jerky acceleration, due to low power imput and the transmission with it. OC500LE runs on 6HP592C but the smoothness is apparent. On any other bus, it's hard to think a KUB accelerating at that speed. Citaro at traffic jam blame what, the bus ah? And how can a KUB fly when it's limited to 60km/h? It can barely attain 5th gear, let alone 6th. KUBs drag race KUBs plainly cause they don't stand a chance against other buses.Btw KUBs can't chitchat, they're buses. Facts boy, I have never been pressed into my seat on KUB before, other buses it's possible

I'm sorry, the Scania DC9 is 5-cylinder (4 valves per cylinder), four stroke 9-litre.
"With five cylinders, Scania believes the operational benefits of the Scania modular combustion concept are used to the fullest. Five cylinders also allows for a shorter block and crankshaft. The engine features two specially designed balancer shafts at the crankshaft to counter the forces generated by the five cylinder firing sequence. This results in the engine runing more smoothly and promotes longer service life."
From a website, though I find the running smoothly part quite bullshit.

Sorry but I meant the BCs chit chatting. You don't see this often with citaros, uh?

The fact that the Scania DC9 engine uses EGR isn't the reason why they're so underpowered. It's the way that Scania have calibrated the engine in order to meet stringent Euro emissions norms.The difficulties that Scania faced during the transition from Euro 4 to Euro 5 are readily apparent. They had to redesign the 'bottom end' of their engine for Euro 5 with a larger bore diameter and therefore new pistons, with the result being an increase of swept volume from 8.9-litres to 9.3-litres. Additionally, a Variable Geometry Turbocharger (VGT) replaced the fixed geometry turbocharger found on older engines to improve low-end throttle response and to assist with the EGR system. Finally, an XPI system was used in lieu of the unit injectors on the older engines. Essentially, the DC9 for Euro 5 was a brand new engine.
In contrast, Mercedes-Benz have used the same engines since Euro 2 (OM 457 LA/hLA and OM 906 LA/hLA) with only minor upgrades (e.g. exhaust system for Euro 4, 5 and EEV to accommodate the BlueTec SCR system) but with no changes to the actual engine blocks themselves.
Stay tuned for Euro 6 engines!

But still, we need a experienced [ prefably still working in SBST ] to tell us :
WHY DID SBST BUY SCANIA K230UBs?
It is STILL a mystery... up till NOW.
1 theory is that Scania is already ordered by SBST before citaros was introduced.
Need confirmation :) -

Sweeeeeeeeet! Can't wait for Euro VI engines.
Maybe next year with ultratechnology can achieve Euro X already

Mercedes-Benz have already been developing bus and truck engines that are approximately four levels ahead of Euro 6 for the past few years. Technology available today combined with the right knowhow can meet future legislation.

See!! The new Citaros are Euro 6 soon and so advanced technology, so SBS and SMRT should buy 800 new Citaros 3 from the fund!!!!

So many manufacturers today turn to turbocharger cause of the stringent Euro 5 emission.In fact when Proton develop the light single turbo CFE engine without the stuff for euro 5 the dyno show 148ps@5200rpm and 228nm@1950rpm for a single turbo 1.6 engine but only achieve Euro 3,but when they install the stuff the power decrease to 140ps@5000rpm and 205nm@2000rpm

What's wrong with turbocharging??
Without turbocharging, you would sacrifice fuel economy, driveability and the ability to meet current and future emissions legislation. Practically all buses made from Euro 2-spec onwards have turbocharged engines, and twin-stage turbocharging (with one low pressure turbo and one high pressure turbo) or Variable Geometry Turbochargers becoming commonplace from Euro 5.

It is no longer a secret once SMB228X and his 'clonades' saw it.

Need confirmation :)You need to understand the fact that SBST can sometimes be a cheapskate pain in the ass. Buying the same model in large quantities not only standerdises the fleet to an extent (one thing on their minds that time), but also makes overall price of order cheaper. Therefore, cheap bus chassis and engine+cheap bodywork+mass order=huge savings for SBST. See how much savings they will aquire from this junk in the future
Not a mystery at all... And the Citaro (2nd generation) was introduced in 2005, original in 1997. You say what again? -
Scanias are good!!! Can take in more passengers than Citaros! Citaros have bad design at the rear, only one line of standing passenge is possible. Not possible to have two rows of standing passenger, as backside will be rubbing with backside or cock rubbing with the sitting passenger!!

Scanias tend to vibrate overtime, look at the N113s of history, the L113CRLs of SMRT and now the K230UBs.. The Scania K230UB had steps leading to the rear, inconvenient as people may lose their step. This design has been banned for public buses by LTA and only the arrangement of the MANs or the Citaros are allowed. "Citaros have bad design at the rear, only one line of standing passenge is possible." This is the only possible design possible with operaters now, unless they come out with another innovative design. And sure, Scania engines are long lasting, but use your bloody sense you want a massive rocking chair or a comfortable bus? The A22s and the Citaro have almost no vibrations when idle. Look at the K230UBs after just 5 years, the Euro Vs just 2 years..

Never been on a chionging Citaro but have experience chionging KUBs several times. They aren't slow actually, they can be real fast too. It all depends on the driver.
