Has the Citaro come out?

Do you see anybody posting Citaro on which service?? Better yet, do you see anyone posted whether Citaro on which depot already??

Just asking...

yes... there are almost 30 000 of them running on the roads around the world...

it has come out of C&C and it is now at an undisclosed location in Singapore. You may try Tuas South Ave 14. -

Geenreally blue tec refers to the technology used by Mercedes benz to cut Nox gases emmissions used in the EURO rating.
But the word is abused by bus fans to mean the actual fuel additive added.
So another definitionBlueTec
> A fuel additive added to the MB engine cupled with SCR to achieve EURO 3 or above. Bluetec essentially component includes urea (er....). the nitrogen moluecules (ions?) in urea react with emmission ages to remove posionous gaes.
the BlueTec kisok is built right next to the normal disel fueling kisok so that both fuel and fuel additive cna be filled up at same time. Bluetec additive fuels up using 10 percent the normal disel fuel time so its not really a hassle to fuel a MB EURO 3 or above bus.

Just to add, NOx leads to the formation of tropospheric ozone which is really undesirable. Both are irritants.
Leads to photochemical smog you see in major cities like Los Angeles. And it peaks in the bright sun because the chemical processes require sunlight.
In other words we won't want NOx as much as possible in S'pore.
Edit: Oh by the way, reducing NOx is a double-edged sword, because if you do so, you get a higher dose of ozone in your area because of the complex mechanism involved between both species.
So its not as simple as lower emissions = less pollution!

Fuel addictive? Rather an exhaust treatment addictive.
Adblue is injected after the turbocharger section of the exhaust 'journey', thereafter everything enters the SCR catalytic converter chamber, before releasing out. This chamber is fitted instead of a muffler.
Mercedes Benz calls this technology Bluetec. Just like MAN has their PM-KAT for their EGR system, Scania just calls it EGR for the same technology.
Nissan Diesel uses FLENDS (Final Low Emission New Diesel System) for their SCR technology, and is also applied in parallel with EGR on their Spacerunner RA series city bus (JDM) with MD92 series engines.
Nissan Diesel is the first company in the world to incorporate common rail diesel injection with an EGR system and a SCR one to produce buses with the lowest emissions on the market, coupled with fuel efficiency European buses can only envy at. Mitsubishi Fuso and Hino Motors prefer pure EGR on their systems, achieving the same level of emissions and fuel efficiency.
The chemical workflow of Adblue and exhaust goes like this:
CO(NH2)2+H2O (=AdBlue) --> 2NH3+CO2 --> 4NO+4NH3+O2 --> 4N2+6H2O
-
How much adblue does an average OC use? From what I know cars only need refill theirs every year but that is based on a mileage of 10000 km a year.
-
Roughly a liter per 100 kilometers. One Adblue tank holds about 30 plus liter... So refill every 3000 kilometers? On average.

Folks, Creative Master Northcord has finally launched the Scania Omnicity ukbus9001

If you are interested or would like to place an order for 1 unit, please PM me!
ACx -
AdBlue consumption is 5%-8% of diesel consumption, i.e. if the engine uses 40L of diesel per 100km, 2-3L of AdBlue would be required in addition.

the bus is at C&C now BUT...
SBST OC is not at C&C today

Oh finally the SBST OC is somewhere else now rather than C&C as usual.Guess everybody is gonna get very excited now as to where it is going next. -

Taken the Mercedes O530 buses in London, you guys will definitely love the bus. Hopefully SMRT can maintain them well, look at their current OC500LEs, some of them seem to be falling apart.
-
OC500LEs 1st fault,Bodywork from Gemilang(No pun intended) but seriously i joyride of of the 85xx KUBs.New buses but bodywerk vibrate like hell..Maybe SMRT learn that cheap thing does not necessarily good.Look at 0405/G with Hispano bodywork.Look how sturdy and strong the body is.

its come with voith gearbox again?? i want allison gearbox xD

why allison? Voith good what, can hear the whining of the retarder.. btw today only Citaro was parked inside C & C only, SBST OC gone!
