SMRT New Euro-V Mercedes-Benz OC500LE WAB bus (Part 1)

last SG · 2008-04-30T00:15:45+00:00

From news: the new buses will go on the streets in 2 weeks time goooood. by then my MYE has long ended. =D

nenepokey SG

anyway did u see any rego on the bus? when going/returning to/from MB Svc Ctr?

Raraken SG

WLDEP?

WOOHOOO!

I just hope that WLDEP maintenace is going to be better. And this bus had better not be a depot specialty.....or a service one.

off_service SG

The OC500LEs are staying at WLDEP.

More than 1 unit?

JJxJJ SG

More than 1 unit?

they tendered 66 i thought

it is still 'SMRT'..

Raraken SG

What's with Wiki stating that our OC500LEs are CNG-powered? They are diesel, right?

Yes, they are just diesel buses with a Euro 4 Engine (without additives), the Euro 5 comes about when they add the urea additive (AdBlue).

Yes and the mechanics aren't experienced with AdBlue or Ad-blue I don't know and it will take a few months for them to familliarise themselves with the bus as it is way different than the other Mercs which are Euro-I and Euro-II

Scania SG

Urm? AdBlue is an additive, not a machine. The technology, Selective Catalytic Reduction (used by Volvo, Mercedes Benz and Cummins and as an option by MAN and Caterpillar) is incorporated into the engine. The only thing the mechanics need to do is to learn how to maintain a new engine, why learn AdBlue when they are not chemical engineers.

Who on earth tell you this?Crap sial!Sometimes i do get fed up with SMRT Tech,All they know is Merc only.

Guys, please stop bickering.

Let me clarify a couple of things. Firstly, AdBlue is a urea additive that is injected into the exhaust gases in an SCR system to neutralise, among other things, nitrogen-oxides (NOx) to allow an engine to undercut Euro 4, Euro 5, and EEV emissions regulations. DaimlerChrysler calls this technology "BlueTec". Mechanics will need to familiarise themselves with the maintenance of the SCR injection system as well as additional OBD fault codes associated with it. Fuellers and/or drivers will also need to familiarise themselves with the refuelling procedure.

Secondly, AdBlue and BlueTec injection is required to meet not only Euro 5 and EEV, but Euro 4 as well, because the base engine without SCR is a Euro 3 engine. If a Mercedes-Benz Euro 5 engine runs out of AdBlue solution, it will drop into what's known as "limp-mode" - power and torque output is dramatically decreased until the AdBlue tank is topped up.

Hmm....and how much does this additive cost? Will the company absorb the cost or will it be passed down to commuters? Fuel prices have gone up, bus fares is very likely to go up too? Will it be soon enough to hold the new buses until the fares are increased?

Powered_By_CNG SG

Because the SCR system reduces NOx emissions to levels well below the level set by Euro 5/EEV, it is now possible to allow to engine to perform to its maximum potential. Euro 5/EEV engines with SCR do not require power and torque derating to obtain good emissions performance and are therefore more efficient and economical. The AdBlue injection quantity is approximately 8-10% of diesel consumption (e.g. you will use 4.5L of AdBlue if you use 45L of diesel per 100km), but diesel consumption is decreased also by about 10% in comparison to Euro 3 engines. At this point in time, AdBlue costs approximately 2/3 of the price of diesel per litre. This means that operating a Euro 5 bus will cost about the same as operating a Euro 3 bus without EGR or SCR.

Dave

Thanks for the insight, Dave.

Yes, thanks Dave for your contributions. (:

the one with "SMRT" rego is still at wldep when i left depot at about 7.15pm today.. so tat means there is one at wldep and another new one at amkdep??

There was no new Merc in AMDEP when I passed by there at 4+ in the afternoon.

AMDEP can liao, not a need for the k

TIB436J SG

WHEN ARE THE OC500LE ARE GOING TO BE OUT?..... HAVE BEEN WAITING FOR THE PAST 1 MONTH ALREADY. I USE TO FREQUENT SV 851 AND 854. I REALLY HOPE THE FASTER PHRASE IN THESE BUSES.
