Originally posted by Powered_By_CNG:Going by the figures obtained by Australian operators who own MAN A69 chassis' fitted with the same engine, the fuel consumption is very similar if only slightly higher than the Mercedes-Benz OC 500 LE. The OC 500 LE is optionally available with a 354hp engine as well which outputs 1600Nm of torque, again with next to no fuel consumption penalty.
There are some characteristic differences between the D 2066 LUH engine and OM 457 hLA engine. The D 20 does not have quite as much torque as the OM 457 at below 1000rpm and the torque drops off quickly after 1600rpm or so as well. The D 20 engines are twin-turbo compared to the OM 457 which has a single turbo but obviously the turbos on the D 20 engine are optimised for strong mid-range performance.
Hmm, is the similarity in fuel consumption due to the less powerful engines having to work harder at a higher rpm (and thus consume more fuel) than the more powerful engines? Woudn't have expected fuel consumption to be somewhat similar, since the extra power needs to come from somewhere.
My personal taste is having engines that have a gradual torque buildup rather than having most of the engine's torque output chucked onto the drivetrain the moment the driver steps on the accelerator. Sounds like my type of bus.

It's the HK MTR A-stock(TCL/AEL) and K-Stock (TCL/TKL).
Here's a video to show the TCL K-stock.

The amount of fuel used is roughly the same, depends on your payload. Cause you need that amount of energy to move a specific load, the energy do not come from the engine, because the energy produced by the engine is from the fuel aka fuel calorific value.
But an engine that is forced to work intensively and labourly, would require a substantial amount of maintenance and ultimately, overhauling. So now it depends which bus, requires more maintenance and overhauling.

Engine is a MAN D 2066 LUH which is a 10.5-litre, horizontal 6-cylinder, twin-turbocharged and intercooled engine with Exhaust Gas Recirculation meeting Euro 5 and EEV emissions standards. Power rating is 235kW (320hp) at 1900rpm and the torque rating is 1600Nm from 1000rpm to 1400rpm. This is a very high performance engine for a rigid city bus!
No, the bus (SMB138Y) only has 270hp. And 320hp for SG roads is just too much.

but i think someone mentioned that the code NL320F/NL323F will mean the bus is equipped with 320hp engine.

The bus is registered as a NL320F, where 320 in the MAN naming convention reflects the engine horsepower. If it had a 270bhp engine it would be a NL273F!

Hmm, now I'm not sure.
take for example SBS8031J, it is a fullsize low-entry chassis and is registered as a MAN 18.240 HOCL-NL as per MAN naming convention for LE chassis which are xx.yyy where xx refers to the GVM of the vehicle and yyy refers to the horsepower rating. H in HOCL stands for rear-mounted engine.
whereas for SMB138Y, it is registered as a NL323F which follows the MAN low-floor fullsize citybus naming convention which is NLxxyF. all low-floor citybuses are rear engined so no need for the rear/front engine designator. NM stands for midibus, NL stands for fullsize and NG stands for articulated.

Anyway where is our MAN 18.240 HOCL-NL SBS8031J?

Laid up.

Yup, I know that but people kept telling me the SMRT MAN is a NL320F with 270HP.

you choose to believe them or believe MAN?

MAN of course.
Wait wait...so SMRT MAN is NL320F (A22) or NL323F?
Originally posted by SMB66X:Wait wait...so SMRT MAN is NL320F (A22) or NL323F?
Should be the NL320F but MAN website i cannot find NLXX0Fs, only got NLXX3Fs.
Originally posted by SMB66X:Wait wait...so SMRT MAN is NL320F (A22) or NL323F?
registered as a NL320F (A22) but on the MAN website, the A22 is classed as a NLxx3F.

If info printed on the brochure is of good accuracy, then yes, SMRT's MAN NLxx3F is of 320HP. Because all new buses with Diesel engines are required to be Euro V now, and for that, MAN only offers the D2066 LUH 320HP Euro V for NLxx3F.

Not correct. For Euro 5 city bus applications, the D 2066 LUH engine is available in 278hp, 320hp and 360hp ratings.
SMB138Y assigned to WLDEP according to one of SLs, on 961 today

Of course lah performance is good,10.5 litre,320hp for a rigid bus not good then throw beside longkang.Actually 278hp from a 10 sub litre bus is good enough.Hope the bus is reliable as the legendary O405s.Hmm WAB MAN bendies??
Aiyo...come out again leh :D
Anyone knows the gearbox of the MAN?
Either ZF6 Speed or Voith 4 speed?
