Fuel consumption
-
I wonder what are the fuel consumption of the bus types.
-
no data, but SMRTB's O405 was quoted by newspaper many years ago to go about 2km per litre of diesel on average. for svc 171, with a one-directional distance of about 32.8km, it will cost about $17, without considering other costs like manpower etc. imagine how many pax u need to generate revenue!Originally posted by SBS3624G:I wonder what are the fuel consumption of the bus types.
but fuel consumption depends on many other conditions/factors beyond just bus types.
let's say the B10BLE-CNG buses running in singapore. they consume more fuel per unit of distance as:
- it runs on the Otto engine heat cycle, which has a max. thermal efficiency of 37% compared with a Diesel engine heat cycle with 45% efficiency
- the tank on top, though made from an aluminium-carbon fibre composite to reduce mass and weight, weighs about 700kg
- compared to a volumetric gallon of diesel fuel, there is less energy in an energy gallon equivalent of natural gas
so u see. -

I supposed, bendys and double-decks consume more fuel than normal-length single decks right? , since they are heavier... -
generally yes.Originally posted by bus911:

I reckon MB0405s consume more fuel as they are more powerful at 11 000+ CC.Originally posted by ^tamago^:no data, but SMRTB's O405 was quoted by newspaper many years ago to go about 2km per litre of diesel on average. for svc 171, with a one-directional distance of about 32.8km, it will cost about $17, without considering other costs like manpower etc. imagine how many pax u need to generate revenue!

oh yes. fyi, for "B10M", the "10" means a ~10-litre engine chassis (or 9.6L in all cases of B10M's) and "M" means a mid-mounted engine.Originally posted by iveco:B10M (all Marks) Eng Cap: 9.6L
thus, B10TL's also uses a ~10-litre engine (or 9.6L, again) configuration. "T" could stand for tri-axle, "L" is for low-floor variant.
also, B10BLE-CNG uses a 9.6L engine, has a "B" back-mounted engine, is a "LE" low-entry variant and is a "CNG" variant of the B10BLE. -
The "T" in B10TL stands for "transverse". That means, the engine and gearbox are mounted perpendicular to the chassis. This is the standard configuration on most modern DDs.
The B10B was developed as Volvo's successor to the Leyland Lynx. The second "B" stands for a rear-horizontal engine. This differs from the B7R, where the "R" stands for a rear-vertical engine. -
