The Scania KNF range is the current modular range of bus and coach chassis from Swedish commercial vehicle manufacturer Scania. The range is divided into three main series based on the engine location; the rear longitudinal Scania K-series, the rear transversal Scania N-series and the front-mounted Scania F-series. They are again divided into a total of eleven chassis types, including the K EB, K IA, K IB, K UA, K UB, K UD, N UA, N UB, N UD, F HA and F HB. The K- and N-series have been manufactured in Sweden since 2006, while the plant in Brazil has manufactured the K- and F-series since 2009.
History
[edit]The range was first presented on Busworld 2005[1] in Kortrijk, Belgium and models were available from 2006.
Scania Latin America in São Bernardo do Campo (Brazil) had rebranded their 4-series bus chassis range to type designations identical to the new range in January 2005, more than half a year before the new range was launched in Europe.[2][3] The rebranding was in line with their similar rebranding of 4-series trucks to replicate the designations of the PRT-range. However, they were marketed similarly to the trucks, with only the engine location letter, K and F, followed by the power code, like F 310 and K 420. The rebranded 4-series was manufactured there for several years until the K-series was finally launched in November 2008 with production starting in January 2009,[4] and the F-series in July 2009.[5] In Latin America, the current range is still marketed in the same way as the rebranded 4-series, focusing on the power code and often disregarding the actual chassis types, which are instead mentioned in subtext.
Engines
[edit]When introduced, the range was available with Euro IV-compliant 8.9-litre (8867 cc) 5-cylinder engines (DC9) with output of 230 hp (1050 Nm), 270 hp (1250 Nm) and 310 hp (1550 Nm) as well as the 11.7-litre (11705 cc) 6-cylinder engines (DC12) with output of 340 hp (1700 Nm), 380 hp (1900 Nm), 420 hp (2100 Nm) or 470 hp (2200 Nm), the latter being a DT12 turbo-compound engine. For the 5- and 6-cylinder engines Scania is using exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) systems to fulfill the legal Euro emission standards.
In 2008, Scania released upgraded Euro V engines in order to meet these regulations. The 5-cylinder DC9 (later DC09) engines featured a larger bore and displace 9.3-litres (9291 cc) instead of 8.9-litres. The new DC13 engines feature both a larger bore and a longer stroke, and therefore displace 12.7-litres (12742 cc) instead of 11.7-litres. Some engines also received slight performance improvements, for example the DC9 engine that outputs 310 hp (1550 Nm) was upgraded to 320 hp (1600 Nm).
With the introduction of Euro VI engines in 2013, the DC09 outputs 250 hp (1250 Nm), 280 hp (1400 Nm), 320 hp (1600 Nm) and 360 hp (1700 Nm), while the DC13 outputs 410 hp (2150 Nm), 450 hp (2350 Nm) and 490 hp (2550 Nm).[6] Euro III, IV and V engines are still available for export markets.
For alternative fuels, the 9.3-litre was available as the OC9 CNG engine with power outputs of 270 hp (1100 Nm) and 305 hp (1250 Nm), which from the introduction of Euro VI was replaced by the OC09 with power outputs of 280 hp (1350 Nm) and 340 hp (1600 Nm). The 8.9-litre is available as the ethanol fueled DC9 E02 with a power output of 270 hp (1200 Nm).

Chassis type
[edit]The chassis type designation uses only the engine location, type of transport and chassis adaption. There is a space between the engine location and the type of transport.
Chassis types
[edit]Scania F HA
[edit]The F HA8x2NB is a bi-articulated front-engined bus chassis manufactured by Scania Latin American since it was launched in October 2015. It has a "puller" configuration, meaning that the drive axle is the second axle of the vehicle, as opposed to most rear-engined articulated buses where the rear-most axle is the drive axle. The F HA is intended for use in BRT systems with high-level platforms where the height of the chassis is not in the way of accessibility. Examples have been bodied by Neobus equipped with a 360-horsepower Euro V engine (F 360 HA8x2NB), has 28 metres length, five pairs of doors and a capacity for 270 passengers.[9][10]
Scania F HB
[edit]The front-engined F HB was first presented by Scania Latin America at the Transpúblico fair in São Paulo on 14−16 July 2009.[5] The most common variant from the start was the F HB4x2HZ, a two-axle, high-built chassis with leaf-spring suspension on all wheels.[11] A tri-axle, high-built variant, the F HB6x2HA, with leaf-suspension at the front and air suspension at the rear has also been available,[12] as well as the simpler F HB6x2HZ with only leaf-spring suspension.[13] Later also the F HB4x2NZ with normal chassis-height is available.[14] The F HB has been delivered with power ratings ranging from 230 to 310 hp, and is currently available with Euro V engines.
Scania K EB
[edit]The K EB chassis have independent front suspension and are used for top end coaches (4x2, 6x2 and 6x2*4). 280−490 hp.
Scania K IA
[edit]The K310IA is an articulated intercity bus chassis available in Latin America as 6x2/2 and 8x2/2. TransJakarta has one K340IA (CNG) (Fleet no. TJ 0187) and 51 K320IA (CNG) (TJ 0188-0239)
Scania K IB
[edit]The K IB are the intercity bus variants but are also used for coaches. Available as 4x2, 6x2, 6x2*4 and 8x2. 270−420 hp.
Scania K UA
[edit]The K UA are the articulated (6x2/2) citybus variant which can be ordered with the two stronger 9-litre diesel engine variants or the strongest 9-litre CNG engine variant. 270−360 hp.
(Has more on operators.)
Scania K UB
[edit]The K UB are the rigid (4x2 or 6x2*4) citybus variant which can be ordered with all 9-litre engines. 230−360 hp. A pair of K380UB 6x2*4 with the 11.7-litre engine has also been made for a customer in Norway.
(Has more on operators.)
Scania K UD
[edit]The K UD is the double-deck citybus variant with an 8.9-litre DC9-18 5-cylinder 310 hp Euro IV compliant engine (hence the 310 in K310UD), or a 9.3-litre DC9-29 5-cylinder 280 hp Euro V compliant engine. The 'U' indicates the bus is designed for urban application, the 'D' points out the chassis is made for a double decker. 280−320 hp.
(Has more on operators.)
Scania N UA
[edit]Scania N UB
[edit]Scania N UD
[edit]The N UD4x2EB (N230UD, N270UD) two-axle double-decker. The double-deck variant is mainly built for use in the United Kingdom, and is available with Optare OmniDekka, Optare Olympus and Alexander Dennis Enviro400 bodywork, it could also be fitted with Scania's own bodywork and sold as the OmniCity.
