The Scania 4-series bus range was introduced by Scania in 1997 as a successor to the 3-series bus range. The 4-series bus range was first presented in September 1996, when the integral low-floor city bus OmniCity was revealed.〔(Low-floor bus first out in Scania's new bus range ) ''Scania'' 3 September 1996〕 Production of the chassis range started in second half of 1997, and by the end of 1998 all worldwide production facilities had changed from 3-series to 4-series.〔(Scania's 4-series highway buses launched in Latin America ) ''Scania'' 8 September 1998〕 Unlike the 3-series, which was a range of 45 different chassis models, the 4-series is one basic chassis with different modular configurations depending on usage and customer needs. At launch there were a total of seven major configurations, presumably the F HB, K EB, K IB, L IB, L UB, N UA and N UB. These were later followed by the F HA, K UB, L IA, L UA and N UD. The first letter describing the position of the engine, and the last two letters describing areas of use. In marketing of the 4-series, Scania have generally only used the engine position (F/K/L/N), the engine displacement (9/11/12) and the series number (4), which is why we know them as F94, F114, K94, K114, K124, L94 and N94. The 4-series was superseded in 2006 by the new Euro 4 compliant bus and coach range consisting of the K-series, N-series and F-series. Some 4-series products have been available for a couple of years after this. ==Type designation breakdown== ;Engine location * F: chassis with longitudinal engine ahead of the front axle * K: chassis with longitudinal engine behind rearmost axle, centrally mounted * L: chassis with longitudinal engine behind rearmost axle, inclined 60° to the left * N: chassis with transverse engine behind rearmost axle, inclined 60° to the rear ;Engine series *9: DSC9/DC9 *11: DC11 *12: DSC12/DC12 ;Development code *4: 4-series ;Type of transport * E: coach, long distance, high comfort (K chassis only) * H: intercity, short to long distance, uneven surface (F chassis only) * I: intercity, short to long distance, normal comfort * U: urban, short distance, normal comfort ;Chassis adaption * A: articulated bus * B: normal bus * D: double-decker bus ;Wheel configuration * 4X2: two-axle bus * 6X2: tri-axle bus * 6X2/2: tri-axle articulated bus * 6X2 *4: tri-axle bus with steered tag axle behind drive axle * 6X2/4: tri-axle bus with steered tag axle in front of drive axle (one known example, see K94UB) * 8X2: quad-axle bus (K IB chassis in Latin America only) ;Chassis height * E: low front and rear (N chassis only) * H: high front and rear (F chassis only) * L: low front, normal rear * N: normal front and rear ;Suspension * A: leaf-spring suspension front and air suspension rear (F HA chassis only) * B: air suspension front and rear, rigid front axle * I: air suspension front and rear, independent front suspension (K EB chassis only) * Z: leaf-spring suspension front and rear (F chassis only) ;Power code Approximation of the power rating in hp to the nearest ten. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Scania 4-series (bus)」の詳細全文を読む スポンサード リンク
