[Buses in Beijing]福田欧V Foton AUV BJ6123C7C4D <HEV> 北京公交集团 BPT #98535 Line 87 Front-right at Xizhimen Outer
A type BJ6123C7C4D 12m (39 ft.) low-floor diesel-electric parallel hybrid city bus built by BAIC (Beijing Automotive Industry Holding Co., Ltd.) under Foton AUV trademark
In 2008, BPT introduced 10 hybrid-electric buses, two for each of the five models from different manufacturers and carrying various hybrid systems, for trial operations on Line 121 and on Olympic Village shuttles. None of the five models, or more precisely the systems they carried, was proved favorable, leading BPT to seek for other options oversea. The solution was Eaton's parallel hybrid, which later equipped BJ6123C7C4D, the first hybrid-electric bus that offers regular revenue service on BPT routes. With a total number of 800, BJ6123C7C4D ranks BPT's bus model with largest number of units in service.
BJ6123C7C4D adopts a parallel diesel-electric hybrid system and the essential hybrid system Eaton presents. Propulsion from the Cummins ISBe+225B 225hp Euro IV diesel engines drives the Eaton AMT (Automatic Mechanical Transmission) gearbox. Between the automatic clutch and the gearbox fits a permanent magnetic synchronous motor (PMSM) from Eaton with 44kW peak power and 26kW continuous power. Electricity collected from decelerating and braking is stored in the Li-Mn, non-plug-in-rechargeable battery packs, products of Citic Guoan MGL, beneath the last row of passenger seats instead of on the roof. An Eaton control unit commands the entire hybrid system.
The bus is propelled by the motor alone when speed is below 20km/h while the diesel engine takes over the job when speed exceeds. As the result, the bus accelerates from still with a sound very similar to that of an AC trolley-bus. ZF axles provide comfortable rides but unfortunately, due to the AMT gearbox, the gear shifting is not as smoothly as those AT buses do so that passengers are able to feel the presence of the slight dashes. In general, with the advertisements and the working theory introductions posted in and outside the bus, passengers rate BK6123C7C4D a high score.
