Euro 2 B Series


130 to 235 PS
Cummins one-litre-per-cylinder B Series engine family has created a standard which others have sought to follow. It enjoys unprecedented popularity in light to middleweight trucks and midi-bus applications, where it has raised operator expectations to new levels, especially on durability.

Evidence of the 5.9 litre six-cylinder B Series success is clear in a host of diverse applications. More trucks and buses in Europe are powered by the Cummins B Series than by any other competitive engine in the same performance class.

Modest weight, compact dimensions and the B Series relative simplicity of construction, with fewer components than comparable engines, appeal strongly to vehicle operators. The B Series benefits from highly responsive turbocharged performance across the range, perfectly matched to the engine, with wastegates fitted on ratings over 200 PS.

A reputation for trouble-free working under the toughest conditions - typically stop-start urban duty-cycle - further enhances the B Series attractions. Continuous evolution of an inherently successful design has kept the B Series ahead of its rivals, with power and torque curves shaped for excellent driveability combined with fuel economy. In specialist applications where installation space is restricted, the four-cylinder 3.9 litre B135 is available with an impressively high power density.
