In every corner of the globe and every construction zone, chances are good that you'll find Cummins B Series engines hard at work. Over 3 million B Series engines are currently in use, from chippers to welders to skid steer loaders. Our mechanical B series engines are small enough to fit the equipment but big enough to handle the job. Three different models are available, the four-cylinder B3.9 and B4.5 plus the 6-cylinder B5.9. Ratings range from 80-173 hp, with varying combinations of turbocharging, natural aspiration and charge air cooling for optimal performance. Plus, the B Series is designed to minimize downtime for maintenance.

For everyday performance, every month and every year, Cummins B Series engines are tough to beat. Whether you're laying down hot asphalt on a sweltering summer afternoon or digging a trench in the middle of winter, Cummins B Series has the power you need and the reliability you demand.
The B3.9 shares the same technology platform with the B5.9, our most popular engine ever, with performance optimized across a wide power band.
The B4.5 is identical in exterior dimensions to the B3.9 but features a longer stroke for more power and better low-end torque. It is offered with a choice of natural aspiration or turbocharging, to meet your power demands.
The B5.9 is a six-cylinder in-line design that uses 40% fewer parts than traditional diesels, thanks to its unitized design. Like all B Series engines, it is a proven power plant with mechanical fuel injection that meets ecological concerns in a highly efficient package.

Maintenance Intervals
B Series engines have been designed for reduced maintenance with plateau-honed cylinders, an innovative ring pack design and edge-molded gaskets for significantly reduced oil consumption. With Cummins B Series, little or no top-off oil should be needed. Oil change intervals can be extended up to 500 hours. And the B Series uses durable, reliable rotary fuel pumps for strong performance in every kind of weather condition.
