6B5.9

The B5.9 is a six-cylinder in-line/rotary fuel system 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.

Painstaking attention to details makes every B Series engine reliable and durable. They'll be on the job, for years to come.
