MBE 900 Medium-Duty Engine Performance

Smart and Strong

You expect brains and brawn from a medium-duty application diesel engine — and the MBE 900 brings the performance. It's a true standout, driven by the smarter design and reliable power that can only come from a Detroit Diesel.

Practical Performance

We understand what you need from a medium-duty engine — and the MBE 900 gets down to the business of delivering it. Some of the reasons it can:

Optimized Exhaust Gas Recirculation (EGR)

The MBE 900 takes super-heated exhaust and sends it back through the engine, where it's water-cooled and routed back to the intake manifold. Then, the Aftertreatment System's filtration process cleans the exhaust before re-entry into the atmosphere.

Precise Engine Control

Staying on top of things at all times is a given with advanced DDEC VI electronic controls, the newest version of Detroit Diesel's breakthrough monitoring and management technology. Using sophisticated diagnostics and analytics, the DDEC VI system monitors and reports any changes in your rig's operation so you can react quickly and confidently.

Fueled by Innovation

The SMART Fuel System knows what all drivers look for — better performance and improved fuel economy. And it delivers with DDEC VI-controlled high-pressure solenoid injectors capable of multiple injections per combustion cycle. Translation: improved performance and perfect fuel control, not to mention reduced engine noise.

Harder-Working Parts

The MBE 900 comes equipped with a multi-functional fuel-filter that features two filtration stages: a fuel priming valve and a fuel-water separator, all contained in a single, standard assembly. Because smarter parts should tackle more than one job.

Smooth Acceleration

With available ratings up to 250 HP/660 lb-ft., the MBE 900 has plenty of power to satisfy most medium-duty applications. And the high-torque rise architecture is perfectly suited to gear-fast/run-slow powertrain matching, optimizing fuel economy.

The Power to Stop

Nothing gives you peace of mind like reliable braking — and the MBE 900 can be equipped with two optional engine brakes. The exhaust brake option provides up to 140 BHP, while the exhaust/compression brake combination delivers best-in-class 180 BHP.
