The MBE 900 has been the premium engine choice for a wide range of medium-duty and vocational vehicle buyers, powering the needs of food and beverage distributors, pick-up & delivery, fire and rescue departments, refuse fleets, tow truck operators, construction companies and others. Nearly 600,000 MBE 900 engines are in service today, more than 100,000 of which are in North America alone.

With the changes required to meet the EPA's 2007 diesel-emissions mandate, the new MBE 900 - now a full 7.2 liters - will continue to serve its diverse customer base, offering a wide range of power ratings. With this broad spectrum of choices, buyers can spec the most economical, and best matched, components to fit their specific applications. Less money invested, lower operational costs equals a better bottom line.

Tightening Emission Standards

The EPA has been reducing diesel emissions for the past 30 years. The 2007 regulations demand changes in both fuel and engine technology. The new regulations dramatically reduce nitrogen oxide (NOx) by 55 percent and particulate matter (soot and ash) by 90 percent. We achieved the first target by optimizing the existing Exhaust Gas Recirculation (EGR) system and the second by adding an Aftertreatment System, comprised of a Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF).

Exhaust Gas Recirculation (EGR)

The exhaust gas recirculation system has been optimized to dramatically cut NOx formation by routing a measured amount of exhaust flow to the cylinders to lower combustion temperatures. Lower temperatures result in lower NOx levels without the negative effects of retarding engine timing. The EGR valve has been moved to the top of the engine for improved serviceability.

SMART Fuel System®

The new SMART Fuel System adds to the performance and cleanliness of the 2007 MBE 900. It features electronically controlled injection nozzles capable of multiple injections per combustion cycle.

Detroit Diesel Electronic Control (DDEC) VI

Detroit Diesel set the benchmark for diesel engine electronics. Now, they're raising the bar with the sixth generation DDEC VI electronic engine management system. It employs a more powerful microprocessor, increased memory and enhanced diagnostics. The DDEC VI is capable of monitoring and managing all engine functions, including the Aftertreatment Systems required for 2007 emissions. DDEC VI is a key part of the strategy to achieve greater operating efficiency and cleaner exhaust emissions.

Dual-Stage Turbocharger

The high-performance version of the new MBE 900 employs a dual-stage turbocharger to maximize throttle response and combustion efficiency. Controlled by the DDEC VI, the turbo automatically - and precisely - adjusts its boost across the operating range, delivering quick and forceful lift on the low end and superb drivability at any engine speed.

High-Tech Grid Heater

The MBE 900 is capable of starting unassisted in temperatures as low as 5 degrees Fahrenheit. For colder temperature operation, down to -20 degrees Fahrenheit, an optional high-tech grid heater controlled by DDEC VI is available. The high-tech grid heater pre-heats air in the intake system before it enters the engine during starting and initial warm-up. This device reduces cranking time in cold weather to increase starter life, reduces white smoke and offers peace of mind.

Maintenace-Free Electrostatic Breather

A new electrostatic breather system removes oil from crankcase vapor before it's vented into the atmosphere. The system sends oil droplets back to the sump where they can continue to serve the engine, reducing oil consumption. And the best thing is, it requires no maintenance.
