LOUISVILLE, Ky. — Detroit Diesel says it’s ready for 2007 and will be offering a full range of horsepower ratings for heay- and medium-duty applications.

“We’re definitely ready for EPA ’07,” Carsten Reinhardt, president and CEO of Detroit Diesel Corporation said at the Mid-America Trucking Show. “We have been working on not just meeting the new emissions standards, but enhancing our three engines set to launch next January. We also have our service, technical support and manufacturing teams ready to support the engines.”

Detroit Diesel will continue offering its Series 60 flagship engine as well as the MBE 900 and MBE 4000. As with all ’07 engines, the new Detroit Diesels will feature an aftertreatment system consisting of a diesel particulate filter (DPF) and a diesel oxidation catalyst (DOC). They will also continue to use exhaust gas recirculation (EGR) to meet the stringent new EPA emissions standards.

Detroit Diesel officials say the new Series 60 will consume nearly 40 per cent less oil thanks to the introduction of a new piston design, changes in oil control ring geometry and a smoother bore finish on the cylinder liner.

The ’07 Series 60 is also equipped with an improved variable geometry turbocharger the company says can automatically and precisely adjust its boost across the operating range, delivering quick lift on the low end where turbo lag would otherwise occur.

A new fuel injection system is also in store for the 2007 Series 60, which will add to the performance and cleanliness of the engine, the company says. The revamped fuel injection system features dual solenoid electronic unit injectors that provide exact fuel metering and enable independent injection pressure control.

Detroit Diesel is also introducing a new generation electronic control system – DDEC VI. The new system includes a more powerful microprocessor, increased memory and enhanced diagnostics, officials say. DDEC VI can monitor and manage all engine functions including the aftertreatment system.

“The 2007 Series 60 represents a tremendous amount of investment, design, engineering and manufacturing to bring a solid and highly reliable and durable product to market,” said Tim Tindall, director of the EPA 07 program for Detroit Diesel. “I’ve been with Detroit Diesel for over 30 years and this is by far the most extensive program in terms of testing and preparedness that I’ve seen.”

Meanwhile, the MBE 900 and MBE 4000 have also been retooled for 2007, the company said at the Mid-America Trucking Show.

“Our MBE 900 and MBE 4000 engines will be ready for the road next Janary,” vowed Reinhardt. “They are reliable and durable and will deliver the power our customers have come to expect while meeting strict environmental standards.”

Reinhardt said all 2007 engines have been through rigorous test cell and real-world testing.

The MBE 900 medium-duty engine will feature a standard displacement of 7.2 litres and will be available in ratings of 190-300 hp and between 520-860 lb. ft. of torque.

The MBE 4000 heavy-duty engine has new torque ratings across its power range, which now runs from 350-450 hp with 1,250-1,650 lb. ft. of torque. The MBE 4000 comes with a standard engine brake that provides up to 370 of braking horsepower.

The MBE 900 and MBE 4000 engines will also use the DDEC VI electronic control unit found on the Series 60. This will allow fleet managers to streamline diagnostic tools, technician training and parts availability, Detroit Diesel officials said.

Detroit Diesel engines will also adopt a new electrostatic breather to address crankcase emissions requirements. The device will take oil out of the crankcase vapours and reutrn the oil back into the crankcase. The device does not use a filter and will require no routine maintenance, the company said.
