Product of the Week – Mitsubishi Tier 4 Diesel Engines Coming Soon

Oct. 2, 2012
The new D03CJ (pictured), D04CJ and D04EG small diesel engines from Mitsubishi Heavy Industries provide Tier 4 regulation-compliant solutions in the 25- to 99-hp output range and will begin production in 2013.

The new D03CJ (pictured), D04CJ and D04EG small diesel engines from Mitsubishi Heavy Industries provide Tier 4 regulation-compliant solutions in the 25- to 99-hp output range and will begin production in 2013.

Featuring a three-cylinder design, the D03CJ produces a maximum output of 55 hp and a maximum torque of 165 Newton meters at 1,800 rpm. The four-cylinder equivalent, the D04CJ, produces a maximum output of 74 hp and a maximum torque of 230 Newton meters at 1,800 rpm.

Both engines feature an optimized common rail system with a diesel particulate filter and diesel oxidation catalyst for Tier 4 compliance. Common MHI goals when developing new engines are to achieve a more compact design without sacrificing power, while also lowering fuel consumption. Compared to the previous Tier 3 compliant models being replaced, the D03CJ and D04CJ offer a smaller displacement, while output has been increased. Fuel efficiency is also 16-percent better than previous engines.

“Mitsubishi has developed its Tier 4 engines off of the same Tier 3 engine footprint to save equipment manufacturing time and resources,” says Harold Kabel, small engine sales manager, Mitsubishi Engine North America. “Therefore, there is no re-engineering time or costs to the equipment manufacturer to implement the new Tier 4 engines.”

The new Tier 4 interim, four-cylinder D04EG delivers a maximum output of 99 hp and a maximum torque of 375 Newton meters at 1,600 rpm, with a power density of 0.22 kW/L. The engine utilizes a common rail system including an exhaust gas recirculation system and a DPF and DOC for Tier 4 interim compliance. Compared with the Tier 3 engine it replaces, the D04EG offers 12-percent improved fuel economy. www.mitsubishi-engine.com/
