Mitsubishi Fuso To Exhibit At
2010 Automotive Engineering Exposition
In Yokohama, Japan

Kawasaki - Mitsubishi Fuso Truck and Bus Corporation (MFTBC), one of Asia’s leading commercial vehicle manufacturers, will exhibit its newly developed heavy-duty engine 6R10 and exhaust gas after-treatment system BlueTec® at the 2010 Automotive Engineering Exposition in Japan. The event will be held Wednesday, May 19, through Friday, May 21, at Pacifico Yokohama. These advanced technologies are already incorporated into MFTBC’s new Super Great heavy-duty truck introduced on April 22.

Mitsubishi Fuso Displays at Automotive Engineering Exposition

1. Newly Developed Heavy-Duty Engine 6R10

The 6R10 engine to be displayed at the event leverages the know-how of Daimler Trucks business units in the United States, Europe and Japan to achieve superb fuel efficiency, dynamic performance, clean emissions and greater reliability. The 6R10 is based on a heavy-duty engine concept developed jointly by Daimler Trucks business units in the United States, Europe and Japan.

This new heavy-duty engine complies with the Japan’s 2009 New Long Term Emission Regulations (JP09), the most stringent in the world. It also provides higher performance than before, achieving both emission gas reduction and fuel efficiency improvement.

A key feature of the engine is the newly developed X-Pulse, an intensified pressure common rail system. X-Pulse precisely controls the fuel injection rate to realize fuel injection that is optimized depending on engine load and rotations which vary according to driving conditions. The system is also capable of high-pressure injection at pressures more than 30% higher than conventional common rail systems. These technologies make possible precise injection control at all engine speeds, resulting in cleaner exhaust emissions and improved fuel economy.

2．BlueTec® System for Exhaust Gas After-treatment

MFTBC will also display its BlueTec® system, just introduced for the Super Great heavy-duty truck on April 22. The BlueTec® system includes an urea selective catalytic reduction (SCR) system and diesel particulate filter (DPF). Reducing both nitrogen oxide and particulate matter, this is a key commercial vehicle technology for contributing to global environment preservation.

BlueTec® is the solution to overcome the traditional fuel economy penalty associated with NOx reduction, and achieve both fuel efficiency and emissions reduction.

This system collects PM to be burnt for elimination through ‘regeneration DPF’ combining oxidation catalyst and SiC ceramic filter. The BlueTec® urea SCR system - comprised of SCR catalytic muffler and an urea water dozing nozzle - decomposes the remaining NOx into harmless nitrogen (N2) and water (H2O) through the chemical reaction of the ammonia which is generated from the urea water.

With this BlueTec® system (DPF + urea SCR), the engine unit focuses on achieving high combustion efficiency, realizing both CO2 reduction due to fuel economy improvement and at the same time PM and NOx reductions.

BlueTec® technology was first introduced by Daimler Trucks in 2005 in Mercedes-Benz heavy-duty trucks. Daimler Trucks units have now sold more than 250,000 BlueTec®-equipped units, with 400 billion kilometers of travel accumulated; so endurance and reliability has been established. The BlueTec® technology installed into the new 6R10 engine incorporates MFTBC’s own research and development inputs, for optimal performance in the new Super Great.
