Mitsubishi Fuso Unveils Advanced, New Powertrain for Light-Duty TrucksJuly 20, 2010 Overall: Mitsubishi Fuso has previewed its future light-duty truck powertrain technology in Japan,including its newly developed 4P10 engine, the DUONIC transmission and the BlueTec,exhaust aftertreatment system. It will be installed in the next generation light-duty truck product line, which will debut in the Japan market. In principle, this will be the powertrain which will roll out in the international markets at different timings and with some regional adjustments including compliance to regional emissions regulations. About New Powertrain System: To meet different emission regulations in different countries and higher performance required for light-duty trucks, the new powertrain consists of a light and highly efficient three-liter "4P10" diesel engine with low fuel consumption; the BlueTec® emissions reduction system combining a urea selective catalytic reduction (SCR) system and regeneration-control diesel particulate filter (DPF), incorporated in a light-duty truck for the first time in Japan; and the DUONIC dual-clutch transmission, the first ever use of this type of transmission in a commercial vehicle.
1. Newly developed light-duty engine 4P10:
The 4P10 engine has been developed jointly by Mitsubishi Fuso and Italy's Fiat Powertrain Technology (FPT) and has cleared both companies' strict criteria for quality, durability, and fuel economy. It carries the Mitsubishi Fuso brand and has been assigned Mitsubishi Fuso's own model number. The engine is a three-liter variable geometry (VG) turbo diesel engine with in-line four cylinder, adopting DOHC4 valve structure. Flat torque characteristics and higher revolutions significantly enhance drivability.

Newly Developed 4P10 Engine |
| 4P10 Engine Specifications |
|---|
| Engine model | 4P10 | | Cylinder | In-line four | | Air intake method | Intercooler turbo | | Bore x stroke (mm) | 95.8 x 104 | | Total displacement (L) | 2.998 | Key Features/Advantages of 4P10 Engine:
(a) Planned compliance with the latest emission regulations in U.S., Europe, and Japan (b) Piezo injectors adopted for common rail fuel injection system. (c) Variable geometry turbocharger adopted (d) High efficiency EGR Cooler adopted. (e) Environmentally-friendly green filter used as oil filter.
2. First use of BlueTec® emission system for light-duty trucks in Japan
Hundreds of thousands of vehicles with the BlueTec® system are already running in the U.S. and Europe. In Japan, MFTBC has already adopted the BlueTec® emission system in several models, including the new Super Great heavy-duty truck launched in April, the Fighter mid-duty truck, Aero Queen and Aero Ace large tourist buses, and Aero Star large route bus. BlueTec® is a registered trademark of Daimler AG.
In addition to MFTBC’s vehicles in Japan, the BlueTec® system is also installed in Mercedes-Benz passenger cars and trucks elsewhere, and is recognized worldwide as an environmentally-friendly exhaust gas after treatment system. Now, MFTBC is announcing that BlueTec will be installed in the upcoming new generation Canter. This will be the first case to use BlueTec® emission system for light-duty trucks in Japan, and together with the 4P10 engine with high combustion efficiency, the system achieves both fuel efficiency and emissions reduction in parallel Key Features/Advantages of BlueTec®:
(a) Achieving fuel efficiency and emissions reduction. (b) Regeneration DPF. (c) AdBlue® and fuel consumption rate.
3. DUONIC dual-clutch transmission newly developed for application to commercial vehicles for the first time in the world
MFTBC has been developing two-pedal automatic transmission for over 30 years. As a culmination of this long development experience, the company has created the 6-speed automated dual clutch-type manual transmission ‘DUONIC’ to maximize power transmission efficiency for commercial vehicles for the first time in the world. DUONIC achieves a direct acceleration feeling and smooth driving brought by the dual clutch, and also together with newly developed 4P10 engine, it significantly contributes to enhancing fuel efficiency. It combines the comfort of an automated transmission which the efficiency of a manual transmission. MFTBC developed the DUONIC design, built its control programs and also will produce and assemble the components.
DUONIC Specifications:
| Transmission model | M038S6 | | Clutch | Wet clutch | | The number of gears | Forward: 6; backward: 1 |
Key Features/Advantages of DUONIC: (a) Direct acceleration and smooth driving realized by dual clutch. (b) Excellent fuel economy with efficient power flow. (c) Wet-type dual clutch adopted with no need to replace clutches. (d) Creep function added to realize easy drive same as passenger car. (e) Parking range newly added. |
