PRESS RELEASE

New Short-term Emissions Regulations-compliant Super Great truck debuts

First heavy duty truck on Japanese market to meet regulations
and earn Ultra-low PM Emissions certification
August 26, 2003


Mitsubishi Fuso Truck & Bus Corporation announces the launch of a new Super Great series model, the first heavy duty truck to both meet Japan's New Short-term Emissions Regulations and to earn Ultra-low Diesel Particulate Matter Emissions certification1. The new Super Great will go on sale on 26 August at Mitsubishi Fuso dealerships throughout Japan.
 

Super Great Ultra-low PM model regulatory compliance
  • First heavy duty truck in Japan to comply with the New Short-term Emissions Regulations (2004 Emissions Regulations)
  • First heavy duty truck in Japan to gain Ultra-low Diesel PM Emissions certification
  • 8-Tokenshi and LEV-6 low-emissions vehicle designation (see footnote 3)
  • Compliance with Automobile NOx & PM Control Law
 

Power & Ecology

Mitsubishi Fuso has built the cleanest heavy duty truck on the Japanese market. The Super Great Ultra-low PM model marries together the company's advanced New Environmental Engine and a new continuous-regenerative diesel particulate filter (DPF) to reduce PM emissions by 75% over the New Short-term Emissions targets. The new model also returns outstanding fuel economy and stay-on-the-road reliability without sacrificing any of its class-topping power output and low noise qualities.

I.Main product features

A.Compliance with regulations

1. New short-term emissions regulations (2004 Emissions Regulations)
The marriage of Mitsubishi Fuso's new Environment Engine with a new continuous-regenerative DPF2 enables the Fuso Super Great to comply at an early date with the New Short-term Emissions Regulations (for vehicles of GVW 12-tons and over) due to come into force in the fall of 2004.

2. Ultra-low diesel PM emissions certification
Ultra-low Diesel PM Emissions certification is a nationally regulated system applying to New Short-term Emissions-compliant vehicles that also achieve major reductions in PM. The Fuso Super Great is the first heavy duty truck in Japan to gain certification under this system.

3. Compliance with other regulations
The new Super Great Ultra-low PM model also complies with the following:
  • 8-Tokenshi3 and LEV-6 designation4
  • Automobile NOx & PM Control Law
  • Mandatory speed governor
  • 2001 Noise Regulations
  • Mid-term Brake Safety regulations

B.Advanced environmental technology

1. New "environment engine"
The new Mitsubishi Fuso "Environment Engine" adds a number of advanced features to its highly appraised MIQCS5 combustion and high-pressure common-rail injection systems to make it the cleanest performing diesel power unit in the heavy duty truck class. The new technologies include, a high-precision electronically controlled cooled EGR system that realizes a significant decrease in PM, a positive crankcase ventilation system (PCV) that recirculates blow-by gas6 to the intake manifold and an on-board diagnostics system (OBD). These innovations do nothing to detract from the legendary low-consumption, high output and low-noise qualities of Fuso engines

 (1) MIQCS (Mitsubishi Innovative Quiescent Combustion System)
Mitsubishi's proprietary combustion control system maximizes air and fuel mixing and combustion efficiency by injecting fuel under high-pressure into large diameter combustion chambers. The increased combustion efficiency over conventional combustion systems, which rely on the air flow within the chamber, reduces in-cylinder NOx and particulate matter, and also improves fuel economy.

(2) High-pressure common-rail fuel injection system
The Environment Engine employs a common-rail high-pressure fuel injection system that optimizes fuel injection for all engine loads and driving conditions. Working in conjunction with the MIQCS combustion control system, this technology significantly reduces in-cylinder PM.

(3) Cooled EGR
The new EGR system gains a water-cooled cooler and features more precise control of the EGR valve operation. The improved system recirculates optimum quantities of cooled exhaust gas to the engine, thereby lowering the combustion temperature and reducing NOx emissions.

(4) PCV7 blow-by gas recirculation
Super Great uses a positive crankcase ventilation system that recirculates blow-by gas to the intake duct. This environment-friendly feature prevents the release into the atmosphere of combustion gases that can leak from the engine.

(5)On-board diagnostics
Super Great employs an on-board diagnostics system that monitors the operating status of the EGR system as well as any trouble in emissions reduction systems caused by wiring circuit malfunctions. A warning light alerts the driver in the event of trouble.

2. Continuous-regenerative DPF
Designed for use with low-sulfur fuels, the new continuous-regenerative DPF8 comprises a powerful, high-capacity oxidizing catalyst and PM filter that efficiently break down and trap PM emissions.

The DPF works in conjunction with Mitsubishi Fuso's new Environment Engine that significantly reduces in-cylinder PM. A considerable proportion of engine-out PM emissions is initially broken down and purified by the powerful oxidizing catalyst that forms the first stage of the PM after-treatment system. This reduces the load on, and limits the build up of PM in, the filter downstream of the catalyst. Preventing clogging of the filter under low exhaust gas temperature conditions, this eliminates the need for forced PM oxidation that adversely impacts fuel economy. The new DPF is now maintenance free after optimization of filter pore size prevents the accumulation of lubricating oil ash emitted from the engine thereby eliminating the need for periodic cleansing.
