UD Trucks Launches Quon Heavy-Duty Models Compliant with 2009 Emission Regulations — Environmental Performance and Fuel Economy Meet New Standards —

Tuesday, April 20, 2010 | Print

UD Trucks Corporation (formerly Nissan Diesel Motor Co., Ltd, President: Satoru Takeuchi) has produced versions of its Quon heavy-duty truck that comply with new emission regulations introduced in Japan in 2009 (“Post New Long-term” regulations). Cargos go on sale on April 20th, 2010, and tractors go on sale on May 10th, 2010. Both models go on sale throughout Japan.

UD Trucks Corporation (formerly Nissan Diesel Motor Co., Ltd, President: Satoru Takeuchi) has produced versions of its Quon heavy-duty truck that comply with new emission regulations introduced in Japan in 2009 (“Post New Long-term” regulations). Cargos go on sale on April 20th, 2010, and tractors go on sale on May 10th, 2010. Both models go on sale throughout Japan. 


In addition to environmental performance, the latest Quon lineup has been developed to meet growing demand for high levels of both fuel economy and driving performance. It features newly developed engines with higher maximum fuel injection pressure to make combustion far more efficient and newly developed transmissions equipped with wider gear ratio. Other features that meet customer demands by supporting enhanced fuel-saving technology and fuel-efficient driving include upgraded ESCOT mechanical electronic control transmission, the nenpi-o [“fuel king”] system providing guidance for improved fuel efficiency, and a multipurpose display with capability to identify vehicle status via the Internet.


The new models also boast an upgraded version of the FLENDS, nitrogen oxide (NOx) and particulate matter (PM) reduction system, which includes a urea SCR catalyst and ultra-high-pressure fuel injection. In 2004 we became the first company in the world to adopt such a system for use on vehicles. By greatly reducing NOx and PM levels, the upgraded system complies with emission regulations introduced in 2009. 


Advanced safety technologies have been introduced to prevent accidents or minimize collision damage, particularly by enhancing brake functions.

1. Key Features
(1) A high-performance, economical power train
a) Newly developed engines (GH11, GH13)

By adopting technology including a light, high-performance variable geometry turbocharger (VGT), the new 11-liter GH11 engine achieves high levels of output and torque similar to those developed by the conventional 13-liter GE13 engine. As well as being smaller in capacity, the new engine is lighter than previous versions.

GH11 engine is adopted in regular vehicles and tractors. Three types of engines are available for regular vehicles that are 350, 380 and 410 horsepower(hp).

While maintaining levels of performance equivalent to the conventional GE13 engine, the new 13-liter GH13 engine has been specially developed for use in tractors.

GH13 engine is adopted in tractors and has two types; 450 and 480hp
b) Newly developed 12-speed transmission

Gear ratios are wider than in previous models, increasing the drive power of low gears used for moving off and reducing engine revs in higher gears used for cruising.
(2) Improved fuel-saving technology
a) New unit injector

Maximum fuel injection pressure has been raised above the previous level of 2,000 bar, and atomization of fuel improves combustion efficiency and reduces PM.
b) ESCOT-V (five) mechanical electronic control transmission

Two-pedal automatic transmission eliminates the clutch pedal, doing away with the need for clutch operation at any point from moving off to stopping, whether in forward gears or reverse.

Economy E/D function changes up gears sooner than normal, supporting fuel-efficient driving by enabling driver to maintain low engine revs.

ESCOT Roll function controls deceleration when coasting without engine brakes after driver takes foot off accelerator. Supports fuel-efficient driving by saving fuel needed for reacceleration.
c) Multipurpose display fitted as standard equipment on all models

Standard equipment on all models to support fuel-efficient driving and safe operation includes the nenpi-o system providing voice and visual driving guidance in real time to improve fuel efficiency and a multipurpose display with capability to identify vehicle status via the Internet.
(3) Improved NOx and PM reduction technology
a) Large exhaust gas recirculation (EGR) unit

A large EGR unit has been used to achieve a simultaneous reduction in NOx.
b) New PM reduction equipment

UD Trucks' own PM reduction equipment furnished with automatic regeneration, the device assures removal of PM due to incomplete combustion.
c) Larger urea SCR catalyst

The NOx-converting urea SCR catalyst has been enlarged to improve NOx reduction.
(4) Further advances in driving safety
a) Advanced “Traffic Eye Brake” system reduces collision damage

As well as a wider range of models fitted with “Traffice Eye Brake”, the system has been enhanced to improve speed reduction in the event of a possible collision from 17 km/h to 20 km/h and a new function which recognizes stationary vehicles and slow the truck to avoid possible collisions has been added.

The “Traffic Eye Brake” collision damage reduction system uses a high-precision millimetre-wave radar to measure distance from the vehicle in front and relative speed, and automatically control following distance. A computer determines risk of collision with the vehicle in front and urges driver caution by sounding an alarm and activating the warning brake. If the driver does not take action and the system determines a high risk of collision, computer control automatically activates the brake to reduce speed and limit collision damage.
b) More models fitted with Electronic Brake System (EBS)

All vehicles equipped with ESCOT-V are now fitted with EBS as standard equipment. As well as shortening braking distance and improving brake feel, EBS reduces jackknifing and extends tire life.

EBS enables electronic brake control by adding electronic signals to conventional braking systems, enhancing brake response and feeling. EBS incorporates anti-lock braking (ABS) and anti-spin regulation (ASR) systems.
