「
delivering maximum torque per unit of displacement in a
more compact, lightweight body. By combing the three
technologies of combustion optimization, exhaust gas
after-treatment, and electronic control, D-CORE diesel
engines deliver both excellent environmental and economic
performance.
Tie-up with Toyota in small diesel engines
In August 2007, Isuzu and Toyota Motor Corporation
agreed to work together to develop, manufacture, and
supply small diesel engines.
This collaborative development effort seeks to harness
both partners’ technical capabilities and expertise to
develop and manufacture the world’s highest-performing
diesel engine, a 1.6-liter class aluminum cylinder block unit
that will power Toyota models sold in the European market.
Production is planned to start in 2012.
Joint development projects with Hino Motors Ltd.
In August 2007, Isuzu and Hino Motors Ltd. agreed to
jointly develop engine emissions after-treatment systems
and cabins for heavy-duty trucks. By taking advantage of
their respective advanced technologies to efficiently utilize
development resources, both companies are aiming to
reduce the cost burden associated with complying with
increasingly stringent national environmental regulatory
regimes, ultimately enabling them to provide better
products to customers.
In addition to collaborating in the manufacture of
buses through J-Bus Co., Ltd., a company in which each
partner owns a 50 percent stake, Isuzu and Hino are
working together on the supply of truck components.
Developing alternative fuel vehicles
Isuzu is actively developing environmentally friendly alter-
native fuel vehicles based on the technology used in its
DE vehicles. Compressed natural gas (CNG) vehicles which
use natural gas as a fuel are extremely clean, with almost
no particulate matter (PM) and low CO2. Thanks to the
development of engines with multi-point injection (MPI),
a state-of-the-art fuel injection system, we are now able to
deliver both exceptional fuel efficiency and clean exhaust
gas performance.
We have also developed a diesel hybrid vehicle featuring
a proprietary hybrid system based on our D-CORE series of
DEs. By using a PTO-type parallel drive system and lithium-
ion batteries with an exceptionally long service life, we were
able to create an alternative fuel vehicle that combines the
reliability and economy required of CVs with environmental
performance.
