ISUZU professionalism leads to engines that comply with new long-term exhaust gas regulations. State-of-the-art environmental performance -- for society and the Earth.

ISUZU presents the synthesis of three key technologies.
I-CAS is integral to achieving new long-term exhaust gas regulations level.

ISUZU has combined three key technologies - combustion optimization, aftertreatment of emissions and electronic control - to raise the fundamental performance of our diesel engines, make them more fuel-efficient, reduce CO2 emissions and raise output. ISUZU Clean Air Solutions (I-CAS) are the basis for our professional approach to building state-of-the-art engines that meet new long-term emission goals and contribute to the quality of life and society.

Engine complying with new long-term exhaust gas regulations [reference exhibition]

ISUZU engines incorporate fundamental improvements to fulfill our mission.
First is optimization of combustion, which is achieved through adoption of a high-capacity cooled EGR system, VGS turbocharger, and the high-pressure, multiple fuel injection of the electronic common-rail system. Second is aftertreatment emission technology, which relies on a Diesel Particulate Defuser (DPD) using an original ceramic filter to dramatically reduce particulate matter. Finally there is comprehensive electronic control technology for precise overall engine control and optimal combustion in all driving conditions. This works to maintain high power output, lower fuel consumption and reduce engine noise as well as to reduce NOx and PM to new long-term standards.

Diesel Particulate Defuser (DPD)
Cutting-edge aftertreatment of emissions.
DPD is a regenerating after-treatment device that collects particulate matter emitted from the engine by means of a ceramic filter and efficiently burns PM using the precise fuel injection of the electronic control common-rail system and original ISUZU emission temperature control with emission throttles. ISUZU is meeting the new long-term emission control regulations and aggressively addressing development as one of the aftertreatment devices in conjunction with engines.
