|The 6th-generation ELF.|
Isuzu Motors has introduced the first model of its fully remodeled ELF truck—the sixth generation of the popular commercial vehicle. Automatic start-stop systems are now standard equipment in the non-hybrid ELF models—ELF is the first truck to implement this type of fuel-saving system as standard. Isuzu also offers a hybrid version of the ELF (earlier post).
The new ELF features a newly developed D-CORE 3.3-liter intercooler turbodiesel engine that offers better fuel efficiency and reduced emissions. D-CORE is Isuzu’s next-generation diesel engine series that features small displacement combined with supercharging to deliver better economic and environmental performance.
The engine in the new ELF has complied with Japan’s new long-term emissions regulations and cleared a fuel economy standard for heavy duty vehicles. The engine has also acquired a certification for 2005 low emission standard for heavy duty vehicles.
The new engine uses a Variable Geometry System (VGS) Turbo. The increased charging ratio from the VGS turbo, the high-pressure common rail injection, and the larger capacity cooled Exhaust Gas Recirculation (EGR) improve combustion, all under the management of Isuzu’s control software.
Japan’s long-term emissions regulations reduce acceptable PM emissions down to 0.027 g/kWh, a reduction of 85% from the new short-term regulation value of 0.18 g/kWh. NOx levels under the long-term regulations are 2.0 g/kWh, a reduction of more than 40% from 3.38 g/kWh.
Isuzu first introduced the ELF in 1959—since then, Isuzu has produced more than 5 million units of the various models. Today, the ELF is sold to more than 100 countries in the world and has the number 1 market share in Japan and other countries. The ELF is the best-selling low-cab-forward truck in the world, according to Isuzu.
