Here’s how it works.
Together with an enhanced exhaust gas recirculation (EGR) system and variable-geometry turbocharger, SCR technology allows all Isuzu N-Series trucks to meet the demanding emissions standards.
This revised exhaust system also monitors the DPF’s particulate status and the level of DEF required for the SCR system to operate, and reports the results to the driver through the Multi-Information Display.
Under normal highway operating conditions, the DPF will regenerate itself automatically to remove particulate matter from the exhaust. But under slow-speed, stop-and-go or long-idle conditions, the system may require—and will allow—the driver to manually initiate a DPF regeneration cycle manually.
It stores 7.4 gallons of diesel exhaust fluid, and is even equipped with a heating element to ensure reliable operation in cold-climate conditions.
DEF consumption is only 1% of fuel used, so the DEF tank should be refilled every 20-25 times the fuel tank is refilled.
