If the driver slows or stops the truck, the regen will stop. Should be close enough. Extreme heat causes the oil to burn, oxidize and create layers of sludge and deposits. The KTS will bring up the next screen with particulate filter status, Engine speed, exhaust gas tempreatures and differential pressures. “With the accuracy in modern computerization, and the rigs that control that whole system, it’s something you want to pay attention to and address relatively soon, before you enter ‘limp mode’ or ‘De-rate’ where the truck will not operate over 20 to 30 mph in some cases.”, If the EGR system is failing, with improper recirculation of the exhaust, the truck runs with a lot more particulate and a lot more soot, therefore also clogging the DPF even more. To those having trouble, what Ive read it seems that the Isuzus are set up to do a regen when the DPF reaches 70% blocked, whereas the Hinos are set up to regen at only 30%, so that if you delay a regen in an Isuzu, the DPF becomes critically blocked and the truck goes into limp home mode. Possible causes – Check coolant level – Check fuel quality – Faulty Upstream Exhaust Temperature – Upstream Exhaust Temperature harness is open or shorted I'm by no means an expert. As I said above, it will sit at "200-regen start" forever, then sometime it will start the regen (370-regen active) then a couple times WHILE IN REGEN ACTIVE, will kick out into regen start. Once the exhaust temperature reaches a certain point, for example while driving at high speeds, the built up matter in the DPF turns to ash. The next step is to select DPFE regeneration adpatation.

To those having trouble, what Ive read it seems that the Isuzus are set up to do a regen when the DPF reaches 70% blocked, whereas the Hinos are set up to regen at only 30%, so that if you delay a regen in an Isuzu, the DPF becomes critically blocked and the truck goes into limp home mode. This reduces the soot burn temperature to 350-400C…a temperature readily reached by engines under even light loads. I have Chang the EGR Valve same problem. As a result, we distributed a query to members of the World Sweeping Association. Switching your medium-duty truck into DPF Regen mode allows the DPF to burn off the soot and ash, resulting in a cleaner running filter. Nothing happens.

Continuously regenerating filters operate at a balance temperature, which can be determined through a laboratory … Fuels with higher cetane burn more efficiently and completely than those with lower cetane ratings. If anyone out there is an Isuzu tech and has training info they would share with me it would be appreciated. The tighter seals provide improved combustion efficiency, thereby translating to not only better fuel economy, power and a better running engine, but also the efficiency required in the combustion cycle to prevent blow-by and added particulates flowing through the exhaust system. Passive DPF regeneration systems are very similar to active DPF regeneration systems but they typically require some type of manual input. Isuzu 2011 NQR 450 290 000 Km.
