What do you do if you have a high exhaust temperature?
High exhaust gas temperatures are caused by too much fuel and too little air within the diesel motor’s cylinders. Facilitate the efficient consumption of fuel, and lowered exhaust temperatures, by allowing more clean air to flow into the motor and reset the appropriate air to fuel ratios.
What does high exhaust temp mean on a Peterbilt?
The High Exhaust System Temperature (HEST) Lamp illuminates to indicate that high exhaust temperatures may exist due to aftertreatment regeneration. When this lamp is illuminated, ensure that the exhaust pipe outlet is not directed at any surface or material that will melt, burn, or explode.
Why does my Cummins ISX low boost high exhaust temps?
If you run down south for the week, truck will no due this all week come north and it will do this all the time. 35 degrees or less and it does it. Changed out Exhaust gas pressure sensor, did not fix. Any ideas? check the turbo see if the shaft rocks enough to hit the housing also check the boost sensor see if its plugging up
What’s the exhaust temp on a 2006 Cummins?
I have a 2006 ISX cummins 530 hp with 433,000 miles on it. It is an EGR motor. Problem is lately since weather has started to cool up motor will sometimes loss boost of about 10 lbs and exhaust temp will climb to 1000 to 1100 degrees. You might drive 5 miles and it comes out of it.
When did the Cummins ISX diesel engine come out?
Since its launch, the ISX has been the core of Cummins’ diesel engine fleet. Not only has it advanced with quicker processing, but it has also increased fuel efficiency since its debut. In 2002, the ISX became one of the first diesel engines to incorporate an exhaust gas recirculation (EGR) cooler system.
What kind of SCR does Cummins ISX cummings use?
The ventilated exhaust lowers the combustion chamber temperature. The ISX Cummings started featuring the selective catalytic reduction (SCR) system in 2006. It injects urea, which is an active element in diesel exhaust fluid (DEF), into the exhaust.
