EGT is an indication of how hot the combustion process is in the cylinders, and the amount of “afterburning” that is occurring in the exhaust manifold. EGT is also directly related to the air/fuel ratio. The richer the air/fuel ratio in a diesel, the higher the EGT will be.

How do you reduce the temperature of exhaust gas?
The reduction occurs by reintroducing in the engine cylinders of a part of the exhaust gases. Thus, the amount of molecular oxygen in the cylinders reduces, which, by changing the combustion rate of the fuel, reduces the temperature per cycle.
What temperature should diesel exhaust?
The diesel oxidizing catalyst (DOC), similar to a catalytic converter in gasoline engines, requires at least 662 °F to function. An exhaust cooler reduces the temperature of the exhaust gas before it exits the tailpipe.

What happens if exhaust gas temperature is too hot?
Why is EGT important? Because if your in-cylinder temperatures get too hot, you can melt pistons, crack heads, destroy turbos, and create general havoc within your engine. A diesel needs a certain amount of heat to run, but high EGT should definitely be avoided.
Does more boost lower EGT?
It's not necessarily true that adding boost will lower EGTs in a normal optimal combustion scenario... But, if you are experiencing an overfuel condition (such as caused by a chip/programmer), it causes higher EGTs due to fuel burning past the cylinder, causing high exhaust temps... if you add more air (via increased ...
What affects exhaust temp?
Every exhaust system features a different design and pipe diameter. The length and width of these pipes affect how cool or hot the exhaust gets. The further the exhaust gases need to travel, the more heat becomes lost in the process.

What is a good EGT temp for a diesel?
It's just too much to ask a diesel to run at those types of temperatures. For towing, we'd say 1,200 degrees is a safe number, with occasional spikes of up to 1,400 degrees when climbing grades being an acceptable risk.
What should my exhaust temperature be?
The average temperature range for the exhaust system is between 600 to 930 Fahrenheit. Driving for a longer period or driving the car harder can cause temperatures to rise to 1600 to 1800 Fahrenheit as well. The exhaust system is made up of many parts.
Egt And Some Information You May Not Have Been Told Before
What causes increased EGT?
As we pointed out earlier, high EGTs are the result of too much fuel for the available air. If you see EGTs climbing over 1300º F., the fastest way to reduce the amount of fuel going to the engine is to back off the accelerator pedal. Another possible solution is to downshift if your speed permits it.
What does high exhaust temp mean?
When a Diesel Particulate Filter regeneration process begins, the High Exhaust System Temperature HEST lamp illuminates and exhaust gas temperature may reach 1500 degrees F. That's hot enough to ignite and/or melt materials and burn people.
