What temp is too high for EGT?
How Hot Is Too Hot for EGTs? Based on our own experience in the sled pulling and drag racing world, we can definitely say that any engine running at 1,800 to 2,000 degrees EGT for more than a second or two should be rebuilt every season and may incur turbocharger, cylinder head, or piston damage during the season.
What happens if exhaust temperature is too high?
With an internal combustion engine (gas or diesel), the EGT will rise as the engine makes more power or as the air/fuel mixture leans out. In the case of a lean condition within the engine, an EGT that is too high can lead to major detonation and cause severe engine damage.
What causes EGT to go up?
As diesel engines run hotter, their efficiency decreases because more fuel is needed to produce power. High EGT readings can be caused by a number of problems, including over-fueling, overheating, or blocked air intake filters or ducting.
What does an EGT do?
In a piston engine, EGT is a measurement of the temperature of the exhaust gases at the exhaust manifold. As the temperature of the exhaust gas varies with the ratio of fuel to air entering the cylinders, it can be used as a basis for regulating the fuel/air mixture entering the engine.
What is the maximum exhaust temperature of a diesel engine?
Diesel engine exhaust gases vary with speed and load. High loads and high speeds result in the highest temperatures. Generally, temperatures of 500700C (9321293F) are produced in the exhaust gases from diesel-cycle engines at 100% load to 200300C (392572F) with no load.
What happens with high EGT in a diesel?
In simple terms, high EGTs are a result of a rich running condition in your diesel engine. This means that the engine is burning too much fuel relative to the amount of air it is getting. You may notice the effects of this as black smoke coming from your tailpipe.
How much EGT is too much?
Best DPI setting You do want to avoid playing at too high of a DPI, anything past 12000 is likely excessive, but more importantly, some sensors at this DPI accelerate and emulate the dots per inch, causing inconsistencies, its not a true raw DPI.
What happens with high EGT?
Excessive EGT can also erode or crack the turbine housing. In extreme cases, high EGT can drive the turbocharger into an overspeed condition that exceeds the designed operating speed due to the additional heat energy. When this happens, either the turbine wheel or the compressor wheel may burst.

What happens if exhaust gas temperature is too hot?
Therefore, the exhaust gas temperature should be controlled below 135℃. If the exhaust gas temperature is too high, the lubricating oil may be carbonized and deteriorated and the lubricating performance will be reduced.
