The exhaust pipe muffler temperature is usually between 300 to 500 degrees , but they are also known to handle higher temperatures of up to 1200 degrees. Extreme exhaust temperatures can destroy the catalytic converter.
How hot does a typical exhaust system get?
The average temperature of an exhaust pipe is between 400 and 500 degrees . Depending on how long you are driving. The temperature can be as low as 300 degrees or as high as 1000 degrees. The heat from the engine is removed by the exhaust system and muffler.
What is the average temperature of an exhaust manifold?
A diesel engine's exhaust manifold EGTs will typically run at about 300 to 500 degrees under no-load to part-throttle conditions, 800 to 900 degrees under a medium load and 1,000 to 1,200 degrees under a really heavy load and under full throttle.
What is a good EGT temp?
The temperature of the turbine, (turbo) blades probably never reached above 1000 degrees. A good safe target is to set your edge, or if you have regular gauges, your foot, at a cutoff temperature of 1250 . Then you are never going to get your temps above an “sustained” unsafe limit.
Is diesel exhaust hotter than gas exhaust?
Gasoline engine exhaust runs hotter than diesel exhaust (less efficient so more heat lost), but they run hotter under load than they do at idle.
How hot is too hot for EGTs?
How Hot Is Too Hot for EGT's? 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 should EGT be at idle?
The longer it idles the cooler it will get, but no cooler than around 250* if the engine is at full operating temperature unless its VERY cold outside. When the weather is warmer summer then typically EGT's will stay more around 300-325* depending on how long its been idling.
Does more boost lower EGT?
lowering fuel and increasing boost would get your egts down . Your essentially adding more air. But as you know when you increase your boost your compressed air temp increases.
Is it bad to idle a diesel?
Most engine manufacturers recommend that newer diesel engines idle for no more than 3 minutes before driving . ... Letting an engine idle actually does more damage to the engine than starting and stopping. Running an engine at idle causes twice the wear on internal parts com- pared to driving at highway speeds.
What runs hotter diesel or gas?
In contrast, the heavy molecular structure of diesel fuel requires more heat to trigger combustion within the engine chamber. As a result, the exhaust temperatures emitted are particularly higher than gasoline, ranging from 1,000 to 1,200 degrees Fahrenheit.
What temperature is 7.3 EGT?
I just installed my egt gauge and I fell like its not reading right. At idle it's always around 200 degrees, at 65-70 it's around 600 degrees .
What is the highest recommended pyrometer temperature?
It depends on where the pyrometer is sensing. If you install pre-turbo then your safe point is a maximum of 1200 F or so , (it doesn't vary between engines much as it's based on the melting point of the aluminum pistons).
What temperature do Pistons melt?
You can melt a Piston at less than 1200 degrees EGT's , or you can run for hours with no ill effects.
What is a safe EGT for a 5.9 Cummins?
The optimal safe “sustained” EGT is no more than 1250* . Short bursts a little over that temp is OK but for no more than seconds.
How do I lower my EGT temperature?
How Hot Is Too Hot for EGT's? 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.
