The rest of the exhaust heat gets forced out of the engine during the exhaust stroke-and this heat is what we read with our EGT probe mounted in the exhaust manifold. The exhaust heat temperature that we read on our EGT gauge will theoretically always be less than the peak in-cylinder temperature.

An exhaust gas temperature gauge (EGT gauge) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ...

In the diesel segment, we measure the heat created by combustion in the form of exhaust gas temperature, or EGT for short.
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.
How hot is too hot?
We get this the time, and unfortunately, there's no easy answer.
When diesel fuel is sprayed into the combustion chamber, it is ignited by intake air that has been compressed and can reach more than 900 degrees Fahrenheit.
When the diesel ignites, it can create a flame front of more than 4,000 degrees Fahrenheit.
The superheated flame front heats the air around it and creates high cylinder pressures almost 3,000 psi in some cases and temperatures more than 2,000 degrees.
This pressure and temperature rise is what pushes the piston down, creating horsepower and torque.
One important thing to remember is that although fantastic four 46 process occurs very quickly in a diesel engine, the slow-burning properties of diesel fuel keep the fuel burning for up to 40 degrees of the crankshaft's rotation, also known as crank angle.
Having an efficient intercooler is source one of the best ways of lowering EGT.
Way back in March 2008, we did a simulated towing test on a '97 Dodge with an aftermarket intercooler made by BD Performance.
On our mildly modified truck, the intercooler upgrade was good for a whopping 250-degree EGT drop at the same engine load and speed.
Where Does Egt gauge Heat Come From?
During the engine's power stroke, energy from the fuel's combustion pushes the piston down.
But not all of the energy released from the fuel is converted into work.
The unused energy becomes heat, some of which is absorbed by the pistons, cylinder walls, and cylinder head s.
The rest of the exhaust heat gets forced out of the engine during the exhaust stroke-and this heat is what we read with our EGT probe mounted in the exhaust manifold.
The exhaust heat temperature that we read on our EGT gauge will theoretically always be less the peak in-cylinder temperature.
However, it is also possible that the exhaust gas temperature at the EGT probe will be more than the sustained in-cylinder temperature, especially if the engine has radical fuel tuning.
This false reading can be caused by excess fuel igniting in the exhaust manifold, which creates a secondary combustion event.
Either way, high exhaust gas temperatures put the engine, exhaust valves, and turbochargers under a tremendous amount of strain and can lead to component failure.
This is why we monitor EGT-to keep things from melting, cracking, and breaking.
Mahle makes a steel piston for the 5.
One such set was run at more than 2,000 degrees EGT in John Robinson's Funny Car engine pictured for two full seasons and came out perfect.
How Hot Is Too Hot?
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 egt gauge season and may incur turbocharger, cylinder head, or piston damage during the season.
It's just too much to ask a diesel to run at those egt gauge 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.
The concept of EGT is analogous to putting something in the oven.
You can put your hand in a hot oven for a second or two, and nothing will happen.
Leave it in there, and you'll get burned.
The same thing happens in a diesel engine.
The longer the engine spends at a high EGT, the more likely it is to become damaged.
One of the low-EGT kings of the diesel segment is Jeff Prince.
Prince's truck made approximately 1,300 hp but never saw more than 1,400 degrees on the pyrometer thanks to a wicked combination of compound turbos, water injection, intercooling, and nitrous.
How Do I Control EGT?
So you may be asking yourself, if high EGT is such a harmful thing, why doesn't everybody make their engine run between 1,200 and 1,400 degrees?
The simplest explanation is that it starts to get expensive to try and keep a powerful engine cooled down.
Adding fuel is the most common way of achieving more power in a diesel engine, and this excess fuel creates heat.
It can be controlled through a combination of larger turbochargers, aftermarket intercoolers, and water injection, but those parts can cost thousands of dollars.
For most people, it's easier to just buy a programmer or injectors and live with the high EGT levels.
However, living with superheated EGT levels isn't a solution-it's just putting off the problem.
Sooner or later the stress on the engine will start to show, so it's best to keep your EGT low, reduce exhaust drive pressure as much as possible, and go easy on the injection timing.
We have a self-imposed limit of 1,600 degrees while racing, and 1,200 degrees while towing.
Any higher than that, and we'll look to water injection, intercooling, nitrous, or using less throttle to cool things down.
Intake air temperatures entering the engine have a dramatic effect on EGT, which is why intercooling and water injection are commonly used to cure EGT problems.
In addition to lowering EGT, having cooler air entering the engine post turbocharger will increase horsepower as well.
Aftermarket cold-air intake systems such as the Banks Super-Scoop can reduce EGT and also add power.
Competition EGT: What the experts say Exhaust gas temperature is a funny thing.
We've seen engines hurt parts at 1,400 degrees, while others will live at 2,000 degrees.
In common-rail engines especially, EGT will only tell you part of the story.
Since it's very expensive to measure peak cylinder temperatures and pressures, we don't know exactly what's happening during the injection event.
A lot of timing and injector pulse width could create a very hot condition for the piston, but since most of the energy will be used up, the EGT reading may not be that high-even though we may be doing possible engine damage.
A stand-alone computer system in which all the injection parameters can be changed and modified would be learn more here big help in making tremendous amounts of safe power with the newer, high-pressure injection common-rail engines.
Erick Brown - Brown's Diesel 1,138hp no-nitrous common-rail Read article Competition EGT: What the experts say We have a lot of 2.
With a good intercooler, we're still able to keep the EGT less than 1,600 degrees during the pull.
There is really no reason to run any hotter than that-you'll just be harder on parts.
With high-pressure water injection, we can put our EGT level wherever we want.
We can take an 1,800hp Modified Class pulling engine that would see 3,000 degrees without water and reduce the EGT to 1,400 degrees.
Dan Scheid - Scheid Diesel Diesel competition engine builder While large turbochargers will flow more air and help reduce EGT, one can only go so large.
Here is a comparison between the 60mm compressor upgrade used on Project Rust Bucket, and the 95mm secondary turbo on Erick Brown's 4,000-rpm common-rail.
Most trucks would be hard-pressed to egt gauge spool a turbocharger this big.
We've spent a lot of time talking about high EGT, but what about low EGT?
Shutting a hot engine off can lead to oil burning, which leaves carbon deposits called coking behind.
Make sure your EGT gauge reads less than 400 degrees Fahrenheit before you click it off.
