It is Cummins opinion that the max EGT’s, whatever they may be, of the stock motors are safe for extended intervals. There are a more things to conside than just the EGT’s. Initial injection timing, dynamic inection timing, injection event timing, valve overlap, etc, all play to what we see as a final EGT.
What EGTs are safe 6.7 Cummins?
the DPF, when in regen, will kick the EGT’s over 1400 degrees so i would say 1550-1600 would probably be the MAX safe temp… if you hit 1500 degrees then you just more than likely cracked your DPF. If you start seeing 1300 degrees, even during regen, then you might be seeing an engine problem.
What is the maximum EGT Diesel?
The absolute maximum safe EGT range is debatable. Our universal rule of thumb, regardless of engine make/model/year, is to not exceed 1250° F and not to operate in the 1200° F – 1250° F range for an extended period of time.
What EGT is too high?
For towing, we’d say a sustained 1,200 to 1,300 degrees is a safe number, with occasional spikes of up to 1,500 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.
What’s a safe EGT Cummins?
Any EGT under 1300* is safe. The Cummins has been proven to run all day at that exhaust temp with short bursts above but I choose not to keep my EGT’s sustained that hot for long periods. When pulling, I try to keep it under 1200* but there’s others who will say otherwise.
What is ext temp gauge?
The exhaust gas temperature (EGT) pyrometer can be one of the most important gauges on a turbo-diesel-powered vehicle. … A pyrometer is a temperature gauge designed to measure high temperatures above those measurable with an ordinary thermometer.
How hot is too hot for a diesel engine?
You can run up to 220°F all day long without any problems. The fluid will last a long, long time at that temperature. You can run up to 250°F for up to a half hour at a time. Above 250°F you should find a safe place to stop and idle or fast idle in park or neutral to cool the trans.
How do I lower my diesel EGT?
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. Exhaust gas temperature is a funny thing.
What is normal 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.
Will a bigger turbo lower EGTs?
A properly sized turbo will effectively lower egts all around… To big and you will notice higher egt’s until boost comes in and too small you will see high egt’s in the top end… A intercooler can help but no where near a properly sized turbo would.
Does an intercooler lower EGT?
While all intercoolers will lower intake air temperature and EGT, some aftermarket units will actually block flow-through to the heat exchangers behind them (namely the radiator). Trust us, achieving cooler EGT by increasing coolant temperature is not a fair trade.
What does EGT mean on a diesel?
A. EGT stands for exhaust gas temperature, and is the single most important indicator of how a diesel engine is performing. Unlike a gasoline motor, a diesel motor will continue to make power as more fuel is added. As more fuel is added, heat will be generated until the motor just gets too hot and things start to melt.
Will a bigger exhaust lower EGT?
It lowers EGT’s because it allows the turbo to breathe better which helps get more of the exhaust gasses out. It’s better flowing. It’s important to keep egt’s cool cause if you don’t then you run the risk of melting a piston and damaging the motor.
How hot does a diesel turbo get?
They can get to 2000 deg F if you have too much fuel and not enough air. My little diesel project with a turned up injection pump and HY35 can get up to 1200 when going up hills.
Why is my exhaust temperature high?
Fouling of the turbine side of the turbocharger is a common cause for high exhaust gas temperatures. The sequence of events is often as follows: → Fouling of turbine (coke deposit) → Bad turbocharger performance → Lower airflow and charge air pressure → Higher exhaust gas temperatures.
