What causes a Cummins ISX to lose power?
What causes a Cummins ISX to lose power?
Hazy fuel is indicative of water emulsified in the fuel. In general, dark hazy fuel will not damage your engine. It indicates however, poor fuel quality, which will definitely not provide you with peak engine performance. So what else could be causing the egr and turbo to fail.
How does the Cummins Engine ISX 450 hp compare to Caterpillar engine?
I asked how the ISX 450 hp Cummins engine with Eaton automatic transmission compares to the Caterpillar engine. He did not know the answer. I would just like to know if the ISX 450 hp Cummins is efficient, and has good mpg.
Are there any problems with a Cummins Engine?
We have an ISX of that vintage and it’s alot of problems. it depends on if the cummins is one of the EGR motors. the EGR is a huge headache on the cummins engines. other than that, the ISX is for the most part, bulletproof. very strong engines. they are even better when they are not castrated.
What kind of camshafts does a Cummins ISX have?
Dual overhead camshafts: If your ISX was manufactured before 2010, it has a dual camshaft system. The first cam creates high-pressure fuel injection for clean power while the second has a set of lobes to operate the integrated engine brake. The second set of camshafts also moves the intake and exhaust valves.

How to tell if you have a problem with your exhaust manifold?
1 Excessively noisy engine One of the first symptoms of a problem with an exhaust manifold gasket is an excessively noisy engine. 2 Decrease in power, acceleration, and fuel efficiency Engine performance issues are another common symptom of a problem with an exhaust manifold gasket. 3 Burning smell coming from the engine bay
Why do I have soot coming out of my exhaust?
Failed, intermittent, improperly installed, incorrectly wired or loose Exhaust Gas Temperature sensors may cause inaccuracies in the soot model. Look at all temperature sensors when the vehicle is cold to verify that they read close to each other. Improperly routed differential pressure lines.
What causes an exhaust gas sensor to fail?
Extreme heat is often a cause of failure over time. Lucas say a common problem with all wired sensors is that wires can break, especially if subjected to harsh twists and turns. They are also easily damaged when replacing other components in the exhaust system.
What happens to NOx when exhaust pressure is increased?
Increased exhaust pressure may also prevent some exhaust gases from leaving the cylinder (especially in naturally aspirated engines), creating an internal exhaust gas recirculation (EGR) responsible for some NOx reduction. Slight NOx reductions reported with some DPF systems, usually limited to 2-3% percent, are possibly explained by this effect.
Why does my Cummins ISX low boost high exhaust temps?
If you run down south for the week, truck will no due this all week come north and it will do this all the time. 35 degrees or less and it does it. Changed out Exhaust gas pressure sensor, did not fix. Any ideas? check the turbo see if the shaft rocks enough to hit the housing also check the boost sensor see if its plugging up
What does the ISX stand for in diesel engine?
It upheld its name because it had an innovative fuel system called the “Interact System.” The “IS” in ISX stands for “Interact System.” Since its launch, the ISX has been the core of Cummins’ diesel engine fleet. Not only has it advanced with quicker processing, but it has also increased fuel efficiency since its debut.
Why does my ISX low boost have soot in it?
The soot can build up in the moving parts and the actuator can’t move it properly. In the 2nd video, you can see the turbine housing. The vanes on the turbine wheel fit in the slots of the rotating collar in the turbine housing at the left. If those slots fill with soot, the that collar can stick as well.
What does the engine management warning light mean?
The engine management warning light is different from the other lights on your dashboard, as it doesn’t alert you to a specific fault. Unlike the coolant temperature warning or low oil level warning lights, the engine management light (EML) can be triggered for a number of reasons.
Do you need an engine warning light to pass Mot?
The answer to this is ‘no’ – the light itself isn’t but the issue that causes could prevent your car passing its MoT depending on what it is. Unlike many of a dashboard’s other warning lights, an engine warning light doesn’t alert you to a specific fault.
Is it possible to reset an engine warning light?
While the documentation for some older cars provided instructions on how to check and reset engine warning lights, it’s not usually possible now cars have grown more sophisticated. It’s well worth paying for accurate diagnosis, though, so a proper and effective repair can be made.
What’s the boost pressure on an ISX 15?
I have an isx 15 Cummins with low boost pressure about 20 psi. I checked turbo and it is ok. Checked for leaks in cache I have an isx 15 Cummins with low boost pressure about 20… I have a cummins isx 15 2350 in a kenworth t680. The boost I have a cummins isx 15 2350 in a kenworth t680. The boost is goin up and down at idle and goin down the road.
