Why does my Cummins exhaust have white smoke?
Why does my Cummins exhaust have white smoke?
Published on Jan 24, 2017. White smoke is caused by either unburned fuel or coolant. On the common rail Cummins, white smoke is more characteristic of an injector problem. If the exhaust smells almost like bug spray, it is unburned fuel. Injector and poor fuel problems can typically be cleared up by treating the truck with DIESEL EXTREME.
Why does my Cummins exhaust smell like bug spray?
On the common rail Cummins, white smoke is more characteristic of an injector problem. If the exhaust smells almost like bug spray, it is unburned fuel. Injector and poor fuel problems can typically be cleared up by treating the truck with DIESEL EXTREME. If the exhaust smells slightly sweet, it is coolant.
Is it possible for a fuel filter to produce white smoke?
Yes. If the fuel is contaminated with water or some other foreign material it is possible that it will produce white smoke. The best way to test the fuel is to pull the filter and put it in a clear glass. Wait a few minutes and see if there is any separation. Can air in fuel cause white smoke? Yes. This is another common cause of white smoke.
What are the problems with a Cummins 5.9 engine?
Despite the reliability of the Cummins 5.9, its fuel system is its Achilles heel. As discussed above, the fuel injectors are responsible for spraying highly pressurized fuel into the engines cylinders. With the 5.9’s fuel pumps flowing north of 25,000psi, the injectors face a significant amount of stress.
When did the Cummins 5.9L B series come out?
The Cummins 5.9L “B-Series” diesel engine was produced from 1984 up until 2007. First generation versions were named the 6BT but also commonly referred to as the 12v, or 12-valve. Each cylinder had 2 valves, hence the name 12-valve. Midway through 1998, the 6BT was replaced with the ISB, which stands for “Interact System B”.
Why do I get white smoke from my diesel engine?
White smoke occurs for one of three reasons 1. Raw diesel comes through the exhaust completely unburned 2. Water entering combustion chamber. 3. The temperature in the combustion chamber is too low. Now, let’s look at three scenarios. What is wrong really depends on the “type” of white smoke you have.
Is the Cummins 6.7L engine still in production?
The engine continued in production until 2007 when it was retired for the 6.7L Cummins, primarily due to increased emissions regulations. The Cummins diesel engine is unique in the diesel truck world, as it is uses an inline design and only features 6 cylinders.
What does white smoke mean on a Duramax engine?
White smoke from an LB7 Duramax engine often indicates faulty injectors. We’ve heard of rollin’ coal, but rollin’ snow? Not a good sign. Blowing white smoke is a red flag for your diesel engine, yet we see this happen all the time to our customers.
Why does my diesel engine have smoke coming from the exhaust?
Consistent smoke coming from the exhaust most likely indicates a deeper internal problem with the engine. A small puff of smoke during quick acceleration is acceptable with older diesel engines due to a lag before the turbocharger’s air flow can match the increased volume of diesel fuel injected into the cylinders.
Why is there white smoke coming out of my exhaust?
Usually, white smoke indicates that the diesel fuel is not burning correctly. Unburned diesel fuel will make its way through the exhaust completely unused. Be careful of white smoke as it will irritate your eyes and skin. If white smoke occurs during a startup in freezing temperatures, then goes away,…
What does white smoke from a diesel engine mean?

Why does my diesel engine smoke when I accelerate?

What causes black smoke coming from a diesel engine?
Black smoke is the most common smoke color coming from a diesel engine and most likely indicates something is wrong during the combustion of the diesel fuel. When diagnosing the problem the first place to look at is the mixture of air and fuel flow into the cylinders.
