Diesel Engine Water In Fuel Symptoms

Just like the symptoms of the common cold include congestion fever sore throat and headaches your engine experiences symptoms when it has water injected into it.

Diesel engine water in fuel symptoms. Since diesel fuel injection systems were first invented and used to control engine operation water in the diesel fuel has been the biggest contributor to the failure of such systems. But it s important to know the warning signs of water in your diesel fuel. Diesel is lighter than water so if there is water in the fuel it will settle to the bottom of the jar. This leads to galling premature wear damaged injection tips and further corrosion of sensitive fuel system mechanical components.

There are two main classes of chemical reactions that do this. Finally any water that makes its way through to the fuel injectors reduces the lubrication properties of the diesel fuel along the way. Water in fuel can come from a variety of sources. The initial symptoms of fouled diesel fuel include.

Here are seven must knows on diesel water plus the symptoms of water in diesel fuel that can save you headaches. Other sources might be harder to detect like a tank vent improperly placed by the boatbuilder. The symptoms of such failures within an injection system may include the following. Some of these might be obvious like a broken o ring on a deck fill cap.

Because the water is tricking the sensors that pick up the air fuel mixture like the o2 maf and intake air temperature sensor the air fuel mixture will jump up and down and cause rough acceleration. Look to see if there is a thin black line between the water and the diesel. Repairs are generally expensive due to the hi tech nature of components and the amount of parts that can be affected by the contamination. If there is microorganisms have started to grow which means you will need to add a biocide.

Low power from the engine reduced engine rpm increased fuel consumption poor cycle times or low speed smoke lower gear selection noise poor starting poor idle. Water in diesel fuel can wreck fuel quality when you store diesel fuel it undergoes chemical reactions which may turn the diesel fuel quality south.
