Common Causes And Symptoms Of Piston Ring Failures

The invention of diesel engines in the 1800s was a significant breakthrough in machinery manufacturing that we still use today. It is now used in machinery, manufacturing, agriculture, transportation, and other uses.


Because it has a higher fuel economy than gasoline, it is a huge help to these industries. Diesel engines require regular maintenance to ensure diesel power performance for long-term, heavy-duty uses like towing and long-distance travel. The piston rings are an essential part of a diesel engine.


Uses of Piston Rings

Piston rings are a part of the diesel piston system. They make the engine run smoothly. The compression ring seals the combustion chamber. It prevents fuel consumption and gas leakage. The second ring, the wiper ring, will prevent exhaust gas from getting into other piston parts. The last ring is the oil control, ensuring that the chamber walls are oil-free.


Piston Ring Failures

Piston rings undergo enormous pressure to ensure that the engine functions well. Here are some possible failures of piston rings.


Inaccurate Assemblies

A poorly assembled piston ring will fail to perform its intended function as with any equipment. Poor compression and poor installation are two reasons why piston rings fail to form correctly. You can see the damaged side of the call if you want to check it.


Oil Control Ring

If there is an unusual or appreciable amount of oil consumption within the oil control rings, you can expect damage; this is often due to damaged or low-quality rings.



It is usual for fuel contamination to be caused by soil quality and dirt particles. Regular maintenance is essential for car owners. Piston rings can wear down from continuous use.

Inadequate filtering can cause dirt to combine with gas, interrupting the combustion chamber decreasing the rings’ lifespan.

Knowing more about piston rings can help car owners better care for their diesel engines. Let this infographic by Pure Power Diesel help you learn more.
