Common Causes And Symptoms Of Piston Ring Failures

Diesel engines have been one of the leading machinery pieces used across different industries globally since their invention in the late 1800s. From labor-intensive sectors like manufacturing and agriculture to the transportation industry, diesel engines are now an essential part of the world’s vehicle innovations.

Diesel engines are more durable than gasoline, ensuring a longer life span and giving drivers better fuel economy, especially truck owners. Most vehicles with diesel power performance are designed for heavy-duty tasks; hence, maintaining good engine shape and condition is a must to keep the power performance up. And among all crucial parts of a diesel engine, the piston rings are one of the things a driver must keep an eye on the most.

Defination of piston ring?

A diesel engine comprises multiple piston rings that work in different functions to keep the engine running. The first ring, known as the compression ring, completely seals the inside of the combustion chamber and maintains airtightness. The other function of the piston rings is controlling the oil that passes through the cylinder walls.

Common reasons of failures in piston rings

Another reason why drivers and truck owners should keep an eye on their engine’s piston rings is because these parts can be easily damaged, especially in the long run of vehicle usage. Here are some common causes of piston ring failures you should take note of:

1. Inaccurate Assembly – poorly assembling process of piston rings or inadequate compression. This sign can be noticed through an upward bend or broken ringside.
2. Damage in Oil Control Ring – some piston rings deteriorate after consuming an unusual oil amount during its function.
3. Contamination – dirt, poor oil quality, and contaminated fuel may also lead piston rings to have a shorter lifespan than expected.

Problems of a failing piston ring

Knowing the common causes of failure in piston rings isn’t enough to prevent these scenarios from happening. It is best for vehicle and truck owners or drivers to know apparent and straightforward signs of piston ring failure to better care for their transportation machines.

1. Unnecessary High Oil Consumption – the standard time of adding oil in trucks is 3,000 to 5,000 miles. Thus, if you think you’re adding more oil to your engine more frequently than the average, that might signify a piston ring problem.
2. Excessive Exhaust Smoke – believe it or not, it is uncommon for diesel trucks to emit thick exhaust smoke. A problem in the piston ring system might be the root when it does.
3. Weak Truck Performance – if your truck loses its power, it’s time to check your piston rings, as extensive wear and tear of these parts will not allow the truck to accelerate and may result in poor vehicle performance.

Driving or having trucks or any vehicle with a diesel engine needs extra attention and maintenance as these piston rings are crucial to the diesel engine itself. If these rings fail to function correctly, a truck would most likely lose its power and fail to meet heavy-duty tasks.
