Common Causes and Symptoms of Piston Ring Failures

The diesel engine is a compression-ignition engine named after Rudolf Diesel, who invented the first diesel-powered car. Diesel engines have a reciprocating motion and convert diesel energy into mechanical power. The mechanical compression of the exhaust gases in the cylinder causes an elevated temperature in the air cylinder, which ignites the fuel. Because of their productive emergence, diesel engines are now considered a leading piece of machinery across many industries. Consequently, diesel engines are preferred in transportation as they have a longer life span and are perfect for heavy-duty tasks. 

What is a Piston Ring?

Pistons are essential components of internal combustion engines. It is surrounded by different metal rings called piston rings. Piston rings help your engine compress a mixture of air with diesel fuel and ensure that your engine is working correctly. Apart from that, piston rings maintain a consistent temperature throughout the combustion process to prevent excessive wear and friction. 

Furthermore, the top piston ring, known as the compression ring, is essential for maximum power output and fuel efficiency. It aims to seal the interior of the combustion chamber and sustain its airtightness. A wiper ring can stop excess gas from penetrating the engine and damaging its other parts. Nevertheless, each ring has its function, and as an owner, it is vital to ensure that your engine is operating at its maximum diesel power performance.

Symptoms of a Failing Piston Ring

Indeed, diesel engines are going through lots of heavy workloads. Your engine, as well as its parts, is highly prone to damage and malfunctioning. The piston ring is the most affected part of a poor diesel engine. Thus, it would be best to determine the signs that your piston ring is worsening.

The most common symptom of a failing piston ring is excessive oil consumption. A poor piston ring will increase the oil consumption of your truck. When the cylinders are working at their maximum capacity, the rings will wear, which means the oil will leak into the combustion chamber. Experts recommend checking your engine’s oil regularly. This will ensure that your vehicle runs smoothly without additional problems. If you notice any of these symptoms, you should consult a mechanic immediately. Other symptoms of a failing piston ring include poor acceleration, loss of power, poor performance, and changes in exhaust smoke.
