What is a piston ring?
The piston ring is a split kind of ring that fits outside the piston inside the engine. The primary function of a piston ring is to seal the combustion chamber, support a heat transfer from the piston to the engine, and control the engine’s oil usage. As time goes by, the piston ring can usually break and will need to be changed. If this happens, a mechanic will typically have to be hired in order to deal with the issue.
Why do piston rings break?
If your engine misfires, you see smoke from the exhaust, there’s not enough accelerating power or you’re seeing too much oil consumption, then this might be an indication that your piston rings are broken. Extreme oil consumption, for instance, might be happening because of the sludge accumulation near the oil control rings. While some special cleaners can in some cases solve the issue by cleaning up the rings, this isn’t always the case.

When the piston rings fail, they cannot keep the oil from leaking into the cylinder; as soon as the oil leaks through, it will get mixed up in the combustion process. Slowly and gradually, all your engine oil will leak into the cylinder, and you will witness a drop in your car’s engine oil level.
What causes a piston to lose power?
Weak Acceleration. When the piston rings get damaged, the engine’s combustion chamber loses pressure. This causes the engine to lose power since the piston cannot completely compress the fuel and air mixture. As a result, the engine creates less power in each cycle.
What is the purpose of piston rings?
The piston rings help keep the combustion chamber known as the area inside each cylinder – pressurized, which makes it easy for combustion to happen. The piston rings are the seal between the piston and the cylinder walls to keep the combustion chamber’s pressure and oil in the crankcase.
