How do piston rings get worn out?

Piston rings are an indispensable rubbing element on which the service life of the engine depends. Excessive consumption of them affects the negative fuel consumption and is associated with the wear of the cylinder smoothness. As a result, the engine power decreases. So if you want to take care of your car and you know how much it costs to overhaul the engine, first of all take care of worn piston rings.

When does the engine take oil &#; how to fix it and what could be the reason?

Naturally, piston rings wear out by using the engine. Therefore, after a mileage of about km, it is worth deciding to measure the compression pressure, which will help determine the condition of the piston rings. The lower than the nominal compression pressure in the cylinders is caused by m. in wear of piston rings and cylinder smoothing in the engine.

If you notice that your engine is taking oil, the reason may be an underestimated compression pressure or a pressure difference between the cylinders (it should not be more than 0.2 MPa). Excessive oil consumption can be compensated for by choosing the Cerazamizer CS engine oil additive. It regenerates engine components and, more importantly, raises and equalizes compression pressures.

Other causes of piston ring wear related to engine condition

If the negligence occurs prematurely, it may be the result of inadequate running-in of the engine. The new car reaches the engine in the first km &#; up to km should not exceed 2/3 of the maximum revolutions and use full acceleration. Proper arrival of the engine increases its service life and allows you to save oil in the future.

Another reason for the destruction of piston rings is the use of inappropriate engine oil, improper selection of the oil filter. Piston rings have a sealing function and scrape excess oil from the cylinder walls, so as a result of using bad oil, the rings may seal, i.e. sealing them in the grooves with carbon deposits (unburned fuel and oil particles).

Technical disadvantages

Another example of faster destruction of piston rings, in addition to their burning and natural wear, are technical defects. The first reason for premature wear of the rings is the use of the wrong material in the manufacture of the rings, which in turn makes them not as resilient as they should be. An important role is also played by their unskillful execution and incorrect assembly. In the latter case, fluttering the ring in the piston groove excessively consumes the ring, which can even lead to its breakage.

Partial overhaul of the engine &#; cost

In addition to non-professional assembly, the quality of repair plays a big role in the wear of the rings. When it is fast and cheap, you can expect that it has not been done correctly. Usually, a partial renovation of the car, i.e. replacement, for example, of rings, costs over PLN 1,000 &#; usually the price oscillates around PLN 2,000.

Replacement of rings can be combined with the grinding of the cylinders, but it does not have to. The most important thing is that the rings fit snugly to the piston groove and can rotate in it &#; otherwise they will wear out quickly and will not provide sufficient sealing. Also make sure that the piston grooves are cleaned of carbon deposits.

Additives for engine oil &#; is it worth it?

You may be wondering what engine oil additives can help you in case of piston ring wear. &#;Locking&#; piston rings, as a rule, means that a visit to a mechanic is necessary. In such a situation, none of the additives will prove helpful, especially in the case of a very worn engine.

However, if you have just bought a car or have recently replaced the piston rings and do not want to repeat it anytime soon, the Ceramizer CS engine oil supplement can help you. By using it when the reason for taking oil is a slight wear of the rings, you can count on its effectiveness.

The way I think of piston ring, as the rim wears off, there is less and less pressure forcing the ring against the sides of the cylinder. When the rings start leaking oil, can you actually see some daylight between the edge of the ring and the wall of the cylinder? Or does the leakage start a long time before there is any visual evidence?
