Causes of cylinder-bore wear

Do you know that each detail of the car has its own service life? The maintenance scheme, its volume, and frequency are predetermined in the Maintenance Schedule issued for every car. Observance of the Maintenance Schedule will help the car to stay running longer. It needs to note that these measures are not very expensive which cannot be said about engine repair.

Of course, engine wear and tear is inevitable but the right maintenance in time maximizes the life and performance of an engine.

What causes cylinder-bore wear and how to slow it down?

Causes of cylinder-bore wear – is the theme of our article. There are three main types of cylinder-bore wear:

  • Abrasion;
  • Erosion;
  • Corrosion.

One of the causes of rapid wear of the cylinders is inefficient lubrication. The film lubricant shall always separate the cylinders and pistons so it is very important care should be taken that the efficiency of the oil is not reduced in service.

The ingress of abrasives and other foreign particles into the engine has a great influence on the wear of the engine cylinders. Air purifiers help to reduce their impact separating the dust from the atmosphere.

In process of operating the motor oil efficiency is reduced. Motor oil loses its original properties and becomes contaminated over time.  And it will be good advice to change the motor oil in time and control the oil level in the engine.

The speed of cylinders wearing depends on the material used by the pistons producing. The softer the pistons the more rapidly the cylinders become wear away. It can be explained that any particles of dust which mix with the ‘oil film are liable to become embedded in a soft piston and wear off the cylinder surface as the piston up and down moving.

A slightly bent connecting rod can cause wear to the cylinder because the piston forces against one side of the cylinder.

The ovality and cone shape of the cylinders is eliminated by boring the cylinder on the machine, provided that after boring the diameter of the cylinder does not exceed 2% of its nominal size, and the reduction in wall thickness does not exceed 1/12 of the original thickness.
