1. The new car needs to undergo good running in

Although the surface of the cylinder block is very bright when produced by the manufacturer, it is still uneven from a microscopic perspective, and the raised parts are easily damaged. If subjected to a large load at this time, it will cause strain on the surface of the cylinder block. So in the use of a new car, it is necessary to have a light load. After the protruding parts are ground flat, the surface of the cylinder block can withstand a large load. In this way, the service life of the surface of the cylinder block will be extended, and a well worn cylinder block has a much longer relative life than an unburned cylinder block.

2. The air entering the cylinder block should be clean

If the air entering the cylinder block from the air filter contains a lot of dust, it will quickly increase back to the surface of the cylinder block like abrasive wear, so it is necessary to make the air entering the cylinder block very clean. In order to improve the filtering effect, a layer of foam sponge can be added outside the paper core. The foam sponge must be washed with water every day to avoid blocking.

3. The surface of the cylinder body should have good lubrication

Body friction causes less wear than dry friction. To avoid dry friction, the cylinder body and piston surface of the lubricating oil should be well adhered to form liquid friction. This requires the lubricating oil to have an appropriate viscosity. The viscosity of lubricating oil is related to temperature, and lubricants with different viscosities should be used in different seasons.

4. The engine should have good flexibility in operation

The main reason for engine detonation is due to excessive combustion speed. The waterfall vibration causes excessive impact force on the piston, causing wear and tear by knocking on the cylinder wall. If the driver fails to shift gears in a timely manner and stalls, sudden refueling will cause a knocking sound in the cylinder block. In this case, it is necessary to shift to a lower gear and accelerate again in a timely manner, otherwise the surface of the cylinder block may be damaged by knocking.

5. Avoid cylinder sticking phenomenon

The phenomenon of cylinder sticking refers to the blocky adhesion between the piston and the surface of the cylinder block. The main reason for cylinder sticking is not only the lack of lubricating oil in the engine, but also the overheating caused by poor engine cooling, which causes the lubricating oil to lose its lubricating effect

6. Avoid cold vehicle use

When driving in winter, the lubricating oil is in a solidified state and cannot provide lubrication. At this point, preheating must be carried out. The method of preheating is to let the engine run at idle for more time, and wait until the temperature rises and the lubricating oil has started before starting the vehicle.

7. Avoid carbon deposits falling into the cylinder body

There is a lot of carbon buildup in the piston crown and cylinder head, which can cause scratches and wear on the surface of the cylinder block when it falls into the cylinder body. To reduce the generation of carbon deposits, it is necessary to use specialized engine oil. Car owners should also promptly clean the carbon deposits on the top of the piston in the cylinder head. When there is too much carbon accumulation, it will make the combustion chamber smaller, increase the compression ratio, and cause detonation.
