Engine pollution is a rather interesting and important topic. Several main causes of its contamination can be distinguished - thermal oil decomposition, mechanical wear of coatings and the appearance of chemical insoluble compounds. On the walls, deposits are formed, which adversely affect the operation of the motor. At the same time, the incorrect selection of oil only exacerbates the situation. The standard example was poured low-grade oil that did not have enough detergent additives in its composition. This topic will be devoted to this article.

Dirty engine, reasons for pollution

There are a number of factors contributing to the Nagara formation:

1. Condensation of water vapor.
2. Realuning the fuel and air mixture.
3. Worn piston rings, through which gases periodically break through.
4. Violation of interservice intervals.
5. Short trips at minus temperatures.

How to save the engine how to prevent engine contamination

It is impossible to completely get rid of the pollution of the motor, but it is quite realistic to minimize negative consequences.

To do this, it is necessary to pour only high-quality oil, which meets the manufacturer's recommendations. It is also very important to do this in a timely manner. In addition, it is necessary to propagately replace the oil-challenge caps, follow the operation and restore the cylinder-piston group, guide bushings and valves.

Engine pollution, contamination signs

Elevated oil consumption is the first sign of accelerated nagar formation. At the same time, it is at the time of turning off the engine formed the main layer of precipitation - viscous and solid components are seen on the heated surfaces. As a result, deposits are formed, which are quite difficult to rinse.

There are quite a lot of diverse methods of combating sediments and nagars, in particular ultrasound cleaning, flushing oil or auto chemicals with a high percentage of solvents in the composition. It is important to know that the flushing should not cause damage to filters, gaskets, rubber seals and working surfaces. There are a lot of dubious compositions that, when ingestion, the internal combustion engine is capable of scoring oil canals and an oil worker.

As a result, overheating of the old oil, which leads to very unpleasant consequences.

Wash engine in what cases washing is required

Washing engine is required in such cases:

1. When changing the manufacturer (brand) oil.
2. When changing the type (viscosity) of oil.
3. If you get into the low-grade oil, antifreeze or fuel.
4. When repairing an internal combustion engine when you need to open the head of the cylinder block.
5. When buying a used vehicle, whose past service is not known.

The washing of the motor is also needed because to maintain the absolute cleanliness of the engine insufficiently detergent properties of even the highest quality oil. Moreover, most drivers lose the pollution of the engine with dust. And it acts on the principle of Abrasive - erases pistons, piston rings, cylinder sleeves. In the engine, the dust falls into the wrong installation or clogging of the air filter and cracking the intake manifold.

With leaks in the engine oil, it gets fuel. It is capable of breaking the viscosity, change the consistency of the oil film on the pushers of the valves, cams, bushings and connecting rods. The lubricant of cylinders deteriorates, and the piston rings fail prematurely.

In diesel engines in case of incomplete combustion of fuel, soot is formed, which scores piston rings, or rather their grooves, which provokes them erasing. Metals, such as iron or chromium, are able to form in oil.

Washing engine, old grandfather washing, dignity and disadvantages

Wash the motor is recommended using gentle flushing or conduct any other procedures. There is an old grandfather method of gentle flushing of the internal surfaces of the motor:

1. Initially, it is necessary to merge the old oil. In the presence of a lift, for a complete drain, the vehicle should be slightly tilted in different directions.
2. Then pour new oil and replace the filter.
3. After that, the vehicle is operated for several days in standard mode.
4. Re-make the oil and filter replacement. Interestingly, with the first subsequent replacement of oil, it is produced several times faster than usual.

However, this method significantly loses in the efficiency of washing with a full-fledged auto chemical type MF5. I propose to figure out how it works and what advantages gives.

Washing engine, how to rinse the engine auto chemical type MF5, dignity and disadvantages

Components of this tool are capable of shooting Nagar and deposit.

As a result, a protective layer of metal ceramics is formed on the purified coatings, which protects against the wear of the cylinder walls. In addition, such an auto chemistry restores the elasticity of seals and pads, shears harmful oxides from oil, and it also makes it possible to identify the wear of the oil-giving rings and valves - if after applying MF5 in three hundred kilometers chimney and oil consumption did not decrease, then these nodes are subject to replacement.

In addition, the use of flushing MF5 is relevant due to the fact that modern oils actually do not contain oil elements, and the available additives are literally burning to the surface. The main advantage of the MF5 is not chemically aggressive solvents that are capable of harming seals, gaskets and the engine itself.

Tips of professionals

It is worth saying that the correct flushing of the motor is not able to harm him. However, it should be suitable for its selection and competently. And do not forget that without timely and integrated engine maintenance, the washing efficiency can become zero. You can learn more about flushing information from the following video.
