If the technique is complicated, it often fails, and restore it - the pleasure is not cheap. When checking a diesel engine, which is equipped with a turbocharged and intercooler or, as it is also called an intermediate cooler, quite a few car owners can detect traces of oil in the intercooler. However, you should not immediately fall into a panic and prepare yourself to enormous financial costs. If you correctly determine the reasons why the turbine drives into the intercooler oil and to eliminate the discovered problem in time, perhaps the situation will be able to solve with minor losses.

Intercooler in diesel cars and in the machines with a gasoline engine

At first, the main purpose of intermediate coolers (intercoolers) was to install on diesel engines, because they are too sensitive to high temperature substances, and the spare radiator is able to reduce the air temperature, which comes out of the turbine from 50 to 75 degrees Celsius. But today, quite a lot of manufacturers, as well as, tuning workshops are already practicing the installation of intercoolers on gasoline engines.

What is the intercooler need what it gives

To cool the fuel mixture, after the turbine requires the installation of the radiator, which is the intercooler. It gives many advantages, I propose to consider them:

1. It significantly increases the engine power.

2. Reduces the content of toxins in exhaust gases.

3. Significantly reduces fuel consumption.

4. And the end itself, increases the elasticity of the engine, therefore, it reacts faster to changing the fuel supply.

Intercooler of diesel, device and principle

If you remember the course of the physics, which we passed in school, it is possible to emphasize that almost all substances are able to expand if they are heavily heated, and during cooling it is compact. If the vehicle design includes turbocharging, then the air in it passes through the supercharger, which moves by exhaust gases. As is known, exhaust gases are distinguished by very high temperatures, which produces to heat up to 150-200 degrees Celsius, which is used in the fuel mixture. As a result, the mixture is capable of greatly expanding, becoming different and inhomogeneous, which leads to incomplete combustion.

It is worth noting that air intercolers are very often come across, which are a design that is very similar to the usual radiator of the cooling system. They differ only in that they pass instead of fluid through the inner cells of the air. They are much more practical and cheaper, but for installation it is necessary to have a lot of free space under the hood. Liquid intermediate coolers are not so overall, however, require the use of the electronic control unit and its own pump. But, in any case, you can detect oil there, regardless of the intercooler design.

Oil in the intercooler, reasons

When oil detected in the intercooler, you should not succumb to a panic, it is possible that you will eliminate this problem yourself and in just a couple of hours. To begin with, you need to check the drain oil pipe located between the engine crankcase and the turbine. It should not contain significant bends, since if the drain pipe is bent, an increased pressure will arise in the turbine, it will urge the oil through the seal rings, and it, in turn, will fall into the intercooler. Such a pipe is created from rigid and dense materials, however, is capable of deforming with long-term operation. To solve the problem, it is enough to align the pipeline and in this position and secure it.

How to solve the problem in the drain oil pipeline

But it is not always possible to get sick of trouble. Sometimes oil may appear in the intercooler pipe due to disorders associated with the engine crankcase. This is due to the formation of various blockages in the drain oil pipeline - the usual garbage can fall into it or to form a nagar. Often, drivers, with self-repair of a diesel engine, do not use specialized funds to fasten the oil pipeline, they use ordinary sealants that are capable of penetrating inside the tube and form traffic jams. You can solve the problem with a drain oil pipeline, flushing it and reading it, however, it is necessary to act neatly, in order not to damage the walls of the tube.

How to solve the problem if the duct filters are clogged

If the oil appeared in the intercooler, it is also necessary to inspect the air duct leading to it, for cracks or holes. In addition, if the filter is badly scored, it will not be able to skip the right amount of air. In any case, in the middle of the supercharger, a certain area of \u200b\u200bvacuum is formed, capable of pulling oil and gradually destroy the sealing rings, thereby contaminating the intercooler. As for solving the problem, it is necessary to clean the filter and make it a replacement at the first opportunity. Also, the holes in the air duct should be eliminated.

However, there is another option to develop events. If in the crankcase lubricating material rises above the drainage nozzle, the turbine can also throw oil into the intermediate cooler. If you have moved with the scale of the oil used, the situation can be easily corrected. But if the crankcase ventilation is broken, then the problem is quite serious. The reason for this may be the destruction of the wholeness of the sealing rings in the cylinder-piston cycle, which is why the spent gases fall into the crankcase and squeeze the oil by drain pipe.

Clean the intercooler according to the instructions, the course of the work has phased

Even if the problem is detected and eliminated, the intercooler itself must be cleaned. If this does not produce, then the lubricant will be mixed with air, which passes through the radiator and fall into the fuel, thereby significantly worsening the quality of its combustion. In addition, the air cooling efficiency in the intermediate cooler will significantly decrease, which can deprive the vehicle benefits derived from the intercooler installation. In some cases, when the engine overheating, oil can light up.

In order to produce integrated intercoule cleaning, it takes dismantling. More similar devices that are called air intercoulers are quite easily removed. To do this, you just need to unscrew a couple of bolts and break the clamps. As for liquid models, everything is much more complicated. It is necessary to carefully read the instructions for the car's work, in order to find out what means you can wash the intercooler from the oil, often manufacturers provide a list of permissible substances. If for any reasons to do it fails, it is recommended to apply the universal auto chemistry.

Very often, you can find various recommendations on the Internet, for example, on the use of kerosene, gasoline or other means, but not recommended to use them without consultation with a professional. There are intercolers, as part of which there are materials that can be damaged by solvents or flammable, which can produce to strong and irreversible damage to the element of the power apparatus. In this case, you can use the services of specialized service centers, the truth will fly to you "in a penny".

The intercooler must be rinsed in accordance with the instruction that must be indicated on the packaging of the cleaning agent, and the residues of chemistry wash off with water. Remember that the cells of the radiator can be quite easy to damage under the high pressure of the fluid, it is necessary to pour water under weak pressure. The cleaning procedure must be repeated several times, until water leaves from the intermediate cooler. Then, you can blow the mechanism with warm air, but not too high temperatures. Also, it is worth cleaning the device from external contaminants and mounted back to the vehicle motor.

Tips of professionals

If the problem described above is detected, it is required to immediately stop the operation of the car and to engage in its diagnosis. If you can not detect and troubleshoot, you need to contact the service center.
