Diagnosis of engine malfunctions is usually carried out at service stations that have qualified personnel and equipment that is capable of this operation. Modern cars should be diagnosed only in branded car services, since the technologies for all brands are different. Of course, there are universal centers that are certified by various manufacturers. This certificate confirms the competence of the center in the field of these services.

Such equipment, as a rule, costs a lot of money, and its maintenance is beyond the power of small service stations, so you can not worry about the quality of service.

Diagnosis of engine problems can become much cheaper. This can be achieved simply by using the inquisitiveness of your mind. Sending the car to the service should be preceded by a simple engine diagnostics by candles, they can give a lot about the condition of the car.

No matter how complex a car engine is, no matter how many electronics drive it, it hasworking parts that tend to wear out. This wear and tear can be determined by the color of the candles. It should be remembered that this technique is applicable only to gasoline engines, since there are simply no diesels either.

Let's start with the worst - soot on spark plugs. If such a sign appears, then along with it you can notice oil consumption, as well as increased fuel consumption. In addition, the engine will become much more smoky. All this indicates wear of the piston group in the form of piston rings, as well as valve stem seals. Oil simply enters the combustion chamber. Probably, it's not worth talking about repair methods.

Diagnosis of engine malfunctions can reveal not only existing problems, but also “rudiments”, which then become a serious problem. It happens that soot is observed on the candles. It is also black, but is easily erased. In this case, it is worth adjusting the carburetor, or checking and, if necessary, replacing it. The problem here is that the fuel mixture is over-enriched with gasoline, which leads to soot formation on all surfaces in the combustion chamber. After adjustment, it is advisable to make sure that the malfunction is eliminated and let the engine run at medium and high speeds.

Among other things, the diagnosis of engine malfunctions allows you to increase its resource, since not all malfunctions immediately disable the unit. With some, the engine can work for 10,000 kilometers, after which it will “stand up”. This situation will be a disaster for everyone.car enthusiast.

There is also the opposite effect when there is not enough gasoline in the mixture. Then the engine is difficult to start. On the unscrewed candle, you can see a white coating. The solution to this problem is the same as the previous one.

Diagnosis and repair of the engine can be done at home, but this requires a solid set of tools, as well as enough time and effort. Knowledge in this area will not interfere. If you are not confident in your abilities, then you should go to a service station.
