Carburetor cars are becoming smaller every year. Leading automakers have long switched to the injection type of injection, which has a lot of advantages. This means less fuel consumption, and increased productivity, a more balanced fuel-air mixture, etc. Nevertheless, problems have also been added. The injector is more expensive to repair, in addition, its nozzles are often clogged, for the cleaning of which the Laurel agent is often used. This flushing has its pros and cons, which we will discuss in this article.
Why is the car injector clogged and how to deal with it
Most of the chemical compounds contained in the fuel, such as sulfur, olefin and benzene, form tar deposits in the vehicle’s fuel system. They are not removed by gasoline, as they are covered with a dense crust of brown color. The lower the quality of the fuel used, the more such deposits accumulate over time in the car.
It is logical that the efficiency of the car is reduced as a whole, as the nozzles get dirty. Due to the fact that the complex flushing of the injector is a rather labor-intensive procedure, many drive this way until a critical moment arrives. The car will start to troit, the engine will be unstable, and one morning you can not even start. To prevent this from happening, a liquid called "Laurel" is used. In this case, flushing the injector boils down to a few simple manipulations, which we will discuss in this article. It is also necessary to touch on the engine cooling system.
Are active additives good or bad?
There are a large number of both supporters of chemically active components, and those who categorically refuse to use them. Both the first and second are based on life experience, technical knowledge or simply the advice of specialists.
First you need to figure out how flushing affects the car system. We highlight the main strengths and weaknesses:
- chemically active components that can be called aggressive have a negative effect on all rubber gaskets and seals. This leads to their accelerated wear;
- if the viscosity of the additive does not match the viscosity of the oil, then it is strictly forbidden to use it, as indicated by the manufacturer on the packaging with washing;
- poor-quality products for removing oil deposits only make it worse (clogging the catalyst, candles), as a result of which there are more problems than good.
That is why not every car owner is satisfied with the result.
Why it is better not to experiment
Many try to put various experiments with flushing, which in most cases end sadly. For example, the washing concentration is changed. This does not need to be done, since almost the whole point of using the tool is lost. It does not give the intended result, but the money has been spent.
In addition, do not pour more than necessary, especially if there is not enough gas in the tank. This can lead to the fact that you simply do not get to refueling without incident. For example, soft washing “Laurus” at high concentration has an extremely negative effect on rubber seals, which can subsequently result in the replacement of gaskets and seals, and this is costly.
Means "Laurel": flushing the injector and engine
If you notice twitching while driving, unstable engine operation, problems starting in the cold season, then it's time to use detergents.
All work is quite simple to do on your own. For this, a special tool is poured into the gas tank every 5-6 thousand kilometers. True, such an event is carried out, rather, as a prophylaxis, rather than a "treatment". Nevertheless, even new car owners need to do this regularly. As for the Lavra, it is used in a slightly different way.
Rinsing sequence
First of all, we need the "Laurel" - a soft flushing of the engine. It is also desirable to have several liters of gasoline and a special watering can for pouring. In the proportions indicated on the can, we mix Laurel and gasoline, after which we find the tube going from the vacuum pump to the intake manifold, disconnect it and inject the mixture there.
It is necessary to start the engine and keep the revolutions within 2,500 thousand. In this case, constantly add fluid to the tube. At this time, the engine will be unstable, but this is normal. Sludge and large amounts of smoke may escape from the exhaust pipe . Exhaust at this time will be extremely toxic, so they better not breathe. We stop the engine and allow it to cool, after which it is advisable to replace the spark plugs with new ones, if they are not already of the first freshness. If the candles are new, it is better to put the old ones at the time of washing, since they can most likely be coked.
About flushing manufacturers
One of the most popular liquids with the most positive reviews is Laurel. This manufacturer has proven itself from the best side. This fluid must not be poured into the tank as indicated on the label. According to the owners, the average liquid rating is 4 out of five. Many say that a miracle is not worth the wait, but the tool copes with its immediate task as needed.
Another popular flushing manufacturer is Winx. Its cost is approximately the same as that of the "Lavra" (a little more expensive, but insignificant). As for the ratings, then there is also 4/5. True, experts note that Laurel washes no worse than Winx, but is less harmful to health. A tool like High-Gir is expensive, but it also cleans somewhat better. Well, now we will return directly to our topic.
The composition of the flushing additives
To understand whether it is harmful for a car to use this kind of cleaning or not, it is necessary to deal with components that wash the engine and injectors from soot. The main component is kerosene. It is an excellent tool for cleaning oil contaminants. For greater efficiency, chemically active detergents are added that allow almost complete removal of oil deposits on the nozzle channels.
About car cooling system
When antifreeze becomes an abnormal color, usually bright orange, this indicates the presence of rust in the system. In this case, flush the radiator and all channels. This can be done both independently and at the service station. As the main means, "Laurel" is suitable. Flushing the cooling system will take a lot of time, since in one approach, in case of severe pollution, the situation will not be improved.
The first step is to drain the old antifreeze from the system. Then we take "Laurel" and fill one can, then add distilled water to a minimum. We start the engine and let it run for about half an hour. After this, we merge and we see that there is a lot of rust in the pipes and radiators. It is advisable to repeat the procedure again in the same order. If rust is still standing out, then in the third step we simply use the distillate without rinsing. After the above procedures, fill in fresh antifreeze and enjoy the result.
Regular maintenance is the key to success
We have already figured out a little what functions Laurel performs. Flushing the cooling system, injectors and engine - all this is within the power of this tool. However, do not forget that in order to achieve maximum results it is necessary to conduct regular maintenance.
For example, after cleaning the nozzles, they become dirty again, however sad it may be. As a result, the situation is repeated. To avoid this, it is necessary to periodically use detergents, but not too often. When replacing antifreeze, which is performed once every 12-24 months, it is advisable to flush the system for prevention. In the same way, when changing spark plugs to new ones, nozzles and the fuel system as a whole can be cleaned. This will definitely not be superfluous, but you can sleep peacefully.
Laurel: flushing the cooling system. Consumer Reviews
The most reliable way to verify the quality of a particular tool is to check for yourself. However, this approach often leads to sad consequences. For this simple reason, before using the flushing, you need to see what motorists or service station specialists write about it.
As for the Lavra, today it is one of the most popular means in Russia along with High-Gear and Winx. Rinsing, according to reviews, has excellent detergent properties and is not very aggressive with rubber seals, although it has a negative effect on them.
The degree of contamination of the nozzles
As practice shows, not every car owner on time serves his car. This usually leads to even more serious consequences. As an example, it is worth bringing nozzles. They are responsible for the uniform injection of the fuel-air mixture into the cylinder. Over time, both the cylinder and the nozzles are covered with soot, as a result of which the efficiency of the motor decreases. Specialists distinguish three degrees of nozzle contamination:
- 5-7% - almost imperceptibly for the driver, as there are no signs of malfunction. Fuel consumption is slightly increased.
- 10-15% - twitching during movement is noticeable, dynamic characteristics drop, fuel consumption increases.
- 15-30% - a critical mark. Gasoline consumption rises significantly, the engine trips at idle, and often dies on the cold.
Based on the above points, we can conclude that the first stage is not so critical, in addition, only an experienced specialist can detect the malfunction. But the lack of action on the part of the driver leads to the second, and, accordingly, final stage. Here the situation is already more serious and requires special attention.
System protection after cleaning
There is no need to talk about the quality of domestic fuel. Often fuel contains a large amount of impurities that exceed all kinds of norms and environmental tolerances. In some cases, gasoline is diluted, which has a detrimental effect on the fuel system of a modern car. If you add to all this the difficult working conditions of the internal combustion engine (traffic jams, long work, overheating), then it’s not far from the breakdown. It is good if flushing the Lavr engine is used, reviews of which confirm its effectiveness. But few people use this tool regularly.
In order for the “iron horse” to work properly, it is advisable to protect the system with special fluids immediately after washing. If you adhere to the advice of experienced professionals and the manufacturer of the car, you can significantly extend the life of important components of the machine. This applies to the cooling system, fuel, brake, etc.
To summarize
So we have figured out how to perform and what is the need for washing nozzles. "Laurel", reviews of which all boil down to the fact that the tool is worthy of attention, copes with the task completely. However, one should not forget that the abuse of such a chemically active liquid can lead to the "eating up" of rubber seals and gaskets. For this simple reason, you must follow the instructions and not come up with anything extra.
Really high-quality washing "Laurus" - reviews repeatedly confirm this. The domestic manufacturer does not produce the product at the lowest cost, but recently its effectiveness is higher than that of the same Winx. Also, experts prefer to work with Lavra, which is not surprising, given the health effects caused by Winx.
The operation of the injector will be hassle-free if the system is periodically monitored and cleaned, as well as using Laurel flushing fluid. Please note again that it is not possible to fill the Lavr tank into the tank if it is written on the label! In the absence of any experience in flushing the injector and the cooling system, it is better to provide the opportunity for these specialists to take up. But here you need to be confident in the services of service stations, as there are often cases when they took money from the driver, but did not do their work, and if they did, then it is of poor quality. Therefore, always be vigilant.
