A modern car requires regular maintenance. This also applies to the fuel system, which inevitably becomes polluted over time. This happens because of the low quality of the fuel, in particular, due to the large number of organic compounds. Let's talk about which and, most importantly, how and when to use the nozzle cleaner for a diesel engine. Consider the main nuances and problems that may arise in the process.
Key Points
Despite the fact that diesel fuel is primarily designed to ensure the cleanliness of the cylinder-piston group of the engine, this is far from always possible. The reason is the low quality of fuel and the presence of chemical compounds prone to coking. Of course, when burning fuel, soot forms, especially on the bottom of the cylinders, where it is extremely dense and has a dark color. Lighter oily soot appears on the nozzle needles and sprayers.
As a result, the combustion chamber decreases in volume and heat transfer to the cooling system is worsened. Overheating can lead to overhaul of the engine. On diesel engines , burners are most often burned. An incorrect spray pattern of the mixture forms, its quality deteriorates. Here we have all the consequences: this is unstable engine operation, increased fuel consumption, worsening acceleration dynamics.
CIP engine
Quite a long time ago technologies and tools appeared that made it possible to remove soot from the cylinder-piston group without special efforts, and also to clean the engine and fuel system of the consequences of fuel combustion. The additive package for cleaning a diesel engine is quite extensive, it consists of a large number of components. For example, an increase in operational properties is achieved through the use of antifoam agents and cetane-raising components.
In addition, various markers, perfumes are included, but this is also done at refineries. The immediate purpose of the package of detergent additives is to remove carbon deposits on the needle and the nozzles themselves. As a result, the spray torch becomes normal and the system operates in the optimal mode for itself. Today, the most popular diesel injector cleaner is Hi-Gear. Reviews have repeatedly confirmed this.
Methods for cleaning the fuel system
Currently, additives are used that are added directly to the gas tank of the car. The procedure is usually repeated every 3-5 thousand kilometers. Everything is pretty simple here. Detergent is diluted with fuel in a certain ratio, added to the tank. It will do the rest for you by itself.
Another indiscriminate method has a slightly different approach. The hose going to the fuel pump of a car is removed and placed in a prepared can with a cleaner. After that, the engine starts, and at idle, liquid is generated from the can. It is worth paying your attention to the fact that the effectiveness of this method is extremely high - the result is immediately noticeable. Deposits and varnish deposits are removed from the nozzles. Often, this approach allows you to clean the motor no worse than ultrasound.
Diesel injector cleaner: reviews and recommendations
Many owners share their impressions after using the product from one or another manufacturer. In particular, we are talking about a package of detergents "High Gear". Reviews say that if you follow the technology and instructions, the result will be positive. The following improvements are usually noted after using Hi-Gear:
- increase in acceleration dynamics;
- more stable engine operation;
- reduction in fuel consumption;
- reduce wear.
In addition, such tools provide some protection of the motor against corrosion. Of course, the procedure should be regular, because only then the system will always be in optimal condition.
Diagnostics and adjustment
It often happens that motorists are dissatisfied with the action of the tool. Sometimes this happens due to savings. For example, if, instead of a proven manufacturer, you give preference to an unknown and also cheap brand, then you can "get".
Another obvious reason for not achieving the desired result is a mechanical failure of the node. If you do not perform diagnostics and adjustment work before using the flushing, then you may not know that the cause of the malfunction is not in sunburn, but in something else. Therefore, it is advisable to go to the diagnostics before flushing the system and remove the associated problems, if this is, of course, possible.
Using a compressometer
Often the main reason for the deterioration of dynamics and increase in flow rate is the pressure drop in one or several cylinders. This can happen due to occurrence or burning of rings, high wear of the cylinder-piston group, as well as its deformation.
Nevertheless, in the presence of at least one of the above malfunctions, there will be symptoms. In this case, the nozzles can be clean and do not need to be washed. To understand what’s the matter, it’s better to check engine compression. It is desirable that the work was performed by a qualified specialist at the service station, but if you have a compressor, you can handle it yourself. If everything is in order, then you can use a package of detergents.
If there is a mechanical malfunction, we first correct it, and then wash it.
"Laurel" - diesel injector cleaner
One of the most popular and effective means of domestic production is the product "Laurel". The additive package can be compared with Winx, but its price is slightly lower, and the effectiveness, according to experts, is higher. One of the key factors characterizing the product is its detergent and protective properties. Laurel copes with such tasks very well.
In addition, the additive package used, although it contains chemically aggressive compounds, is in small quantities. This suggests that the rubber seals, gaskets and seals will not fail. Although here it is also necessary to know the measure and not to use the remedy too often or not according to the instructions. In general, Laurel is a competitive and effective tool that can improve the situation with the fuel system for the better.
Injector cleaner for diesel Liqui moly
Liquid Moths is recommended for use with BMW and Mitsubishi diesel engines. This already indicates the high quality, as well as the effectiveness of the product. The tool contains a highly effective additive package that easily removes dirt from nozzles and engine cylinders. It is also noteworthy that only 500 ml of the product is sufficient to eliminate contamination. The same "Lavra" would take one liter. Although, given the price, it turns out the same thing.
The professional tool "Liquid Moths" - a cleaner for diesel injectors - can cope even with the most deplorable situations. Preventing souring of nozzle needles is the key to a detergent package. Also, for some time you will receive corrosion protection, which is also important. Of course, the tool is not a panacea for the treatment of all diseases of your "iron horse", but it has decent reviews from consumers, and is also the original for BMW, which already says a lot.
High Gear and its key features
The manufacturer of this detergent is a well-known American company. Often you can hear a lot of positive reviews from both ordinary drivers and high-level specialists. Most tests show that regular use of Hi-Gear can significantly reduce the wear and tear of high pressure fuel pumps, and also keep the engine and nozzles in good condition.
American experts conducted experiments for several years. Took several identical brands of cars. The conditions and duration of operation were identical, only some used the additive package for cleaning, while others did not.
A few years later, the motor was inspected, which showed that the tool coped by five points. The high pressure pump, as well as the nozzles and the needles themselves, were in good condition. At the same time, the second group of cars had a significant degree of pollution and wear.
All this confirms the high quality of the package of detergents and, in fact, their feasibility. Along with great effectiveness, the tool is extremely high in price, which stops many when buying. But it’s better to give an extra thousand and get a certified and quality product. Although there is a risk to stumble on a fake, so you need to buy in trusted places.
Draw conclusions
Much has been said about tools such as High Gear, Laurel, and Liquid Moths. The nozzle cleaner for a diesel engine, regardless of manufacturer, must fulfill its main tasks - to wash and protect. Both an American-made product and a domestic one have their strengths and weaknesses. Nevertheless, today many people still prefer to periodically clean the fuel and cooling system. This extends the life of parts and assemblies, and also improves the performance of the car.
As for funds of dubious origin, it is better not to use them. This is due to the fact that the low quality of the washing additive package, although it cleans, but does it in its own way. As a rule, cleaned carbon is spread throughout the system and ultimately enters the catalyst and clogs it. A high-quality product burns carbon deposits, leaving no trace of it. At the same time, the exhaust system of the car is less affected. As you can see, there is a difference. And sometimes it makes sense to overpay a little and get the same "High Gear". A cleaner of diesel injectors of this quality will not fail.
