How to care for diesel injectors?

A clogged atomizer, a damaged coil, an ineffective sealing washer are the little things that cause nozzles to stop working properly. Elimination of most single failures is not expensive and time consuming. But procrastination and ignoring its symptoms can seriously damage engine and exhaust system components. Then you will have a visit to the workshop, which can really cost a lot. Still, there are ways to take care of your injectors before it's too late. Which? We explain!

Shortly speaking

Diesel injectors are always replaced as a set. The vast majority of them can also be regenerated, although not always - due to the specific design of some models or increased wear - this is possible. In any case, if you suspect a breakdown, you should not postpone a visit to the mechanic and replace them. However, an even better solution is prevention: a non-violent driving style, the use of good quality fuel and engine oil, and the replacement of filters in accordance with the manufacturer's recommendations are enough to effectively operate the nozzles for up to 150 people. . kilometers.

We wrote about the most frequent breakdowns of diesel injectors in the previous article of this series. We also mentioned that many malfunctions are caused by improper operation and lack of necessary protective measures. To avoid the unpleasant consequences of neglect, you should follow some of the tips below.

Refuel with good fuel ...

The service life of nozzles is on average 100-120 thousand kilometers, although manufacturers claim that under ideal operating conditions they can drive another 30 thousand without fail. However, it all depends on how the engine works - in a word, on how you drive. And what are you riding. While using cheaper fuel may seem like a savings, the end result is likely to shock your wallet.

Derived from low quality diesel fuel. pollutionHis unfavorable biochemical compositionAnd also lower lubricating properties may cause clogged tips and seized and damaged fuel injection. Owners of engines with fine, precise Common Rail injectors will learn about the consequences of an improperly selected fluid. Better quality oil not only does not harm, but also protects the components of the injection system by flushing and lubricating them during operation. In addition, because the engine burns better, it uses less fuel and at the same time reduces gas emissions.

…more often

Diesels are also bad for driving on exhaust gases. An empty tank is a brick air supply to the injection system. Dry start is dangerous for the fuel pump as well.Sawdust rubbed off from this important part of the system during engine start without an adequate dose of diesel fuel will inevitably lead to injector failure. Therefore, it is better to refuel completely and not wait until the reserve on the dashboard lights up at the next oil spill.

Change filters and oils

And this is regular. For information on how often you should do this, refer to your vehicle manual and its manufacturer's recommendations. In the absence of such data, contact the service. Use both engine oils and filters from trusted brands.such as Castrol, Mobil and Motul. By the way, you can ask a mechanic to inspect rubber fuel hoses, which harden over time and begin to crumble, threatening fuel contamination and damage to injectors, as well as leaks from the system.

Use protection of the chemical injection system

They also serve to protect diesel injectors. special fuel additives that liquefy solid particles and remove impurities and carbon deposits, produced, among other things, by Liqui Moly. This type of preparation should be used for preventive purposes, however, remember that they are not able to XNUMX% protect the injection system from wear. Especially if - apart from filling them in the tank - you do not follow the rules for the correct operation of the engine of your car.

After using the nozzle cleaner, it is also worth applying a lubricant additive.

Some agents, such as Diesel Spulung, can not only be poured into the tank after refueling, but can also be fed directly into the injection system by attaching the container to the pipelines. However, don't forget to do never disassemble or soak nozzles in harsh chemicals.as this could permanently damage their internal components.

Don't forget about precision

If you are a handyman and like to tinker with your car, great. You probably constantly check the cleanliness of the nozzles and, if necessary, do not hesitate to replace worn tips or sealing washers with new ones. Just remember that you cannot force the nozzles and not regenerate individual elements of the system. The injection system is a delicate and fragile component that requires precision to function accurately. When you take apart a part, for reinstallation, use clean engine oil or silicone products.this will allow you to mount it well.

We always say: prevention is better than cure. Prevention in the automotive industry is a much more effective (and cheaper!) solution than repair. To make it easier for you to protect your diesel, we have prepared a wide range of spare parts and chemical additives to make driving really easy!
