Kolikrát vám mechanik doporučil čistič vstřikovačů paliva? Vsadím se, že se to stává často a možná by vás zajímalo, zda čističe palivového systému nejsou „hadí olej“. Opravdu funguje čistič vstřikovačů? Dnes zjistíme, že se to pokusíme zjistit.
Čističe vstřikovačů jsou v podstatě rozpouštědla, která pomáhají čistit palivové cesty. Tyto lahvičky čističů palivového systému se nalévají do palivové nádrže. Začnou pracovat na vyčištění celého palivového systému tím, že rozpustí gumu a další zbytky shromážděné v palivovém potrubí. Přestože palivový filtr zabraňuje vnikání nečistot do systému vstřikování paliva, malé částice a gumovité zbytky často procházejí skrz. Zjistěte, jaké jsou příznaky špatného palivového filtru.
Čističe vstřikovačů paliva jsou hořlavá rozpouštědla, proto se v motoru za chodu spálí.
Tři z nejběžnějších přísad v čističi vstřikovačů paliva jsou polyetheramin, polyisobutylen a polyisobutylenamin. Pojďme pochopit, proč jsou přidány.
Polyether Amin: Polyetheramin se používá pro benzínové i naftové aplikace. Říká se, že snižuje vynechávání zapalování a klepání od motoru. Je také účinný při odstraňování přebytečné vlhkosti z palivového potrubí. Tato chemikálie opravdu pomáhá, když je v palivové nádrži starý plyn, který pouze blokuje palivové potrubí a nehoří.
Polyisobutylen: Podobně jako polyetheramin má i polyisobutylen podobné čisticí vlastnosti. Ve skutečnosti jsou si oba na nich svým chemickým složením dost blízké. Většina společností vyrábějících čističe vstřikovačů jej na svých produktech označuje jako „PIB“.
Polyetheramin (PEA): PEA se přidává do čističů vstřikovačů, aby mohl rozpouštět pevné usazeniny v palivovém potrubí. Pevné usazeniny mohou ucpat palivový systém a to snižovalo ovladatelnost vozu. Snížená dodávka paliva by také mohla zvýšit pravděpodobnost klepání. Jedná se o mnohem silnější chemickou látku než předchozí dvě, takže přidání příliš velkého množství může také způsobit problémy.
Zatímco čističe vstřikovačů paliva jsou na trhu již desítky let, nepodařilo se nám najít žádnou publikovanou studii vědeckého výzkumného ústavu. Dá se však s jistotou říci, že čistič palivového systému skutečně funguje. Ale pouze při správném použití.
Pokud je nahromadění usazenin příliš velké, pak jistě, běžná rozpouštědla na čištění vstřikovačů nebudou účinná. That’s because there are many laws and regulations that don’t allow companies to retail harsh chemicals openly.
In case of severe depositing and injector clogging, the injector cleaning machine is most effective. This requires injectors to be removed from the car and cleaned using pressurized cleaning chemical. This machine is used to clean severe clogging of injectors (video):
Carbon collecting at the intake valves
Fuel companies say that they already add additives that prevent carbon buildup. But the truth is that carbon buildup is a real problem that requires using fuel injector cleaners.
The back of the intake valve can collect a layer of carbon. This can reduce the velocity of fuel mixture and also prevent the valve to seal properly.
Apart from this, there are other areas that are prone to carbon buildup as well. This includes piston head, intake manifold and cylinder head. Fuel injector cleaner is the best solution to clean this carbon deposit. You can expect to see a better running engine after using an injector cleaner.
However, excess carbon buildup on the valves can only be cleaned by opening up the engine. If you are having a hesitant engine, then it’s worth trying out a good injector cleaner.
Reduced acceleration and fuel efficiency
The modern fuel injectors run on close tolerances through which pressurized fuel is pushed. For proper functioning, the injectors need to deliver an atomized mist of fuel when asked for. The clogging of the fine channels inside the injectors can disrupt its functioning.
When the spray pattern and pressure is not what is required, the car might start running rough. This also reduced fuel efficiency as the fuel droplets in the mist is not properly atomized. Fuel injector cleaner works well to solve this issue.
There are so many fuel injectors in the market today that it’s always recommended to read the directions first. If the concentration of fuel injector is too high for the amount of gas, then it might cause some damage.
Step 1) Pick a Fuel Injector Cleaner of your choice. There is an end number of fuel injector cleaners in the market. Go with a trusted brand at it should work out well for you. Our favorite ones are mentioned here.
Generally, a full bottle of the fuel injector is good for about 50-liter (13 gallons) of fuel. Your car’s fuel tank capacity can range between 35 to 70 liters (9.2 gallons to 20 gallons). Note the tank capacity of your vehicle from the owner’s manual.
Step 2) So how should you use it? It’s best to use fuel injector cleaner right before topping up your fuel tank . On your next visit to the gas station, pour out a bottle of injector cleaner into the gas tank first and then top up with fuel. Read instructions on the bottle of injector cleaner to know how much fuel you should add. When you add fuel, the injector cleaner will mix properly.
Now drive the vehicle normally. Remember:Let the fuel tank get near empty/in reserve before filling up again (Don’t dilute the mixture).
A je to. Your first cycle of injector cleaning will be complete after burning off this fuel mixture. Most of the time this is enough to notice some performance improvements but you can go another cycle if you’re not satisfied.
It’s often recommended to use a fuel injector cleaner every 10,000 km. However, if you suspect that the fuel quality in your area is not great then every 5,000 km will be a good choice.
But again, with so many injector cleaners with varying strengths, it’s best to refer to what the product manufacturer suggests. Know if you should use Octane Boosters
