De bästa rengöringsmedlen för bränsleinsprutare

Allt eftersom tiden går kanske din bil inte accelererar lika snabbt som den en gång gjorde; motorn kanske inte går så smidigt som du minns; eller så kan bränsleekonomin sjunka - men allt annat kan fungera bra. Om det händer kan det vara dags att rengöra din motor med den bästa bränsleinsprutningsrengöraren du kan använda. Bränsleinsprutningssystem är elektromekaniska högprecisionssystem med snäva toleranser som arbetar under mycket höga tryck, och allt bränsle måste pressas ut ur insprutare med små utlopp.

Även om du är försiktig med att använda det rekommenderade bränslet för din motor, kan föroreningar fortfarande ta sig in i ditt bränslesystem från bensinstationens underjordiska tankar. Korta turer och stopp och kör kan också ge en möjlighet för partiklar att sedimentera och för lack att bildas, vilket minskar din motors effektivitet – och kraft.

Att ta din bil till en mekaniker för rengöring av bränsleinsprutare innebär att du tar bort insprutarna från motorn och utför servicen på en bänk med specialmaskiner. Det är en dyr process, så det är värt att prova själv först. Bränsleinsprutningsrengörare är förmodligen den enklaste motortillsatsen att använda och förare kan göra det även om de inte har några verktyg eller ett garage. Med dessa produkter kan du helt enkelt applicera en bränsleinjektortillsats på din bränsletank, rensa ut det inre av din motors bränslesystem och minska risken för att du behöver utföra kostsamt underhållsarbete någon gång på vägen.

Förare som letar efter rengöringsmedel för bränsleinsprutare är bortskämda med en enorm mängd alternativ, men vi har gjort en lista över de bästa bränsleinsprutningsrengörare på marknaden idag för att göra ditt köpbeslut enklare.

Everything You Need to Know About Fuel Injector Cleaners

Removing fuel injectors and and cleaning them outside the engine is a tough job for a home mechanic. Photo credit:Banglens / Shutterstock.com.

One of the most common problems with any fuel injected engine is that the injectors that bring the fuel to the combustion chamber can get clogged up. If you think about it, these are one of the vital parts of the engine—no fuel in the chamber means no combustion, and consequently a car that will lose power, have worse fuel economy, and increased emissions.

If you’ve never experienced your engine losing power even if it was regularly maintained, you are one of the lucky few. Clogged up fuel injectors are so common that every auto parts shop has dozens of different fuel injector cleaners that purportedly can clean your entire fuel system and make your engine work like new again. That is, if it doesn’t have other problems already.

Here, we’ll talk about everything you need to know about fuel injector cleaners and we try to answer every question you have, like why they are needed in the first place, how to use them, should you use them yourself, or go to a mechanic, and so on.

How Do Fuel Injectors Work?

Fuel injectors are used to introduce fuel to the combustion chamber, where it is mixed with air and then combusts to create power. The injector receives the fuel from a high-pressure fuel pump and thanks to a very small nozzle, atomizes the fuel so it can mix with air quickly.

It’s a little like an aerosol spray can:A bottle already pressure with a small nozzle that atomizes the liquid into very small particles. The fuel injector works similarly, with higher much pressures, smaller nozzles, and precise metering to create a fuel vapor that combusts predicably, efficiently, and cleanly. Newer injectors for direct injection engines even have several nozzles on the tip to help for a better air-fuel mixture.

Since carburetors were phased our around 1980, every new internal combustion engine gets the fuel into the chamber with injectors, including diesel engines (don’t use a gas engine-only injector cleaner in a diesel, though). The process is controlled by the ECU (engine control unit), so the injector will always supply the fuel right when the engine needs it. Timing is very important, as injecting fuel too early or too late can will the engine not to work as expected or even damage it.

Fuel injectors are very delicate parts, with very small canals and constantly under high pressure, and need almost ideal working conditions, like extremely clean fuel and in the case of direct injection systems, a clean nozzle tip and a clean combustion chamber.

How Do Fuel Injectors Clog Up?

The gasoline and diesel fuels that we put in our cars are never as clean as it should be. In addition to fine particulate matter, the fuel that we get today has small amounts of water and some octane-boosting ingredients.

All of these things can have detrimental effects on the fuel injectors, but the number-one enemy is definitely carbon buildup. This is something that happens to every engine with time—during the process of combustion, the majority of the carbon leaves the engine through the exhaust system, but some of it stays in the combustion chamber and in time it can block the passages of fuel and air-fuel mixture. Add to that the possibility of the injector rusting from the water in the fuel, and some byproducts from the ethanol, and your car can start losing power and consume more fuel.

This is why keeping your fuel injectors clean is important. You not only lose power, but your fuel economy can fall off too.

What Does a Fuel Injector Cleaner Do?

Fuel injector cleaners are additives that are meant to dissolve those deposits in the injector, as well as in the combustion chamber, and help your engine work in optimal conditions with the right air-fuel mixture. Think of them as detergents for your fuel system.

These cleaners can clean the inside of your injector, as well the carbon buildup in the combustion chamber, behind the intake valves, and around the spark plugs. All of them have active ingredients that help dissolve the deposits into much smaller pieces, which are either burned or ejected through the exhaust system.

How Do Fuel Injector Cleaners Work?

Fuel injector cleaners are a mixture of complex chemicals, most of them solvents that can easily clean deposits. The main cleansing agent of these additives is a chemical called PEA or polyetheramine (see the next section), which is a nitrogen-based detergent that is great at dissolving carbon deposits. PEA is very resistant to high temperatures, which makes it great for cleaning fuel injectors, as well as dissolving deposits in the combustion chamber, where the temperature can go up to 1200°F.

Some cleaners contain other chemicals that the manufacturers claim it makes them superior to others, but scientific studies have shown that polyetheramine is best at cleaning carbon build up, and you should always look for additives that contain this chemical.

What To Look For in a Fuel Injector Cleaner

Always look for a fuel injection cleaner that contains the detergent Polyetheramine (PEA), as it is the strongest cleaning agent. Some of the cleaners will have Polyisobutene (PIB), that helps remove water from the fuel and Polyisobutylene amine (PIBA), which is also a cleaning agent, but not as strong as Polyetheramine. Older fuel injector cleaners even have alcohol in them for water removal, but they can damage parts of the fuel system and you should avoid them.

When Do I Use Fuel Injector Cleaner?

These cleaners are some of the easiest to use engine additives on the market. They should be poured into an almost empty tank of fuel just before you fill up at the gas station, and then you should drive until the tank is almost empty, so it doesn’t get diluted by fresh gas.

This means that they don’t work right away—you need to drive several hundred miles before you can feel the difference. Be sure to read the instructions:Some formulas are concentrated, so you’ll need to measure it out, while others just use the whole bottle.

If your car was not cleaned for a long time and it has a lot of carbon deposits, one full tank of gasoline or diesel and a bottle of fuel injector cleaner might not be enough to effectively clean the injectors and the combustion chamber. When that’s the case, simply put another bottle of additive in an almost empty tank of gas and empty it by driving.

How Often Should I Use Fuel Injector Cleaner?

If your engine is running fine, never. It’s a waste of money. But if you have problems, or as your car starts to age, some mechanics will advise you to use a fuel injector cleaner every year, or every 12,000 to 15,000 miles, before the oil change. Additive manufacturers will even instruct you to use it every 3,000 to 5,000 miles. These are not rules. We would advise against using these additives on new engines, as your engine may not be fully broken in for up to 10,000 miles, and the only thing you should be putting through a new engine is high-quality gasoline.

When to use fuel injector cleaner

Our advice is to use fuel injector cleaners on older engines before an oil change, as well as engines that are often used in cold climate and driven on shorter distances or in congested stop and go traffic. In these situations, carbon builds up much faster and using a fuel injector cleaner will help in maintaining the optimal working conditions of your engine.

Using a higher quality detergent gasoline or diesel fuel will also help against clogging up of the injectors and less carbon build up, so try to stick with name brands, and use the recommended octane. Many new high-performance and turbo engines require at least 91 octane, and using a lower blend is a recipe ending up with engine deposits.

How DoI Know If My Engine Needs a Fuel Injector Cleaner?

Engine with a lot of carbon build up and clogged injectors will start losing power, begin to consume more fuel, rattle at idle and have ignition problems. However, all those symptoms can be due to other parts of the engine, so be sure to always maintain your car routinely by regular oil, oil filter, and air filter changes; as well as spark plugs in gasoline engines. Vacuum leaks, short circuits, and weak charging can also affect performance, so if you’re in doubt, hook up an OBD2 diagnostic scanner to try to narrow it down.

What Can I Expect After a Fuel Injector Cleaner Treatment?

You can expect several improvements on your engine after treating it with a fuel engine cleaner, but these results won’t happen immediately—you often have to drive a few hundred miles for it to work. Improvements include regaining power and enhanced throttle response, better fuel economy and fewer vibrations at idle. For best results though, it’s best that you check your spark plugs and air filter as well, as they can also help your engine run better.

What Are the Types of Fuel Injector Cleaners?

There are several types of fuel injector cleaners out there. The basic ones will only clean the fuel system and the carbon build up inside the combustion chamber. However, there are cleaners that will also stabilize the fuel or even boost the octane value to help the engine run smoothly even on lower quality gasoline.

Some of them will even have lubricants that can help maintaining the fuel system of your car for longer periods of time. You can recognize all these products right away:They will either have “3 in 1” or even “5 in 1” description on the package.

How to Use Fuel Injector Cleaners

Keeping your fuel injectors clean play a huge role in how efficiently your car’s engine is running. Using fuel injector cleaners is an easy way to make sure your car is operating at its peak and also getting better fuel efficiency.

Using fuel injector cleaners is a pretty simple task and anyone can do it—there is no need to go to a mechanic. Before you begin, it’s important to use a fuel injector cleaner on a close to empty gas tank just before you’re about to fill up at a gas station.

  1. Buy the right fuel injector cleaner for your engine
    1. All fuel injector cleaners are not created equally. Most of them will work on any type of fuel, but there are some that will work only on gasoline, diesel, or ethanol blends. Also, you should check if it works with turbo engines, if you have one, or with catalytic converters. Read the instructions on every package thoroughly, so you can be sure that you’ll buy the right one for your engine type.
  2. Check the instructions for the right amount of fuel injector cleaner you need
    1. The instructions will help with measuring the right quantity you need for the size of your tank as well. Almost always, one bottle of a fuel injector cleaner is enough for one tank, but if you have larger or smaller than the average fuel tank, you may need to put more or less of the additive.
  3. Be sure that the fuel level in your car is low
    1. Fuel injector cleaners can work even if you put them inside a full tank of fuel, but it’s best to put them inside an empty tank, so they will mix with the fuel better.
  4. Remove the fuel cap
    1. Remove the fuel cap, as every cleaner should be mixed with gas.
  5. Pour the fuel injector cleaner into the fuel tank
    1. Open the bottle and pour the fuel injector cleaner. Use the funnel if one is provided with the bottle so nothing spills out. Some bottles have additional measuring devices on them (attached to the bottle). Be sure to fill them with the right amount of cleaner before pouring it into the tank.
  6. Refill your tank with fuel
    1. After pouring the fuel injector cleaner, you should refill your car with gasoline, diesel or any type of fuel that your car uses. That’s why it’s ideal you are at a gas station while doing these steps. Dispose of the empty bottle responsibly.
  7. Empty the fuel tank by driving your car. This is self-explanatory, but there are some things to consider if you want the best cleaning.
    1. It’s best to drive your car at the highway or at higher speeds. In doing this, the pressure in the fuel system will be higher, which can help the cleaner remove the deposits easily. This will also help in cleaning the carbon deposits inside the combustion chamber and eject them through the exhaust.
    2. Use higher engine rpms. You can do this even when the car is stationary, or when driving. In other words, don’t hesitate to press that gas pedal, as it will help in better cleaning.
  8. Repeat steps 1 to 7 if needed
    1. One bottle of fuel injector cleaner usually does the trick if your engine has deposits inside or some of the injectors is stuck. However, if the engine is still not working as normal, you can repeat steps 1 to 7. These additives don’t have adverse effects on the engine and using them more than one time is not a problem.
