In-car maintenance, there are several practices you need to perform for the car to be in good shape, and it is no surprise that there are some that you may not have heard of it. Among them is the fuel induction service, which is typical for direct injection engines.
It is more of a cleaning process, targeting parts, such as the intake manifold, throttle body, and intake valves.
Does your car need the fuel induction service? This is a good question that we will help you answer based on our vast experience in the auto-engineering scene.
An in-depth look at this service will explain what it is, how it takes place, and why it is necessary for vehicles.
What Is The Fuel Induction Service?
Simple science is what vouches for anything that clears out carbon deposits from an engine. These carbon deposits are detrimental to the performance of the engine as well as its life in the long run.
Over time, they can build up from the impurities in the fuel and fuel additives. This can slow down, or in worse cases, choke, the free flow of fuel.
The rest is simple logic. The engine runs on fuel. If there’s not as much free flow of fuel, the engine will perform less efficiently.
This drop in efficiency can be witnessed across the spectrum of engine performance. Be it outright acceleration, emission outputs, towing capacity, fuel efficiency, or general reliability, you can see its effect clearly.
This should easily establish that the carbon deposits are bad. Fuel induction services are looking pretty sweet right now, are they not? Carbon deposits are bad.
Anything that gets rid of it is good. So, fuel induction services, overall, should be good. We wish it were. But, sadly it is still a long debate. Let us explain why.
How Fuel Induction Service Works?
The science behind fuel induction service is rooted in understanding the intricate network of components responsible for delivering fuel and air to the engine.
The fuel induction system begins with the fuel tank, which houses the fuel pump that pumps fuel to the engine.
The combustible mixture is formed when air and petrol traverse through the fuel lines to the fuel injectors.
The injectors dispense a mixture into the engine’s combustion chamber, where a spark plug ignites it to generate the drive essential to propel the automobile.
Toxins like carbon residues, dust, and fragments aggregate in the fuel system over a long period, ultimately leading to fuel injectors, intake valves, and throttle body congestion.
This buildup restricts the passage of fuel and air to the engine, thus causing a decrease in engine power, diminishing fuel proficiency, and escalating emissions.
Fuel induction service removes contaminants and deposits from the fuel system, restoring optimal engine performance.
This process involves using specialized equipment and cleaning solutions to dissolve and eliminate buildup from the fuel injectors, intake valves, and throttle body, among other components.
High-pressure equipment injects the cleaning solution directly into the fuel injectors, intake manifold, and throttle body, ensuring that all components are thoroughly cleaned.
Common Signs You Need a Fuel Induction Service
Like many car issues, you will see telltale signs that indicate you have a carbon buildup problem, calling for fuel induction.
The problem is that, at times, you may not know that you have this problem unless your mechanic lets you know. Let us look at some of the signs that may prompt you to seek this engine maintenance service.
#1. Check Engine Turns On.
One of the first signs that will indicate you have an engine problem is when the check engine light turns on.
The carbon accumulation may prevent sufficient airflow into the intake manifold. The carbon deposits may also lead to the formation of hot spots that can lead to the engine overheating.
This is one of the reasons why the check engine turns on and you need to check on it immediately before it wears further.
#2. Loss Of Power.
Another sign that you may have a problem with your car’s combustion unit is when you notice that there is a loss of power.
You will notice this issue when accelerating or going uphill. The power loss comes due to the effect of the carbon on the air to fuel ratio, where it is somewhat irregular. This leads to improper burning of the fuel and the energy yield may not be sufficient.
#3. Poor Fuel Economy.
The dirt in the air inlets will bring in insufficient air, causing a drain of your fuel tanks to supply more fuel in the combustion chamber.
This leads to black smoke and poor fuel economy, where the vehicle will consume more than the standard limit. A poor fuel economy means you spend more on fuel, which is bad for your pockets.
#4. Fuel Smell Inside The Car.
The fuel smell inside the car is another sign that indicates you may need a fuel induction service. The smell comes due to the irregular mixture, where too much fuel goes into the chamber to match the poor air intake.
The excess fuel supply may lead to a gasoline stench in the vehicle. Initially, it may be bearable but with more carbon deposits, it will be too much, especially when accelerating.
#5. Car Shaking On Idle.
You may also notice the car shaking when on idle. There are many causes of car idling, such as worn-out spark plugs, though an irregular fuel supply can also bring this problem.
Focusing on the carbon deposits, the issue causes an irregular supply of air and coolant, especially when it clogs the injectors, EGR valve, and air intake valves.
#6. Excess Emissions.
Another point that you may need a fuel induction service is if you have excessive emissions. It comes from the improper burning of fuel in the engine as there is no sufficient air supply for this process to go on smoothly.
You may notice traces of soot or carbon in the exhaust pipe, which may be too much than normal. Excess emissions are harmful to the surroundings and you may land in trouble with relevant authorities if you do not deal with the issue promptly.
#7. Rough Driving.
You may notice that the car does not do well when on the road, and it may jerk, fail to accelerate, or in severe situations, stall.
In case of such events, your engine might be wearing fast due to the effects of too much carbon. It may overheat fast and it may result in a rough driving experience.
In case you see a combination of these signs, it is prudent that you seek immediate attention from your mechanic.
What To Expect During a Fuel Induction Service?
You’re probably familiar with the standard oil change, but not so much with a fuel induction service. This service is important for maintaining the health of your engine and preventing long-term damage.
Here’s what you can expect during a fuel induction service:
- The battery will be disconnected: That’ll help prevent any electrical issues while the mechanic is working.
- The air filter will be inspected: A dirty air filter can affect the quality of the service, so the mechanic will make sure it’s clean before proceeding.
- The fuel injectors, throttle body, and intake valves will be removed: This is so they can be cleaned with a special solution.
- The fuel injectors and intake valves will be reinstalled: The battery will also be reconnected.
- Finally, the mechanic will test-drive the car to ensure everything is working properly: If everything looks good, they’ll give you the green light to hit the road!
Benefits of Performing Fuel Induction Service
A fuel induction service offers several potential benefits for your vehicle:
- Restored engine performance: By removing carbon buildup, the service can restore lost engine power and improve overall responsiveness. This can be particularly noticeable if you’ve been experiencing sluggish acceleration or a general lack of power.
- Smoother engine operation: Cleaning the fuel and air intake system can lead to smoother engine operation, reducing or eliminating issues like rough idling, hesitation, or uneven running.
- Improved fuel economy: A cleaner engine can burn fuel more efficiently, potentially leading to improved gas mileage.
- Reduced emissions: With cleaner combustion, harmful emissions can be reduced.
- Restored combustion chamber pressure: Removing carbon buildup can help restore proper compression in the combustion chambers, further enhancing engine performance.
What does this service include and how is it performed?
These would be the steps included in a fuel inductor service if a mechanic workshop were to do it. As you can see, much of this is stuff you can actually do yourself at home.
#1. Intake valve cleaning.
This step is done by spraying a special liquid into the intake valves while the engine is running.
This feeds the engine with throttle cleaner fluid and the air, which gets into the mixture and is ignited. This cleans the carbon deposits inside the intake and the intake valves.
The compound breaks up the deposits inside, and the remains are let out via the exhaust. A similar variant of this step can be made by yourself at home with the help of seafoam.
#2. Throttle body cleaning.
This is an optional service for a fuel induction, depending on the workshop. Sometimes the throttle body is just cleaned by the injector cleaner entering the engine.
But if a throttle body cleaning is performed, the mechanic or technician would first remove the throttle body from the engine. A particular compound called the throttle cleaner is used to clean the carbon. This is a liquid substance and comes in spray cans.
#3. Fuel Injector Cleaning.
This is also an additional service that your mechanic sometimes offers when you are doing a fuel induction service. This includes filling a special additive into the fuel tank, which will clean the fuel pump and fuel injectors.
There are special injector cleaner additives that do this job for you, and it is something you can do yourself just by buying one of these.
How Often Is A Fuel Induction Service Needed?
The standard recommendation for a fuel induction service is every 30,000-60,000 miles, based on the manufacturer’s specifications.
It is not a service like an oil change, where you must perform one every 3,000-7,000 miles, depending on the make and model of the vehicle and recommendations provided in the owner’s manual.
Fortunately, that means that fuel induction service costs are affordable and support the longevity of your engine while saving you a few bucks at the pump.
However, you do not have to wait for that 60,000 mark if your car is performing poorly. Car maintenance guides will typically advise that you consider them if you have noticed that your gas mileage has decreased.
It is also recommended if you experience engine problems. The process is an affordable way to solve and prevent problems.
For example, a GDI fuel induction service costs far less in the long run than servicing a struggling engine after build-up has put too much strain on its performance, which brings us to a typical customer concern.
- Smooth and fast acceleration.
- Improved fuel economy and engine performance.
- Optimum air-fuel balance in the system.
- Reduced emissions.
- The throttle, intake valves, and injectors will be clean and less likely to wear.
- A smooth driving experience, especially in the case of diesel induction service, targeting diesel-run vehicles.
Fuel Induction Service vs. Fuel Injection Service
One may confuse fuel induction and fuel injection services and think that you can use the two terms interchangeably. That is not the case as they refer to two different services. However, the two perform almost similar functions; cleaning engine parts.
Fuel injection targets the fuel system, more so the injectors, which supply fuel to the internal combustion engine.
The injection system is also prone to carbon buildup over time, leading to issues such as poor fuel economy and low power on acceleration. These are similar issues to carbon accumulation on the throttle body and intake manifold.
So, how do the two services differ? The difference is their target point in the combustion system. The fuel induction service cleans the air inlets, getting rid of carbon in places like the throttle body, air intake valves, and intake manifold.
On the other hand, fuel injection targets the fuel system, from the injectors to the lines. The two services are necessary if you want a proper air-fuel mixture that will burn efficiently and assure you of a smooth driving experience.
You need a fuel injection service kit to help you clean the fuel lines. A product you can rely on for this service is Autool C-100, a versatile kit that comes with different kinds of adapters to sort out EU, US, and Asian vehicles.
The Autocool C-100 will work with gasoline injectors, and it is relatively easy to use.
How Much Should Fuel Induction Service Cost?
The price of a full fuel induction service typically ranges from $150 to $170, but it can be higher depending on the severity of carbon buildup and whether any related components need attention.
If a full induction service seems unnecessary or too expensive, you can opt for a simpler, more affordable approach using fuel injector cleaner additives. These typically cost between $20 and $40 per bottle and can be added directly to your fuel tank.
While these additives can help clean fuel injectors and other components to some extent, they aren’t as thorough as a professional fuel induction service. You can use these cleaners every 5,000 to 10,000 miles as a preventative measure.
Ultimately, a professional fuel induction service provides the most comprehensive cleaning of the entire fuel and air intake system, offering the best chance of restoring optimal performance and fuel efficiency in the long run.
