Fuel Induction Service: All that you need to Know

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?

To understand the fuel induction process, we will look at how the engine operates at the primary level. 

Here, we look at engine combustion, which involves air intake to burn fuel and initiate pistons’ movement, subsequently, the transfer of motion to other car parts. 

The throttle body is an essential mechanism in combustion engines, regulating the entry of fuel or air into the combustion chamber.

The vehicle’s computer unit controls the throttle mechanism to ensure the right proportions of air and fuel. It directly links to the acceleration pedal, and this mechanism will let in air to the chamber depending on the fuel amount. The air-fuel mixture burns in the engine every time the car starts, and over time, there will be carbon traces in the engine as a remnant of the unburned fuel. The throttle and fuel injectors are some of the parts prone to carbon build-up and can lead to some issues like the gas smell inside the car. The check engine light can also turn on to indicate that your engine has a problem and you need to check it.

In the face of such an issue, you need to look for a fuel induction service near me to lead you to the right professional who will deal with the problem after proper diagnosis. The maintenance process involves the intake manifold and throttle body cleaning to clear the carbon buildup and have your engine in great shape.

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.

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.

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.

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.

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.

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.

Excess Emissions

Another pointer that you may need 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.  

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.

How to Do a Fuel Induction Service

If you have dirt in your engine system, the typical move is to go to a reputable mechanic to fix the issue. However, sometimes you want to get your hands dirty and take the task head-on. If you’re going to solve this issue at home, this guide will show you how to do a fuel induction for an engine restore and rejuvenation process.

Step 1: Cleaning the Throttle Body

You should have your fuel induction service kit containing materials like a cleaner, a rug, and general mechanics tools like screwdrivers and pliers to access some engine bay areas. The first step in this maintenance practice is cleaning the throttle body. Disconnect the air duct from the throttle body and clean it using your cleaner and the rug. Ensure you eliminate every trace of carbon on this engine part, leaving it with no hint of grime. You may also use compressed air for better results.

Step 2: Focus On Upper Cylinders And Intake Valves

With your throttle body clean, you now shift your focus to the upper cylinders and intake valves. Introduce your cleaning agent to the intake manifold, where the cleaner will attach to the intake valves. The cleaner will help break down the accumulated carbon and expel it from the exhaust pipe system, leaving you with clean parts.

In case you are not sure of how to pull the process, it is better to leave it to a professional as you may damage the car engine. You should also add fuel tank additives, which help clean the injector valves and boost the driving performance.

How Often Is A Fuel Induction Service Needed?

A fuel induction service does not need to be frequent, though it is recommendable to go for the service after 60000 miles. You can go for the induction on top of other maintenance activities like an oil change. The frequency of the induction service also depends on the state of the car. Some models, especially the older ones, may have faulty systems, and they may need the service more regularly for the engine to perform to its best.

Fuel induction service Reddit discussions opine that you can go for this service before the 60000-mile mark. It is more of a preventive measure, especially if you experience signs of a failing engine. This car maintenance process has many benefits to your car, such as being an effective way to clean the fuel tank. Here are other benefits you gain from the induction.

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 a 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.
