In electronic injection, what this does are electronically controlled injection nozzles. In this way, the center injects fuel into strategic points of the engine and according to the needs of the bike in every situation. Therefore, the combustion is much more efficient, which avoids wasting fuel.

The electronic injection system also helps to reduce the emission of polluting gases, making the option more ecological. In addition, it also minimizes the need for maintenance and increases the life span of the various components of the bike. Find out more about the benefits of this system.

Advantages and disadvantages of electronic injection in motorcycles

As we have already shown above, electronic fuel injection is a more environmentally friendly and economical option for motorcycles. But in addition, this system has other advantages over the carburetor. Check it out!

# 1 Improve engine performance

The first advantage is related to the functioning of the systems. In the carburetor, the mixing of air and fuel takes place via manual actuators in the combustion chamber. For this reason, there is little precision in this process.
In the case of electronic injection, sensors are used to measure the amount of fuel injected and the air pressure. Therefore, in this system, the engine operation is more efficient.

# 2 Has a longer shelf life

One of the biggest problems with carburetor engines is that, after a while, they need frequent repairs. This does not happen with electronic injection.

In addition to having a longer duration, electronic injection allows the mechanic to diagnose the system. This way you can assess the situation and reschedule the form in case of problems.

Also, the need to replace the system is rare. This feature makes the bike much more reliable for everyday use or for long journeys.

# 3 Greater economy and performance

As mentioned above, electronic injection ensures greater fuel economy. However, the mixture of fuel and air metered according to the needs of the vehicle also offers other advantages.

This system improves also performance and guarantees more power to the bike. This is because the engine has more adequate power and according to the speed and torque required by the ground, for example.

However, despite the many advantages, the electronic injection system can also have problems. One of the disadvantages is related to maintenance.

This is because the carburetor is easy to maintain, often done at home. In an electronic system, however, it must be performed by a specialized professional and with the appropriate equipment.

For this reason, electronic fuel injection also ends up being more expensive than a carburetor. In addition, attention must also be paid to the quality of the fuel used. This is because the use of substandard fuel can clog the fuel injectors.

This problem can cause an incorrect reading of the sensors, causing an increase in consumption and a decrease in the power of the motorcycle.

Main differences between the available systems

Today it is possible to find different electronic injection systems for motorcycles. After all, over the years, they have undergone a lot of improvements. Therefore, it is necessary to know the available systems and the differentials of each.

# 1 Analog or digital systems

Older systems had analog fuel injection. In other words, the injection routines were planned in advance and not optimized for the situation.

Therefore, over the years, digital power systems have gained ground. It is this type of system that counts the sensors to monitor and increase the efficiency of the injection according to the needs of the motorcycle.

# 2 Fuel injection mode

The injection nozzles have three opening modes: intermittent, semi-sequential or sequential. In the first case, all the nozzles inject fuel at the same time and only one cylinder at a time delivers fuel to the engine.
However, the fuel consumption was still high, so it was replaced by the semi-sequential system. In this case, two nozzles work simultaneously.
In the sequential system, a central unit controls each injection nozzle individually. In this way the fuel is injected in the necessary time and with greater efficiency. That’s why it guarantees better fuel economy.

# 3 Number of injection nozzles

Another difference between the systems is the number of fuel injection nozzles: single-point and multi-point. The first has a single injection point, which caused a considerable waste of fuel.

For this reason it has been replaced by multipoint injection. This system works with an injection nozzle for each cylinder.

In this way, direct injection is carried out in the intake valve, leaving the manifold only for air circulation. Furthermore, the larger diameter of the transmission manifold also favors the power of the engine.

Since it is considered a new system on the market, some problems in electronic injection are new to mechanics. Therefore, it is necessary to know how to identify when something is not going well in order to fix it as soon as possible.

Main problems and diagnostics in the electronic injection system

When there are problems with the electronic fuel injection system of the motorcycle, it is normal for the warning light to come on permanently. The two most common problems are related to sensors or engine failure.

Sensors must work precisely to meet the needs of the vehicle in every situation. Otherwise, they could misinterpret the driving style and needs of the driver.

When the problem is related to engine failure, it is a sign that there is something wrong with the combustion system. In these cases, there could be anything from a disconnected wire in the ignition to a defect in the electrical part of the bike.

In both cases it is necessary to use the proper equipment to identify the problem and carry out the repair correctly. Therefore, it is very important to know how to identify the problem to avoid bigger problems. Some common signs are:

# 1 Difficulty in the game

It is common for motorcycles to have difficulty starting on very cold days. But if this happens on hot days, it could indicate a problem.

# 2 Inactive fault

In injection motorcycles, the component responsible for fueling works electronically. Therefore, when there is a problem, it can have an erratic idle speed and even drown when it has a defect.
The motorcycle check-up is therefore essential to avoid any problems.

# 3 Excessive fuel consumption

Another factor that could indicate that something is wrong with your motorcycle is excessive fuel consumption. This problem can be caused by several factors and, if not investigated as soon as possible, can worsen over time.

Therefore, it is very important to pay attention to the signs that your motorcycle presents so that they do not become bigger problems.

Now that you know all about electronic injection and how to diagnose the main problems, why not invest in a course in this area?
