Electronic Fuel Injection Conversion

Fuel injection is present in the internal combustion engine for introducing fuel by using an injection. The diesel automobiles have fuel injection system by design and petrol automobiles use gasoline direct injection system. Petrol automobiles had mechanical injections which had certain limitations. This was the reason electronic fuel injection was used which allowed optimal use of fuel in an automobile’s engine that allowed it to operate at any condition.

A contemporary injection system which runs on gasoline utilizes pressure generated by the electric fuel pump and in this way the fuel is pushed into the engine. A classic car that used carburetor in the engine requires the hottest upgrade which is electronic fuel injection conversion. There are many advantages of getting the fuel injection as an upgrade for your automobile.

Things to consider before conversion

1. Air quality:

Before you consider electronic fuel injection conversion, you need to understand that the barometric pressure increases, and temperature decrease with air contracting and its mass increasing and the vice versa. So, you need to understand that air quality influences internal combustion engine. It is vital that you consider where you live before you consider for conversion of fuel injection system.

2. Carburetor limitation:

Carburetors are installed in older cars and are calibrated by professionals. You just need to tune it and the performance it provides is satisfactory for many. However, tuning is not an easy job and requires you to consider a lot of factors. With EFI you don’t have to worry about tuning to get better performance.

3. Air fuel ratio:

A very important factor to consider before you go for conversion or stay with carburetor is air-fuel ratio. It is the ratio between the amounts of air entering the engine to fuel metered.

Things that will help conversion

When you are planning on electronic fuel injection conversion from the old carburetor, you must understand that you will be facing a lot of problems. Although nothing is complicated, but things are plenty to deal with and experienced people can help to solve these problems.

1. Accelerator pad:

While converting the system, the original cable operated throttle pad need to be replaced with electronically compatible pedal. The sensors attached can tell the engine controller to open the throttle to a certain limit when the pedal is pressed.

2. Wiring harness and Engine control module:

Many thinks about building a system from scratch and they try hard to create appropriate control module. However, there are control module or harness kits available which have almost everything including controller, harness, throttle pad, oxygen sensors etc. The wiring harness is needed to connect engine control module to injection systems and other related sensors.

3. Fuel pump:

You need a high-pressure fuel pump for new EFI systems. There are various options available in the market. You can choose between in-tank and external inline pump. In-tank is considered ideal for automobiles as it keeps vehicle cooler because of its immersion.

4. Mass airflow sensor installation:

Proper positioning of mass airflow sensors is very vital while making conversion to EFI.

5. Oxygen sensor installation:

You need to install oxygen sensors when you are converting to fuel injections. Oxygen sensors help determine optimal fuel efficiency and provide engine control module signals that is related to oxygen content in the exhaust.

6. Fuel tank and fuel return line:

You can consider many options available in the market when it comes to replace the fuel tank. Fuel return line is needed for factory style return-less fuel system for connecting fuel tank with the engine.

Getting a fuel injection system means enjoying even and consistent transient throttle response including easier cold start decreased maintenance needs better fuel efficiency etc. There is no need to have a separate mechanical choke required for vehicles with the carburetor. Stratified combustion is also possible for EFI systems. So, it is wise to consider conversion from the carburetor to EFI system.
