The automotive sector has been gaining new solutions and improving technologies over many years. One of these major developments was the replacement of the carburetor by electronic injection.
In the same way that other components of a vehicle were forced to evolve and keep up with technological advances, the same happened with the carburetor.
Due to the various programs and agreements to control vehicle emission of gases into the atmosphere that many countries have signed and established over the years, the need to replace this old vehicle component, the carburetor, arose.
Firstly, there was the emergence of double-stage, electronic carburetors and then there was a greater evolution in the fuel system and electronic injection was created.
In this text we will explain the difference between a carburetor and electronic injection to eliminate doubts once and for all.
Carburetor
The carburetor is the main mechanical component of a vehicle's fuel system. Its main function was to create the air/fuel mixture and its dosage in internal combustion engines. This mixture was then sent to the engine in the right amount for the engine's conditions so that it had good performance and adequate consumption.
How the carburetor works
The air that is sucked in by the piston passes at high speed through the diffuser and sucks in the fuel that comes from the tank. The throttle body (TBI) is directly connected to the accelerator pedal, this is the part that controls the amount of air/fuel mixture that the engine needs.
Electronic injection
Electronic injection is responsible for managing engine operation. It controls functions such as air pressure, fuel intake, idle speed, ignition timing and valves. All of this is carried out by an electronic integrated circuit that considers how the engine is working and adjusts everything to achieve the vehicle's best performance.
Unlike the carburetor, to control all this the electronic injection does not do it mechanically, it has sensors and actuators. If you want to know more about how these sensors and actuators work, we recommend reading the post Electronic injection – What is its function and how does it work? where we explain exactly how these two components act in the vehicle.
Do you already understand the difference between a carburetor and electronic injection?
The first and main difference between a carburetor and electronic injection is that in the carburetor the air/fuel mixture is carried out using manual actuators. These actuators are not as precise as an electronic injection that has sensors to dose the air/fuel mixture.
The maintenance of these two components is also a big difference factor. The carburetor, after a certain period of use, required frequent repairs.
Furthermore, electronic injection ended up making life easier for the mechanic, who today can quickly carry out a complete reading of the car and diagnose the source of the problem in the vehicle. With equipment, the mechanic can see the diagnosis and reprogram the electronic injection module in case of failures or problems.
More power and torque
As it is an electronic component, it is also possible to remap (electronic injection reprogramming) for those who want more performance in their car. Understand what it is, the advantages and why it is a good deal to reprogram electronic injection by reading the text in the link, where we show how to achieve greater power, torque and acceleration.
