Due to several 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 an old vehicle component, the carburetor, arose. As a result, the fuel system evolved and electronic injection was created.
Another reason that motivated factories to develop electronic injection is that the automotive market was lacking this evolution. The engines that existed at the time were no longer able to meet demands such as power, fuel economy and faster engine responses.
What is electronic injection
Electronic injection was created to replace the carburetor and quickly became mandatory in all vehicles launched in Brazil. As indicated by Four Wheels article, presented at the 1988 Motor Show, the first national car with electronic injection was a Volkswagen Gol GTi. In 1990, the Santana Executive came from the same manufacturer and then Chevrolet launched the Monza MPFI and Kadett GSI.
This part is responsible for managing engine operation. In other words, all information related to injection map, ignition map, torque limiter, speed limiter, all the behavior of the car's operation is the electronic injection that is responsible.
The electronic control unit (ECU) practically controls the entire car, as if it were a brain, ranging from the air/fuel injection that is sent to the engine, to the vehicle's sound media panel.
What is your function?
It is the electronic injection that controls several engine functions, such as air pressure, fuel intake, idle speed, ignition timing and valves. All this control is carried out by an electronic integrated circuit that considers how the engine is working and adjusts everything to achieve the best performance.
What the electronic injection does is control the amount of fuel that goes into the vehicle's engine, so if, for example, you remove it, take the fuel hose and simply connect it directly to the engine, it will flood or get super accelerated (if you can somehow make it work). In short, it won't work, you will need some part that controls how much fuel goes into your engine.
Speaking of fuel, there can be neither too much nor too little. If too much fuel is sent to the engine, it will stall and become weak. If there is too little, the engine will fail, overheat and fail, so there must be a right control depending on what you accelerate and several other factors. To control all of this, electronic injection has sensors and actuators. It is important not to confuse one with the other.
Sensor x Actuator
The sensor takes information and sends it to the central unit. He doesn't act, he simply “sees” what is happening and passes the information to the center. As if he said “It’s at X temperature, it’s at Y rotation”.
The electronic injection control unit takes this information from the sensor and then decides which command to make. The sensor only senses what is happening to send the information to the central unit.
In the case of the actuator, as the name suggests, it acts. In some cases, it will move the butterfly, or pulse the nozzle, then the control unit commands some action, it will send a command to the actuator. Different from the sensor, as the sensor sends signals to the control unit and then the control unit sends the command to the actuator.
Some examples of actuators are: fuel pumps, fuel injectors, cooling fan, idle actuator.
Electronic Injection Reprogramming
With the advancement of technology within the automobile industry, new tools and services emerge to improve engine performance. These changes can provide greater power, torque and acceleration.
A remap It is nothing more than a change in the software responsible for managing the vehicle's engine. It is an adjustment of the vehicle with the intention of allowing better performance for each need.
To know everything about electronic injection reprogramming, we recommend reading this text What is electronic injection reprogramming? Where we cover everything about Remap.
A Strike Brasil is the largest authority on Remap (electronic injection reprogramming) in Latin America, with more than 50 units spread across Brazil, Bolivia and Paraguay. Our maps are developed by a specialized team of European engineers, highly trained and who follow strict quality standards.
