EFI Engine:
EFI is the latest technology used in vehicles, like the old cars that were sample cars, had carburetor engines that ran without computers and sensors
The difference between an EFI engine and a simple engine is that the EFI engine is computerized. It has a computer installed and different sensors. The job of the computer is to give commands to these sensors and the job of these sensors is to maintain the complete settings of the vehicle.
For example, there are injectors that work for fuel, and the simple vehicles that used to have carburetors that used to make manual adjustments. But in computerized vehicles, this is what happens: there is a map sensor. In addition, there are injectors that are running on the command of the computer.
Manuals cannot adjust them. If there is even one connection back and forth, the vehicle will start emitting black smoke and the vehicle will not come to its settings.
plugs:
First of all, the car’s spark plugs have to be cleaned and then they are checked to see what the issue is with the plugs and how much life they have. To check the spark plugs, there is a machine to check the spark.
If the plugs in the engine are missing spark or the spark is slow, then the spark plugs you have are bad. In this case, you will have to change the plugs to improve the performance of your car.
There are plugs from different companies that are used in cars of different companies, such as the plugs used in Toyota cars are Denso Radium plugs, or the old models use Denso simple plugs. Apart from that, if you talk about Nissan, Suzuki, Honda, then they use NG plugs, and the German cars have Bosch plugs.
coils :
This is the job of the coil, which is to provide spark to the coils installed in the engine. In this case, if the coil is good, the current it has will be powerful, then the coils will provide the correct current to the engine.
If the spark plug is low, then the car will mess up, the fuel condition will become rich and it will start giving black smoke, the starting will be treble and the car will give a picture. The main thing in tuning is also to check the coil, see its condition, if it is damaged, then replace it,
if it looks completely clear, then check its spark current, if its current is perfect, then leave the coil as it is.
Injectors :
The job of the injector is to spray the petrol in the EFI engine. In old cars, the carburetor had a jet that provided fuel to the engine. That technology was old, while in the latest technology, the EFI engine has an injector that provides petrol to the engine of the vehicle, one by one.
The injector runs on the pulse of the computer. When your sensors are working properly, the injector throw is in proportion to the proper RPM. If there is an issue with your sensors or your ECU is having problems, the petrol throw is higher and in that case the vehicle
Black starts the engine, causing your fuel to reach the limit and the car to run on petrol.
map sensor:
The job of the MAP sensor is to note how much fuel and air are going into the engine. If the MAP sensor is working properly, then the fuel link is running in the right condition, meaning that the engine is providing equal amounts of air and fuel. By noting this, it tells the computer
how much flushing to do and how much injector throw to do. If the MAP sensor is working properly, then the fuel link is running in the right condition.
If the sensor no longer works properly, either more air will go into the engine or more fuel will go into the engine, in which case the car will run heavy and start emitting black smoke. The car may also have a misfire, start up trouble, and the car will start knocking.
The MAP sensor has been designed to check its own fuel system and send a signal to the regular computer to see how much fuel is going into the engine.
Oxygen Sensor :
The location of the oxygen sensor is inside the exhaust. In many vehicles, there is only one oxygen sensor, while in some vehicles there are two, and in some vehicles there are four or eight.
Its job is to note the fuel coming out of the injectors and give a signal to the computer about how much petrol is in the engine of the car.
If the fuel is going too much, it gives a signal to the computer and the computer reduces the flow of the injector and goes into a fuel lean
condition. If it is damaged, then even in this case the car starts giving black smoke. The car starts running full and it has ash in it.
