All About Electronic Fuel Injection System

Before we talk about the electronic fuel injection system, we need to talk about why the carburetor went off, and this system installed.

The key is to increase the efficiency of fuel consumption. Beyond that, it’s environmentally friendly, such as reducing the number of harmful gases and particles that are released into the environment through complete combustion.

Suppose a car with a carburetor goes down a long ramp. Then we need an engine-resistant force. But we can’t control the airflow through the carburetor. When the throttle valve is fully closed, there is little room for air to flow. Here is a vacuum in the inlet manifold. Fuel flows through the idle circuit of the carburetor. They burn (if the carburetor is defective), and the same thing happens when brakes are applied. These are completely unnecessary fuel burns.

Here is the ability to remove these things in the EFI system. Here’s a little bit of milk that feels good in our pocket.

Engine Efficiency Or Energy Conversion An Engine in Fuel injection system

Chemical Energy > thermal Energy > kinetic Energy

The fuel we use contains carbon and hydrogen, which we call hydrocarbons. The molecular formula of petrol is not exactly what we call a CxHy because it is a mixture. We know that oxygen is needed to burn just enough. Here we call this triangle the fire triangle in fuel injection system.

Fire Triangle Facts – fuel injection system

How does fire triangle work?
What is meant by the fire triangle?
What are the four elements of fire?
When all 3 element of the fire triangle combine what can occur?

• Oxygen
• Heat
• Fuel

Here we can get full combustion if these three elements are on fire at the right rate and on time. The result is heat, carbon dioxide, and water. This is what we are trying to achieve.

CxHy + O2-> CO2 + H2O

This is the complete combustion equation. Only the water and carbon dioxide are emitted into the final atmosphere. So, God, there’s no problem. Here’s how to combine this gas to 14.7: 1 gas-to-fuel ratio. For example, 1 kg of fuel requires 14.7 kg of gas.

But when we go to work with an engine, we have to work under different conditions. Let’s take an example.

• Big mountain, the driver only
• Big Mountain 2500 kg loading weight
• 80 kmph in a fast plain
• 80 kmph Fast loading weight 5000kg

These are just four examples. Let’s see how the engine’s weight can be changed or the power to be supplied.

• A mountain requires more power than a plain because there is no load.
• Now there are loads more Energy than before.
• Just a little time for the engine to power a little.
• The higher the speed, the higher the load.

Here all these things cannot be done in a theoretical ratio of 14.7: 1.

Engine speed and Engine Torque – fuel injection system

Here’s a good look at this graph. You’ll understand what I said above. So we need to use all of these in order to take advantage of this engine. The pollution of the environment by the need for more power is not possible. NO (x) by reacting with nitrogen and oxygen when power is low, and fuel is not available. Pollution is also pollution. We have to fix this. Here is an EGR system in fuel injection system.

Engine Control System (Petrol)

Observe this graph closely. You will realize that if we take more power, we need more fuel and less power at low power.
If you can understand this graph and change your driving style, you can save fuel. Keep an eye on that too.

Now we know the factors that make combustion complete combustion. To do this, we need data providers, we need to analyze the data that comes in, we need two command executors, and we need to figure out what the people we’re commanding are doing. Whatever we do, we have those who are not doing what they given.

Here’s a little look at this diagram of fuel injection system

These include the sensors, the data engineer control unit, and the command implementers called actuators.

Let’s find out how to get the combustion feed. It uses data from Mass Air Flow Sensor, Manifold absolute pressure sensor, intake air temperature sensor, and Barometric pressure sensor.

The driving conditions of the vehicle are identified by the way the driver handles the vehicle. That means the accelerator is trampled. The power of the ECU is determined by the amount of traction on the engine’s RPM and the accelerator pedal and the mass airflow and map sensor data. Or what’s the situation. The ECU can’t think, and the manufacturer has provided the program, and he delivers.

It also takes the engine’s coolant temperature sensor, the engine’s rotation speed, and the cam angle sensor. Putting a spark in the right place will ultimately separate the combustion. Here are some of the basics needed to get the engine up and running.
