1. Direct fuel injection: In this type of fuel injection, fuel is injected directly into the combustion chamber of each cylinder. This allows for more precise control over the fuel-air mixture and can result in improved fuel efficiency and performance.
2. Port fuel injection: In port fuel injection, fuel is injected into the intake port just before it enters the combustion chamber. This type of fuel injection is less precise than direct injection but is still commonly used in many vehicles.
3. Throttle body injection: Throttle body injection is a type of fuel injection where fuel is injected into the throttle body, which is located between the air filter and the intake manifold. This type of injection is less efficient than direct or port injection but is still used in some older vehicles.
4. Sequential fuel injection: Sequential fuel injection is a type of fuel injection system that delivers fuel to each cylinder individually, based on the engine's firing order. This allows for more precise control over the fuel-air mixture and can result in improved performance and fuel efficiency.
5. Multi-point fuel injection: Multi-point fuel injection is a type of fuel injection system that injects fuel into each cylinder's intake port. This type of injection is similar to port fuel injection but is more advanced and allows for more precise control over the fuel-air mixture.

1. Port Fuel Injection (PFI)
- Injectors located inside the intake ports, spraying fuel directly into the cylinder.
- Common in older vehicles and some modern cars.
2. Throttle Body Injection (TBI)
- Injectors installed in the throttle body, spraying fuel into the intake manifold.
- Simpler and less expensive than PFI, but less efficient.
3. Direct Injection (DI)
- Injectors located directly inside the cylinder, spraying fuel directly into the combustion chamber.
- More efficient and provides better power and torque.
- Can be gasoline (GDI) or diesel (CDI).
4. Fuel Rail Injection (EFI)
- Similar to PFI, but uses a common fuel rail to supply fuel to multiple injectors.
- Allows for more precise fuel metering and control.
5. Sequential Fuel Injection (SFI)
- Injectors fire in sequence with the intake valves, allowing for better fuel distribution.
- Provides more precise control over fuel injection timing.
6. Multi-Point Fuel Injection (MPFI)
- A combination of PFI and EFI, with multiple injectors located in each intake port.
- Provides optimal fuel distribution and improved engine performance.
7. Electronic Fuel Injection (EFI)
- An umbrella term for any fuel injection system that uses an electronic control unit (ECU) to manage fuel delivery.
- Includes all of the above types of fuel injection.
8. Common Rail Direct Injection (CRDI)
- A specific type of DI system used in diesel engines.
- Uses a common fuel rail to supply high-pressure fuel to multiple injectors.
- Provides very precise fuel metering and control.
- Injectors located inside the intake ports, spraying fuel directly into the cylinder.
- Common in older vehicles and some modern cars.
