MFI systems are typically used in gasoline engines, but can also be used in diesel engines. In a gasoline engine, the fuel injectors are mounted in the intake manifold. In a diesel engine, the fuel injectors are mounted in the cylinder head.
The fuel injectors are controlled by the engine's electronic control unit (ECU). The ECU uses a variety of sensors to determine the engine's operating conditions and then calculates the amount of fuel that needs to be injected into each cylinder.
MFI systems are more expensive than single-point fuel injection systems, but they offer better performance and fuel economy.
Here are some of the advantages of MFI systems:
* Improved fuel economy
* Increased power and torque
* Reduced emissions
* Smoother engine operation
* Better cold-starting
Here are some of the disadvantages of MFI systems:
* More expensive than single-point fuel injection systems
* More complex design
* More difficult to maintain
Overall, MFI systems offer a number of advantages over single-point fuel injection systems. They can improve fuel economy, performance, and emissions. However, they are more expensive and complex than single-point fuel injection systems.
