MPFI systems provide better
Most petrol engines in operation today have multi-point fuel injection systems in place, this means that each individual cylinder has its own fuel injector. Fuel is delivered just above the intake valve in the intake manifold, rather than in single-point fuel injection, which would have one injector in the throttle body. This is an evolution of the single-point injection system.

Most fuel-injection systems are closed loop, which means that any fuel sent to the injectors and not used in the engine will be returned to the fuel tank. See Figure 29–1. Fuel Pump The electric fuel pump delivers fuel from the tank to the system and develops fuel pressure. See Fig-ure 29–2.The pump is usually located inside the fuel tank, where it is cooled by the surrounding fuel. Many
In technical terms, PGM-FI is an n-alpha mapped injection system. That means the basic variables are the engine speed (n) and the throttle angle (alpha). Based mainly on these two measurements, the system looks to its fuel mapping for the fuel delivery figure corresponding to the n and alpha of the moment. Next, the engine makes adjustments as needed to this basic fuel delivery figure – tales of graces f pdf guide Single-point injection was a first step before the more complex multi-point systems came about. Not as precise as the systems that have evolved, TBI metered fuel better than a carburetor and was less expensive and easier to service.

Gradually, as new engines were designed, throttle body fuel injection was replaced by multi-port fuel injection (also known as port, multi-point or sequential fuel injection). These systems have a fuel injector for each cylinder, usually located so that they spray right at the intake valve. These systems provide more accurate fuel metering and quicker response.
Fuel injection is a method or system for admitting fuel into the internal combustion engine. From early 1940s many injection system like single-point injection, continuous injection are introduced in the market by the different companies.
Some cars have multi-point fuel injection where each cylinder is fed by its own injector. This is complex and can be expensive. It’s more common to have single-point injection where a single injector feeds all the cylinders, or to have one injector to every two cylinders.
