Multi-Point Fuel Injection (MPFI) is an advanced fuel delivery system for gasoline engines.
Each cylinder in an MPFI system is equipped with its own individual fuel injector.
These injectors are positioned close to the intake port of each cylinder.
By injecting fuel directly at the intake port, it effectively atomizes with the incoming air, creating a homogenous air-fuel mixture.
This optimization leads to enhanced combustion, increased power, better fuel economy, and lower emissions.
In contrast to a carburetor, which blends fuel and air within the intake manifold, MPFI provides precise fuel delivery to each cylinder's intake.
The outlet port is designated for exhaust, not intake.
Consequently, the accurate response is intake port.
