Multi-Port-Fuel-Injection Throttle Body

The port system utilizes injectors of a different type than the throttle body injection system. The fuel/air ratio is controlled in the same manner as the TBI system. Instead of an injector mounted in a centrally located throttle body, one injector is installed above each intake port. The throttle body on the MPFI system serves only to control the amount of air passing into the system. Because each syslinder is equipped with an injector mounted emmediatly adjacent to the intake valve, much better control of the fuel/air mixture ratio is possible.
