Fuel Injector

Fuel Injector:

The MULTEC 2 MPFI Assembly is a solenoid operated device, Controlled by an on-board computer called the "Powertrain Control Module" (PCM), that meters fuel to a single engine cylinder. The PCM energizes the solenoid (2) to open a normally closed ball valve (3). This allows fuel to flow into the top of the injector (1), past the ball valve, and through a director plate at the injector outlet. The director plate has procision holes that control fuel flow, generating a spray of finely atomized fuel at the injector tip. Fuel from the injector tip is directed at the intake valve, causing it to become further atomized and vaporized before entering the combustion chamber.

The eight digit part number (2) is identified on the fuel injector body (1). A four digit number build date code is located to the far left of the pan number.
