A PT injector is provided at each engine cylinder to spray the fuel into the combustionchambers. PT injectors are of the unit type and are operated mechanically by a plunger return spring and arocker arm mechanism operating off the camshaft.

There are four phases of injector operation, which are as follows:

Metering
The plunger is just beginning to move downward and the engine is on the beginning of the compression stroke. The fuel is trapped in the cup, the check ball stops the fuel flowing backwards, and fuel begins to be pressurized. The excess fuel flows around the lower annular ring, up the barrel, and is trapped there.

Pre-injection
The plunger is almost all the way down, the engine is almost at the end of the compression stroke, and the fuel is being pressurized by the plunger.

Injection
The plunger is almost all the way down, the fuel injected out the eight orifices, and the engine is on the end of the compression stroke.

Purging
The plunger is all the way down, injection is complete, and the fuel is flowing into the injector, around the lower annular groove, up a drilled passageway in the barrel, around the upper annular groove, and out through the fuel drain. The cylinder is on the power stroke. During the exhaust stroke, the plunger moves up and waits to begin the cycle all over.

Proper injector adjustment and maintenance will ensure a smooth running engine as long as the following factors are met:
1. Adequate fuel delivery pressure from the fuel pump to the fuel manifold.
2. Selection of the proper sizes of balance and metering orifices.
3.The length of time that the metering orifice is uncovered by the upward moving injector plunger.
