EXCERPT:
Inlet air passes through the air cleaner into the air inlet (8) of the turbocharger compressor wheel (10).
The turbocharger will supply more volume of air into the engine. This compressing of the air is referred to as boost. The compressing of air causes the air temperature to rise to about 204 °C (400 °F). As the air flows through the aftercooler (7) the temperature of the compressed air lowers to about 46 °C (115 °F).
Cooling of the inlet air causes the air to become more dense. This increases combustion efficiency and this increases horsepower output.
From the aftercooler, air enters the inlet manifold (3). Air flow from the inlet manifold (3) into the cylinders is controlled by inlet valves (1). There are two inlet valves and two exhaust valves (2) for each cylinder. The inlet valves open at the top center position before the piston moves toward the bottom center position. This is called the inlet stroke. When the inlet valves open, cooled compressed air from the inlet port enters the cylinder. The inlet valves close as the piston reaches the bottom center position.
The piston begins to travel back to the top center position on the compression stroke. The air in the cylinder is compressed to a very high temperature. When the piston is near the end of the compression stroke, fuel is injected into the cylinder and mixes with the air. This causes combustion to start in the cylinder. Once combustion starts, the combustion force pushes the piston toward the bottom center position. This is called the power stroke. The exhaust valves open when the piston moves toward the bottom center position and the exhaust gases are pushed through the exhaust port into exhaust manifold (4) as the piston travels toward top center on the exhaust stroke. The exhaust valves close and the cycle starts again. The complete cycle consists of four strokes:

EXCERPT:
Fuel Injection Timing and Delivery
The ECM controls the injected fuel amount by varying the signals to the unit injectors. The unit injectors will inject fuel only if the unit injector solenoid is energized. The ECM sends a 90 volt signal to the solenoid for energizing the solenoid. By controlling the timing of the 90 volt signal, the ECM controls injection timing. By controlling the duration of the 90 volt signal, the ECM controls the injected fuel amount.
Injection timing is determined by engine rpm, and other engine data. The ECM senses the top center position of cylinder number 1 from the signal that is provided by the engine speed sensor. The ECM decides when the injection should occur relative to the top center position. The ECM provides the signal to the unit injector at the desired time.
