GM 6.5L V8 – Intake Stroke

The following events occur during the intake stroke for any of the cylinders of the 6.5L V8 turbo diesel engine (refer to Figure 1-5):
• At the end of the exhaust stroke, the rotating crankshaft also rotates the camshaft and the intake lobe for the cylinder pushes a hydraulic roller lifter upward.
• The lifter operates a rocker arm, using a hollow push rod, which pushes open the intake valve.
• As the crankshaft rotates, it pulls the connecting rod/piston for the cylinder in a downward direction.
• The action of the piston and the turbocharger causes the air induction system to allow air (and crankcase gases) to move into the combustion area of the cylinder.
