The following events occur during the power stroke for any of the cylinders of the 6.5L V8 turbo diesel engine (refer to Figure 1-7):
• At the end of the compression stroke, the fuel injection pump (operated at camshaft speed by a gearset) delivers fuel through a pipe to a nozzle positioned in the combustion area of the cylinder.
• The nozzle opens, spraying fuel into the hot, swirling air in the pre-combustion chamber.
• The heated air/fuel mixture achieves combustion, and expanding gases push the connecting rod/piston for the cylinder in a downward direction.
• The connecting rod/piston provides rotating force for the crankshaft.
