Abstract: The objective of this study, is to present the experimental results for diesel engine power calculation based on air flow through engine from test flow of engine cylinder head using Superflow Flowbench SF-1020. In the SuperFlow Flowbench for four-cycle engine testing, air is drawn in through the cylinder head into the machine, through the air pump and exits through the vents at each side of the flow bench. A flow test in SuperFlow Flowbench consists of blowing or sucking air through a cylinder head or other component at a constant test pressure then the flow rate is measured at various valve lift. In this experiment, test pressure is setting at 1651, 1397, 1143, 889 and 635 of mm H2O, then the valve lifts in setting at 0.05, 0.1, 0.15, 0.2 and 0.25 of L/D ratio in every test pressures. The experiment and the calculations results are shown in table and figure in this study. The result shown that increasing of the valve lift and test pressure are positive correlation to increase the air flow through engine, engine power and engine speed.
