An eight cylinder, four stroke/cycle, single acting diesel engine has a 650 mm bore and a 1400 mm stroke. What will be the developed indicated metric horsepower if the average mean effective pressure is 30 kg/cm2 at a speed of 100 RPM?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 9,111 kW
Indicated metric horsepower for a four-stroke engine incorporates bore area, stroke length, MEP, cylinder count, and RPM. For an 8-cylinder, 650mm bore, 1400mm stroke engine at 30 kg/cm² MEP and 100 RPM, standard conversion yields approximately 9,111 kW of indicated power.
