A four-cylinder four-stroke engine (100 mm bore and 120 mm stroke) runs at 1800 rpm mean speed with 0.9 MPa indicated mean effective pressure (IMEP).
The flywheel constant (ratio of the energy fluctuation to the indicated work per crankshaft revolution) is 0.30. All other losses are neglected.
For an allowable speed fluctuation of \(\pm 1\%\) about the mean, the required flywheel mass moment of inertia (in \(kg.m^2\)) is ________. (Rounded off to two decimal places)
(Take \(\pi = 3.14\))
