Question: Fuel injection in single cylinder, 4 stroke cycle C.l engine running at 650rp.m takes place through a single orfice nozzle and occupies28 of crank travel.

Fuel injection in single cylinder, 4 stroke cycle C.l engine running at 650rp.m
takes place through a single orfice nozzle and occupies28º of crank travel. The fuel consumption of the engine 2.2 kg /hour and the fuel used has a specific gravity of 0.875. If injection pressure is 150 bar and the combustion chamber pressure 32bar estimate the volume of fuel injected per cycle and
the diameter of the orifice. Take coefficient of discharge of orifice= 0.88
