A V8, four-stroke cycle CI engine operates at 1800 RPM, using light diesel fuel at AF=24, and a volumetric efficiency of 94%. Injection timing is from 22° bTDC to 4° aTDC. Swirl ratio, as defined by Eq. (1), equals 2.8 during fuel injection.
Calculate:
(a) Time of one injection. [sec]
(b) Period of swirl (one rotation). [sec]
(c) Number of orifice holes needed in each injector, with one injector per cylinder.
