A 150-in.3, four-cylinder, four-stroke cycle, high-swirl CI engine is running at 3600 RPM. Bore and stroke are related by S = 0.95 B. During the compression stroke, the cylinder air has a swirl ratio, as defined by Eq. (6-2), of 8. Calculate: (a) Swirl tangential speed. [ft/sec] (b) Angular velocity of cylinder air using the paddle wheel model. [rev/see]

Respuesta :

Answer:

Explanation:

(a) Swirl tangential speed = 3 x MPS ( mean piston speed)

= 3 x 420.76 inch/sec = 280.51  [ft/sec]
