A 3.6-liter, V6 SI engine is designed to have a maximum speed of 7000 RPM. There are two intake valves per cylinder, and valve lift equals one-fourth valve diameter. Bore and stroke are related as S= 1.06B. Design temperature of the air–fuel mixture entering the cylinders is 60°C.

Calculate:

(a) Ideal theoretical valve diameter. [cm]

(b) Maximum flow velocity through intake valve. [m/sec]

(c) Whether the valve diameters and bore size seem compatible
