For a 1.6 liter 4-cylinder engine operating at wide-open throttle at 2500 RPM, the stroke/bore S/B = 1.0 and connecting rod length/crank throw, l/a = 4.

a.Estimate the time for intake, compression, combustion, power and exhaust processes for this typical engine. Describe/justify the assumptions that you make.

b.Estimate the maximum velocity in the intake port. Assume port area is 20% of piston area.

c.Estimate the average velocity of the flame as it travels across the combustion chamber. Describe and justify any assumptions that you make.
