5-1.  A five-cylinder,  four-stroke  cycle SI engine has a compression  ratio Tc  = 11:1,  bore B = 5.52 cm, stroke S = 5.72 cm, and connecting rod length T = 11.00 cm. Cylinder inlet conditions are 63°C and 92 kPa. The  intake valve closes at 41° aBDC and the spark plug
is fired at'1:5°bTDC.
Calculate: (a) Temperature and pressure in the cylinder at ignition, assuming  Otto cycle analysis (i.e., assume the intake valve closes at BDC and ignition is at TDC). [K, kPa]
(b)Â Â Effective compression ratio (i.e., actual compression of the air-fuel
mixture before  ignition).
(c)Â Â Â Actual temperature and pressure in the cylinder at ignition. [K, kPa]
