A 6.8-liter, in-line, eight-cylinder CI engine has a compression ratio rc = 18.5 and a crevice volume equal to 3% of the clearance volume. During the engine cycle pressure ill. the crevice volume equals combustion chamber pressure while remaining at the cylinder wall temperature of 190°C. Cylinder conditions at the start of compression are 75°C and 120 kPa, and peak pressure is 11,000 kPa. Cutoff ratio is f3 = 2.3. Calculate: (a) Crevice volume of one cylinder. [em3] (b) Percent of air-fuel mixture in the crevice volume at the end of compression. [%] (c) Percent of air-fuel mixture in the crevice volume at the end of combustion. [%]
