A 6.8-liter, in-line, eight-cylinder CI engine has a compression ratio and a crevice volume equal to 3% of the clearance volume. During the engine cycle, pressure in 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. Cut-off ratio is
=2.3.

Calculate:

(a) Crevice volume of one cylinder. [cm³]

(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. [%]
