EXAMPLE PROBLEM 2-1 John's automobile has a three-liter SI V6 engine that operates on a four-stroke cycle at 3600 RPM. The compression ratio is 9.5, the length of connecting rods is 16.6 cm, and the engine is square (BS). At this speed, combustion ends at 20° aTDC. Calculate: 1. cylinder bore and stroke length 2. average piston speed 3. clearance volume of one cylinder 4. piston speed at the end of combustion 5. distance the piston has traveled from TDC at the end of combustion 6. volume in the combustion chamber at the end of combustion
