2. An automobile that has a 2-liter Inline 4-cylinder SI engine operates on a four-stroke cycle and is being tested at 2800 rpm. The compression ratio of the engine is = 8.5, the length of the connecting rods is = 15 cm and the engine is referred to as "square", which means that bore = stroke (b=s). At this speed, the combustion process ends at 20 after top-dead-center (ATDC). Calculate: (i) The cylinder bore (b) and stroke (s); (ii) The average piston speed; (iii) The clearance volume (of one cylinder); (iv) The distance the piston has travelled from TDC at the end of combustion; (v) The piston speed at the end of combustion; (vi) The volume in the combustion chamber at the end of combustion.
