A 3630 New Holland Tractor has a four-cylinder four-stroke cycle engine. It has a cylinder bore of 8.89 cm, a stroke of 12.7 cm, and a compression ratio of 16.5:1. The tractor can develop 32 hp that can be used for field operation at 2000 rpm. Find the piston displacement (cubic centimeter) of the tractor engine, the total displacement volume (liters) of the tractor engine, the stroke to bore ratio and the piston speed (m/min) of the tractor engine.
