Design a family of vee engines to be built on the same assembly line. They must all have the same vee angle and use the same pistons, connecting rods, and strokes. Their crankshafts can each be different. Four configurations are needed: vee four, vee six, vee eight, and vee ten. All will have the same single-cylinder displacement of 0.5 liters. Optimize the single-cylinder configuration from which the multicylinder engines will be constructed for bore/stroke ratio and conrod crank ratio. Then assemble this cylinder design into the above configurations. Find the best compromise of vee angle to provide a good mix of balance and even firing in all engines.
