For this two-part problem we're going to use my 4.3L Vortec V6 in this example. Data: The engine's crankshaft is rotating at 1000 RPM. The Piston Stroke is 3.48 inches. To simplify the problem somewhat, neglect any connecting rod angles (for now). The usual Piston Stroke Length Ls and crank radius r, as in Ls = 2*r applies. Q1: What is the maximum velocity of any one of the pistons in Inches/Sec.? Q2: At what position in the cylinder will the piston attain its maximum velocity? This Question is not open to any Engineering Discipline or Physics Discipline.
