Piston Motion Calculation

The piston motion calculation indicates piston velocity, piston acceleration, piston position, cylinder volume, rod/bore angle, and rod/crank angle at various crankshaft positions. The calculation features an adjustable step size, so you can view the results at any desired increment, from 1 degree to 90 degrees. Also shown are average piston speed, rod/stroke ratio, stroke/rod ratio, and crankshaft angular velocity.

Piston Speed Calculation

Calculates piston velocity, piston acceleration, piston position, and cylinder volume based on stroke length, connecting rod length, cylinder bore, and engine speed. Graphs are provided so you can view the piston speed, acceleration, and position as they change during crankshaft rotation in a graphical form.
