Engine LD Hack 1.600

Screenshots

Description

Engine Layout Definitions is an educational tool that shows how layout changes in an internal combustion engine piston-crank system will affect engine's displacement, its rated power and dynamic forces.

Engine LD gives graphical plots and lists for displacement volume vs crank angle data and dynamic forces vs crank angle data to support further spreadsheet calculations and basic finite element calculations.

Users can simulate crank rotation with a slider to see effect of selected dimensions on engine packaging.
