Abstract
A modular internal combustion engine (10) comprising a cam crank assembly (75) having a cam crank (74), an intake cam (90) and an exhaust cam (92), the cam crank (74) having a piston stroke guide pattern (76) to control the stroke motion profile of the piston (70), which can be expanded by replacing the crank shaft (22) with a longer crank shaft (22), and installing a supplemental engine block (18) with a supplemental cam crank assembly (75).
