Abstract

A valve system/method suitable for an internal combustion engine (ICE), compressor pump, vacuum pump, and/or reciprocating mechanical device is disclosed. The system/method is optimized for construction of a two-stroke ICE. The rudimentary system incorporates an intake engine block cover (IEC) and exhaust engine block cover (EEC) that enclose an intake rotary valve cylinder (IVC) and exhaust rotary valve cylinder (EVC) that control intake/exhaust flow through a respective intake rotary valve port (IVP) and an exhaust rotary valve port (EVP) into and out of a combustion cylinder that provides power to a piston and crankshaft. Intake/exhaust multi-staged valves (IMV/EMV) provide intake/exhaust flow control for the IVC/IVP and EVC/EVP. An enhanced system may include a variety of intake/exhaust port seals (IPS/EPS), forced induction/discharge (FIN/FID), centrifugal advance (CAD/ICA/ECA), and/or cooling channel spool (ICS/ECS).
