Patent ID: 6947830

Claim:
A programmable internal combustion engine re-configurable to operate with a given fuel from a range of combustible fuels comprising: one or more cylinder units each with expanding and contracting cylinder volume and associated stroke sequences; each cylinder unit having an intake port and an electronically controllable intake valve component having multiple states under computer control; each cylinder unit having an exhaust port and an electronically controllable exhaust valve component having multiple states under computer control; each cylinder unit having an electronic fuel injector component having multiple states under computer control; each cylinder unit having computer controlled means for igniting an air-fuel mixture in the cylinder volume, ignition means chosen from a group consisting essentially of; spark ignition, homogeneous charge compression ignition and compression ignition; a computer usable medium; a computer control system comprising computer readable program logic embodied in the computer usable medium for controlling individual cylinder units by actuation of cylinder components through programmed sequences of states and strokes providing detonation signal from fuel combustion; one or more sensors for sensing detonation signal; detonation signal computationally processed for identified parameters which are stored in computer usable media; identified parameters compared for power developed from combustion, whereby identified parameter results determine ignition method and cylinder component state sequences in re-configuring cylinder units for engine power operation using the given fuel.
