ABSTRACT:
A variable compression ratio internal combustion engine is programmably configured to operate in a plurality of compression ratios. Internal combustion engines with electronically controlled engine components that include electronic valve operation are programmed to operate individual engine cylinders with component states and stoke sequences that provide variable compression ratios by creation of a virtual cylinder within a physical cylinder. Cylinder volume dictates maximum compression ratio, which acts as a ceiling for the variable compression ratio that can be provided.
