Abstract
The present disclosure is directed at the control of an effective compression ratio setting in an engine which may use a variety of fuels or fuel blends. The effective compression ratio may be selected based upon information from a fuel sensor and stored information regarding the detected fuel composition. The effective compression ratio may be adjusted for a selected cylinder by intake or exhaust valve timing.
