ABSTRACT:
A method to control injection timing for an internal combustion engine having a plurality of injectors in at least a cylinder, the method comprising of boosting intake air delivered to the engine, directly injecting a fuel to at least a cylinder of an internal combustion engine, adjusting each of a timing and number of direct injections for a cylinder cycle as an alcohol amount in the fuel varies, where said adjusting includes advancing direct injection timing relative to intake valve timing as said alcohol amount increases.
