Abstract
A method for controlling an engine having a variable valve actuator includes operating the engine in a first mode where the engine carries out spark ignition combustion of air and fuel; and changing operation to a second mode where the engine carries out homogenous charge compression ignition combustion of air and fuel. The variable valve actuator unit is adjusted in response to said change to provide a shorter valve opening or lift.
