Abstract
Methods and systems for controlling an engine are provided. In some examples, the engine has at least a cylinder and a compression device coupled to an intake of the engine, and the method includes, during engine re-start operation of an engine idle-stop condition, commencing combustion in the cylinder from a non-combusting condition, the combustion in a two-stroke combustion cycle of the cylinder. However, in some examples, at least partially electrically powered boosting operation may also be used to extend the two-stroke operation during a start.
