Variable displacement engine starting control |
摘要 |
A system and method for controlling a variable displacement engine during cranking and starting period include a hybrid operating mode to allow intake/exhaust valve operation while preventing fuel delivery or spark, or both, to at least one subsequently deactivated cylinder or bank of cylinders during the cranking and starting period. The system and method provide advantages to starting the engine relative to either a variable displacement mode or a full activation mode.
