Engine cranking system with cylinder deactivation for a direct injection engine |
摘要 |
An engine cranking system includes fuel injectors that are associated with multiple combustion chambers of an engine. The fuel injectors include a first fuel injector that is associated with a first combustion chamber. A second fuel injector is associated with a second combustion chamber. A control module is coupled to the fuel injectors and operates the first fuel injector in a deactivated state for a first chamber cycle during cranking of said engine. The first chamber cycle includes intake and exhaust strokes and is associated with a first combustion chamber.
