Summary: | Methods and systems are provided for improving engine startability during cold-start conditions, when operating with gasoline fuels, alcohol fuels, or blended fuels. In one example, a method of engine cold-start control may include initiating fuel injection for cylinder combustion with manifold pressure lowered via intake throttle adjustments. The manifold pressure is lowered based on an optimization between cylinder charge reduction and improved fuel boiling at the lower pressure. |
