FIELD: internal combustion engines.
SUBSTANCE: invention relates to methods and systems for vehicle engine control. Result is achieved in that the method of engine cold-start control may include initiating fuel injection for cylinder combustion with manifold pressure lowered via intake throttle adjustments. Manifold pressure is lowered based on an optimization between cylinder charge reduction and improved fuel boiling at the lower pressure.
EFFECT: technical result is an improved engine's ability to start with gasoline fuel, alcohol-based fuel or combinations thereof at cold ambient temperatures.
