Methods and system for engine cold starting

Systems and methods for cold starting an internal combustion engine are described. In one example, fuel is delivered in four equal amounts into a cylinder during a cycle of the cylinder. The fuel is injected so as to reduce cylinder wall wetting, raise combustion stability, and increase exhaust syst...
