Abstract
A method to supply fuel to an engine of a vehicle is provided. The method includes adjusting a direct injection of fuel into a cylinder of the engine based on whether the vehicle is in a pre-delivery state. In one example, the method includes reducing an amount of fuel in a post injection to reduce cylinder bore wetting effects and lubricant dilution during the engine cold start. After pre-delivery, a normal post injection schedule may be used to reduce emissions.
