Abstract
A cold start control module for a direct injection engine includes a fuel flow determination module and a cylinder activation/deactivation module. The fuel flow determination module determines a requested fuel flow. The cylinder activation/deactivation module deactivates at least one of cylinders when the requested fuel flow exceeds a maximum fuel flow of the fuel pump during cold start.
