摘要：
A cylinder deactivation system comprises a fuel injection module and a cold start control module. The fuel injection module injects a desired amount of fuel into a cylinder of an engine during engine cranking. The cold start control module maintains an intake valve and an exhaust valve associated with the cylinder in respective closed positions while the desired amount of fuel is injected when at least one of an air temperature and a coolant temperature is less than a predetermined cold start temperature.
