摘要： A control system includes a starter control module, a mode setting module, a throttle control module, and a fuel control module. The starter control module initiates cranking of a spark ignition direct injection (SIDI) engine in response to user actuation of an ignition switch. The mode setting module sets a mode of operation to a coldstart mode when an engine coolant temperature is less than a predetermined temperature during the cranking. The throttle control module allows a throttle valve to be biased to a predetermined open position when the SIDI engine is off and, in response to the setting of the mode to the coldstart mode, selectively closes the throttle valve relative to the predetermined open position during the cranking. The fuel control module, in response to the setting of the mode to the coldstart mode, disables direct injection of fuel for a first combustion event during the cranking.

摘要： A thermal management system includes a catalytic converter module that determines whether a catalytic converter is active. A selective catalytic reduction (SCR) catalyst module determines whether a SCR catalyst is active. An engine control module adjusts an air and fuel ratio of an engine to operate at a stoichiometric ratio and retards spark of the engine when the catalytic converter is not active. The engine control module at least one of performs post fuel injection and directly injects fuel into an exhaust system of the engine when the catalytic converter is active and the SCR catalyst is not active.

摘要： A desulfation control system includes a desulfation control module and a spark control module. The desulfation control module initiates a desulfation process in an emission reduction device by increasing temperature of the emission reduction device. The spark control module retards a spark timing to increase the temperature of the emission reduction device in response to the desulfation control module initiating the desulfation process.

摘要： An engine mode control system for an internal combustion engine includes a transition control module and an intake cam phaser control module. The transition control module controls a transition from a first engine mode to a second engine mode and determines a desired air mass. The engine is operated at a first air/fuel ratio (AFR) in the first engine mode and at a second AFR in the second engine mode. The desired air mass is based on the second AFR. The intake cam phaser control module adjusts the intake cam phaser based on the desired air mass during the transition.
