Systems and methods for providing simultaneous coolant stagnation and cooled exhaust gas recirculation
21 Sep 21
Systems and methods for simultaneously performing engine coolant stagnation and exhaust gas recirculation (EGR) cooler cooling in an engine include providing a coolant circuit configured to flow coolant through both a block of the engine and an EGR cooler of a cooled EGR (CEGR) system of the engine, a main pump on the coolant circuit that is driven by an electric motor or a crankshaft of the engine to pump coolant through a block of the engine, and a secondary pump on the coolant circuit that, when energized, is configured to pump coolant through the coolant circuit, and, during a cold start of the engine, de-energizing the electric motor or disconnecting the main pump from the engine crankshaft to stagnate coolant in the engine block and energizing the secondary pump to flow coolant through the EGR cooler of the CEGR system.

An ignition control system and method for an engine having a two-step variable valve lift (VVL) system utilizes an ignition control system comprising a plurality of spark plugs each configured to generate one or more ignition strikes during a combustion event in a respective cylinder of the engine and a controller configured to detect a low-to-high or high-to-low lift mode transition of the VVL system and, in response to detecting the low-to-high or high-to-low lift mode transition of the VVL system, command the ignition control system to perform multi-strike ignition for at least one combustion event, wherein commanding the multi-strike ignition mitigates or eliminates at least one of engine torque variations and increased engine emissions resulting from poor combustion quality caused by residual exhaust components within the cylinder from a previous combustion event prior to the low-to-high or high-to-low lift mode transition of the VVL system.
