摘要： Techniques for controlling a forced-induction engine having a low pressure cooled exhaust gas recirculation (LPCEGR) system comprise determining a target boost device inlet pressure for each of one or more systems that could require a boost device inlet pressure change as part of their operation and boost device inlet pressure hardware limits for a set of components in the induction system, determining a final target boost device inlet pressure based on the determined sets of target boost device inlet pressures and boost device inlet pressure hardware limits, and controlling a differential pressure (dP) valve based on the final target boost device inlet pressure to balance (i) competing boost device inlet pressure targets of the one or more systems and (ii) the set of boost device inlet pressure hardware limits in order to optimize engine performance and prevent component damage.

摘要： Systems and methods for a turbocharged gasoline engine utilize a controller configured to receive a set of parameters including a measured pressure delta across an exhaust gas recirculation (EGR) valve disposed in a low pressure EGR (LPEGR) system of the engine and a measured pressure at an outlet of a differential pressure (dP) valve disposed in and distinct from a throttle valve of an induction system of the engine. The controller is further configured to determine a set of modeled pressures based on the set of parameters, a target EGR valve mass flow, a target EGR valve delta pressure, a current dP valve mass flow, and a pressure at an outlet of the air filter, determine target positions for the EGR valve and the dP valve based on the set of modeled pressures, and control the EGR valve and the dP valve based on their respective target positions.

摘要： A system and method for controlling condensation formation in an engine having EGR and forced induction includes a controller for determining a water vapor mass fraction of an exhaust stream based on a water vapor mass fraction of an intake stream and water vapor from combustion. An estimated condensation temperature (CT) is determined for a current EGR level based on the water vapor mass fractions and is compared to an intake stream temperature upstream of the compressor inlet. The controller commands the current EGR level as a maximum EGR level upon determining the intake stream temperature is less than the CT, and an increase in the current EGR level upon determining the intake stream temperature is greater than the CT. An air charge temperature (ACT) of the forced induction system may be controlled based on utilizing a target ACT as the CT to be controlled by a coolant pump.

摘要： A boost purge ejector tee arrangement is integrated into a turbocompressor associated with an engine and includes first and second passages, an inlet port and a nozzle. The first passage is formed into a housing of the turbocompressor and includes an outlet in communication with a turbocompressor inlet. The second passage is formed into the housing and includes a boost air inlet in communication with an internal outlet area of the turbocompressor and intersecting the first passage. The inlet port is associated with the housing and intersects the first passage. The nozzle is positioned in the first passage such that an outlet of the nozzle is proximate the intersection of the inlet port and first passage. During a boost mode of operation, the second passage is adapted to receive boost air flow, which flows through the nozzle thereby creating a vacuum and drawing purge through the inlet port.

摘要： A system for a vehicle includes a mode control module and a valve control module. The mode control module selectively sets an ignition mode for an engine to one of a spark ignition (SI) mode and a homogenous charge compression ignition (HCCI) mode. In response to the ignition mode transitioning from the SI mode to the HCCI mode during a first engine cycle, the valve control module operates an exhaust valve in a high lift mode during a second engine cycle, operates an intake valve in a low lift mode during the second engine cycle, and operates the exhaust and intake valves in the low lift mode during a third engine cycle. The first engine cycle is before the second engine cycle, and the second engine cycle is before the third engine cycle.

摘要： A stop/start system and method for an engine of a vehicle include a valve control system configured for full lift control of respective intake and exhaust valves of a plurality of cylinders of the engine and a controller of the engine configured to perform an engine stop event including initiating a fuel shutoff (FSO) event whereby fueling to the engine is disabled and the engine fully stops after a stop period and, in response to initiating the FSO event, commanding the valve control system to close each intake valve prior to closing its respective exhaust valve to (i) expel any residual gases from the cylinders during respective exhaust strokes prior to closing the respective exhaust valves, and (ii) prevent air-only intake and compression within the cylinders during the stop period to thereby mitigate or eliminate noise/vibration/harshness (NVH) caused by the air-only intake and compression.

摘要： An engine control system for a vehicle includes an oxygen mass flow rate module, an oxygen per cylinder module, and a fuel control module. The oxygen mass flow rate module generates a mass flow rate of oxygen flowing into an engine based on a mass air flow rate (MAF) into the engine and a percentage of oxygen by volume measured using an intake oxygen (IO) sensor in an intake system. The oxygen per cylinder module generates a mass of oxygen for a combustion event of a cylinder of the engine based on the mass flow rate of oxygen flowing into the engine. The fuel control module controls fueling to the cylinder for the combustion event based on the mass of oxygen.

摘要： A control technique for an engine having a two-step variable valve lift system includes a controller receiving a pressure in an intake manifold of the engine from a manifold absolute pressure (MAP) sensor and a position of an EGR valve of the engine from an exhaust gas recirculation (EGR) sensor. In response to the controller detecting an upcoming HL-to-LL valve state transition, a set of airflow actuators of the engine is controlled, based on the intake manifold pressure and the EGR valve position, to generate a first torque reserve. In response to generating the first torque reserve, the controller then commands the HL-to-LL transition and depletion of the first torque reserve during the HL-to-LL transition to mitigate torque disturbance associated with this transition.
