Abstract: A system according to the present disclosure includes a fuel control module and at least one of a desired air per cylinder (APC) module and a predicted manifold absolute pressure (MAP) module. The desired APC module determines a desired amount of airflow to each cylinder of an engine. The predicted MAP module predicts a pressure within an intake manifold of the engine at a future time. The fuel control module selectively adjusts a fuel injection parameter of the engine based on at least one of: a change in the desired air per cylinder from a first time to a second time; and a change in the predicted manifold pressure from the first time to the second time.

Abstract: Systems and methods are provided for determining and correcting air/fuel imbalance between cylinders of an internal combustion engine. A deactivation strategy is determined and implemented. An evaluation is made of whether the engine is operating with an air/fuel imbalance between cylinders. When an imbalance is identified, an alternate deactivation strategy is implemented. Based on outcomes of the alternate deactivation strategy, a source cylinder of the air/fuel imbalance is identified, and fuel flow to the source cylinder is corrected.

Abstract: A fuel control system according to the principles of the present disclosure includes a parameter determination module, a parameter learning module, and an injector driver module. The parameter determination module determines a parameter of a fuel injector in an engine at an operating condition of the engine. The parameter learning module identifies index values in a table based on the engine operating condition and adjusts learned values of the fuel injector parameter corresponding to the index values based on the determined value of the fuel injector parameter. The injector driver module selectively applies power to the fuel injector based on the learned values.

Abstract: A method for controlling re-circulation of exhaust gas (EGR) in an internal combustion engine includes receiving a signal indicative of an engine operating temperature and comparing the engine operating temperature to a first predetermined IEGR threshold. When the engine operating temperature is less than the first predetermined internal EGR threshold, a first internal EGR mode is activated, whereby engine emissions may be reduced or combustion stability may be enhanced. When the engine operating temperature is greater than the first predetermined internal EGR threshold, the first internal EGR mode is deactivated, and a second internal EGR mode is activated, whereby emissions may be reduced as exhaust system heating is accelerated. When the operating temperature is greater than the second temperature threshold, the second internal EGR mode may be deactivated a third mode may be enabled with only external EGR.

Abstract: A vehicle system includes an engine defining a plurality of cylinders and configured to combust a fuel. A method of increasing efficiency of an engine includes controlling an amount of fuel being injected into the plurality of cylinders of the engine via a respective fuel injector. An exhaust gas recirculation (EGR) system is in selective fluid communication with a second subset of the plurality of cylinders and the air intake system to route the second exhaust product from the second subset of the plurality of cylinders to an air intake system. A valve is coupled to the EGR system and the exhaust system. A first sensor is disposed between the valve and the air intake system, and measures an amount of reformate in the second exhaust product when the valve is in a second position.
