Abstract: Methods and systems for use of model predictive control (MPC) controllers utilizing hybrid, quadratic solvers to solve a linear feasibility problem corresponding to a nonlinear problem for an internal combustion engine plant such as a diesel engine air path. The MPC solves a convex, quadratic cost function having optimization variables and constraints and directs the plant per the output solutions to optimize plant operation while adhering to regulations and constraints. The problem includes a combination of iterative and direct calculations in the primal space depending on whether a partial step (iterative) or a full step (direct) is attempted. Further, primal and dual space array matrices are pre-computed and stored offline and are retrieved via use of a unique identifier associated with a specific active set for a set of constraints. Such hybrid and/or offline calculations allow for a reduction in computational power while still maintaining accuracy of solution results.

Abstract: Methods and systems are provided for regulating airflow through a charge air cooler integrated in an intake assembly. In one example, an engine intake assembly comprises a plenum having an integrated charge air cooler (CAC), a first header seal positioned around a circumference of a first CAC header, and a first rotatably movable seal positioned in a bypass passage of the plenum. The first movable seal interfaces via sliding contact with the first header seal and adjusting a position of the first movable seal may vary the amount of airflow through the bypass passage.

Abstract: An internal combustion engine of the present invention is an internal combustion engine equipped with port injectors. Further, the internal combustion engine has an ISC passage that connects an upstream side and a downstream side of a throttle valve in an intake passage, and an ISC valve that regulates an amount of air flowing in the ISC passage. A control device of the present invention performs valve opening control that makes an opening degree of the ISC valve an opening degree larger than a reference opening degree when request torque required by the internal combustion engine is smaller than estimated torque that can be generated in the internal combustion engine, and sets a timing for fuel injection from the port injector at an opening timing of an intake valve of a cylinder in which the port injector is installed during the valve opening control.

The system further includes a control computer configured to determine at least one of torque demand, pressure across the compressor, and pressure gradient ratio between the exhaust manifold and the intake manifold relative to one of exhaust manifold pressure, intake manifold pressure, and 1. The control computer performs at least one of: closing the EGR valve in response to the determined at least one of torque demand, pressure across the compressor, and pressure gradient ratio, and lessening restriction provided by the variable geometry turbine responsive to the determined at least one of torque demand, pressure across the compressor, and pressure gradient between the exhaust manifold and the intake manifold.

Abstract: An EGR apparatus includes a EGR passage and an EGR valve provided in the EGR passage to regulate an EGR flow rate in the EGR passage. An ECU closes the EGR valve from an open state prior to start of deceleration of the engine based on engine rotation speed detected by a rotation speed sensor, accelerator opening degree detected by an accelerator sensor, and actual opening degree of the EGR valve. During deceleration of the engine, the ECU obtains a target opening degree of the EGR valve according to the separately detected engine rotation speed and accelerator opening degree from a target opening degree map and starts to close the EGR valve when a difference between an actual opening degree and the target opening degree of the EGR valve exceeds a predetermined value.

Abstract: High pressure loop exhaust gas circulation is achieved in an exhaust system (10) of an engine (12) by providing an adjustable valve (100) in an exhaust passage (18) of the engine (12). The valve (100) is configured to control fluid flow through the passage (18) and generate pressure to drive the high pressure exhaust gas recirculation. The valve (100) includes a valve inner surface (110) that has a curvilinear profile when viewed in longitudinal cross section. An actuator (140) is connected to the valve (100), and is configured to move the valve (100) relative to the exhaust passage (18) so as to control exhaust gas pressure within the exhaust passage (18). In some embodiments, a pilot tube (280) is used in combination with the valve (100) to generate high pressure exhaust gas recirculation at the engine (12) intake.
