Abstract: A method of controlling an engine system includes controlling a fuel injector to perform a zero-fueling injector operation during operation of the engine, the zero-fueling injector operation including a non-zero injector on-time resulting in zero fueling by the injector, determining an injection system pressure change associated with the zero-fueling injector operation, modifying at least one fuel injection control parameter in response to the injection system pressure change, and using the modified fuel injection control parameter to control injection of fuel by the fuel injector during operation of the engine.

Abstract: A fuel injection system includes a fuel supply passage configured to receive a pressurized fuel, a nozzle orifice downstream of the fuel supply passage, and an injection valve positionable to open the nozzle orifice and to close the nozzle orifice. The injection valve has a first configuration with a first lift and a second configuration with a second lift, the first lift being different than the second lift. The fuel injection system includes a fluid-actuated lift control valve configured to cause the injection valve to change from the first configuration to the second configuration.

Abstract: An engine start controller includes an injection amount calculating portion that is configured to calculate, as an assist injection amount, an injection amount of fuel injected from a fuel injection valve of an engine in an engine start-up period until the engine rotation speed exceeds a predetermined starting rotation speed from zero. The injection amount calculating portion is configured such that, in a case in which the rotation speed of the engine is higher than or equal to a threshold value that is a value less than the starting rotation speed, the injection amount calculating portion calculates the assist injection amount to be smaller when the engine is started by using the motor generator than when the engine is started by using the starter.

Abstract: Systems and methods are provided for controlling exhaust gas recirculation (EGR). In one example, an engine system includes a first EGR valve coupling an exhaust manifold to an engine exhaust system, a second EGR valve coupling the exhaust manifold to an engine intake system, and a control unit. The control unit selectively adjusts a position of the first EGR valve based on a target amount, and adjusts a position of the second EGR valve based on the target amount and a position of the first EGR valve. Responsive to a first degradation condition of the first EGR valve, the control unit adjusts the position of the second EGR valve based on the target amount and based on a pressure of the first exhaust manifold, and responsive to a second degradation condition of the first EGR valve, adjusts the position of the second EGR valve based on the target amount.

Abstract: Methods and systems are provided for relieving pressure from a compression locked engine. The engine may be compression locked during an engine start attempt due to operator application of a manual transmission clutch at or around the time of a first combustion event of the engine start. A direct injector of the compression locked cylinder is commanded open to relieve the pressure into the fuel rail.

Abstract: A fuel injection control device for an engine includes an ECU. The ECU is configured to: change a port injection ratio in accordance with an operation state of the engine; execute correction of the total fuel injection amount by reflecting a correction amount in a basic fuel injection amount depending on the operation state when the port injection ratio is changed; and when the ECU changes the port injection ratio and calculates a second correction amount that is the correction amount having one of the positive and negative values during the execution of the correction based on a first correction amount that is the correction amount having the other one of the positive and negative values, limit reflection of the first correction amount in the basic injection amount.

Abstract: A method for reducing the range of fluctuation of the exhaust emission values of identically constructed engine arrangements of a production series, each having an internal combustion engine and an exhaust after treatment system. After manufacturing identically constructed engines, their engine controls are placed into a calibration operating mode and the engines are operated in calibration operating mode. At least one exhaust gas state variable is recorded along the exhaust gas flow and the measurement value is compared with a desired value or desired value range defined for the production series. If necessary, at least one setting variable of the respective engine is adjusted so that the actual value corresponds to the desired value or lies in the desired value range. Then the calibration operating mode stopped, the engine controls are put into a normal operating mode, and the internal combustion engines are operated in the normal operating mode.

Abstract: Methods and systems are provided for temperature control of a high pressure pump (HPP) of a direct injection system. When direct injection is disabled, the HPP and the associated direct injectors are intermittently operated when the HPP temperature rises above a modeled threshold temperature. The HPP and injectors are operated until the HPP temperature falls below the modeled threshold temperature.

Abstract: Provided is an engine control device capable of, when performing control of an in-cylinder oxygen concentration according to engine operation state, controlling an engine to accurately realize vehicle behavior intended by a driver, while suppressing generation of knock noises due to abnormal combustion. The engine control device comprises: a basic target torque-determining part (61) configured to determine a basic target torque based on a driving state of a vehicle including manipulation of an accelerator pedal; a torque reduction amount-determining part (63) configured to determine a torque reduction amount based on a driving state of the vehicle other than the manipulation of the accelerator pedal; a final target torque-determining part (65) configured to determine a final target torque based on the basic target torque and the torque reduction amount; and an engine control part (69) configured, based on a fuel injection parameter preliminarily set correspondingly to an operation state of an engine, to control a fuel injector to enable the engine to output the final target torque, and, when the final target torque changes correspondingly to a change in the torque reduction amount, to correct the fuel injection parameter.

Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.
