    Abstract: A fuel injection system has a common rail storing fuel, a fuel injector injecting the fuel, a fuel-passage supplying the fuel to the fuel injector, and a fuel-pressure sensor detecting a fuel pressure. An ECU acquires a waveform of a fuel pressure representing a change of a fuel pressure based on the detected fuel pressure at the fuel injection. The ECU calculates a speed of a fuel pressure wave forming the waveform of the fuel pressure based on a period of a pulsation of the waveform of the fuel pressure and a fuel passage length, and a fuel density based on the speed of the fuel pressure wave. The ECU further calculates a fuel cetane number, and a kinematic viscosity of the fuel based on the fuel density and the fuel cetane number. The ECU judges fuel properties based on the kinematic viscosity of the fuel.

    Abstract: Disclosed are a control device and a control method that are used with an internal combustion engine in which the air-fuel ratio in the vicinity of an ignition plug differs from the overall air-fuel ratio in a cylinder, and capable of properly fulfilling demands concerning various capabilities of the internal combustion engine by accurately reflecting each of the demands in the operation of each actuator. Three physical quantities, namely, a torque, an efficiency, and an air-fuel ratio, are used as controlled variables for the internal combustion engine. Target values for the controlled variables are then set by integrating at least some of demands concerning a capability of the internal combustion engine into the three physical quantities. Further, in accordance with the target values for the three controlled variables, namely, the torque, the efficiency, and the air-fuel ratio, three operation amounts, namely, an intake air amount adjustment valve opening, an ignition timing, and a fuel injection amount are set, and a fourth operation amount for adjusting the air-fuel ratio distribution in the cylinder is set.

    Abstract: A system of a vehicle includes a fueling prediction module, a short pulse determination module, a torque control module, and a generator control module. The fueling prediction module generates N predicted fueling pulse widths for N future combustion events of an engine, respectively. N is an integer greater than one. The short pulse determination module determines a number of the N predicted fueling pulse widths that are less than a predetermined period. The torque control module selectively increases a torque output of the engine based on the number. The generator control module selectively increases a load imposed by a generator of electricity based on the number.

    Abstract: A fuel injector includes a fuel valve with a valve seat and a movable valve needle, a calibration spring and an electromagnetic actuator with a solenoid and a movable armature. The calibration spring exerts a pressing force on the valve needle for pressing the valve needle in a closing direction towards the valve seat. When the solenoid is electrically energized, the electromagnetic actuator is operable to transfer a lifting force to the valve needle by engagement with the armature for lifting the valve needle from the valve seat to a fully open position against the pressing force of the calibration spring. The calibration spring and the electromagnetic actuator are configured such that the lifting force equals the pressing force in the fully open position.
