Abstract: This invention provides an improved variable cam phaser for an automobile engine equipped with a controller capable of enabling execution of a given phase angle varying command in a shortened response time. The variable cam phaser has two control rotors which are arranged coaxial with a camshaft and rotatable relative to each other under the influence of two electromagnetic actuators and driven by the crankshaft of the engine. The variable cam phaser also has a relative phase angle varying mechanism for varying the relative phase angle of the camshaft relative to the crankshaft. When the two electromagnetic actuators are simultaneously energized, the two control rotors are held mutually unrotatable. However, when the braking torque of one actuator is reduced, the control rotor associated with that actuator is rotated relative to the other control rotor to immediately start the execution of the command.

Abstract: An internal combustion engine includes a cylinder block defining a cylinder, a cylinder head, an intake valve, an exhaust valve, and a variable exhaust valve timing mechanism. The engine also includes a turbocharging system configured to pressurize ambient airflow for delivery to the cylinder. The turbocharging system includes a low-flow turbocharger, a high-flow turbocharger, and a flow control device for selectively directing post-combustion gas to the low-flow and high-flow turbochargers. A controller directs the post-combustion gas to the low-flow turbocharger and selects a first predetermined exhaust valve timing when the engine operates below a predetermined speed and above a predetermined load. Alternatively, the controller directs the post-combustion gas to the high-flow turbocharger and selects a second predetermined exhaust valve timing at or above the predetermined engine speed. The first predetermined exhaust valve timing traps less post-combustion gas in the cylinder as compared to the second predetermined exhaust valve timing.

Abstract: A control device is configured that can shorten the time required for a system to stop due to an ignition switch operation in a situation in which the internal combustion engine is stopped due to stop control. The control device includes a control unit that, in the situation in which the internal combustion engine is stopped due to stop control, if the transmission mechanism is operated to a second shift position that is different from a first shift position in which the vehicle can travel, executes phase conversion control to shift a valve opening/closing timing control mechanism from a first lock phase to a second lock phase.

Abstract: A system according to the principles of the present disclosure includes a first burn duration module and a spark control module. The first burn duration module determines a first duration of at least a portion of a fuel burn within a cylinder of an engine from a first time when a first predetermined percentage of a mass of fuel within the cylinder is burned to a second time when a second predetermined percentage of the fuel mass is burned. The spark control module controls a spark plug to adjust spark timing of the cylinder based on the first burn duration.

Abstract: [Problems to be Solved]In the valve opening and closing timing controlled by an ECU, since the responsivity of a phase varying apparatus becomes low and the valve opening and closing timing cannot be appropriately controlled in the state of low engine rpm, desired engine characteristics cannot be obtained. Therefore, it is a problem to be solved by the present invention to provide a method and an apparatus for controlling a phase varying apparatus capable of obtaining the considerably high responsiveness of the phase varying apparatus under condition of low engine rpm.[Solution]The above problem can be solved by a phase control method for controlling a phase varying apparatus constituted so as to calculate an estimated relative angle value one step later by the Kalman filter using a relative angle calculated from rotational velocity values of the associated shafts in the current step and a command value to an electromagnetic clutch in the current step, input the estimated relative angle value to a sliding mode controller as a feedback signal, calculate a command value to the electromagnetic clutch one step later based on the value of the feedback signal and output the command signal.
