Abstract: An intake control apparatus is configured to control a variable valve operating mechanism and an opening degree of a throttle valve. The variable valve operating mechanism varies the valve lift characteristic of the intake valves to control the intake air amount into the cylinders of the engine. The throttle valve produces a negative pressure inside the collector, but in a valve control region including medium loads, the pressure inside the collector is fixed at a weak negative pressure and the intake air amount is controlled by varying the valve lift characteristic of the intake valves. In an internal EGR priority region of low loads, the negative pressure is strengthened somewhat and the lift/duration of the intake valves is increased. When the engine is cold, the negative pressure is adjusted to be close to atmospheric pressure and the lift/duration of the intake valves is reduced.

Abstract: Known method suitable for implementation in a computer program product for VCT closed-loop control system generally includes an integrator to eliminate the steady state error. A novel method suitable for implementation in a computer program product includes a set point filter as well to reduce the closed-loop control overshoot. Low cam torque frequency can reduce the stability of a closed-loop control system when combined with the integral action, and it can also compromise the effect of set point filter. This novel method addresses these two issues by identifying the cam torque direction and pausing control updating when there is no torque available at the desired direction.

Abstract: A rotational angle sensor and a hydraulic pressure control valve are disposed such that a detecting end surface of the rotational angle sensor disposed close to a sensor rotor attached to an exhaust camshaft is located in a spray area of return oil discharged through a drain hole formed at a cam cap, which flows down through a lower drain port of the hydraulic pressure control valve attached on the cam cap from a variable valve timing mechanism. Further, the detecting end surface is located forward in the rotational direction, shown as the arrow a, of the exhaust camshaft so that the return oil can be positively carried toward the detecting end surface by the rotation of the sensor rotor. Accordingly, this can maintain properly detecting accuracy of the rotational sensor disposed close to the camshaft.

Abstract: In a variable intake-valve operating system for an engine enabling a working angle of an intake valve and a phase at a maximum lift point of the intake valve to be varied, a variable working-angle control mechanism is provided to continuously change the working angle of the intake valve and a variable phase control mechanism is provided to continuously change the phase of the intake valve. A control unit is configured to be electronically connected to both the two variable control mechanisms, to simultaneously control these control mechanisms responsively to a desired working angle and a desired phase both based on an engine operating condition. The control unit executes a synchronous control that a time rate of change of the working angle and a time rate of change of the phase are synchronized with each other in a transient state that the engine operating condition changes.

Abstract: An intake valve control system for an internal combustion engine includes a first valve control mechanism for varying an actual operation angle of an intake valve, a second valve control mechanism for varying an actual maximum lift phase of the intake valve and a control unit that operates the first and second valve control mechanisms to adjust an intake air amount by controlling the operation angle predominantly in a low-intake range and controlling the maximum lift phase predominantly in a high-intake range. The control unit is configured to calculate a target operation angle and a target maximum lift phase according to engine operating conditions so that the actual operation angle and maximum lift phase are controlled to the target operation angle and maximum lift phase, respectively, and correct the target operation angle in a transient operating state where the actual maximum lift phase deviates from the target maximum lift phase.

Abstract: The variable valve timing controller controls the valve timing of the intake valve. The variable valve timing controller has a shaft, the stator fixed on the engine and generating the magnetic field around the shaft and rotational phase converter converting the torque applied to the shaft. When the valve timing is in the most delayed timing, the engine can be started. The rotational phase of this timing is called the feasible phase. When the stator stops generating the magnetic field, the load torque arise on the shaft. The rotational phase converter varies the rotational phase into the feasible phase with receiving the load torque from the shaft.

The housing has an outer circumference for accepting a drive force and the rotor connects to a camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating chambers, advance and retard. The vane shifts the relative angular position of the housing and the rotor. The phaser also includes a spool valve comprising a spool slidably mounted within in a bore in the rotor. The spool routes operating fluid from a supply of pressurized fluid to the chambers.
