Abstract: An engine valve timing control device is disclosed, in which the valve overlap amount is controlled according to the fuel property, thereby keeping the drivability unchanged even when the fuel is changed. A shortage of engine output and cold hesitation are prevented at the same time when the engine temperature is low. The device is for controlling the valve operation characteristic of an internal combustion engine, and comprises a variable valve mechanism capable of changing the valve overlap amount and a control unit for controlling the operating amount of the variable valve mechanism in accordance with the engine operating conditions. The property of the fuel burnt in the engine is determined as light, intermediate or heavy. Under the engine operating condition where the overlap amount otherwise is the same, the operating characteristic of the intake valve and the exhaust valve is controlled in such a manner that the overlap amount of the intake valve or the exhaust valve is smaller for the intermediate fuel than for the light fuel and smaller for the heavy fuel than for the intermediate fuel. Also, the control of the valve overlap amount can be corrected in accordance with the engine temperature.

Abstract: A system and method for measuring and controlling cam timing of an internal combustion engine uses a filtering method based on a number of equally spaced teeth mounted on the camshaft. The filtering method specifically removes certain oscillations caused by camshaft torsional effects. The filtering method also specifically removes oscillations due to production variations. These oscillations are removed with minimal effect on closed loop system response.

Abstract: A system and method for determining abnormality of a VVT (variable valve-timing control mechanism) and controlling the VVT on consideration of responsiveness thereof. When execution conditions for abnormality determination of the VVT are present, speed of change in angle of rotation ACSPD is calculated on a basis of transition in actual angle of rotation of the VVT as a responsiveness-detection parameter. In the abnormality determination, if the speed of change in angle of rotation ACSPD is less than a programmed determination value, it is determined that followup of VVT operation is faulty, and an abnormality-determination flag XVTFAIL is set to "1" to indicate that some abnormality has occurred. Also, a warning light is placed in an illuminated state. Target relative angle of rotation of the VVT is appropriately established, and VVT operation is suppressed on the basis of this abnormality determination. As a result, drivability and emissions performance degradation can be suppressed.

Abstract: In an internal combustion engine control system for controlling an internal combustion engine, comprising a fuel injection control apparatus for controlling fuel injection quantity to be injected by a fuel supply system for supplying fuel to the internal combustion engine, and fuel injection timing, and a variable valve control for continuously or gradually varying at least opening timing, closing timing or lift of a intake valve or an exhaust valve for sealing up a combustion chamber of the internal combustion engine. The fuel injection control apparatus controls at least fuel injection quantity or fuel injection timing on the basis of a value of a controlled variable provided by the variable valve control. Since air quantity can be regulated by a variable valve timing mechanism, pumping loss and fuel consumption can be reduced. Fuel injected into the combustion chamber can be atomized by opening the intake valve so that a shock wave is generated in the combustion chamber and, consequently, stable combustion can be achieved without deteriorating the quality of the exhaust gas.

Abstract: An internal combustion engine, which outside of the upper load range is operated with a lean mixture, has a device which sets the fuel-air mixture in the combustion chamber into increased motion. This device is activated as soon as a switchover is made to lean-burn operation, and is deactivated when the change is made from lean-burn operation to stoichiometric operation. To ensure that these switchover operations of the device will influence the engine torque as little as possible, the fuel flow is reduced for a specifiable period of time after the device is switched on, and the fuel flow is increased for a specifiable period of time after the device is switched off.

Abstract: An electromagnetic valve has a first and a second electromagnetic coil and an armature. The first electromagnetic coil generates a magnetic filed to cause the armature to move a valve for closing. The second electromagnetic coil generates a magnetic filed to cause the armature to move the valve for opening. The first electromagnetic coil is energized to generate the magnetic field. Measurement of time at a first moment is started before the valve is moved to a first position at which the first electromagnetic coil is temporarily de-energized and to output a first signal after a predetermined period of time has passed from the first moment. The temporarily de-energized first electromagnetic coil is energized in response to the first signal. The first electromagnetic coil is de-energized when the valve is fully closed. The second electromagnetic coil is energized to generate the magnetic field after the first electromagnetic coil is de-energized. Measurement of time at a second moment is started before the valve is moved to a second position at which the second electromagnetic coil is temporarily de-energized and to output a second signal after a predetermined period of time has passed from the second moment. The temporarily de-energized second electromagnetic coil energized in response to the second signal. The second electromagnetic coil is de-energized when the valve is fully opened. The first electromagnetic coil is energized after the second magnetic coil is de-energized.

Abstract: A method of controlling velocity of an armature of an electromagnetic actuator as the armature moves from a first position towards a second position is provided. The electromagnetic actuator includes a coil and a core at the second position. The coil generates a magnetic force to cause the armature to move towards and land at the core. Spring structure acts on the armature to bias the armature away from the second position to a resetting position. The method includes selectively energizing the coil to permit the armature to move at a certain velocity towards the core. A certain voltage corresponding to a voltage across the coil is determined when the armature is approaching the core. The certain voltage corresponds to a rate of change of magnetic flux and is used as a feedback variable to control energy to the coil so as to control a velocity of the armature as the armature moves towards the core. In one embodiment, the certain voltage is a measured terminal voltage of the coil. In another embodiment, the certain voltage is a parametrically determined voltage which mirrors the terminal voltage.

Abstract: An internal combustion engine having a variable valve timing mechanism, a throttle valve and a flow control valve for controlling the generation of turbulence in a combustion chamber. The control valve is operated so as to generate turbulence in the combustion chamber under low- and mid-range performance. When this turbulence is generated, the timing of opening of the intake valve is retarded. Also, the throttle valve is opened more fully when the control valve is closed so as to control the engine speed and maintain the desired engine speed.

Abstract: A method of reducing feed gas emissions and improving fuel economy in an internal combustion engine uses a variable cam timing mechanism and an electronically controlled throttle. The method includes: a) predetermining ranges of negligible torque demand, small torque demand, moderate torque demand, high torque demand and maximum torque demand; b) determining actual torque demand; c) using conventional cam phasing and pedal-to-throttle relationship if actual torque demand corresponds with the negligible torque demand range; d) using cam phasing of magnitude in transition between conventional and fully retarded cam phasing and retaining conventional pedal-to-throttle relationship if actual torque demand corresponds with the small torque demand range; e) using fully retarded cam phasing and electronically adjusting throttle position to meet actual torque demand if actual torque demand corresponds with the moderate torque demand range; f) using cam phasing of magnitude in transition between fully retarded and conventional cam phasing and holding throttle position constant if actual torque corresponds with the high torque demand range; and g) using conventional cam phasing and pedal-to-throttle relationship if actual torque corresponds with the maximum torque demand range. Similar schemes are provided for intake advance and exhaust retard strategies.
