Method of operating a drive device and corresponding drive device


A method for operating a drive device with an internal combustion engine and an exhaust gas tract having a storage catalytic converter for purifying exhaust gas, a first lambda probe disposed upstream of the storage catalytic converter and a second lambda probe disposed downstream of the storage catalytic converter, includes determining a lambda value for controlling a mixture composition for the internal combustion engine based on a measurement signal from the first lambda probe and an offset value. The offset value is determined with a trim control when a measurement signal of the second lambda probe is in a normal operating range of values, and is adjusted in a regeneration period, during which the storage catalytic converter regenerated, with a predetermined correction value when the measurement signal of the second lambda probe is outside the normal operating range of values.

Control internal combustion engine


It is intended to suppress formation of any excessive rich air-fuel ratio of the air-fuel mixture caused by adhered fuel on an inner wall surface of an intake passage of an internal combustion engine. A throttle valve driving unit is controlled so that if a variation amount of decrease in output of the internal combustion engine exceeds a predetermined variation amount when the output of the internal combustion engine is smaller than a predetermined output in a non-warm-up state in which the temperature of the internal combustion engine is equal to or lower than a predetermined temperature, then an opening degree of the throttle valve becomes a predetermined increased opening degree which is increased as compared with a standard opening degree as an opening degree of the throttle valve to be provided if the variation amount does not exceed the predetermined variation amount.

Internal combustion engine control apparatus


There is provided an internal combustion engine control apparatus that is capable of determining accurately from an ignition discharging time period whether the intake valve and the exhaust valve are in the operative condition or in the inoperative condition. A cylinder deactivation controller causes a first ignition controller to perform a first ignition control on the basis of the ignition timing when issuing no cylinder deactivation request, and causes a second ignition controller to perform a second ignition control on the basis of an energizing time period when issuing the cylinder deactivation controller.

Control device for internal combustion engine


In the control device, a required-operation position of the exhaust-bypass valve, which is set in accordance with an operating condition of the internal combustion engine, is set to a target position, and an exhaust-bypass-valve-driving device is controlled in such a way that a real position, which is detected by a position sensor, agrees with the target position, and when a real position, which is detected by a position sensor, reaches a predetermined abnormality-judgment value, it is judged that an abnormality is caused in a mechanical-connecting condition from the exhaust-bypass valve to the exhaust-bypass-valve-driving device.. .

Variable valve mechanism of internal combustion engine


The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that includes a roller arm including a roller that rotatably abuts against a cam and a side arm provided at a side of the roller arm and that drives a valve, and a switching device that includes a switching pin and a hydraulic chamber provided inside the rocker arm and that switches a drive state of the valve by displacing the switching pin between a coupling position at which the switching pin extends between the roller arm and the side arm and a non-coupling position at which the switching pin does not extend between the roller arm and the side arm based on variations in hydraulic pressure in the hydraulic chamber. The switching pin is provided on an axis of the roller, and the hydraulic chamber is provided inside the roller arm..

Variable valve mechanism of internal combustion engine


The present invention provides a variable valve mechanism, which includes a rocker arm including an input member and an output member; a switching device that switches a drive state of the valve by displacing the switching pin between a coupling position at which the switching pin extends between the first pinhole in the input member and the second pin hole in the output member and a non-coupling position at which the switching pin does not extend; and a lost motion spring. A displacement clearance is formed between an inner peripheral surface of the first or second pin hole and an outer peripheral surface of the switching pin to permit the relative displacement in a range of the displacement clearance at a coupled time so that a tappet clearance is not formed with the input member urged toward the cam by the lost motion spring..

Variable valve timing control device for internal combustion engine


When a lock demand of a camshaft phase occurs, a control mode of a hydraulic control valve s switched to a locking mode after an actual camshaft phase is controlled to a lock phase, and a lock pin (an inner pin and an outer pin) is moved to a lock position. Thus, the camshaft phase is locked at the lock phase, and a timing advance chamber and a timing retard chamber are made a state of communicating with each other through a back space.
