摘要： A method for heating up a catalytic converter in internal combustion engines having gasoline direct injection is presented and has the steps: shifting the ignition toward retard; checking whether the charge of the cylinders with air exceeds a pregiven threshold; and, dividing the fuel injection into two component quantities which are injected in advance of the ignition when the air charge exceeds the threshold.

摘要： The aim of the invention is to reduce exhaust emission during the staring phase of a direct-injection internal combustion engine. For this purpose, at least one first injection per working cycle takes place when the internal combustion engine is cold, especially during the starting and/or warm-up phase, thereby producing a substantially homogeneous, combustible fuel/air mixture (56) in the combustion chamber (12). In the same working cycle at least one further injection is supposed to take place which produces a substantially rich fuel/air mixture (64) in the zone of the ignition device (34). The lambda value of the fuel/air mixture (64) produced by the second injection in the zone of the ignition device (34) is smaller than the lambda value of the fuel/air mixture (56) present in the remaining combustion chamber.

摘要： A vibration exciter is provided. The vibration exciter includes a shaft and at least two unbalanced weights arranged on the shaft, in which the radial distance of the common center of gravity of the unbalanced weights from the rotational axis of the shaft is adjustable in an infinitely variable way by means of a gear. The vibration exciter comprises a gear which is a spatial coupling gear, e.g. a spatial vibration slider gear. A simple and compact configuration of the vibration exciter is thus proposed, in which the required adjusting forces for changing the imbalance are very low.

摘要： A method for operating an internal combustion engine and a device for implementing the method may allow a catalytic converter diagnosis with a high degree of accuracy. At least one catalytic converter is positioned in the exhaust-gas region of the internal combustion engine, and a lambda sensor, which is configured as broadband lambda sensor, is positioned downstream from the catalytic converter or downstream from a section of the catalytic converter. The catalytic converter diagnosis is based on the evaluation of a measure for the oxygen storage capacity of the catalytic converter/within the catalytic converter. An at least approximately empty/filled oxygen reservoir of the catalytic converter is assumed. A change in the lambda setpoint value of the internal combustion engine to an excess air factor lambda that is greater than 1/less than 1 follows. Subsequently, a first change of the lambda signal is detected initially. Determined is a measure for the oxygen stored/discharged following the first change of the lambda signal. The determination of the stored/discharged oxygen is terminated if either a second change in the lambda signal is detected or if the measure of oxygen exceeds a threshold value.
