    摘要: In a fuel injection system for an internal combustion engine, the system calculates the pulse width of the angle-synchronous fuel injection pulses from a main load sensor, such as an inlet manifold pressure sensor (22) or a hot film or hot wire air mass meter (24). Under rapidly-changing load conditions of the engine, the signal from the main load sensor is not sufficiently accurate to maintain a closely stoichiometric mixture. The present invention provides a throttle valve angle sensor for monitoring the degree of opening of an engine throttle (18), and changes the calculation of the basic angle-synchronous fuel injection signal when the measured rate of change of the throttle valve angle reaches a predetermined valve. The change of calculation may comprise altering filtering characteristics of a filter function normally applied to the basic angle-synchronous fuel injection signal, altering the sampling of the signal from the engine load sensor, or deriving the basic angle-synchronous fuel injection signal from the throttle valve angle signal instead of from the main load sensor signal. Furthermore, the load change compensation may be changed to a calculation from the throttle valve load signal instead of the main load signal. The system may also be arranged to inject one or more intermediate asynchronous fuel injection pulses in between the normal angle-synchronous injections, to enable the fuel/air mixture to follow a rapid change in engine load more closely.

    摘要: Methods, systems, and computer-readable storage media determining a behavior model of a computing system under test. In some implementations, actions include executing, using a user interface of a computing SUT, an initial test script on the SUT; recording, after executing the initial test script, a state of the SUT in the behavior model by observing one or more events that can be triggered using the user interface of the SUT; and iteratively refining the behavior model until an end condition is reached by generating one or more new test scripts, executing the new test scripts on the SUT to test unobserved behavior, and recording one or more new states reached by executing the new test scripts on the SUT in the behavior model.

    摘要: A method and a device for operating an internal combustion engine make it possible to shift the combustion limit. In this context, a predefined output variable of the internal combustion engine such as the torque, for example, is realized in at least one operating state of the internal combustion engine by at least a retardation of an ignition angle. It is checked whether, due to the retardation of the ignition angle, a variable like, for example, a misfiring, characteristic for the combustibility of the air/fuel mixture in a combustion chamber of the internal combustion engine, exceeds a predefined limiting value in terms of a deterioration of the combustibility, and in this case, at least one actuator of the internal combustion engine, different from an actuator for setting the ignition angle, such as the exhaust-gas recirculation valve or EGR valve, for instance, is controlled along the lines of improving the combustibility of the air/fuel mixture.

    摘要: An internal combustion engine, in particular for a motor vehicle, in which fuel may be injected into a combustion chamber during an intake phase in a first mode of operation or during a compression phase in a second mode of operation, and in which exhaust gases may be sent to a catalytic converter. A control unit determines a temperature difference between an actual exhaust gas temperature and a setpoint exhaust gas temperature at an operating point having a low exhaust gas temperature. In addition, at least one additional injection after combustion is implemented by the control unit as a function of the temperature difference.
