摘要： A system for operating a heating element (114) of a ceramic sensor (112) which is arranged in the exhaust channel (104) of an internal combustion engine (100) and which can be heated by the heating element (114). If the internal combustion engine (100) is in an operating state in which it can be assumed that liquid is present in the exhaust channel (114) of the internal combustion engine (100), the heating element (114) is not activated or is triggered such that the ceramic sensor (112) is operated below a critical temperature (TSeK). Above the critical temperature (TSeK) there is a risk that the ceramic sensor (112) will be damaged due to contact with liquid.

摘要： In a method and apparatus for monitoring the operating capability of a catalyzer in the exhaust duct of an internal combustion engine, the operating capability of the catalyzer is assessed on the basis of the increase in temperature produced by the exothermic conversion of the exhaust gases in the catalyzer. The increase in temperature is determined with the aid of two temperature signals, the first temperature signal being produced on the basis of a measurement downstream of the catalyzer and the second temperature signal being formed with the aid of a temperature model. The temperature model may form the temperature downstream of a completely inoperational catalyzer, a catalyzer which is still just sufficiently operational, or a catalyzer which is fully operational. The assessment of the operating capability of the catalyzer is performed on the basis of criteria which are matched to the temperature model used.

摘要： A method and a device for forming a simulated signal of the temperature of the exhaust gas, exhaust gas sensor or catalytic converter for an internal combustion engine. Using a temperature characteristic depending on the air mass stream, and two low-pass filters with time constants depending on the air mass stream, the exhaust gas temperature upstream from the catalytic converter, the exhaust gas sensor temperature and the catalytic converter temperature are simulated. The air mass, integrated since the time the internal combustion engine is started, is compared with two threshold values to determine whether or not there is still condensation water present in the exhaust gas channel upstream from the catalytic converter and/or in the catalytic converter itself. If condensation water is present, the simulated temperature(s) is limited to a value of approximately 50.degree. to 60.degree. C. If the entire condensation water in the exhaust gas channel and/or in the catalytic converter was not evaporated during a short run of the internal combustion engine, or if the temperature of the internal combustion engine is extremely low when it is started, then extended times for evaporation of the condensation water are estimated and simulated by increased threshold values for the integrated air mass.

摘要： The invention is directed to a method for determining the storage capacity of a catalytic converter of an internal combustion engine with the aid of a first signal from an oxygen-indicating first probe mounted forward of the catalytic converter and a second signal from an oxygen-indicating second probe mounted rearward of the catalytic converter. The first and second signals show the change from rich to lean and vice versa and the method includes the steps of: determining the storage capacity as a quantity proportional to the time-dependent integral of an integration variable; starting the integration at a time point at which said first signal changes from rich to lean or vice versa; and, ending the integration after a time interval. The method does not need a special test operation of the engine to determine the storage capacity of the catalytic converter. Instead, the method can be carried out in any steady-state operating condition for which the probe rearward of the catalytic converter regularly indicates jumps from rich to lean and vice versa. The invention is also directed to an arrangement for carrying out the invention.

摘要： To increase the resolution of digital words, for example eight-bit words, being supplied via a digital/analog (D/A) converter (2) to a closed control loop, the lowest-order bit (2a) is chopped with a duty cycle, that is, controlled pulse duration/pulse gap ratio, for accurate resolution of the entire word being transmitted. The D/A converter will provide an output of undulating or wavy form, which undulations or waves are averaged or integrated by a low-pass filter (5) or low-pass transmission characteristics of a controller (6) or the overall control loop (4-6-7-8-9-10-11-4) to which the analog signal is applied as a command signal. The system is particularly suitable for accurate control of a fuel supply control element, such as a throttle (9), in the induction pipe of an internal combustion engine using only eight-bit command words, by not transmitting the lowest-order bit in steady-state form but, rather, chopped with controlled duty cycle for conversion of the chopping effect into analog form in the D/A converter (2). The repetition frequency of the pulse duration modulation is suppressed by the low-pass filter or filter characteristics of the control loop.

摘要： To sense proper operation of a servo control loop including a fuel control pedal (1) which operates a command control transducer (2), e.g. a potentiometer coupled thereto, to provide a command signal to a controller (3) which energizes an amplifier (4) operating a positioning motor (5) which, in turn, changes the position of a fuel control element (7, 207), the instantaneous position of which is fed back to the controller by a position control transducer (6), a signal processing and logic circuit (9, 13) is provided which has the actual fuel supply signal applied thereto. The actual fuel supply signal is evaluated with respect to predetermined limits, for example at a "rest" or OFF position of the fuel control element. This condition can be sensed, for example, based on operating data of the engine, e.g. when a brake light switch is operated, the engine operates above a certain speed, or the vehicle operates at a certain speed, or the like. Additionally, a position sensing switch (8) coupled to the control pedal (1) can be monitored by determining if the output signal from the command transducer is within a limited range when the switch is in a position indicating that the pedal is at, or close to, OFF or "rest" position. By evaluating the actual signal from the respective transducers at predetermined positions of the elements to which they are coupled, e.g. the fuel control element (7, 207) being against an idle or rest stop (16, 216) or the fuel control pedal (1) being at "rest" position, limit switches, particularly in the engine compartment, can be eliminated.
