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： The invention is directed to a method of checking a tank-venting apparatus for a motor vehicle equipped with a fuel tank and an internal combustion engine having an intake pipe. The apparatus includes an adsorption filter having a venting end and an intake end, a supply line connecting the intake end to the tank and a connecting line interconnecting the intake pipe of the engine and the intake end of the adsorption filter. A tank-venting valve is mounted in the connecting line between the intake pipe and the intake end of the adsorption filter and a drive unit for actuating the tank-venting valve. The method includes the steps of: changing the open state of the tank-venting valve when a pregiven operating state range of the engine is present; detecting the difference pressure between the pressure at the intake end of the adsorption filter and the ambient pressure; checking if the difference pressure or the end value of the difference pressure change lies in a predetermined range after the open state of the tank-venting valve is changed; and, issuing a fault announcement if neither the difference pressure, the time constant of the difference pressure change nor the end value of the difference pressure change lies in said predetermined range. The invention utilizes the realization that the difference pressure is based on the gas flow into and out of the adsorption filter. The difference pressure drops when the outflow is clogged or when there is a leak. On the other hand, the difference pressure increases when the inflow is clogged. In this way, the operability of the tank-venting apparatus can be checked in a simple manner.

摘要： A method and a device for controlling and/or regulating the idling speed of an internal combustion engine is suggested, wherein changes of the operating condition of the internal combustion engine are considered by means of a precontrol being dependent from operational characteristics dimensions of the internal combustion engine, as well as being stabilized during long term changes of the operational condition of the internal combustion engine with the assistance of a correction of the precontrol. Thereby, it is differentiated between a direct correction as well as an indirect correction, for example, additive correction of the precontrol. Block diagrams are provided for both correction possibilities. Also, a plurality of criteria are stated with the assistance of which the time range of the correction may be defined. For realizing the method with the assistance of a corresponding programmed electronic computer the precontrol and the correction for the precontrol are designed in form of support locations with intermediately disposed interpolations in one exemplified embodiment.

摘要： The invention is directed to a multi-engine drive system with at least two engines which have a common crankshaft. In order to test if both engines are operating properly, a mutually oppositely directed modulation of the throttle flap angles of the throttle flaps is caused by a control unit to occur periodically in the context of a test function. If this test function causes a change in the rotational speed of the crankshaft, then this means that the two engines are no longer operating symmetrically so that a disturbance is present. In this way, a continuous monitoring of the operation of both engines is provided.

摘要： The invention is directed to a mixture metering arrangement for an internal combustion engine and includes an exhaust-gas sensor which is exposed to the exhaust gas of the internal combustion engine. The exhaust-gas sensor indicates the air ratio lambda and preferably has a two-level characteristic. The sensor output signals are acted upon by a follow-on controller which is preferably a PI-controller. The controller output quantity acts upon the mixture composition in a corrective fashion. In this arrangement, the control oscillation of the controller output quantity is adjusted to a predetermined amplitude by means of a superposed control. In particular, the integral component of the control oscillation is influenced in a manner causing it to have the same amplitude as the proportional component while in the steady operating condition. Thus, it is possible to maintain the maximum control frequency in any operating range of the internal combustion engine so that the controller always operates at its optimum. In addition, the effects of deviations occurring from one engine to another or from one exhaust-gas sensor to another as well as of long-term variations are suppressed.

摘要： In operation of an internal combustion engine, an air filling (rl) in a combustion chamber is ascertained, taking into account a pressure (ps) in an intake conduit. It is proposed that the air filling (rl) be ascertained on the basis of a model (A), which as its input variables receives an rpm (nmot) of a crankshaft and a ratio of the pressure (ps) in the intake conduit (22) to an ambient pressure (pu).

摘要： A method and a device for operating an internal combustion engine having exhaust-gas recirculation are provided, which make it possible to dispense with an ambient-pressure sensor. In this context, an intake-manifold pressure and an ambient pressure are modeled. The intake-manifold pressure is modeled as a function of the modeled ambient pressure. The intake-manifold pressure is also measured. The modeled intake-manifold pressure is compared to the measured intake-manifold pressure. The modeled ambient pressure is adapted as a function of the comparison result. The modeled ambient pressure is adapted only when the exhaust-gas recirculation is inactive.
