摘要： A method is described for limiting a change in torque transmitted through a vehicle powertrain when in a predetermined range. Such a method minimizes transmission gear separation, or “clunk”. In one approach, the rate cf change of powertrain output is limited when powertrain output is near zero transmitted torque. The limitation is not used under other circumstances so as not to hinder driver performance.

摘要： An internal combustion engine (10) has a plurality of cylinders which are arranged in two cylinder banks. A sensor (131, 132) is assigned to each of the two cylinder banks for determining the composition of the exhaust gas. A control apparatus is provided with which a control factor (fr1, fr2) can be determined for each of the two cylinder banks in dependence upon the output signals generated by the two sensors (131, 132). The fuel mass (ti1, ti2), which is to be injected into the two cylinder banks, can be influenced by the control factors. The two control factors (fr1, fr2) of the two cylinder banks can be compared to each other via the control apparatus. The control apparatus can distinguish between a cylinder-bank independent fault and a cylinder-bank dependent fault in dependence upon the two control factors (fr1, fr2).

摘要： A control system for an automotive vehicle is capable of realizing superior control precision and response ability by an intake air flow rate control on the basis of a fuel injection amount which is, in turn, derived on the basis of a target torque even in lean-burn condition. The control system controls at least one of vehicle speed, a vehicular distance, driving wheel speed, slip ratio toward a target value, derives a target torque of an engine on the basis of the target value, a fuel injection amount for the engine on the basis of the target torque of the engine, a target air supply amount to the engine on the basis of the fuel injection amount derived by the vehicle condition control means and an actual air supply amount of the engine. The control system controls the actual air supply amount toward the target air supply amount.

摘要： A method and an arrangement for operating internal combustion engines is suggested which is operated in at least one operating state with a lean air/fuel mixture. The fuel mass, which is to be injected, or the injection time, which is to be outputted, is determined in dependence upon a desired value. For monitoring the operability, the actual torque of the engine is determined on the basis of the fuel mass, which is to be injected, or the injection time, which is to be outputted, or the outputted injection time and compared to a maximum permissible torque and a fault reaction is initiated when the actual torque exceeds the maximum permissible torque. Parallel to the above, a quantity, which represents the oxygen concentration in the exhaust gas, is compared to at least one pregiven limit value and a fault reaction is initiated when this quantity exceeds the limit value.

摘要： A diagnosis system for a wide-range A/F sensor receives an air-fuel ratio (A/F) of air-fuel mixture supplied to an engine for the A/F sensor. An control unit of the diagnosis system corrects an A/F controlled object of a feedback control on the basis of a detection result of the A/F sensor to adjust the A/F at a target A/F. The control unit diagnoses an abnormality of the A/F sensor from variation of the detection value of the A/F sensor during a time period from the start of the switching of the target A/F. The control unit sets a control gain of an A/F feedback control at a value greater than a normal control gain during the diagnosis.

摘要： A fuel regulator for two-cycle and/or four-cycle internal combustion engines, particularly those found in model airplanes, comprises a microprocessor, a thermocouple exhaust gas temperature sensor, and a fuel regulating valve installed in a low-pressure fuel delivery system between the fuel tank and the carburetor. During operation, the microprocessor continually receives signals from the exhaust gas temperature sensor. These signals are compared with stored temperature ranges to determine the optimum fuel mixture for the current engine operating conditions. If the current engine operating conditions require a variation in the fuel mixture setting, the microprocessor adjusts the degree of opening of the in-line fuel regulating value, and accordingly regulates the flow of fuel into the carburetor.
