    摘要: In order for the process and the device to function with as small as possible a number of sensors for operating parameters, a program map (20) is provided from which the intake air pressure (AL) of the charger (3, 5) is derived as a function of the charging pressure (PL), the engine speed (n), and a fuel quantity preset (QK) corresponding to the accelerator position, and there is a device (21) which determines a limit value (QKG1) for the fuel quantity (QK′) metered to the engine (1) as a function of the intake air pressure (AL).

    摘要: The invention is directed to a system for electronically controlling (open loop and/or closed loop) an internal combustion engine of a motor vehicle. By means of at least one measuring unit at least one signal is generated representing the position of a power-determining component and the measuring unit comprises several sensors. The measuring unit is associated with a power-determining component of the vehicle such as a throttle flap or the control rod and/or accelerator pedal. The sensors are checked with respect to their functional capability by comparing the signal values generated by the sensors to each other with respect to a pregiven tolerance range. When a fault of one or more of the sensors is detected, then that sensor or those sensors which is or are unaffected can be determined.

    摘要: In a device for adjusting the injection timing in a diesel engine fitted with EDC, a basic value (SBGWs) of injection timing for operation in the static or steady state is stored in a first characteristic field (20) and a basic value (SBGWd) for operation in the dynamic or unsteady state such as acceleration and deceleration is stored in a second characteristic field (22). These basic values are dependent on desired injected fuel quantity (Q) and engine speed (n). The characteristic field (20) for the static state is designed empirically or otherwise to optimize fuel consumption whereas the characteristic field (22) for the dynamic state is designed for minimum pollutant emission. A gradual changeover from one mode to the other is achieved by the gradual change of a multiplying factor (c) from 0 to 1 or vice versa responsively to dQ/dt departing significantly from zero or becoming zero.
