To provide a suitable number of display fields (e.g. ARRIVAL; TIME; etc.), each of which characterizes and identifies the significance or import or meaning of a displayed numerical value on a display device (16), the display fields are associated in groups or sets (11-15; 42-45) having a particular geometric position (columns; segmental), and a plurality of keys (21-25) are provided with each key being associated with a group or set of the display fields, and connected to a counter (61) to select a particular one of the display fields within the group or set by the number of key operations, the numerical value associated with the display field then being displayed on the numerical display (16). The display and keys are connected to a computer (62) which provides the output data for the numerical indicator (16); an input/output control switch (26) is provided to change the function of the display group selection keys (21-25) to permit data entry into the computer (62), for example of speed limit, driving distance, and the like.

Injected into an internal combustion engine are fed pulses via a gate which starts to transmit when the crank shank of the engine is in a particular angular position and stops the transmission when the number of pulses applied to the injectors is equal to a number determined as a function of various operating parameters of the engine. The injectors remain open while pulses are being applied and close when the gate closes.

Injection control system for an internal combustion engine

Injectors in an internal combustion engine are fed pulses via a gate which starts to transmit when the crank shaft of the engine is in a particular angular position and stops the transmission when the number of pulses applied to the injectors is equal to a number determined as a function of various operating parameters of the engine. The injectors remain open while pulses are being applied and close when the gate closes.
