    • An apparatus and method for supplying a predetermined volume of liquid fuel (20) to a cylinder of a diesel engine (10) is provided. A storage tank (22) stores a column of the liquid fuel (20) in a storage area (24). A position sensor (36) transmits an analog signal proportional to the height of the fuel (20) in the tank (22). A pressure transducer (32) disposed at the bottom of the storage area (24) transmits an analog signal corresponding to the static fluid pressure at the bottom of the storage area (24). A temperature transducer (56) disposed along a fuel rail (16) transmits an analog temperature signal to an electronic fuel injection computer (14). The computer (14) converts the analog height signal, the analog temperature signal and the analog pressure signal into digital values and mathematically divides the resulting digital values of height and pressure to obtain a digital value for the fuel density. A programmed ROM (72) of the computer (14) produces an output binary signal representative of a predetermined viscosity based on the instantaneous values of the temperature and the density of the fuel (20) over a range of values of the density and the temperature. The ROM (72) generates a three-dimensional surface representing values of viscosity based upon the temperature and the density. The output binary signal of the ROM (72) is used by the computer (14) through a diesel output control (11) to control a metering solenoid (13) of a fuel injector (12) which injects fuel into a cylinder of the engine (10).

    • An electronic control apparatus for a fuel injection system in internal combustion engines which has a timing device for the generation of electric injection pulses, whose duration is dependent on operating characteristics and which are delivered to at least one electromagnetic injection valve which includes a time control circuit associated with the timing device in order to form at least one limiting value for the subsequent injection pulse and the subsequent injection pulse as well as the at least one limiting value can be delivered to a selector circuit so as to limit variations with respect to the duration of the injection signal thereby achieving smooth operation of the internal combustion engine. On the basis of an injection pulse at time tn, limiting values are formed for the duration of the subsequent injection pulse, and the next subsequent injection pulse at time tn+1 is kept within the limiting value which has been generated, it being particularly favorable to form the electronic control apparatus using digital structural elements, by means of which not only a high degree of precision and reliability but also an easy adaptation to other digital systems is obtained.

    • A fuel injection system for an internal combustion engine employs a relatively low pressure pump to provide fuel to injectors located at the engine cylinders. A booster device for maintaining the fluid pressure constant, at a substantially higher level, is connected in series with the line between the pump and the injector and includes one way valves at its inlet and outlet. The booster employs a chamber connected to the fuel line and pressurized by a piston which acts to contract the chamber volume under the force of the coil spring. The piston is cocked against the spring at regular intervals to renew the original volume of the chamber by an arm driven from the engine crankshaft. Sealed volume converters having flexible diaphragm walls are disposed adjacent to the inlet and outlet of the booster device and in the fluid conduit adjacent the injectors to obviate sharp drops in the fluid pressure in the fuel line when the injectors actuate.

    • A plurality of sensors generate signals representing engine parameters indicative of the engine fuel requirement. These signals are all applied to a single function generator to form a composite signal that is a nonlinear function of the engine fuel requirement. One of the sensors responds to absolute intake manifold pressure; responsive to this sensor, operation is inhibited, while the absolute intake manifold pressure is below a predetermined value representative of engine deceleration. An engine starter switch generates a trigger pulse to actuate an overriding multivibrator that overrides normal operation as the engine is started. One of the sensors also responds to engine coolant temperature; responsive to this sensor, the actuation duration of the overriding multivibrator is controlled in reverse relation to the coolant temperature. A manual switch, which generates a trigger pulse responsive to closing, is coupled to the overriding multivibrator to with actuate it responsive to each trigger pulse generated by the switch.
