UNIT CONTROLLING INJECTION OF FUEL INTO INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: internal combustion engines. SUBSTANCE: proposed unit has first former which input is connected to transmitter of top dead point and which output is linked to unit measuring rotation speed and control unit, second former which input is connected to transmitter of angular pulses and which output is linked via time interval unit to analog-to-digital converter, third former which input is connected to transmitter of air flow rate. Output of unit measuring rotation speed is connected to microprocessor which output is connected via power amplifier to fuel batchmeter. Unit is supplemented with functional code-to-code converter, code adder and code divider. Output of analog-to-digital converter is connected via code-to-code converter to code adder which output is connected to code divider to second input of microprocessor. Output of third former is connected to second input of analog-to-digital converter. Output of time interval unit is connected to second inputs of functional code-to-code converter and code adder. First output of control unit is connected to third input of code adder, second output of control unit is connected to second input of code divider. EFFECT: increased efficiency of control over injection of fuel. 2 dwg
