DEVICE FOR CONTROL OF INJECTION INTO INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: each cylinder has a hydraulically controlled nozzle connected with a high pressure fuel pump through a fuel pipe line. Each pipe line has a branch pipe connected to the low pressure space through a valving member. The device has power source connected to the common bus of a voltage generator through the first switch and electric signal pickup. The generator is kinematically coupled with the shaft of the engine. The pickup is constructed as two coaxially mounted rotors which are coupled with the engine shaft immediately and through phase-mixer and interact with contacts the number of which is equal to the number of the cylinders. The phase-mixer is made up as an integrating mechanism and coupled with the control member. Each of the contacts of the member is connected to the corresponding valving member in series through a multi-vibrator and amplifier whose second inputs are connected to the power source. The voltage generator is connected with the rotors through the switch having two inputs and three working position. The generator is connected to the first rotor through variable resistor and logical element AND. The generator is connected with the second rotor through a logical element which is similar to the AND element. The first rotor is coupled with the power source through the third switch. EFFECT: enhanced reliability. 4 cl, 1 dwg
