FUEL FEED ELECTRONIC CONTROL SYSTEM Russian patent published in 2011 - IPC F02D41/30 

FIELD: engines and pumps.

SUBSTANCE: proposed system comprises electronic control unit, power switch unit, rpm converter and transducers, camshaft timing mark converter made to synchronise system operation with that of engine cylinders. Electronic control unit comprises power amplifier, protection device, controller, interface an indicator, all arranged in single case, interconnected and connected with external circuits by connector assemblies. Electronic control unit input is connected to rpm converter output while its output is connected to power switch unit input that incorporates base of transistors and allows generation of difference signal to be distributed among output power switches in order of cylinders operation and electromagnets that control operation of valves, or to computer-aided control system. Connector assemblies to power amplifier connection as well as for connection of electronic control unit controller with external circuits may be arranged on one side of control unit case together with three fuses.

EFFECT: higher efficiency and reliability.
