INTERNAL COMBUSTION ENGINE CONTROL SYSTEM Russian patent published in 2008 - IPC F02D43/00 F02P5/00 F02P11/04 B60R25/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to internal combustion engine control systems. The proposed internal combustion engine control system includes TDC mark 1 made on teeth plate 2 fitted on the engine shaft, sensitive pickup 3 coupled with control unit 4. Note that mark 1 is made on plate 2 with angular shift relative to point 5 on plate 2 corresponding to an actual position of the engine piston at TDC. The circuit between pickup 3 and control unit 4 incorporates input pulse generator 6, processor 7, output pulse generator 8. Processor 7 is furnished with access control unit 9. Processor 7 incorporates also multiplex bus 10 with multiplexer 11 to connect service devices 12 (for example, shock pickup, passenger compartment inside scanning pickup, microwave motion pickup etc). Processor 7 includes data I/O interface allowing the connection of additional service devices to the said processor. For example, PC 13 incorporating an appropriate engine diagnostics software allowing estimating the engine state staying inside the cab. Access control unit 9 represents an electronic lock with a dynamic cryptocode.

EFFECT: higher safety internal combustion engine control system prohibiting unauthorised starting of the engine.
