FIELD: engines and pumps.
SUBSTANCE: internal combustion engine control system incorporates combustion chamber area-to-volume ratio variator and device to detect parameter other than hydrogen concentration with output magnitude varying subject to hydrogen concentration of exhaust gas increasing with increase in said ratio. ICE is controlled by said output magnitude of said detector. Output magnitude of said detector or parameter related with ICE operation is corrected in compliance with aforesaid ratio set by aforesaid ratio variator.
EFFECT: better fuel combustion.
