METHOD (VARIANTS) AND ENGINE CONTROL SYSTEM Russian patent published in 2018 - IPC F02M25/25 F02P5/15 F02D41/30 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the internal combustion engines, in particular, for the spark plugs operation and the combustion chamber state improvement by means of water injection. Proposed are soot on the spark plug accumulation and soot accumulations in the combustion chamber reduction methods and systems by the spark plug ignition timing control during the squirter water or liquid injection. For example, the squirter water or liquid is injected during the torque reduction by using the ignition timing so, that to provide at least the partial torque reduction with the soot from the spark plug and from the combustion chamber timely removal. By reducing the soot accumulation on the spark plug reducing the misfiring in the cylinder probability, and by the combustion chamber cleaning of the carbon deposits reducing the early ignition likelihood.

EFFECT: technical result consists in reduction of the spark plugs soot contamination and reduction in the misfiring probability.
