FIELD: engines and pumps.
SUBSTANCE: present invention relates to device and method of controlling internal combustion engine with spark ignition, equipped with pressure sensor in cylinder. Device comprises electronic control unit (ECU) (20), which after beginning of cranking engine controls so that first combustion cycle run in cylinder equipped with pressure sensor (step 100). After that self-ignition occurs in first cycle and varying pressure in cylinder. ECU (20) detects change of pressure in cylinder with help of sensor (22) of pressure in cylinder and receives its maximum value in form of value Pmax (step 102). Then obtained value Pmax is corrected based on cooling liquid temperature and amount of air in cylinder (step 104). ECU (20) stores information on relationship between value of Pmax and octane number (RON) in form of card. ECU (20) determines octane number (RON) corresponding to derived value Pmax from this card (step 106).
EFFECT: technical result is determination of characteristics of fuel based on detected pressure change in cylinder prior to start.
