FIELD: machine building.
SUBSTANCE: invention can be used in automotive internal combustion engines. Method for engine comprises determining composite temperature of exhaust gases in unstable mode based on duration of switching on heater of exhaust gas sensor, as well as based on operating conditions of vehicle in transient mode, such as engine load, vehicle speed and temperature at exhaust flange. Operation of engine is controlled based on composite temperature of exhaust gases in unstable mode. Disclosed is embodiment of method for vehicle engine.
EFFECT: technical result is higher accuracy of estimating temperature of exhaust gases.
