FIELD: engines and pumps.
SUBSTANCE: control unit for internal combustion engines (ICE) is proposed, including the first detection unit, detecting the injector nozzle tip temperature as the first parameter and the second detection unit, detecting the heat amount of the cylinder head as the second parameter. The control unit determines whether there will be a condensate on the tip of the injector nozzle after turning off the ICE, by using at least one of the first parameter and the second parameter. The control unit includes the third detection unit which detects an estimated value, which allows to evaluate the state of ICE and compares the estimated value with a threshold value for selecting which parameter from the first parameter and the second parameter is selected to determine condensation at the nozzle tip.
EFFECT: reduced computing load of the control unit and increased accuracy of rust detection of injector nozzle.
