FIELD: engines and pumps.
SUBSTANCE: invention relates to automotive industry. Note here that reducer is used for neutralisation of ICE exhaust gases. Simple means are used to inform the ICE control unit about quality of reducer contained in said appropriate tank. For this the steps that follow are applied. Amounts of reducer filled in the tank and forced therefrom are defined and recorded with the help of level transducer during the entire life of exhaust gas neutraliser. Reducer temperature in tanks is defined and recorded by appropriate transducer during the entire life of exhaust gas neutraliser. Ultrasound wave propagation rate in reducer is defined and recorded by ultrasound transceiver. Reducer state in control unit is defined by above said parameters.
EFFECT: efficient cleaning of exhaust gases.
