Abstract

Una unità di controllo (12) è destinata a controllare l'apertura e la chiusura di una valvola di iniezione di acqua (11) disposta su un condotto di iniezione di acqua (1) che è collegato ad un condotto di scarico (2). L'unità di controllo (12) applica il segnale di apertura della valvola sotto la condizione predeterminata in risposta ad una frequenza di rotazione (NE) e un grado di apertura della farfalla (?TH), che sono applicati da un sensore di rotazione (8) e da un sensore della farfalla (16), rispettivamente, e apre la valvola di iniezione di acqua (11) permettendo che il condotto di iniezione di acqua (10) inietti acqua nel condotto di scarico (2). L'iniezione di acqua nel condotto di scarico (2) serve per diminuire la temperatura del gas di scarico nel condotto di scarico (2) riportando la condizione di pulsazione di pressione alla condizione di compatibilità. Come risultato, la diminuzione della potenza di uscita nella zona di velocità bassa ed intermedia può essere migliorata e nello stesso tempo è possibile migliorare la durata del sensore oltre che la risposta del controllo con l'aiuto di un grado di apertura della farfalla (?TH).A control unit (12) is designed to control the opening and closing of a water injection valve (11) arranged on a water injection conduit (1) which is connected to a discharge conduit (2). The control unit (12) applies the valve opening signal under the predetermined condition in response to a rotation frequency (NE) and a butterfly opening degree (? TH), which are applied by a rotation sensor ( 8) and a throttle sensor (16), respectively, and opens the water injection valve (11) allowing the water injection conduit (10) to inject water into the discharge conduit (2). The injection of water into the exhaust pipe (2) is used to decrease the temperature of the exhaust gas in the exhaust pipe (2), returning the pressure pulsation condition to the compatibility condition. As a result, the decrease of the output power in the low and intermediate speed zone can be improved and at the same time it is possible to improve the duration of the sensor as well as the response of the control with the help of a degree of opening of the throttle (? TH ).
