8.2.3. The gauge of concentration of oxygen in the fulfilled gases (ДКК)
The gauge of concentration of oxygen in the fulfilled gases
ДКК it is established in the final pipeline and it is washed by a stream of the fulfilled gases. Depending on the oxygen maintenance in the fulfilled gases pressure of a signal of the gauge changes. Pressure of a signal can change from 0,1 In (the high maintenance of oxygen – poor топливовоздушная a mix) to 0,9 In (the low maintenance of oxygen – rich топливовоздушная a mix). It is possible to measure pressure of signal ДКК by the digital voltmeter with full resistance not less than 10 мОм. Use of the usual voltmeter will give the big error of measurement. Constantly supervising pressure of signal ДКК, ECU develops commands of correction of quantity of fuel injected into the inlet pipeline. At a low voltage of signal ДКК (poor топливовоздушная the mix) ECU increases gasoline giving, at a signal high voltage (rich топливовоздушная a mix) – fuel giving decreases. At rupture of an alarm wire of DKK ECU establishes a code of malfunction 13. In case of constant low or a high voltage of signal ДКК the code of malfunction 44 or 45 is established accordingly. Codes 44 and 45 can be established also at malfunctions of system of injection of fuel. The prevention To remove or disconnect
