Failure alarm system of automobile exhaust system

摘要

This high case is about the fault alarm device of automobile exhaust system, which is installed in the pressure sensor of automobile exhaust gasStarting from the above pressure sensor (1), if the pressure signal is larger or the same as the standard pressure signal, the signal will be printed,A comparator (2) and a channel (low) output signal from the pressure sensor (1) to which the pressure signal is smaller than the standard pressure signal;According to the output signal of the comparator (2), an alarm (3) for displaying an alarm is formed,In the exhaust system of automobile,In particular, if there is a defect that triggers the inverter or scarf, an increase in the pressure of the exhaust gas will be detected and an alarm will be given,Quickly eliminate the failure of exhaust device,Therefore, the engine output has the effect of preventing the decline.
