A vehicle self-ignite alarming apparatus comprises a triode, wherein an emitting electrode of the triode is connected to a positive electrode of a power source; a collector electrode of the triode is connected to the power source positive electrode after the collector electrode is in serials connection with a thermal-sensitive electric resistor; a base electrode of the triode is connected to a negative electrode of the power source after the base electrode of the triode is in serials connection with a first electric resistor; a second electric resistor is also parallelly connected between the base electrode and the collector electrode of the triode; two ends of the first electric resistor are respectively connected to two input ends of a signal regulating circuit; an output end of the signal regulating circuit is connected to a displayer; and an alarming output end of the signal regulating circuit is connected to an alarming device. When the temperature of the thermal-sensitive resistor is changed, the electric current flowing through the two ends of the first electric resistor will also changed and the voltage at the two ends of the first electric resistor; the signal regulating circuit receives voltage signals at the two ends of the first electric resistor and the signals are outputted after the signals are processed, which signifies that the electric signals of the temperature in an engine compartment is displayed by a displayer; and when the temperature in the engine compartment exceeds the preset signals, the output alarming signals are controlled by the signal regulating circuit to give out alarm.
