Abstract: PURPOSE: To restrain discharge of toxic substance and stabilize combustion in a burner type vehicle auxiliary heating device by deciding air ratio based on the flame temperature measured in a combustion chamber. CONSTITUTION: The sensor 10 of a flame temperature detecting device 8 is arranged in a combustion chamber 2, extendingly provided from the flame root to the extreme end part of the flame, and detects the flame temperature and inputs to a device 9. The device 9 obtains the air ratio λ from a graph indicating relation of the flame temperature and the air ratio. By the air ratio λ, the ratio of an air quantity supplied to a burner 3 to the fuel quantity supplied to it is controlled. By this constitution, the discharge quantity of toxic substance can be restrained and combustion can be stabilized.
