A heat feeding apparatus employable for an internal combustion engine having a supercharger attached thereto, the apparatus including a compressed air bypass passage opening/closing valve disposed midway of a compressed air bypass passage by way of which the outlet of a blower is communicated with the inlet of a turbine in the supercharger and combustion means installed in an inlet region of the turbine, wherein opening or closing of the compressed air bypass passage opening/closing valve and combustion in the combustion means are initiated in dependence on the temperature of a specific kind of medium for which heat exchanging is effected in a heat exchanger, whereby a heat involved in the exhaust gas is transmitted to the heat exchanger in dependence on the demand required by the medium.

A heat feeding apparatus comprising an internal combustion engine having a supercharger, said supercharger including a blower and a turbine each having an associated inlet and outlet, said combustion engine including a combustion chamber having an inlet and outlet, a first conduit connected between said blower outlet and said combustion chamber inlet for conducting compressed air from said blower to said combustion chamber, a second conduit connected between said combustion chamber outlet and said turbine inlet for conducting hot gasses from said combustion chamber to said turbine inlet, a bypass passage between said first and second conduits, a valve for opening and closing said bypass passage whereby in an open position of said valve compressed air from said blower is conducted through said bypass passage to said turbine inlet via said second conduit, combustion means between said valve and said turbine inlet for injecting fuel into the compressed air in said bypass passage, means for igniting said injected fuel and compressed air, means for effecting a heat exchange between a heat exchange medium and hot gasses exiting the turbine via the turbine outlet, means for detecting the temperature of the heat exchange medium; and means for responding to a detected first predetermined temperature of the heat exchange medium for closing said valve, and further responsive to a detected second predetermined temperature lower than said first predetermined temperature for opening said valve and operating said ignition means for igniting said fuel.
