F02M31/08 - CPC Classification

Classification description:

Apparatus for thermally treating combustion-air, fuel, or fuel-air mixture for heating combustion-air or fuel-air mixture by hot gases, e.g. by mixing cold and hot air the gases being exhaust gases

Sub-classes:

F02M31/0805 » {Pneumatic control of the amount of exhaust gas or combustion air directed to the heat exchange surfaces e.g. as a function of the pressure in the air intake passage} 0
F02M31/081 » {Manual switching of the fluids directed to the heat exchange surfaces} 0
F02M31/0815 » {Heat exchange surfaces arranged inside a flange} 1
F02M31/082 » {Particular shape of air input passage near to the branch} 0
F02M31/0825 » {Particular constructional characteristics of the heat exchange surfaces, e.g. finned pipes, coiled pipes or the like} 9
F02M31/083 » Temperature-responsive control of the amount of exhaust gas or combustion air directed to the heat exchange surface 9
F02M31/087 » Heat-exchange arrangements between the air intake and exhaust gas passages, e.g. by means of contact between the passages 23
