Full Title

Full titles differ between systems:

IPC:

Apparatus for thermally treating combustion-air, fuel, or fuel-air mixture > for heating > electrically

CPC:

Apparatus for thermally treating combustion-air, fuel, or fuel-air mixture (carburettors with heating, cooling or thermal insulating means for combustion-air, fuel or fuel-air mixture F02M15/00; apparatus for de-liquefying non-liquid fuels by heating F02M21/06; apparatus having heating means for non-gaseous fuels with low melting point F02M21/10; apparatus characterised by adding hot secondary air to fuel-air mixture F02M23/14; fuel-injection apparatus characterised by having heating, cooling or thermally insulating means F02M53/00) > for heating ( for purifying liquid fuel F02M37/30) > electrically

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1990.
