Patent ID: 8474441

Claim:
An automobile fuel pretreatment device, comprising: an instantaneous constant-temperature heating device, which comprises: a fuel tube which is adapted to allow fuel to flow therethrough, a heating unit, which comprises at least two plate electrodes arranged on an outside surface of the fuel tube, at least one electric thermal ceramic element interposed between the two plate electrodes, at least one insulation sheet wrapping around the two plate electrodes and the electric thermal ceramic element, and two power cables respectively supplying electrical current to the two plate electrodes, the two plate electrodes transmitting the electrical current to the electric thermal ceramic element for heating the fuel tube, and a spring clamp board, which circumferentially encloses and clamps an insulation assembly formed of the insulation sheet wrapping around the two plate electrodes and the electric thermal ceramic element on the fuel tube, the spring clamp board comprising a locking hole formed adjacent to a first free end and a locking tab formed adjacent to a second free end, the locking tab being received through the locking hole and folded back under plastic deformation to resiliently and overlappingly engage the first free end; and a magnetization combustion-enhancing device, which comprises at least one permanent magnet that is located adjacent to an outside surface of the fuel tube to induce magnetization on the fuel flowing through the fuel tube.
