Automobile fuel pretreatment device

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
• two spring clamp boards, which enclose and clamp an insulation assembly formed of the insulation sheet wrapping around the two plate electrodes and the electric thermal ceramic element on the fuel tube, each of the spring clamp boards 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 of each of the spring clamp boards being received through the locking hole of the other one of the spring clamp boards and folded back under plastic deformation to resiliently and overlappingly engage the first free end of said the other one of the spring clamp boards;
• 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.
