The invention discloses an automatic
temperature control heating device of a diesel vehicle fuel
system, belongs to the technical field of accessories of a motor vehicle fuel
system, and solves automatic
temperature control heating for fuel. Electric heaters which can independently and automatically control the temperature respectively and have automatic safety protection function are assembled at the corresponding parts of a fuel
system; the heating device comprises a fuel
pipe inner heater, a filter and an
oil tank inner heater, wherein the fuel
pipe inner heater consists of an
electric heating wire L, a thermal fuse RD1 and a bimetallic temperature controller ZK1 which are connected in series together and form a whole through injection molding and packaging; and the filter and the
oil tank inner heater form a whole through a heat-sensitive resistance heating sheet and the bimetallic temperature controller which are connected in series together. The heating device has the advantages that the heating device not only can solve the problems that a diesel vehicle is difficult to start and easy to
shut down during running, but also can keep the temperature of the diesel supplied to an engine by the fuel system between 7 and 24 DEG C all the time, realizes year-round use of No.0 diesel oil, has high fuel heating speed, high efficiency and reliable safety protection function, can improve filter precision and reduce
oil consumption and
discharge, is convenient for a user to assemble and use the heaters for the fuel system parts as required in a single mode, a combined mode or a full system mode according to different vehicles and different seasons, and simultaneously is quite convenient to use.
