の作動を正常に行うようにしである。Generally, fuel with relatively high viscosity, such as @oil 1 heavy oil, is used as fuel for diesel engines. By the way, for these fuels, not only the heptane number, which evaluates the fuel wa properties, but also the pour point, cloud point, etc., which evaluate the fluidity of the fuel, are
It is specified in IS. Therefore, diesel fuel is differentiated and used depending on the environment in which it is used (% and outside temperature). For example, No. 2 diesel oil is used when the outside air is up to -60, and No. VIs diesel oil is used when the outside air is -aoct, to ensure normal engine operation.

する。However, in recent years, the resistance of the fuel piping system has become high due to the use of mixed fuel for long-distance driving and the use of a distributor injection pump to reduce the resistance of the fuel piping system. As a result, there is a tendency for the engine to start frequently when the diesel engine is malfunctioning. It has become clear that the main cause of this engine malfunction is that paraffin in the fuel precipitates due to the use of diesel fuel at low temperatures and clogs the fuel filter. Therefore, as a countermeasure against this clogging, it is possible to dissolve the precipitated paraffin, but the most effective way to dissolve this paraffin is to heat the fuel itself.
The paraffin also flows out due to heating, causing engine problems.

燃料加熱装置４を提供するものである。The present invention takes into consideration the conventional situation and provides a fuel filter with a heater unit for heating the fuel in the fuel filter, thereby preventing the precipitation of paraffin in the fuel and preventing the precipitation of paraffin in the fuel filter. The purpose of the present invention is to provide a fuel heating device 4 which melts the fuel and promotes normal operation of the engine.

A head cover 1 is attached to the upper end of the head via a threaded part.
It consists of 1. The filter body 10 has an inner cylinder 1
2 and an outer cylinder 13, and a filter element 14 made of F paper, F cloth, etc. is disposed inside and between the outer cylinders 12 and 13. On the other hand, the head cover
11 is formed with a fuel inlet 15 and an outlet 16, the inlet 15 is connected to the fuel supply pump 8 via a pipe 7, and the outlet 16 is connected to the injection pump 6 via a pipe 8. It has become so. The fuel introduced from the intake port 15 then reaches the filter element 14 through passages 17,18.

内に収納されている。Here, one aspect of the present invention is that the fuel filter 4 has a built-in Kk-taper unit 30. That is, the heater unit detects the temperature inside the heater body 31 inserted into the inner cylinder 12 from the lower end of the outer cylinder 13 and the fuel filter 4, @Temperature sensor 32 for controlling the temperature and these - evening body 3! , Onbase/
111yII at the lower end of the outer cylinder 13.
It is composed of a glove 33 that is The heater body 31 is formed of an electric heating element such as a nichrome wire, and has a cylindrical body U that separates the heater body 31 from the fuel in the fuel filter 4.
It is stored inside.

で、燃料が過加熱されることはない。With the above configuration, when the heater main body 31 is energized, the heater main body 31 generates heat, and the fuel in the fuel filter 4 is heated. Then, the paraffin precipitated in the fuel at low temperature is dissolved, and the precipitated paraffin adhering to the filter element 14 is also dissolved, increasing the amount of fuel passing through the filter element 14, that is, passing through the fuel piping system. The amount of heat generated by the heater unit 30, which normalizes the fuel and operates the diesel engine normally, is controlled based on the detected value of the temperature sensor 32, so that the fuel is not overheated. It will not be done.
ところで、前述し九ヒータユニット３０のヒータ本体３

ことはいうまでもない。By the way, the heater body 3 of the nine heater units 30 mentioned above
1 uses an electric heating element, but it is needless to say that the invention is not limited to this and that other means of generating heat may be used.

という優れ九効果を有する。As explained above, the engine fuel heating device of the present invention has a fuel filter K disposed in the fuel piping system of the engine.
Since the fuel filter has a built-in heater unit for heating the fuel, it dissolves the paraffin precipitated in the fuel at low temperatures, and also dissolves the precipitated paraffin adhering to the filter element. This has the advantage of normalizing the fuel passage and normalizing the engine operation.
