Description

Technical Field

[0001] This utility model relates to the field of fuel injector technology, and more specifically to a fuel injector holder with a preheating rod mounting structure. Background Technology

[0002] Fuel-fired heaters are mainly used in buses, coaches, trucks, and special-purpose vehicles. They rely on diesel fuel to preheat the engine in the workshop and for heating the driver's cab.

[0003] However, in existing technologies, ignition failures can occur in the heaters. One of the main reasons for this is that the diesel fuel at the injector becomes more viscous or even waxy in cold weather, which prevents the diesel fuel from being properly atomized and ultimately leads to ignition failure of the fuel heater. Utility Model Content

[0004] In view of this, the present invention provides a fuel injector seat with a preheating rod mounting structure, the purpose of which is to solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A fuel injector holder with a preheating rod mounting structure includes: a base; a fuel injector on the top of the base; a heating seat on the outer side of the base; and an electric heating rod inside the heating seat.

[0007] Preferably, the heating base has a through heating groove inside; the electric heating rod is inserted into the heating groove.

[0008] Preferably, a threaded hole communicating with the heating groove is provided on the outer wall of the heating seat; a fastening bolt is threaded into the threaded hole.

[0009] Preferably, the heating base has a cylindrical structure.

[0010] Compared with the prior art, the present invention achieves the following technical effects: The present invention heats the fuel at the fuel injector by using an electric heating rod, so that the fuel is well atomized after being injected, thereby ensuring the successful ignition of the fuel heater.

[0015] Example

[0016] Reference Figure 1-2 As shown, this utility model discloses a fuel injector holder with a preheating rod installation structure, including: a base 1; a fuel injector 2 is provided on the top of the base 1, and fuel is supplied to the fuel injector 2 through the internal oil passage of the base 1; a heating seat 3 is provided on the outer side of the base 1; an electric heating rod 4 is provided inside the heating seat 3; in use, the fuel at the fuel injector 2 is heated by the electric heating rod 4, so that the fuel is well atomized after being sprayed out, thereby ensuring the successful ignition of the fuel heater.

[0017] In this embodiment, a through heating groove 5 is provided inside the heating base 3; the electric heating rod 4 is inserted into the heating groove 5, which facilitates the installation and removal of the electric heating rod.

[0018] In this embodiment, a threaded hole communicating with the heating groove 5 is provided on the outer wall of the heating base 3; a fastening bolt 6 is threadedly connected in the threaded hole; in use, the electric heating rod 4 is inserted into the heating groove 5, and then the fastening bolt 6 is tightened to fix the electric heating rod 4 in the heating groove 5. When it is necessary to remove the electric heating rod 4, the fastening bolt 6 is loosened and the electric heating rod 4 is pulled out.

[0019] In this embodiment, the heating base 3 is a cylindrical structure.

[0020] In this embodiment, a boss is provided on the outer wall of the heating seat 3; a threaded hole is opened in the middle of the boss.

[0021] In this embodiment, the boss and the heating base 3 are an integral structure.

[0022] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
