Description
Technical Field
The utility model relates to an automobile spare and accessory part field, concretely relates to preheating device and engine admit air.
Background
As shown in figure 1, the whole area of the existing preheating device is small, air can be dispersed after passing through the preheating device, and the preheating device is further away from a cylinder opening. In this case, a plurality of times of heating are required, even in a one-by-one manner, so that the engine is just started, but the engine is damaged, and the service life is shortened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the defects of the prior art are overcome, the air inlet preheating device and the engine are provided, and the problems that the whole area of the air inlet preheating device is small, air after preheating is easy to disperse, and the engine cannot be normally started are solved.
The utility model provides a technical scheme that its technical problem adopted is:
in a first aspect:
an intake air preheating device comprises
The heating device comprises a shell, a plurality of air inlets are formed in the middle of the shell, heating wires are installed in the air inlets, and the heating wires are electrically connected in series;
a plurality of mounting holes are formed in the periphery of the shell and are suitable for fixing the shell on an air inlet of an engine, so that the heating wire is embedded in an opening of a cylinder of the engine.
Furthermore, two sides of the air inlet are provided with convex supporting bodies, the heating wire is arranged on the two supporting bodies, and the supporting bodies are positioned on one side of the shell facing the engine when the shell is installed;
an installation step is formed between the pool supporting body and the shell.
Furthermore, all the heating wires are connected to form a heating wire group, and the positive electrode of the heating wire group is connected with a metal jumper wire.
Further, the number of the air inlets is 4.
Furthermore, the shell is provided with a grounding wire.
In a second aspect:
an engine comprises an engine body, wherein the cylinder opening of the engine body is provided with the intake preheating device.
The utility model has the advantages that:
the utility model discloses a preheating device and engine admits air, can be embedded in the jar mouth inboard during installation, lie in near jar mouth, carry out the bulk heating to whole jar mouth and near, reach balanced effect.
The air inlet preheating device is additionally provided with a plurality of air inlets, the air inlet of the engine is preheated in a distributed mode, the preheating efficiency is improved, the starting time of the engine is shortened, the engine is combusted fully, and the emission of harmful substances is reduced.
The engine has the advantages that the whole internal part of the engine can achieve a good balance effect, the engine can be started rapidly and smoothly in a harsh environment, multiple times of starting are not needed, and the abrasion of the engine is effectively reduced.
In addition, the preheating mode of the invention also enables the engine to be fully combusted during starting and in the starting process, and reduces the generation of white smoke, thereby meeting the emission standard of the environment.
The positive pole wire jumper has been increased, and in actual conditions, because this preheating device is embedded in the cylinder body, the space is narrow and small limited, and the sight is also not touching that can be fine, leads to instrument and manual work can't lock the part of inside and dies, the design of the positive pole wire jumper mentioned in the utility model, the effectual engine of having solved is at the in-service behavior, because the too big part that brings of vibration is not hard up the phenomenon, has also prevented the inefficacy of part.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of a conventional intake air preheating device;
FIG. 2 is a schematic view of the intake air preheating device of the present invention;
the heating wire comprises a shell 1, a shell 2, a heating wire 3, a supporting body 4, a metal jumper wire 5, a mounting hole 6 and a grounding wire.
Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Example one
As shown in FIG. 2, an intake air preheating device includes
The heating device comprises a shell 1, wherein a plurality of air inlets are formed in the middle of the shell 1, heating wires 2 are installed in the air inlets, and the heating wires 2 are electrically connected in series;
a plurality of mounting holes 5 are formed in the periphery of the shell 1 and are suitable for fixing the shell 1 to an air inlet of an engine, so that the heating wire 2 is embedded in an opening of a cylinder of the engine.
