Abstract
The utility model discloses a kind of spark plugs of lateral electrode orientation, comprising: spark plug body；Lateral electrode is arranged on spark plug body；External screw thread is arranged on spark plug body；Atomizer, spark plug body and atomizer are installed on engine cylinder body；Externally threaded screw thread stop is fixed on thread periphery direction with the relative position of lateral electrode；When spark plug body and atomizer are mounted on engine cylinder body, lateral electrode face atomizer has good promotion to the oil atomizing effect of fuel injector.
Description
Technical field
The utility model belongs to the spark plug of technical field of automobile engine more particularly to a kind of lateral electrode orientation.
Background technique
In the process of implementing the utility model, the inventor finds that the existing technology has at least the following problems: with discharge
Regulation is more harsh, also higher and higher for the technical requirements of petrol engine, to enable fuel oil more fully to burn, mesh
The main engine plants of preceding mainstream turbocharging technology all in research and development cylinder, when fixed using spark plug, due to process aspect, fire
The stop of flower plug screw thread will not be forced on specific position, and during installation, meeting spark-plug side electrode may be led backwards to fuel injector
Cause atomizing effect after fuel injector oil spout bad.
Utility model content
The technical problem to be solved by the utility model is to provide the oil atomizing effects of a kind of pair of fuel injector to have well
The spark plug of the lateral electrode orientation of promotion.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the utility model is a kind of fire of lateral electrode orientation
Hua Sai, comprising:
Spark plug body；
Lateral electrode is arranged on the spark plug body；
External screw thread is arranged on the spark plug body；
Atomizer, the spark plug body and atomizer are installed on engine cylinder body；The externally threaded screw thread stops
Relative position of the point on thread periphery direction with the lateral electrode is fixed；When spark plug body and atomizer are mounted on engine
When on cylinder body, atomizer described in the lateral electrode face.
It further include washer, the washer is sleeved on the external screw thread.
On thread periphery direction, the externally threaded screw thread stop is overlapped with the lateral electrode.
A technical solution in above-mentioned technical proposal has the following advantages that or beneficial effect passes through screw thread during installation
The position of stop determines the position of lateral electrode, guarantees the position of side electrode spark plug against fuel injector, to the oil spray of fuel injector
Changing effect has good promotion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the spark plug of the lateral electrode orientation provided in the utility model embodiment；
The mounting structure schematic diagram for the spark plug that the lateral electrode that Fig. 2 is Fig. 1 orients；
Label in above-mentioned figure is equal are as follows: 1, spark plug body, 2, lateral electrode, 3, screw thread stop, 4, washer, 5, atomizer.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Referring to Fig. 1-2, a kind of spark plug of lateral electrode orientation, comprising:
Spark plug body；
Lateral electrode is arranged on spark plug body；
External screw thread is arranged on spark plug body；
Atomizer, spark plug body and atomizer are installed on engine cylinder body；Externally threaded screw thread stop is in screw thread
It is fixed in peripheral direction with the relative position of lateral electrode；When spark plug body and atomizer are mounted on engine cylinder body, side
Electrode face atomizer.
It further include washer, washer is sleeved on external screw thread.
On thread periphery direction, externally threaded screw thread stop is overlapped with lateral electrode.
Spark-plug thread dead-centre position, which reaches, to be required, while must also guarantee that cylinder cap spark plug mounting hole internal screw thread originates point
It sets on a certain position, it will guarantee that the position of side electrode spark plug against fuel injector, reaches expected atomization to a certain extent
Effect.
After above-mentioned structure, during installation, the position of lateral electrode is determined by the position of screw thread stop, guarantee side electricity
There is good promotion in the position of polar spark plug against fuel injector, to the oil atomizing effect of fuel injector.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change
Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model
Protection scope within.
