Abstract
The utility model relates to an ignition coil of an engine, in particular to an overhead type ignition device. The overhead type ignition device comprises a top portion and a neck portion, the top portion is provided with the ignition coil, mounting holes and a connector socket, the neck portion is matched with the mounting holes on a cylinder body, the neck portion is made of polyurethane (PU) rubber, a spark plug is arranged inside the neck portion, an input end of the ignition coil is connected with the connector socket, and an output end of the ignition coil is connected with the spark plug. The overhead type ignition device is adopted so as to reduce energy loss caused by a high-tension cable.
Description
Technical field
The utility model relates to a kind of engine igniting coil, is specifically related to a kind of overhead type ignition mechanism.
Background technique
The core component of ignition mechanism is coil and switch gear, improves the energy of spark coil, and spark plug just can produce the spark of enough energy, and this is the primary condition that spark coil adapts to the Modern Engine operation.Along with the future development of automotive gasoline engine to high rotating speed, high compression ratio, high-power, low oil consumption and low emission, traditional ignition mechanism has been not suitable with usage requirement.The tradition ignition mechanism by spark coil, high voltage wire, the compositions such as spark plug.Traditional ignition mechanism is installed on motor side or the car body, then is connected in the cylinder by high voltage wire, because larger between engine air, the pressure drop on the high voltage wire is large, causes actual power character to reduce.
The model utility content
The technical problems to be solved in the utility model provides a kind of ignition mechanism that reduces the energy loss that high voltage wire causes.
In order to solve the problems of the technologies described above, the utility model provides a kind of overhead type ignition mechanism, include top and neck, described top is provided with spark coil, mounting hole and connector socket, described neck matches with mounting hole on the cylinder body, and its material is UP rubber, and its inside is provided with spark plug, the input end of described spark coil links to each other with connector socket, and output terminal directly links to each other with spark plug.
Adopt the overhead type ignition mechanism of technique scheme to have following advantage: because its neck directly is inserted in the engine cylinder-body, spark plug is arranged on neck, spark coil directly links to each other with connector socket and spark plug, saved traditional high voltage wire, avoided the pressure drop on the high voltage wire, thereby raised the efficiency; And UP rubber also has good high temperature resistant and insulation characterisitic, is conducive to the permanent use of overhead type ignition mechanism.
As preferred version, in order further to improve the tightness that ignition mechanism is combined with engine cylinder-body, described neck cross section is cylindrical, and its surface is provided with the axial projection that increases frictional force.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment overhead type ignition mechanism.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of overhead type ignition mechanism, include top 1 and neck 2, top 1 is provided with spark coil, mounting hole 11 and connector socket 12, and neck 2 matches with mounting hole on the cylinder body, its material is UP rubber, its inside is provided with spark plug, and the input end of spark coil links to each other with connector socket, and output terminal directly links to each other with spark plug, neck 2 cross sections are cylindrical, and its surface is provided with the axial projection 21 that increases frictional force
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
