Abstract
The utility model relates to an overhead coil for a natural gas engine. The overhead coil for the natural gas engine comprises a copper bush and a protecting bush disposed in the copper bush, wherein one end of the copper bush is provided with a pressing bush, the pressing bush is fixedly disposed on a cylinder cover, an ignition coil is fixedly connected on the pressing bush, and the protecting bush is internally provided with a spring, with one end of the spring connected with the ignition coil and the other end connected with a sparking plug. The beneficial effects of the overhead coil for the natural gas engine are that engine performance is raised, replacement and examination frequency is lowered, safe reliability is improved, and maintenance costs are reduced.
Description
Technical field
The utility model relates to the natural gas engine technical field, relates in particular to a kind of natural gas engine overhead coil.
Background technique
Spark coil and the spark plug of natural gas engine generally are to connect by high voltage wire at present, and spark coil provides enough high-pressure energy, transmits high-voltage pulse by high voltage wire, the mixed gas so that plug ignition ignites in the motor, motor acting.
High voltage wire is because conformity difference, so that itself resistance difference is large, affect each cylinder igniting uniformity of natural gas engine, and high voltage wire produces easily the wearing and tearing electric leakage and shakes the shortcoming that causes bad connection, the in addition simple connection between spark coil, high voltage wire and the spark coil, its water proof and dust proof weak effect directly affects the performance of motor, need to check that the frequency of changing is higher, increased the maintaining cost.
The model utility content
The purpose of this utility model is to provide a kind of natural gas engine overhead coil, spark coil connects spark plug by high voltage wire in the prior art to solve, because high voltage wire self structure otherness causes plug ignition inhomogeneous, affects the technical problem of engine performance.
The utility model is to realize like this, a kind of natural gas engine overhead coil, comprise copper sheathing and be arranged at the interior sheath of described copper sheathing, one end of described copper sheathing is provided with gland, described gland is fixedly installed on the cylinder head, is fixedly connected with spark coil on the described gland, is provided with spring in the described sheath, one end tie point fire coil of described spring, the other end connects spark plug.
As improving further, the ceramic body terminal of described spark plug is arranged in the sheath and with an end of described spring and is connected.
After having adopted technique scheme, the beneficial effects of the utility model are: owing to utilize spring tie point fire coil and the spark plug that is provided with in the overhead coil, replace high voltage wire, solved because high voltage wire conformity difference, cause the resistance difference of high voltage wire own large, affect each cylinder igniting uniformity of natural gas engine, and produce easily wearing and tearing electric leakage, vibrations so that the shortcoming of high voltage wire, spark coil and spark plug bad connection and water proof and dust proof weak effect, thereby improved engine performance, reduced and changed the frequency that checks, reduced the maintaining cost.
Because the gland in the overhead coil is arranged on the cylinder head of motor, has so just fixed the position of overhead coil, guarantee overhead coil safety in use, reliability.
Because the ceramic body terminal of spark plug is arranged in the sheath in the overhead coil, and is connected with an end of spring, the tie point place is by the protection of sheath and copper sheathing, can prevent like this electric leakage and prevent dust, waterproof, Security is reliable during use.
Description of drawings
Accompanying drawing is the structural representation of the utility model natural gas engine overhead coil;
Among the figure: 1, spark coil, 2, gland, 3, sheath, 4, spring, 5, copper sheathing, 6, spark plug.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in drawings, a kind of natural gas engine overhead coil, comprise copper sheathing 5 and the sheath 3 that is arranged in the copper sheathing 5, an end of this copper sheathing 5 is provided with gland 2, an end tie point fire coil 1 of this gland 2, be provided with spring 4 in the above-mentioned sheath 3, one end tie point fire coil 1 of this spring 4, the other end connects spark plug 6, and above-mentioned gland 2 is fixed on the cylinder head of motor, the ceramic body terminal of above-mentioned spark plug 6 is arranged in the above-mentioned sheath 3, and is connected with an end of spring 4.
The utility model in use, utilize the overhead coil to connect electric fuse coil 1 and spark plug 6, specifically utilize the spring 4 that is provided with in the overhead coil, one end tie point fire coil 1 the other end connects spark plug 6, utilize the elastic force of spring 4 distortion to come guarantee point fire coil 1, the contact reliability of spring 4 and spark plug 6, spark coil 1 and gland 2 fixed seal connections, guarantee the cleaning of gland 2 and copper sheathing 5 inside, prevent entering of dust, impact contact sensitivity each other, the sheath 3 that copper sheathing 5 inside are provided with, prevented to a nearlyer step spark coil 1, the generation of electric leakage between spring 4 and the spark plug 6, whole coil is safe and reliable, changes to check that frequency is low, and maintenance cost is few.
A kind of natural gas engine overhead coil that the utility model provides, comprise copper sheathing and be arranged at the interior sheath of described copper sheathing, one end of described copper sheathing is provided with gland, be fixedly connected with spark coil on the described gland, be provided with spring in the described sheath, one end tie point fire coil of described spring, the other end connects spark plug.The use of overhead coil replaces high voltage wire, solved the conformity difference when using high voltage wire, it is inhomogeneous to cause lighting a fire, affect engine performance, and high voltage wire is because shaking the situations such as bad that easily come in contact, the use of this overhead coil has reduced changes the frequency that checks, safety reliability is high, has reduced maintenance cost.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
