Problems solved by technology
The general booster is easily broken down by high voltage due to its small size, so its energy is limited
Not only that, even if it is difficult to make a booster with this kind of energy, high-voltage wires must be used to connect it when making it. In this way, the energy loss will be greater, and it will be more difficult to ignite the high-calorific-value natural gas fuel of the engine.

Embodiment Construction
[0024] See attached figure 1 , this embodiment of the overhead booster for natural gas engine ignition of the present invention is made of PVC plastics and made into a rectangular plastic shell 2 with a thickness of 1mm, and the size is 64 × 92mm 2 . A commercially available epitaxial iron core 5 is arranged inside the casing 2 . One end of the extension iron core 5 protrudes from the casing 2 and is fixedly assembled on the casing 2 . The epoxy resin 11 is filled between the epitaxial iron core 5 and the shell 2 under the condition of a vacuum within 200 Pa to seal the low-voltage coil 4 and the high-voltage coil 3 . The high-pressure rod 8 is cylindrical, with a length of 180mm and a cylinder diameter of Φ22mm. The high-pressure rod 8 is fixedly connected to the housing 2 coaxially. The size of the spring 9 matches the size of the inner cavity of the high pressure rod 8 and the coaxial device is clamped on the high pressure copper head 7 in the inner cavity of the high p...

The invention discloses an overhead booster for ignition of a natural gas engine. High-voltage coils (3) and low-voltage coils (4) are wound on an epitaxial iron core (5) of the booster; the low-voltage coils (4) have a small number of turns, a large section diameter of enameled wires and a low-voltage socket (1); and the high-voltage coils (3) are connected with one end, facing inwards, of a spring (9) in a high-voltage rod (8) by a high-voltage connecting sheet (6). The booster is simple in structure, convenient to install and particularly applicable to environment-friendly natural gas automobiles. The overhead booster for the ignition of the natural gas engine, after tested, has the advantages that: 1, the booster is difficult to puncture, and the output energy and voltage of the booster can be improved; 2, a high-voltage line is not required, a space is saved, and loss is reduced; 3, requirements on the quality of raw materials are not high; 4, the booster is applicable to single-cylinder configuration and computer control, and the ignition is more accurate and more reliable; and 5, the epitaxial iron core (5) is difficult to crack, reliability is improved, and the service life of the booster is prolonged.
Description
technical field [0001] The invention belongs to the technical field of engine ignition devices, and relates to an ignition device for a natural gas engine that can raise a low pressure to a high pressure, in particular to an overhead booster for natural gas engine ignition. Background technique [0002] Since the natural gas engine uses natural gas with a high calorific value as fuel, its ignition device, that is, the spark plug, has a high requirement for the ignition pressure of the booster. A general booster is easily broken down by high voltage due to its small size and other reasons, so its energy is limited. Not only that, even a booster with such energy is difficult to make large, it must be connected with high-voltage wires during production, which will cause greater energy loss and make it more difficult to ignite the high-calorific-value natural gas fuel of the engine. Contents of the invention [0003] The technical problem to be solved by the present invention...
