Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: taking this as an example to further describe and illustrate the present application.

[0023] Such as Figure 2-5 As shown, this embodiment provides a plasma igniter with a gas outlet inclined hole and a multi-anode structure, including a plurality of short anodes located around, a long anode located in the center, a ground electrode, an anode insulating positioning sleeve, and an anode fastening nut and the anode insulation positioning sleeve pressing plate; the long anode has a hollow structure, is installed at the center of the igniter, and is fixed at the center of the anode insulation positioning sleeve; at the lower end of the long anode, there is a circumferentially arranged, inclined downward Several inclined air inlets are used to introduce a small amount of highly active particles formed in the ionization space b into the air...

Abstract

The invention discloses a plasma ignitor with an air outlet inclined hole and multi-anode structure. The plasma ignitor comprises a short anode, a long anode and an anode insulation positioning sleevewhich are located in a grounding electrode; an air inlet a inclined downwards is formed in one end of the upper portion of the grounding electrode, an air inlet b inclined downwards is formed in theother end of the upper portion of the grounding electrode, and the air inlet a, the air inlet b and an ionization space a are communicated; a plurality of air inlet inclined holes which are formed circumferentially and inclined downwards are formed in the lower end of the long anode. Due to the fact that fuel and air for ignition are introduced through the air inlet, no back flow of mixed gas inside a main combustion chamber is needed, the equivalent ratio of mixed gas in the ionization space a and the ionization space b can be controlled by adopting a method for controlling fuel flow throughthe air inlet b and air through the air inlet a according to the ignition condition, and the purpose of improving the ionization and ignition effect according to the actual working condition is achieved.

Description

technical field [0001] The invention relates to a plasma igniter, in particular to a plasma igniter with a gas outlet inclined hole and a multi-anode structure. Background technique [0002] As a clean energy, natural gas has been widely used as engine fuel. In the field of vehicle power, the number of passenger cars and heavy-duty vehicles fueled by CNG is increasing; in the field of ship power, CNG and LNG-powered ships have become the key research direction in the "Made in China 2025" plan. Compared with gasoline, natural gas as a gas fuel requires greater ignition energy, which makes it difficult to use a single spark plug to ignite natural gas even for small-bore vehicle natural gas engines in actual use, so gasoline has to be used to ignite the engine. normal work. This has led to a series of problems such as system complexity, cost increase, and reliability decrease. Therefore, it is necessary to adopt a new ignition technology and adopt a relatively simple structu...
