Abstract

The invention discloses a plasma igniter with hollow ventilation anodes. The plasma igniter with hollow ventilation anodes comprises an upper anode, a low anode and an anode insulating sleeve which are arranged inside a grounding electrode, wherein the anode insulating sleeve is arranged at the upper portion of the grounding electrode, the upper anode is embedded inside the wall of the anode insulating sleeve, and one end of the lower anode extends into the mounting hole of the anode insulating sleeve; the anode insulating sleeve is composed of a groove a, a groove b and a groove c which are sequentially connected from top to bottom and communicated with one another; the lower anode comprises a boss a, a boss b, a boss c and a platform which are connected with one another, the boss a is arranged inside the groove a, the boss b is arranged inside the groove b, the boss c is arranged inside the groove c, and the platform is arranged at the lower portion of the grounding electrode. The plasma igniter with hollow ventilation anodes can achieve the aim of high-energy and stable ignition within a broad fuel-air ratio range.

Description

technical field [0001] The invention relates to a plasma igniter, in particular to a plasma igniter with a hollow ventilated anode. 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 directions in the "Made in China 2025" plan. Compared with gasoline, natural gas as a gas fuel requires more ignition energy, which makes it difficult to use a single spark plug to ignite natural gas even with a small-bore vehicle natural gas engine in actual use, so other fuels have to be used to ignite or set a preset. The way the combustion chamber makes the engine work properly. This leads to a series of problems such as system complexity, increased cost, and decreased reliability. Therefore, it is necessary to adopt a new ignition technology and a r...
