Embodiment Construction

[0018] Such as figure 1 As shown, an engine ignition device of the present invention is characterized in that it includes: a cylinder, a spark plug, a piston, a cylinder head, etc., and is characterized in that the cylinder head has a needle electrode.

[0019] The piston 2 is in the cylinder 1, and the piston 2 has a needle electrode, and the cylinder head 3 has a needle electrode 4 correspondingly on the cylinder head. The electrode corresponds to the position of the electrode 5 on the piston, and the distance is the smallest when the piston moves to the top dead center. The number of needle electrodes on the cylinder head and the electrode needles on the piston can be inconsistent. It is also possible to have acicular electrodes on one side and a common metal surface on the other side.

[0020] Beneficial effect

[0021] The invention will improve the combustion efficiency of the internal combustion engine and reduce the pollutant emissions.

Abstract

The invention provides an ignition device for an engine. The device adopts a piston and a cylinder cover which are provided with needle electrodes at the same time, wherein two kinds of electrodes are correspondingly arranged, and ignition is carried out when the distance is shortest, and long arc duration ignition is maintained by utilizing high voltage arc ionized air in a process that the piston moves far away from the cylinder cover to ensure that combustible gas can be sufficiently burnt and achieve the effect of comprehensively improving the efficiency and emission of the engine. To ensure stable arc, the electrodes adopt a multi-needle structure.

Description

technical field [0001] The invention relates to an engine ignition device. Background technique [0002] Piston internal combustion engines are divided into two categories according to their compression ratio and ignition method, one is an internal combustion engine with electric spark ignition, and the other is an internal combustion engine with high pressure self-ignition. At present, gasoline, ethanol, natural gas, etc. are widely used as fuels for spark ignition internal combustion engines. Today, with the development of this kind of internal combustion engine technology is becoming more and more mature, we can still find that this type of engine has the following disadvantages: one is the phenomenon of black smoke, the other is the problem of reduced efficiency under low or high speed conditions; the third is the problem of unstable operation. These problems are mainly reflected in the decline of engine efficiency, and the emission of carbon monoxide, unburned smoke an...
