Abstract
The utility model relates to a kind of engine laser ignition device.The utility model forms and comprises: the laser that vehicle power excites (1), described laser is connected with optical fiber (2), described laser and described optical fiber be arranged on window (3) directly over, described window embeds in the cylinder wall of cylinder (6) top or sidepiece by jig (4), in the middle of described jig, having seal ring (5), described window is the convex lens that adopt Nd:YAG pottery.The utility model is for engine ignitor.
Description
technical field:
the utility model relates to a kind of engine laser ignition device.
background technique:
laser ignition is used laser energy ignite or ignite energetic material.Laser ignition is widely used in space flight and military aspect at present, and technology comparative maturity.The specific power of Modern Laser application has reached 10

above.Laser ignition mode has: single-point igniting, two point igniting and multi-point spark.Laser Ignition System is comprised of four parts such as laser, optical fiber and fibre-optical splice, laser ignition element and safty device.
model utility content:
the purpose of this utility model is to provide a kind of engine laser ignition device.
the purpose of this utility model is achieved in that
a kind of engine laser ignition device, its composition comprises: the laser that vehicle power excites, described laser is connected with optical fiber, described laser and described optical fiber be arranged on window directly over, described window embeds by jig in the cylinder wall of cylinder head or sidepiece, has seal ring in the middle of described jig.
described window is the convex lens that adopt Nd:YAG pottery.
beneficial effect:
1. use laser ignition can increase lean-burn boundary; Multi-point spark can be realized, the flame mechanism of weak mixture can be accelerated; Ignition location can leave combustor surface, the heat transfer loss while having reduced igniting; Effectively control firing time and ignition intensity, and easily realize automatically controlled; Without electrode, there is not electrode erosion problem;
2. during because of engine operation, the temperature in cylinder is very high, and has concussion, so window must be high temperature resistant, shock-resistant.YAG crystalline ceramics, it is corrosion-resistant, wear-resistant that it has high temperature resistant (1950 ℃), shock-resistant, hardness high (Mohs hardness 8.5), intensity is high, the features such as refractive index (1.83) is low, and the light penetration in 0.23～8.0 mu m waveband still can reach 84%, and linear expansion coeffcient is little.At visible ray infrared band, there is good through performance, can be used for transparent armor, the watch window of material of infrared window, high-temperature high-pressure apparatus.The fusing point of Nd:YAG pottery, 1950 ℃ of left and right, can bear the high temperature in cylinder, adopts Nd:YAG pottery as the material of window, makes a difficult problem that has broken through prior art after lens.The utility model adopts crystalline ceramics lens (1) to have the physicochemical properties similar to monocrystalline, spectral characteristic and laser activity; (2) easily prepare large-sized laser transparent ceramic, and shape is easily controlled; (3) manufacturing cycle is short, and cost of production is low; (4) can realize high-concentration dopant, optical uniformity is good; (5) can prepare multilayer and multi-functional laser-light transparent lens.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of engine laser ignition device, its composition comprises: laser 1, described laser is connected with optical fiber 2, described laser and described optical fiber be arranged on window 3 directly over, the laser 7 that laser sends is by fiber-optic illuminated on window, described window embeds in the cylinder wall of cylinder 6 tops or sidepiece by jig 4, has seal ring 5 in the middle of described jig.
embodiment 2:
according to the engine laser ignition device described in embodiment 1, described window is the convex lens that adopt Nd:YAG pottery, has focusing function and higher fusing point and higher transmittance.
embodiment 3:
according to the engine laser ignition device described in embodiment 1, described laser power is high, good stability, and volume is little, generally adopts impulse semiconductor laser; The single pulse energy of described laser is higher than the combustion threshold of gasoline; Described laser can be excited by vehicle power.
