{*>[1] The present invention relates to an ignition device, and more particularly, to an ignition plug for an internal combustion engine which is capable of enhancing the combustion performance of the combustion engine and reducing a generation of nitrogen oxides (NOx), while being used for a prolonged period of time.<}999{>本发明涉及一种点火装置,且更详细地讲,涉及一种用于内燃发动机的火花塞,当长期使用时,该火花塞能够增强内燃机的燃烧性能并降低氮氧化物(NOx)的生成。<*}
{*>Background Art<}999{>背景技术<*}
{*>[2] Internal combustion engines, which are mainly used as vehicle engines, may be classified into a 4-cycle engine and a 2-cycle engine. <}999{>主要用作车用发动机的内燃发动机可划分为4循环发动机和2循环发动机。<*}{*>The 4-cycle engine has a compression stroke, a suction stroke, a combustion stroke, and an exhaust stroke.<}999{>4循环发动机具有压缩冲程、吸入冲程、燃烧冲程和排气冲程。<*}
{*>[3] Such an internal engine uses an ignition plug, in order to burn a gas mixture in a combustion stroke. <}999{>该种内置发动机采用火花塞以便在燃烧冲程中燃烧混合气体。<*}{*>That is, the ignition plug means a spark discharge device for igniting a gas mixture compressed in an internal engine.<}999{>也就是说,火花塞意思指用于点燃内置发动机中受压混合气体的火花放电装置。<*}
{*>[4] Generally, where such an ignition plug is used in spark ignition type internal combustion engine using high-octane gasoline, the ignition timing point of the ignition plug should be determined depending on the rotating speed of the internal combustion engine, in order to obtain a combustion efficiency for an appropriate output power required in the high-performance internal combustion engine.
<}999{>通常,当该种火花塞用于使用高辛烷值汽油的火花点火型内燃发动机时,火花塞的点火正时点应根据内燃发动机的转速而确定,以便在高性能的内燃发动机中获得为适当的输出功率所需的燃烧效率。<*}
{*>[5] For example, when the rotating speed of the internal combustion engine is low, ignition is carried out at the point of time corresponding to a crankshaft angle of about -6° from a top dead center (TDC), namely, a position earlier than the TDC by an angle of about 6° As the rotating speed of the internal combustion engine increases, the ignition timing point is further earlier than the TDC That is, when the rotating speed of the internal combustion engine increases, an advanced ignition is carried out to obtain a maximum engine output power. <}999{>例如,当内燃发动机的转速低时,在对应于曲柄角自上止点(TDC)开始大约为-6°的时刻进行点火,即先于TDC大约6°角的位置。随着内燃发动机转速的增加,点火正时点进一步先于TDC。也就是说,当内燃发动机的转速增加时,为获得最大的发动机输出功率而进行提前点火。<*}{*>Although the point of time when the advanced ignition is generated depends on the rotating speed of the internal combustion engine, the advanced ignition is typically generated at an angle of about - 50° from the TDC<}999{>尽管产生提前点火的时刻取决于内燃发动机的转速,但提前点火通常发生在从TDC开始大约成-50°的角度处。<*}
这是前端时间作的一个测试稿,被鄙视了。估计人家那边比较严或是有其它什么目的,鄙视就鄙视了,当我觉得翻译得还行。。。 |
