点火

The survey principle of a magneto ignition system ignition advance angle was introduced.

本文介绍了磁电机点火系统的点火提前角测量原理。

Fluent software was used as a calculaˉ tion platform, and its UDF compiler was used to inject mass, mome ntum and energy of ignition gas and propellant gas into chamber. Combining with kˉε twoˉequation turbulence model and Pˉl radiation model, the 3ˉD nume rical simulation of ignition transient process of some solid rocket motor with st arˉshaped charge and a cove was conducted.

文中以Fluent软件为计算平台，采用UDF编译来实现点火燃气和推进剂燃气的质量、动量、能量向燃烧室的注入，结合 kε两方程湍流模型、 P l 辐射模型对某有堵盖的星形装药固体火箭发动机的点火瞬态过程进行三维数值计算。

In this paper, the effects of these random factors on the ignition delay of single particle and on the ignition delay of multipoint uniform ignition are investigated.

本文主要研究这些随机因素对火药颗粒点火过程的点火一致性和同时性的影响。

Research on the characteristics of RDX、 HNS、 PETN、 HMX and boron and carbon in them initiated by laser.

在RDX、HNS、PETN 和 HMX中搀杂硼和碳可以明显的提高药剂的激光吸收率，因而提高药剂的点火感度，缩短了点火延滞期。

Pilot burner system. LP gas or city gas, Pilot burner is ignited manually before each test

点火用气可选用液化石油气或者煤气，每次试验前需要手工点火。

Likewise, if the ignition switch is turned off, there can be no power event, but the ignition must occur before the power stroke can take place.

同样，如果点火开关关闭时，就没有权力的情况下，但必须在点火前的动力冲程才能进行。

In order to examine the south motorcycle engine preignition phenomenon, using the rich burning information of the massive ions which are produced when the air cylinder is burntThrough analyzing the wave form difference between lighting a fire normally and firing early, it can be determined whether preignition occurs or not.

为了检测南方摩托车发动机早燃现象，利用其气缸内燃烧时产生大量的离子电流信号所包含的丰富燃烧信息，对其火花塞正常点火和炽热点火离子电流显示的波形进行研究分析，从而确定是否发生早燃。

Meantime, through great deal of experiments, spark advance angles, ignition dwell angles, start injection width and electrical throttle threshold were optimally controlled. At last, quick response time of hydrogen-fueled engine was realized, speed stability after successful start was controlled. At the same time, backfire, preignition and fire a gun in the start state of hydrogen fueled engine were avoided.

同时通过大量试验调试，对点火提前角、点火闭合时间、喷气正时、电子节气门开度、起动喷气脉宽进行优化控制，使发动机起动响应时间快，起动后转速波动平稳；同时避免了氢燃料发动机起动时易出现的回火、早燃、放炮等异常燃烧现象。

In this paper, the relations of operating parameters such as coolant temperature, engine speed, throttle valve opening and spark advance angle with unburned hydrocarbon emissions due to the presence of combustion chamber deposits in spark ignition engine are investigated both theoretically and experimentally.

本文从实验和理论两个方面来系统地研究火花点火式发动机燃烧室沉积物处未燃碳氢排放浓度随冷却水温、发动机转速、节气门开度和点火提前角等运转参数的变化规律。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
