喷射口

The purpose of the invetion is to effectively stop the blowoff of an injected fuel into an exhaust port when the opening and closing of valves are overlapped with each other by properly setting the fuel injection direction of a fuel injection device mounted so as to face the intake passage of an internal combustion engine.

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

计算结果表明：采用本文的计算方法可以模拟出火花型激励器喷射、吸入的工作阶段；电火花瞬间能量的输入产生了腔体内的高温、高压环境，从而诱发合成射流的形成；当激励能量增加，激励器产生的合成射流速度增加，可达到超声速状态；周期性激励下，火花型合成喷喷口处的轴向平均速度随时间不是正弦分布，且喷射过程的最大速度要远远大于吸收过程的最大速度。

In order to increase the efficiency, pumps were improved, eject pump had two inlets, each was located on one side of pump, and the inlet of centrifugal pump was used as one Enteromorpha prolifera inlet.

为了进一步提高装置的工作效率，在原有设备的基础上，对离心泵和喷射泵均进行改进，喷射泵改为双吸口，位于泵体两侧，同时离心泵的入水口也作为浒苔吸口使用，并给出喷射泵主要设计参数。

These results clearly justifies that in combustor, the injector location and its conditions have no effect on the flowfield structure but have strong effect on the combustion efficiency, and that inside the engine, undesirable injector conditions can result in the engine thermal choked and unstart.

第五章计算了含横向喷流的二维燃烧室和一种简化一体化超燃冲压发动机流场，发现在燃烧室中喷口位置及喷射条件对流场的结构影响不大，但对燃烧效率却有较大的影响；而在发动机内部，不适当的喷射条件，有可能引起发动机的&热壅塞&，使发动机无法启动。

In the gas technique, two gas burners are placed so that both the front and back of the cloth is singed in a single pass through the equipment. The hot cloth is then passed through water or steam to extinguish any sparks that may be present.
