A method and apparatus for increasing the propelling force of pulse engine features that the fuel nozzle of pulse explosion engine is arranged in combustion chamber to close jet tube exit, and the fuel is reversely sprayed out to generate a shock wave barrier near the jet tube for preventing the airflow from flowing out of the combustion chamber, resulting in raising the pressure in combustion chamber and in turn increasing the propelling force.

本发明公开了一种提高脉冲发动机推力的方法和装置，它是通过将脉冲爆轰发动机的燃料嘴置放在燃烧室中靠近喷管出口附近，并使燃料逆向喷出，在燃烧室内靠近喷管附近形成一道阻止气流流出燃烧室的激波，激波的作用是使燃烧室压力升高，从而的到较大的推力。同时由于本发明的结构特别的简单，所以实现非常容易，并且工作效果十分显著。

A control apparatus for an engine increases an intake air quantity just before engine stop to increase a compression pressure in a compression stroke.

一种发动机(11)的控制装置(30)，用于在发动机停止之前增加进气量从而增加了压缩冲程中的压缩气压。

As the compression pressure is increased, a negative torque in the compression stroke increases and obstructs engine rotation, and brakes the engine rotation.

随着压缩气压增加，压缩冲程中的负转矩也增加并阻碍发动机旋转，从而停止发动机旋转。

Because a smaller portion of the compression stroke is devoted to compressing the intake air, an Atkinson-cycle engine does not take in as much air as would a similarly designed and sized Otto-cycle engine.

因为在压缩冲程小部分是用于压缩进气，一阿特金森循环发动机不参加尽可能多的空气那样，是同样大小的设计和奥托循环发动机。

By adjusting the linkage to allow a power stroke that is longer than the compression stroke, the engine can achieve greater efficiency than with the Otto cycle engine.

通过调整挂钩，使权力中风，比压缩冲程长，发动机可以达到，但与奥托循环发动机的效率。

The highly efficient Atkinson-cycle engine, made possible by the Variable Valve Timing with intelligence system, allows the expansion/power stroke to be longer than the compression stroke so that combustion energy can be more effectively used for production of engine power.

高效的阿特金森循环发动机，作出与智能可变气门正时系统，可以使扩充/动力冲程要长于压缩冲程，使燃烧的能源可以更有效地用于生产发动机力量。

Through the analysis of different cross section flow field in cylinder of two-valve and four-valve diesel engine, the following conclusion can be obtained: The formation of intake swirl of two-valve diesel engine mainly is effected by an intense air flow ring zone near the radius from valve axis to cylinder axis, as the flow progresses down through the cylinder, the ring zone air flow expends to both side and finally forms an unified rigid rotating swirl motion.

2号缸盖的螺旋进气道产生的绕自身气门轴线的动量矩比1号缸盖的大，且切向气道的径向速度在前峰面上的数值比1号缸盖的速度数值大很多，因此，两进气道组合后的动量矩损失也大，所以虽然2号缸盖的两个进气道单独的涡流比都高于1号缸盖的两个进气道，但组合后的合成涡流比却是基本相同的。

According to work piece size, characteristic and its material choice cutting specifications; Because of the thick mill diesel engine cylinder body two sides, then the jig design use "two sells the localization at the same time", Manual clamps, an attire clamps processes the diesel engine to be mad the cylinder body two sides; according to will work receives the cutting force to calculate clamps the strength; again according to clamps the strength , choose the determination clamp the special-purpose part.

由于是粗铣柴油机气缸体两侧面，则夹具的设计采用&一面两销&定位，手动夹紧，一次装夹加工柴油机气缸体的两个侧面，保证了加工精度，提高了生产效率；根据工作将受到切削力来计算夹紧力；再根据夹紧力来选择确定夹紧装置的专用部件。

At present, the advance of the diesel engine to more power and lighter weight decreases its stiffness and enhance the vibration of the components, directly affecting the working cycle of the diesel engine.

目前，柴油机正向着大功率、轻重量的方向发展，其刚度不断减小，加剧了部件的振动，直接影响了柴油机的寿命。

Objective:To compare the response control and attention of Schizophrenic patients with that of the healthy controls by Integrated Visual and Auditorycontinuous performance test. To quantitate the impairment of cognitive function in patients, and to explore the relationship between cognitive function and the severity of the disorder.

目的：探讨精神分裂症病人在IVA持续操作测试中的反应控制能力、注意力等，并与健康人进行比较，从而量化精神分裂症病人的认知功能损害，并进一步探讨其认知功能与疾病严重程度的关系。

Main effective factors including subcooling degree, mechanical vibration, gas hydrate reformation, environment temperature, noncondensing gas and surfactant are analyzed.

指出过冷度、机械振动、重复生成水合物、环境温度、不凝性气体、添加剂是影响气体水合物生成的主要因素，还对R152a水合物的放冷进行了实验研究。
