The possiblehost objective reason all is very many, but, our country numericalcontrol engine bed function part development backwardness -- varietyfew, unit technical level low, performance quality insufficientlystable, the cost stays at a high level, the delivery insufficientlywas prompt and so on -- not to be able to satisfy the numericalcontrol engine bed main engine product need to develop, had noalternative but to say was most direct, the most main reason, Becauseall numerical controls engine bed all is by each kind of function part(including host 轴头, straight line rolls guide rail, ball bearingguide screw vice-, numerical control tool rest, knife storehousemanipulator, rotary table, numerical control servosystem, surveyfeedback as well as safe protective equipment and so on), the functionpart which on foundation rack and so on the lathe bed, column thecollection attire becomes is the numerical control engine bedimportant component, moreover is the indispensable part.

可能主客观原因都是很多的，但是，我国数控机床功能部件的发展落后──品种少，单元技术水平低，性能质量不够稳定，成本居高不下，交货不够及时等──满足不了数控机床主机产品发展的需要，不能不说是最直接、最主要的原因，因为所有的数控机床都是由各种功能部件（包括主轴头、直线滚动导轨、滚珠丝杠副、数控刀架、刀库机械手、回转工作台、数控伺服系统、测量反馈以及安全防护装置等）在床身、立柱等基础机架上集装而成的，功能部件是数控机床的重要组成部份，而且是不可或缺的部份。

By utilizing electromagnetic valve, we can control opening and closing timings of intake and exhaust valves according to the operating situation of the engine. Therefore, the engine performance can be improved suitably in exhaut emission during starting, idle stability, fuel comsumption and engine power, etc. When an engine rotates in the low speed, gas flow is bad and the throttle which adjusts air mass is apt to cause the pumping lose of the engine.

中文摘要传统机械式可变汽门正时系统为分段固定式机构，无法根据引擎转速以及负载变化来提供适当的汽门正时；利用电磁式气阀可根据引擎当时状况控制进排气门的开启与关闭正时以及汽门持续开启正时，因此引擎在冷启动废气排放、怠速稳定性、燃油消耗率以及引擎性能等方面均相当之改善。

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。
