This text introduced that:(1) the technics way of the boring and reaming machine of motoreycle engine cylinder head's inlet and exhaust gateway pipe and seatcircle,(2) the advanced MAPAL cutting tool system structure,fixing and orientation characteristics,(3) the request of using this system ,and (4) the cutting parameter and machining effect.
本文介绍了摩托车发动机进排气门导管及座圈孔镗铰加工的工艺思路 ,着重介绍了MAPAL先进刀具系统的结构、安装定位特点 ,阐述了使用该系统对机床各部件的要求 ,对切削参数和加工效果作了较详细的叙
The effect of intake valve layout on intake process in gasoline engine;
进气门布置对汽油机进气过程的影响
Used bench test, it simulated load environment and contact condition of diesel engine intake valve and seat,researched the wear mechanism and analyzed the influence factor.
通过台式试验装置模拟柴油机进气门与座圈的负荷环境和接触条件,研究了进气门与座圈的磨损机理,分析了进气门与座圈磨损的主要影响因素。
"That is to say, each cylinder has two valves, an intake valve and exhaust valve."
也就是说,每个气缸有两个气门,即进气门和排气门。
This action could open an inlet valve for an intake stroke, or open an exhaust valve for an exhaust stroke.
这过程能使进气门在进气行程打开，或者排气门在排气行程打开。
"On the intake stroke, the intake valve has opened, the piston is moving downward, and a mixture of air and vaporized gasoline is entering the cylinder through the valve port."
"在进气行程中,进气门打开,活塞向下移动,可燃混合气通过进气门进入气缸。"
"Valve deposits. If the fuel has excessive amounts of gum in it, some of this gum may be deposited on the intake valve as the air-fuel mixture passes the valve on the way to the engine cylinder."
气门积垢:如果燃油中含有过量的胶粘剂,当混合油气通过气门进入气缸时,就会沉积在进气门上。
Carbon deposits may form because of an excessively rich mixture or because of oil passing a worn valve guide (in the intake valve).
混合气过浓或润滑油流到磨损的气门导管中(进气门),都可形成积炭。
