Valve Timing

The time at which valves open and close ( valve timing ) and the duration of the valve opening in stated in degrees of crankshaf(转 载 于:wWw.HnnsCY.cOM 博文学习网:at英语翻译)t rotation . 气门打开和关闭的时间（配气正时）和气门打开持续的时间在曲轴旋转的角度。

For example , the intake valve normally begins to open just before the piston has reached the top dead center .比如，进气门通常只在活塞到达上止点的时候开始打开。

The valve remains open as the piston travels down to BDC and even past BDC . 进气门在活塞下行到下止点甚至超过下止点过程中继续打开。

This is intake valve duration .这是进气段。

An example of this could be stated as follows :这方面的一个例子可以说明如下： IO at 17BTDC , IC at 51ABDC ( or , intake opens 17before top dead center , intake closes 51after bottom dead center ) . Intake valve duration in this case is 248 of crankshaft rotation . IO at 17BTDC , IC at 51ABDC（也就是说，进气在上止点前17度打开，在到达下止点51度以后关闭）。在这个事例中进气过程曲轴转了248度。

This leaves 129 duration for the compression stroke since compression ends when the piston reaches TDC .在129度离开开始压缩冲程，压缩在活塞到达上止点的时候结束。

At this point the power stroke begins .此时，做功冲程开始。

The power stroke ends when the exhaust valve begins to open approximately at 51 before bottom dead center .大概在排气门打开前51度时做功冲程结束。

The duration of the power stroke in this case is also 129 .在这个事例中做功冲程所转的角度也是129度。

Since the exhaust valve is opening at 51 BBDC , this begins the exhaust stroke .从排气门打开到51BBDC以后，排气冲程开始。

The exhaust stroke continues as the piston passes BDC and moves upward to past TDC .排气冲程随着活塞经过下止点并上行至上止点。

With the exhaust valve closing at 17 TTDC , the duration of the exhaust stroke is 248 .随着排气门在17TTDC关闭，排气冲程所转的角度是248度。、

It is apparent from this description that the exhaust valve stays open for a short period of time during which the intake valve is also open .从以上描述中，显而易见，排气门在进气门也打开时仍然保持开启状态一小段时间。

In other words , the end of the exhaust stroke and the beginning of the intake stroke overlap for a short period of time .换言之，排气冲程的结束和进气冲程的开始有一小段时间的重叠。

This is called valve overlap . Valve timing and valve overlap vary on different engines.这个称为气门重叠。配气正时和气门重叠变通用于不同的发动机。

Opening the intake valve before TDC and closing it after BDC increase the fill of air-fuel mixture in the cylinder .在上止点前打开进气门并在下止点增大气缸内的油气混合物之后关闭。

Opening the intake valve early helps overcome the static inertia of the air-fuel mixture at the beginning of the intake stroke , while leaving the intake valve open after BDC takes advantage of the kentia of the moving air-fuel mixture . This increase volumetric efficiency .早一些开启进气门有助于克服在进气冲程开始的油气混合物的静止的惯性，当离开时利用先前的移动的油气混合物让进气门在下止点之后打开。

As the piston moves down on the power stroke past the 90 ATDC position , pressure in the cylinder has dropped , and the leverage to the crankshaft has decreased due to connecting rod angle and crankshaft position .当活塞下行在做功冲程超过90ATDC的位置时，缸压已经降低，并且曲轴的杠杆作用由于连杆角度和曲轴位置已经减少。

This ends the effective length of the power stroke , and the exhaust valve can now be opened to begin expelling the burned gases .这个终止做功冲程的有效长度，并且排气门此时被打开开始排出燃烧的气体。 The exhaust valve remains open until the piston has moved up past the TDC position .排气门直到活塞上行到上止点的位置依然处于打开状态。 This helps to remove as much of the burned gases as is possible and increase volumetric efficiency .这有助于尽可能清除足够多的燃烧的气体并增加充气系数。

2.4.4 Cam Design and Control Dynamics 凸轮设计和控制动力学

The function of the cam is to open and close the valves as far as possible , as fast as possible and as smoothly as possible . 凸轮的功能是尽可能长地、尽可能快地以及尽可能平顺地打开和关闭气门。The closing force for the valves is applied by the valve spring which also maintain contact between the cam and the valves . Dynamic

force impose limits on cam and valve lift .The closing迫使气门被维持凸轮和气门连接的气门弹簧顶开

The entire valve-train assembly can be view as a spring \mass system in which the conversion from stored to free energy causes force vibration .整个气门传动组件可看做是一个弹簧/质量系统，在这个系统中，能量储存与释放的转换引起振动。 Valve-train assemblies with overhead camshafts can be represented with sufficient accuracy by a 1-mass system ( consisting of the moving mass , the valve-train assembly stiffness and corresponding damping ) .带有顶置凸 轮轴的气门机构可非常精确地用单质量系统来表示，（ 由运动质量、气门机构的刚度和相应的阻尼组成。）

For system with valve bottom-mounted camshaft and push rods , a 2-mass system is being increasingly used .

The maximum permissible contact stress , usually regarded as the parameter which limits cam-lobe radius and the rate of opening on the flank , currently lies between 600-700Mpa depending upon the material parings used .

2.4.6 Electronic Valve Control System

An electronic value control (EVC) system replaces the mechanical camshaft, controlling each value with actuators for independent value timing. The EVC system controls the opening and closing time and lift amount of each intake and exhaust valve with independent actuators on each value. Changing from a mechanical camshaft driven value into independently controlled actuator valves provides a huge amount of flexibility in engine control strategy. 电控气门系统代替机械式的凸轮轴，用执行器控制每个气 门独立的进、排气正时。EVC通过每个气门上的独立执行器 控制进气门和排气门的开启、关闭时间以及升程量。由机 械式驱动气门到独立控制执行器的气门改变，极大的增加 了发动机控制策略的灵活性。 Vehicles utilizing EVC can realize several benefits including:汽车利用电控系统可以实现一些便利包括：

1)increases engine power and fuel economy,提升发动机动力和燃油经济性

2)allows centralized and distributed EVC systems to perform at their full potential,允许集中和分散的电控系统在充足的可能性下工作

3)adapts to engines of varied cylinder counts.适应各种不同气缸的发动机

With all of the improved efficiencies and consumer benefits, auto manufacturers are eager to get their first EVC systems on the road. The EVC system is targeted to operate in temperatures up to 125, while the actuator is targeted to run up to 6000 r/min. The actuator can be controlled in a centralized system with a high-speed multiplex bus (up to 10Mbps) or in a distributed system with a nominal speed bus.
