On the left picture you see the WAK rear intake engine on the model. 在左边的图片你看到wak后方进气引擎的模型。
Yes we will use it this year !! 是我们将用它在今年！
On the right picture you see Monique, my sister, showing a typical Wakkerman model but hiding the engine !! 在右边的图片你看到莫妮克，我的姐姐，显示一个典型的wakkerman模式，但隐瞒引擎！
This engine will also be used against YOU. 这个发动机也将被用来对付你。

Two different engines for FAI combat. 两个不同的引擎辉作战。 This should make you very nervous. 这应该让你很紧张。 On the right we see the new version of the twin exhausted WAK engine. 在右边，我们看到了新版本的双用尽wak引擎。 This is a front intake and is a further development of the older LMT engine and the younger WAK rear intake engine. 这是一个前线摄入量，是一个进一步发展的旧lmt引擎和年轻wak后方进气引擎。
On the left you see the L+L engine which is designed by Lothar Hentschel (Germany) and myself 在左边您会看到升+升发动机是设计的洛塔尔hentschel （德国）和我本人
Both engines show some very clearly side ports. 两个引擎出现一些很清楚，方港口。 Not like in standard engines where the ports are normally 2 mm deep. 不喜欢在标准的引擎所在港口通常是2毫米深。 Shiver and read the story of these engines. 寒战和阅读的故事，这些引擎。

Both engines show some clear differences from 'normal/standard' engines. 两个引擎出现一些明显的差别，从正常/标准』的引擎。
First, the side porting is different. 首先，一侧移植是不同的。 At the lowest point the port is approx. 在最低点，港口，是约。 3.4 mm deep and 5.5 mm. 3.4毫米深和5.5毫米。 wide. 宽的。 At the highest point it is only 1.7 mm. 在最高点，这是只有1.7毫米。 deep and as wide as the port in the cylinder. 深和广泛的港口在气缸。 The square surface area decreases by 10 % so assuring an acceleration of the gasses. 广场面积下降了10 ％ ，因此，保证一个加速度的气体。
Second, as you might have seen the exhaust is positioned under an angle of 30 degrees downwards . 第二，正如你可能已经看到废气是定位下一个角度30度， 向下 。 The advantage is that a flooded engine will be easier to start as when the exhaust is positioned upwards. 的优势，这是一个充斥引擎将可以更轻松地开始时，排气的位置向上。 No difficult starting procedures for inexperienced pitman. 没有困难的开始，程序，经验不足的皮特曼。

As already mentioned the engine above (right) is a further development of the WAK rear intake engine developed in 1996. The idea behind the deep side ports is following : take one of your engines and take the cylinder and piston out. 正如已经提到的发动机以上（右）是一个进一步发展的wak后方引擎开发的摄入量在1996年。 背后的想法深方港口是以下内容 ：以您的其中一个引擎，并采取汽缸和活塞。 Take a good look inside at the side ports. 采取一个良好的内，看看在一侧的港口。 They are nicely formed. 他们是很好的形成。 Put the backplate in. 把backplate英寸
Conclusion : the backplate closes a part of the side ports so the effectiveness of these ports will be less. 结论 ： backplate 关闭 的一部分，一侧的港口，使这些措施的成效港口将会减少。
Both new engines are supplied with integral cylinders. 这两个新的引擎供应积分气瓶。 The piston is made with a coned head (see picture in the middle). 活塞是与锥D头（见图片中的中） 。
The cylinders and pist** for these engines are made by: 汽缸和活塞这些引擎都发了言：

WAK rear intake engine. wak后方进气引擎。
No dirty engine after a ground hit!! 没有肮脏的引擎后，地面击中！
Models more difficult to build. 模型更难以建立。
Both crankcases are established by the lost WAX method which means that you have to make a negative mould. 双方曲轴箱，建立了由失蜡法这意味着你必须作出负面的模具。 In this case 2 of them. 在这种情况下2人。 Once you have made these forms the WAX is pressed in with approx. 一旦你取得了这些形式的蜡是压在与约。 40 bar at a temperature of about 65 degrees Celsius (do you Americans know what a Celsius is ?). 40酒吧在温度约65摄氏度（你美国人知道什么是摄氏是什么？ ） 。

On the 3 pictures around this text you can see some of the procedure when making the wax crankcases. 对3图片变通解决此文字，您就可以看到一些程序时，使蜡曲轴箱。 On the left picture (above) you see that the form is still closed and the so-called venturi-adapter is pulled out. 在左边的图片（以上） ，你看到的形式，仍是封闭和所谓的文丘里-适配器是退出。 At the right picture Lothar Hentschel is trying to open/split the negative mould. 在适当的图片洛塔尔hentschel是尝试打开/分裂的负面模具。 And the next picture shows a wax crankcase and some parts of the negative mould. 和下一张图片显示了蜡曲轴箱和部分负面模具。
These Wax crankcases were brought to an Aluminiumcaster. 这些蜡曲轴箱被带到一aluminiumcaster 。 There they 'glue' the wax crankcases to a so-called wax 'tree'. 有他们的'胶水'蜡曲轴箱，以一个所谓的蜡'树' 。 The wax tree with crankcases is put into a vessel with a slurry of special gypsum. 蜡树与曲轴箱是把一艘船与水泥浆特别石膏。 After the gypsum is hardened the total is heated up till approx. 后石膏是硬化的总加热直至约。 1200°C. 1200 ° C时 The wax disappears totally without leaving rest parts like ash. 蜡消失，完全没有留下，其余的部分，像灰。 Then the aluminium A357 can be poured in. In the end the crankcases receive a T6 heat treatment to give it a certain stiffens/hardness and good manufacturing abilities. 那么，铝a357可以浇英寸，在结束曲轴箱收到T6的热处理给它一个某些stiffens /硬度和良好的制造能力。
