Vehicle maintenance experts believe that the current engine is increasingly pursuing power function, even pulling out the three-cylinder engine, plus a turbine to enhance power function, completely ignoring the stability. Of course, there are no inconsistent oscillations in the category of luxury cars. Recently, the V6 engine has become a synonym for fluency. Even many partners believe that the use of the V6 engine must be very smooth. Nevertheless, the latest generation of S-class engines have chosen straight-tube six-cylinder engines from the very beginning to re-ignite the feeling of straight-tube six-cylinder engines. After all, what's the magical power of a straight six-cylinder engine? Why can luxury brands not forget it?

　　汽車保養四缸發動機比六缸發動機更狗屁

　　Car Maintenance Four-Cylinder Engines Are Worse than Six-Cylinder Engines

　　隨著排放和燃油經濟性的要求，小排量四缸發動機已經成為流行，甚至d級豪華車也有2.0 t發動機。汽車保養表示,其新的四缸引擎可以與光滑的六缸發動機相比,但很少有人敢拿出四缸發動機,直列六缸發動機一起競爭光滑,現在越來越流行的直接注入汽缸技能嚴重爆炸襲擊,使發動機振動和噪聲更重要。

　　With the requirement of emission and fuel economy, small displacement four-cylinder engine has become popular, even class D luxury car has 2.0 T engine. Vehicle maintenance shows that its new four-cylinder engine can be compared with the smooth six-cylinder engine, but few people dare to take out the four-cylinder engine. The in-line six-cylinder engine competes smoothly together. Now the increasingly popular direct injection cylinder technology is seriously exploded and attacked, making engine vibration and noise more important.

　　我們都熟悉發動機氣缸的布局，它們大多是直線和v形的。然而，發動機氣缸數對發動機平整度的影響要比氣缸布置對發動機平整度的影響更為顯著。缸數越大，排量越大，對發動機的作用力越均勻，振動越小，進而運行噪聲相對降低。

　　We are all familiar with the layout of engine cylinders. Most of them are straight lines and V-shaped. However, the influence of cylinder number on engine flatness is more significant than that of cylinder arrangement. The larger the number of cylinders, the larger the displacement, the more uniform the force acting on the engine, the smaller the vibration, and the lower the running noise.

　　汽車氣缸的保養布局主要是為了節省空間，而不是為了平順。一般客車類的直列布局最多為六缸，可能不會出現8缸或8缸以上的直列布局，所以6缸以上的數量將選擇V或W型布局。

　　The maintenance layout of automobile cylinder is mainly for saving space, not for smoothness. Generally, the inline layout of passenger cars is at most six cylinders, and there may not be an inline layout of 8 cylinders or more, so the number of 6 cylinders or more will choose V or W type layout.

　　四沖程起動機首先要活塞上下往復運動和曲柄轉動運動。與起動機一起會受到活塞質量不均勻、旋轉不平衡質量、連桿質量不均勻、活塞曲柄安裝公差等制造誤差和材料密度的影響，從而變得難以解決振動問題。

　　Four-stroke starter first needs piston up and down reciprocating motion and crank rotation motion. Together with the starter, it will be affected by manufacturing errors such as uneven mass of piston, uneven mass of rotation, uneven mass of connecting rod, installation tolerance of piston crank and material density, which makes it difficult to solve the vibration problem.

　　當然，只要生產精度滿足均勻應力，就不會出現太多的不規則振蕩，這也就解決了為什么生產大品牌的發射機比較昂貴。四沖程發動機只有在工作時才產生動力，然后振動，使其在吸氣、收縮和排氣過程中平穩工作，甚至消耗能量。

　　Of course, as long as the production accuracy meets the uniform stress, there will not be too many irregular oscillations, which also solves why the production of large brand transmitters is more expensive. Four-stroke engine generates power only when it is working, and then vibrates, making it work smoothly in the process of suction, contraction and exhaust, even consuming energy.

　　四沖程起動器需要兩個曲柄旋轉周期，即720°，才能完成有效的工作量。四缸引發器在180°、720°的距離下進行焚燒，六缸引發器每120°進行一次焚燒。所以六缸機比四缸機功率密度要大，簡單地說汽車保養，振動更簡單平衡，然后平穩更好。

　　Four-stroke starter requires two crank rotation cycles, 720 degrees, to complete the effective workload. Four-cylinder initiator is incinerated at a distance of 180 degrees and 720 degrees, and six-cylinder initiator is incinerated every 120 degrees. So the power density of six-cylinder engine is higher than that of four-cylinder engine. Simply speaking, automobile maintenance, vibration is more simple and balanced, and then stable and better.

　　汽車維修時活塞上下往復運動會產生慣性力，與活塞一起作用在曲柄上就構成轉動慣性力和慣性矩。如何平衡這些力和扭矩成為平滑的關鍵。不得不承認，目前四缸發動機已經成為市場的主流，而且在舒適性方面發動機的振動已經得到了有效的控制，但是如果你達到六缸發動機的舒適性，那就是符合物理規律的。那么，為什么內聯的6臺機器能夠自己平衡這些力呢?

　　The reciprocating motion of piston will produce inertia force during automobile maintenance. Rotating inertia force and moment of inertia will be formed when piston acts on crank together with piston. How to balance these forces and torques becomes the key to smoothing. It has to be admitted that the four-cylinder engine has become the mainstream of the market at present, and the vibration of the engine in terms of comfort has been effectively controlled, but if you achieve the comfort of the six-cylinder engine, it is in accordance with the physical law. So why are the six inline machines able to balance these forces on their own?
