搅拌车中冷增压发动机是什么原理？

搅拌车是在建筑工地常见的一种专用车辆，建筑工地上一般路况都不好，而搅拌车因为运输介质是混凝土，重量又比较大，所以在发动机的选择上多选马力大，动力足的，在购买车辆的时候，我们常常听说中冷增压发动机、涡轮增压发动机，那么搅拌车的中冷增压发动机是什么样的工作原理呢？为什么会选中冷增压发动机呢

Mixer is the most common special vehicle in construction site. The general road condition on construction site is not good. Because the transportation medium of mixer is concrete and its weight is relatively large, the selection of engine with high horsepower and sufficient power is preferred. When purchasing vehicles, we often hear that the intercooled turbocharged engine and turbocharged engine increase the intercooling of the mixer What is the working principle of compression engine? Why choose the cold supercharged engine

中冷增压就是当涡轮增压器将新鲜空气压缩经中段冷却器冷却，然后经进气管、进气门流汽缸燃烧室。有效的中冷技术可使增压温度下降到50摄氏度以下，有助于减少废气的排放和提高燃油的经济性。

Intercooling pressurization is when the turbocharger compresses the fresh air, which is cooled by the middle cooler, and then flows to the cylinder combustion chamber through the intake pipe and intake valve. Effective intercooling technology can reduce the supercharging temperature to below 50 ℃, which helps to reduce exhaust emissions and improve fuel economy.

中冷增压实际上是一种空气压缩机，通过压缩空气来增加进气量，它是利用发动机排出的废气惯性冲力来推动涡轮室内的涡轮，涡轮又带动同轴的叶轮，叶轮压送空气滤清器送来的空气，使之增压进入气缸。当发动机转速增快，废气排出速度与涡轮转速也同步增快，叶轮就压缩更多的空气进入气缸，空气的压力和密度增大可以燃烧更多的燃料，相应增加燃料和调整一下发动机的转速，就可以增加发动机的输出功率。

Intercooled supercharging is actually an air compressor, which can increase the air intake through compressed air. It uses the inertia impulse of exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller. The impeller presses the air from the air filter to increase the pressure into the cylinder. When the engine speed increases, the exhaust gas exhaust speed and turbine speed also increase synchronously, the impeller compresses more air into the cylinder, the air pressure and density increase, more fuel can be burned, and the output power of the engine can be increased by increasing the fuel and adjusting the engine speed.

中冷增压系统平时是不工作的，只有当车辆满载或者达到一定的速度时，中冷增压可以是柴油机在排量不变，重量增加不大的情况下达到增加输出功率的目的，与相同功率的非增压柴油机相比，增压柴油机不仅体积小，重量轻，功率大，而且还降低了单位功率的成本，因此，增压技术不仅广泛应用在柴油机上，现在很多燃油为汽油的车辆也在使用中冷增压系统，它是改善内燃发动机的重要技术手段。

Intercooled turbocharging system usually does not work. Only when the vehicle is fully loaded or reaches a certain speed, intercooled supercharging can increase the output power of diesel engine under the condition of constant displacement and small weight increase. Compared with non supercharged diesel engine with the same power, supercharged diesel engine is not only small in size, light in weight and high in power, but also reduces the percentage of unit power Therefore, supercharging technology is not only widely used in diesel engines, but also used in many gasoline fueled vehicles. It is an important technical means to improve the internal combustion engine.
