When buying automatic concrete mixer truck, they all want to choose the more powerful model. How to choose? Is it engine horsepower or torque? Automatic mixer manufacturers to explore this problem.

　　自动混凝土搅拌车功率是衡量车辆高速度的物理量，扭矩是衡量车辆加快能力的物理量，功率大的搅拌车的速度也大，扭矩大车辆的加快功能更好。功率是指物体在单位时间内所做的功，即功率是表明做功快慢的物理量。功率越大转速越高，车辆的高速度也越高，商用大功率来描绘车辆的动力功能。一般咱们常用大功率来描绘搅拌车的动力功能。大功率一般便是用马力来表明的，1马力等于0.735千瓦。扭矩在物理学中便是力矩的大小，等于力和力臂的乘积，国际单位是Nm。扭矩越高车辆运行的反响便越好。

　　The power of automatic concrete mixer truck is the physical quantity to measure the high speed of the vehicle, and the torque is the physical quantity to measure the acceleration ability of the vehicle. The speed of the mixer with high power is also large, and the acceleration function of the vehicle with large torque is better. Power refers to the work done by an object in unit time, that is, power is a physical quantity indicating the speed of work. The higher the power, the higher the speed, and the higher the high speed of the vehicle. Commercial high power is used to describe the power function of the vehicle. Generally we use high power to describe the power function of mixer. High power is generally indicated by horse power, 1 horsepower is equal to 0.735 kW. Torque in physics is the magnitude of torque, equal to the product of force and arm of force, the international unit is nm. The higher the torque, the better the response.

　　功率=力×速度，功率跟速度是有关系的，功率越大，车辆就跑的越快！

　　Power = force × speed, power is related to speed, the greater the power, the faster the vehicle will run!

　　扭矩=力×力臂，扭矩可理解为力，扭矩越大，发动机的力就越大。

　　Torque = force × arm, torque can be understood as force, the greater the torque, the greater the force of the engine.
            

　　加速度=力/质量

　　Acceleration = force / mass

　　由以上可以看出：发动机的扭矩越大，车辆的加速就越好，跑车之所以跑的快，就是因为其马力大，扭矩强的原因。

　　It can be seen from the above: the greater the torque of the engine, the better the acceleration of the vehicle. The reason why the sports car runs fast is because of its high horsepower and strong torque.

　　所以我们可以简单的理解为：扭矩决定了加速，马力决定了极速，购买自动搅拌车主要是看扭矩，因为扭矩大，加速性能就好。

　　So we can simply understand it as: the torque determines the acceleration, and the horsepower determines the extreme speed. The purchase of automatic mixer mainly depends on the torque. Because the torque is large, the acceleration performance is good.

　　马力和扭矩其实也是有联系的，功率=扭矩×转速/9550

　　Horsepower and torque are also related, power = torque × speed / 9550

　　自动搅拌车，在相同大功率输出下，大排量自吸比中小排量自吸起步和中段加速快；相同大功率输出下，涡轮增压比自然吸气起步和中段加速快；相同大功率输出下，柴油车比汽油车起步和中段加速快；相同大功率输出下，电动车加速比汽油车、柴油车快。自动混凝土搅拌车主要还是力，也就是扭矩，扭矩大，整车劲儿就大。

　　Under the same high power output, the large displacement self-priming is faster than the small and medium displacement self-priming; under the same high power output, the turbocharged is faster than the natural suction; under the same high power output, the diesel is faster than the gasoline; under the same high power output, the electric vehicle is faster than the gasoline and diesel. The torque of the whole vehicle is high, that is to say, the power of the concrete mixer is high.
