How does hydraulic cam and groove coupling work together with the diesel engine?

　　In Figure, parabola represents input characteristic curve when the hydraulic cam and groove coupling is in different ispeeds and different slip condition, relatively flat curve is external characteristic curve of diesel engine, a curve is the intersection of the two joint working point.

　　From the performance curve, it can be seen, when the engine speed is rated at the turn, input speed of hydraulic cam and groove coupling is equal to the rated engine speed, slip ratio is 1.5%, the output speed is input speed 98.5%. When the load is increased, the role of increased large torque hydraulic cam and groove coupling in the output shaft, need to transfer more torque motivation, so, diesel engine rotate along characteristic curve to the velocity direction, in order to increase the torque to reach a new equilibrium.

　　And opposite diesel speed down telephoto, Ffuid cam and groove coupling torque transmission capacity is proportional to the square of its speed, when the input speed (i.e., when the engine speed is reduced greatly after), torque coupler to reduce, not in the original rated condition, then along the curve to reduce speed, to increase the speed ratio, improve the torque direction, know can balance and balance torque, establish the operating point of the new and the diesel engine.

　　If the load continues to increase, the rotation speed of the diesel engine will continue to decline, driving torque curve and hydraulic cam and groove coupling 100% slip is =0 working curve. At this time, the diesel engine to maintain a low speed operation but not to extinguish, and output speed of hydraulic cam and groove coupling is zero.
