Control method of dynamic optimization search operating the engine servo load device and this device

摘要

The dynamic optimization search method in the torque servo load device of the engine is disclosed. The torque servo load device, the electric motor and the torque servo driver, includes main control unit, and the mass flow rate sensor. Main control unit, among those, remembers the data of fuel consumption value per unit of mechanical power of the engine at each place of optimum efficiency Operating curve and this curved line of the engine. Under process and the optimization search torque to which dynamic optimization search method following to process and the present optimum efficiency Operating curve which detect the present operational parameter of the engine, changes present optimum fuel efficiency torque with process and the optimization search step which operate the engine, obtains optimization search torque, the fuel consumption value to which the area of unit of process and calculate the fuel consumption value around unit of mechanical power of the engine process and the mechanical power which operate the engine at optimization search measurement - calculation period was calculated, the fuel where the area of unit of mechanical power is rememberedThe fuel consumption value to which the area of unit of process and the mechanical power which are compared with consumption value was calculated, when it is smaller than the fuel consumption value to which the area of unit of mechanical power is remembered, you remember the optimization search torque in optimum efficiency Operating curve, the process which remembers the fuel consumption value to which the area of unit of mechanical power was calculated and, you have.
