Speed control system design ETC
Abstract：Reduce the engine emissions and noise pollution so as to meet the people's demand for environmental protection and cut off fuel consumption and meet people's goal of reducing the use of cost has always been the pursuit of engine researchers and manufacturers. Especially as China Ⅲ emission regulations and the implementation of the limit. R & D personnel not only continue to improve the engine emission performance but also other factors that affect the engine emissions levels to give great attention. Because diesel engine has the characteristics of great torque and good economic performance, it is widely used in automobile and large diesel equipment. Nowadays, In the factory, the speed and torque are controlled by the PID parameters kp,ki,kd respectively for ETC test of diesel engine. But the speed and torque of the coupling relationship and the fuel consumption of the control requirements are increasingly high. The purpose of this thesis is to get the appropriate throttle opening to control the speed and achieve the energy saving and emission reduction by reasonable algorithm. 源`自*六)维[论*文'网www.lwfree.cn
For modeling of diesel engine is in order to better realize the speed control, this topic through establish reasonable model to realize accurate adjustment speed and the optimal control of fuel consumption. It has important engineering value and promotion prospects.
