A Study on Ignition Advanced Angle Control Strategy of EFI Gasoline Engine 2010-01-0244

Taking LJ377MV motorcycle engine for a research object, this paper designs and simulates the control strategy of ignition advanced angle in various work conditions. The analysis of closed-loop control of ignition advanced angle based on knock signal and the control strategy of idle condition are emphasized. In order to achieve modularization of electronic control system development and reduce costs, Stateflow and Simulink in the MATLAB software platform are used to complete the modeling and simulation of ignition advanced angle controller. The simulation results verify the rationality of control strategy which has been designed in the paper and also indicate that the idle speed can be stabilized at desired speed by the adjustment of ignition advanced angle controlled by sliding mode variable structure.
