| Abstract: | According to the technical requirements and features of solenoid valve drive for electronically controlled injector,a circuit module of injector driving based on SCM XC2765 was designed,which was controlled by high-side and low-side of low-power microcontroller.With the designed high-side and low-side control and DA output high and low voltage level control technology,the solenoid valve coil current and fuel injection effect were verified and researched.In the experiment,the module realized the 15 A upgrading and 6 A maintaining of drive current and shortened the opening time and closing time of solenoid valve that were reduced to 0.20 ms and 0.35 ms respectively,which met the requirements of the solenoid valve drive. |
