Abstract： |
The invention provides a motor jet and ignition control device based on absolute crankshaft turn angle senor, belonging to the motor electronic control technology. It includes absolute turn angle sensor, camshaft signal sensor, D flip-flop, comparators, logic gate and SCM. The output end of absolute turn angle sensor is connected with the input end of D flip-flop. SCM PWM output module is connected with the output end of absolute turn angle sensor and the time input of D flip-flop. The camshaft signal sensor is connected with the first data input of SCM. The D flip-flop is connected with the input P of the beginning comparator, the input P of the ending comparator and the second data input of SCM. The valve output and non-gate output are connected with 0 and input. The first and output is connected with the input of single pump drive circuit. The invention improves the jet control precision of motor, simplifies the injection program, reduces the demand of SCM operation and provides more functions for motor management system.. |
