1. engine control system that is used for homogeneous charge compression ignition formula (HCCI) motor, it comprises:

  • Position determination module, described position determination module are determined the initial position of EGR valve based on the predefined function of exhaust gas recirculation (EGR) flow, air-distributor pressure, exhaust manifold pressure and the exhaust gas temperature of expectation;

    The position correction module, described position correction module is determined the position correction of described EGR valve based on the pressure in the cylinder of described hcci engine;

    AndThe valve control module, described valve control module instructs described EGR valve to described initial position between the tour that is burned to the HCCI burning from spark ignition type (SI), and the described EGR valve of instruction is to the final position in the scheduled time slot after described transformation, wherein, described final position comprises the summation of described initial position and described position correction.
