Abstract

Abstract

The bench test of electronic control gasoline engine was carried out, the nonlinear character of engine intake system was taken into account, the relation between manifold pressure and intake system parameters was given based on engine intake dynamic model. According to the application trait of Kalman filter, an estimate method of engine intake flowrate was put forward based on extended Kalman filter (EKF), the iterative equation was obtained by the simple linearization of nonlinear system, the intake pressures of transient operation condition were computed with different load rates. The comparison result of computation value and measure value shows that their deviation is within 3% for low load ratio, and has increasing tendency for high load ratio, but it is within 5%. The result indicates that the method can compute engine transient intake quantity exactly.
