ABSTRACT:
This apparatus equally divides an injection period TAU into three periods; i.e., front, intermediate, and rear periods, and assumes that first injection (mass Q(1)) corresponding to the “front period” is executed at one time at a fuel injection start timing, second injection (mass Q(2)) corresponding to the “intermediate period” is executed at one time when ⅓ TAU has elapsed after the first injection, and third injection (mass Q(3)) corresponding to the “rear period” is executed at one time when ⅓ TAU has elapsed after the second injection. A first gas mixture based on the first injection, a second gas mixture based on the second injection, and a third gas mixture based on the third injection are individually handled, and the excess air ratio of gas mixture, the state (temperature, etc.) of gas mixture, and the emission generation amounts in gas mixture are estimated for each gas mixture.
