Filed: 2002-07-15
Abstract: <P>PROBLEM TO BE SOLVED: To estimate residue gas amount with high precision in an internal combustion engine equipped with a variable valve mechanism which varies the valve-lift amount of an intake valve.  <P>SOLUTION: On the basis of a valve opening area AWm during valve overlapping calculated from the valve-lift amount (VCS-ANGL) of the intake valve and a valve-opening timing IVO, a basic blowback amount WmO during the valve overlapping is calculated (d10 portion, d11 portion). By applying intake pressure correction (d12 portion) and rotational speed correction (d13 portion) to the basic blowback amount WmO, a blowback residue gas amount Wm is calculated. On the other hand, a basic residue gas amount Wcyl obtained when there is no valve overlapping based on an actual engine basic volume flow rate RQHOVEL1 calculated from the valve-lift amount and the valve opening timing, is calculated (d14 portion, d15 portion). By adding the blowback residue gas amount Wm and the basic residue gas amount Wcyl, a total residue gas amount W is calculated (d16 portion).  <P>COPYRIGHT: (C)2004,JPO
